Object Creation

obj = chilkat.CkHttp()

Properties

AbortCurrent

# boolVal is a boolean
boolVal = http.get_AbortCurrent();
http.put_AbortCurrent(boolVal);

Introduced in version 9.5.0.58

When set to True, causes the currently running method to abort. Methods that always finish quickly (i.e.have no length file operations or network communications) are not affected. If no method is running, then this property is automatically reset to False when the next method is called. When the abort occurs, this property is reset to False. Both synchronous and asynchronous method calls can be aborted. (A synchronous method call could be aborted by setting this property from a separate thread.)

Accept

# strVal is a string
# ckStr is a CkString
http.get_Accept(ckStr);
strVal = http.ck_accept();
http.put_Accept(strVal);

The Accept header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is "*/*".

AcceptCharset

# strVal is a string
# ckStr is a CkString
http.get_AcceptCharset(ckStr);
strVal = http.acceptCharset();
http.put_AcceptCharset(strVal);

The Accept-Charset header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is the empty string, which means no Accept-Charset header is included.

AcceptLanguage

# strVal is a string
# ckStr is a CkString
http.get_AcceptLanguage(ckStr);
strVal = http.acceptLanguage();
http.put_AcceptLanguage(strVal);

The Accept-Language header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is "en-us,en;q=0.5".

AllowGzip

# boolVal is a boolean
boolVal = http.get_AllowGzip();
http.put_AllowGzip(boolVal);

Controls whether the "Accept-Encoding: gzip" header is added to HTTP requests sent via any method that sends an HTTP request without using the HttpRequest object (such as QuickGetStr). If False, then the empty Accept-Encoding header is added which means the server response should contain the uncompressed content. The default value is True, which means the server, if it chooses, may send a gzipped response.

AllowHeaderFolding

# boolVal is a boolean
boolVal = http.get_AllowHeaderFolding();
http.put_AllowHeaderFolding(boolVal);

Introduced in version 9.5.0.63

If this property is set to False, then no MIME header folding will be automatically applied to any request header. The default is True.

AuthSignature

# strVal is a string
# ckStr is a CkString
http.get_AuthSignature(ckStr);
strVal = http.authSignature();
http.put_AuthSignature(strVal);

Introduced in version 9.5.0.89

If set, then automatically adds the Authorization: Signature keyId="...", algorithm="...", headers="...", signature="..." header to all requests. This property should be set to a JSON string containing the information needed to compute and automatically add the HTTP Signature. See the example(s) below.

AuthToken

# strVal is a string
# ckStr is a CkString
http.get_AuthToken(ckStr);
strVal = http.authToken();
http.put_AuthToken(strVal);

Introduced in version 9.5.0.67

If set, then automatically adds the "Authorization: Bearer " header to all requests. (If you have an OAuth2 access token, set this property equal to the OAuth2 access token string. Note: For OAuth1 (older) tokens, use the OAuthTOken property. )

More Information and Examples

AutoAddHostHeader

# boolVal is a boolean
boolVal = http.get_AutoAddHostHeader();
http.put_AutoAddHostHeader(boolVal);

If set to true, the "Host" header field will automatically be added to the request header for any QuickGet or QuickGetStr method calls. The value of the Host header field is taken from the hostname part of the URL passed to QuickGet/QuickGetStr.

AwsAccessKey

# strVal is a string
# ckStr is a CkString

Introduced in version 9.5.0.56

The AWS (S3) region, such as "us-east-1", "us-west-2", "eu-west-1", "eu-central-1", etc. This propery defaults to "us-east-1". It is only used when the AwsSignatureVersion property is set to 4. When the AwsSignatureVersion property is set to 2, then this property is unused.

AwsSecretKey

# strVal is a string
# ckStr is a CkString
http.get_AwsSecretKey(ckStr);
strVal = http.awsSecretKey();
http.put_AwsSecretKey(strVal);

The AWS Secret Key to be used with the Amazon S3 methods listed below.

strVal = http.awsSessionToken();
http.put_AwsSessionToken(strVal);

Introduced in version 9.5.0.95

This is only used if a set of temporary security credentials were obtained by calling the AssumeRole action of the AWS Security Token Service.

AwsSignatureVersion

# intVal is an integer
intVal = http.get_AwsSignatureVersion();
http.put_AwsSignatureVersion(intVal);

Introduced in version 9.5.0.56

Selects the AWS Signature Version algorithm. The default value is 4. May be set to 2 to select AWS Signature Version 2. (The only valid choices are 2 and 4.)

http.get_AwsSubResources(ckStr);
strVal = http.awsSubResources();
http.put_AwsSubResources(strVal);

The AWS sub-resources to be used with the Amazon S3 methods listed below.

If the S3 request needs to address a sub-resource, like ?versioning, ?policy, ?location, ?acl, or ?torrent, or ?versionid append the sub-resource and its value if it has one. Note that in case of multiple sub-resources, sub-resources must be lexicographically sorted by sub-resource name and separated by '&'. e.g. "acl&versionId=value"

The list of sub-resources that can be included are: acl, location, logging, notification, partNumber, policy, requestPayment, torrent, uploadId, uploads, versionId, versioning, versions and website.

BandwidthThrottleDown

# intVal is an integer
intVal = http.get_BandwidthThrottleDown();
http.put_BandwidthThrottleDown(intVal);

Introduced in version 9.5.0.49

If non-zero, limits (throttles) the download bandwidth to approximately this maximum number of bytes per second. The default value of this property is 0.

BandwidthThrottleUp

# intVal is an integer
intVal = http.get_BandwidthThrottleUp();
http.put_BandwidthThrottleUp(intVal);

Introduced in version 9.5.0.49

If non-zero, limits (throttles) the upload bandwidth to approximately this maximum number of bytes per second. The default value of this property is 0.

BasicAuth

# boolVal is a boolean
boolVal = http.get_BasicAuth();
http.put_BasicAuth(boolVal);

If HTTP basic authentication is needed, this property must be set to True. The HTTP protocol allows for several different types of authentication schemes, such as NTLM, Digest, OAuth1, etc. A given server will support (or allow) certain authentication schemes (also known as authentication methods). Except for the "Basic" authentication method, the other forms of authentication do not involve sending the login and password in plain unencrypted text over the connection. The Basic authentication method is insecure in that it sends the login/password for all to see. If the connection is SSL/TLS, then this might be considered OK. Chilkat takes the safe approach and will not allow Basic authentication unless this property has been explicitly set to True. The default value of this property is False.

Note: It is not required to know the authentication methods accepted by the server beforehand (except for the case of Basic authentication). When authentication is required, Chilkat will first send the request without the Authorization header, receive back the 401 Authorization Required response along with information about what authentication methods are accepted, and then re-send with an accepted authentication method. If the authentication method is known in advance, then an application may set the appropriate property, such as NtlmAuth to True so that the extra (internal) round-trip is not required.

Note: The login and password is sent using the utf-8 byte representation. Some servers expect the ANSI byte representation (typically Windows-1252). Starting in Chilkat v9.5.0.87, to send the login/password using ANSI, add the "AnsiLogin" keyword to the UncommonOptions property.

ClientIpAddress

# strVal is a string
# ckStr is a CkString
http.get_ClientIpAddress(ckStr);
strVal = http.clientIpAddress();
http.put_ClientIpAddress(strVal);

The IP address to use for computers with multiple network interfaces or IP addresses. For computers with a single network interface (i.e. most computers), this property should not be set. For multihoming computers, the default IP address is automatically used if this property is not set.

The IP address is a string such as in dotted notation using numbers, not domain names, such as "165.164.55.124".

ConnectFailReason

# intVal is an integer
intVal = http.get_ConnectFailReason();

Introduced in version 9.5.0.56

This property will be set to the status of the last HTTP connection made (or failed to be made) by any HTTP method.

Possible values are:

0 = success

Normal (non-TLS) sockets:
1 = empty hostname
2 = DNS lookup failed
3 = DNS timeout
4 = Aborted by application.
5 = Internal failure.
6 = Connect Timed Out
7 = Connect Rejected (or failed for some other reason)
50 = HTTP proxy authentication failure.
98 = Async operation in progress.
99 = Product is not unlocked.

SSL/TLS:
100 = TLS internal error.
101 = Failed to send client hello.
102 = Unexpected handshake message.
103 = Failed to read server hello.
104 = No server certificate.
105 = Unexpected TLS protocol version.
106 = Server certificate verify failed (the server certificate is expired or the cert's signature verification failed).
107 = Unacceptable TLS protocol version.
108 = App-defined server certificate requirements failure.
109 = Failed to read handshake messages.
110 = Failed to send client certificate handshake message.
111 = Failed to send client key exchange handshake message.
112 = Client certificate's private key not accessible.
113 = Failed to send client cert verify handshake message.
114 = Failed to send change cipher spec handshake message.
115 = Failed to send finished handshake message.
116 = Server's Finished message is invalid.
125 = Peer tried to connect using older SSL 2.0 protocol version.
126 = TLS Pin Set Mismatch.
127 = TLS 1.3 handshake error.

Connection

# strVal is a string
# ckStr is a CkString
http.get_Connection(ckStr);
strVal = http.connection();
http.put_Connection(strVal);

The Connection header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is "Keep-Alive". To prevent the Connection header from being added to the HTTP header, set this property to the empty string.

ConnectTimeout

# intVal is an integer
intVal = http.get_ConnectTimeout();
http.put_ConnectTimeout(intVal);

The amount of time in seconds to wait before timing out when connecting to an HTTP server. The default ConnectTimeout is 30 seconds.

Note: This is the maximum number of seconds to wait for a server to accept a TCP connection. Once the connection is accepted, and bytes begin flowing back-and-forth, then it is the ReadTimeout property that applies. It is the ReadTimeout that applies when receiving data, which includes the reads that occur during a TLS handshake.

CookieDir

# strVal is a string
# ckStr is a CkString
http.get_CookieDir(ckStr);
strVal = http.cookieDir();
http.put_CookieDir(strVal);

Specifies a directory where cookies are automatically persisted if the Http.SaveCookies property is turned on. Cookies are stored in XML formatted files, one per domain, to main it easy for other programs to understand and parse. May be set to the string "memory" to cache cookies in memory.

More Information and Examples

Caching cookies in-memory.

DebugLogFilePath

# strVal is a string
# ckStr is a CkString
http.get_DebugLogFilePath(ckStr);
strVal = http.debugLogFilePath();
http.put_DebugLogFilePath(strVal);

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
there is an internal problem (bug) in the Chilkat code that causes the hang.

More Information and Examples

DefaultFreshPeriod

# intVal is an integer
intVal = http.get_DefaultFreshPeriod();
http.put_DefaultFreshPeriod(intVal);

The default freshness period (in minutes) for cached documents when the FreshnessAlgorithm property is set to 0. The default value is 10080 (1 week).

DigestAuth

# boolVal is a boolean
boolVal = http.get_DigestAuth();
http.put_DigestAuth(boolVal);

Setting this property to True causes the HTTP component to use digest authentication. The default value is False.

FetchFromCache

# boolVal is a boolean
boolVal = http.get_FetchFromCache();
http.put_FetchFromCache(boolVal);

Set to true if pages should be fetched from cache when possible. Only HTTP GET requests are cached. HTTP responses that include Set-Cookie headers are not cached. A page is fetched from the disk cache if it is present and it is "fresh" according to the FreshnessAlgorithm property. If a page exists in cache but is not fresh, the HTTP component will issue a revalidate request and update the cache appropriately according to the response.

FinalRedirectUrl

# strVal is a string
# ckStr is a CkString
http.get_FinalRedirectUrl(ckStr);
strVal = http.finalRedirectUrl();

If an HTTP GET was redirected (as indicated by the WasRedirected property), this property will contain the final redirect URL, assuming the FollowRedirects property is True.

Note: Starting in v9.5.0.49, this property will contain the redirect URL for 301/302 responses even if FollowRedirects is not set to True.

FollowRedirects

# boolVal is a boolean
boolVal = http.get_FollowRedirects();
http.put_FollowRedirects(boolVal);

If true, then 301, 302, 303, 307, and 308 redirects are automatically followed when calling QuickGet and QuickGetStr. FollowRedirects is true by default.

FreshnessAlgorithm

# intVal is an integer
intVal = http.get_FreshnessAlgorithm();
http.put_FreshnessAlgorithm(intVal);

The freshness algorithm to use when determining the freshness of a cached HTTP GET response. A value of 1 causes an LM-factor algorithm to be used. This is the default. The LMFactor property is a value between 1 and 100 indicating the percentage of time based on the last-modified date of the HTML page. For example, if the LMFactor is 50, and an HTML page was modified 10 days ago, then the page will expire (i.e. no longer be fresh) in 5 days (50% of 10 days). This only applies to HTTP responses that do not have page expiration information. If the FreshnessAlgorithm = 0, then a constant expire time period determined by the DefaultFreshPeriod property is used.

IgnoreMustRevalidate

# boolVal is a boolean
boolVal = http.get_IgnoreMustRevalidate();
http.put_IgnoreMustRevalidate(boolVal);

Some HTTP responses contain a "Cache-Control: must-revalidate" header. If this is present, the server is requesting that the client always issue a revalidate HTTP request instead of serving the page directly from cache. If IgnoreMustRevalidate is set to True, then Chilkat HTTP will serve the page directly from cache without revalidating until the page is no longer fresh.

The default value of this property is False.

IgnoreNoCache

# boolVal is a boolean
boolVal = http.get_IgnoreNoCache();
http.put_IgnoreNoCache(boolVal);

Some HTTP responses contain headers of various types that indicate that the page should not be cached. Chilkat HTTP will adhere to this unless this property is set to True.

The default value of this property is False.

KeepResponseBody

# boolVal is a boolean
boolVal = http.get_KeepResponseBody();
http.put_KeepResponseBody(boolVal);

Introduced in version 9.5.0.55

If True, then the response body, if text, is saved to the LastResponseBody property for all methods that do not return an HttpResponse object. The default value of this property is False.

LastContentType

# strVal is a string
# ckStr is a CkString
http.get_LastContentType(ckStr);
strVal = http.lastContentType();

The content-type of the last HTTP response received by the HTTP component.

LastErrorHtml

# strVal is a string
# ckStr is a CkString
http.get_LastErrorHtml(ckStr);
strVal = http.lastErrorHtml();

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

LastErrorText

# strVal is a string
# ckStr is a CkString
http.get_LastErrorText(ckStr);
strVal = http.lastErrorText();

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

LastErrorXml

# strVal is a string
# ckStr is a CkString
http.get_LastErrorXml(ckStr);
strVal = http.lastErrorXml();

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

LastFromCache

# boolVal is a boolean
boolVal = http.get_LastFromCache();

Introduced in version 9.5.0.91

True if the last GET was fetched from cache.

More Information and Examples

Fetch Web Pages from Local Cache

LastHeader

# strVal is a string
# ckStr is a CkString
http.get_LastHeader(ckStr);
strVal = http.lastHeader();

The text of the last HTTP header sent by any of this class's methods. The purpose of this property is to allow the developer to examine the exact HTTP header for debugging purposes.

LastMethodSuccess

# boolVal is a boolean
boolVal = http.get_LastMethodSuccess();
http.put_LastMethodSuccess(boolVal);

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

Any method that returns a string.
Any method returning a Chilkat object, binary bytes, or a date/time.
Any method returning a standard boolean status value where success = True and failure = False.
Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

LastModDate

# strVal is a string
# ckStr is a CkString
http.get_LastModDate(ckStr);
strVal = http.lastModDate();

The value of the Last-Modified header in the last HTTP response received by the HTTP component.

LastResponseBody

# strVal is a string
# ckStr is a CkString
http.get_LastResponseBody(ckStr);
strVal = http.lastResponseBody();

Introduced in version 9.5.0.55

The response body of the last HTTP response received by the HTTP component (for methods that do not return an HttpResponse object). The last response body is only saved to this property IF the KeepResponseBody property is set to True.

LastResponseHeader

# strVal is a string
# ckStr is a CkString
http.get_LastResponseHeader(ckStr);
strVal = http.lastResponseHeader();

The entire response header for the last HTTP response received by the HTTP component (for methods that do not return an HttpResponse object).

More Information and Examples

Get Response Header for Method that does not Return HttpResponse Object

LastStatus

# intVal is an integer
intVal = http.get_LastStatus();

The last HTTP status value received by the HTTP component. This only applies to methods that do not return an HTTP response object. For methods that return an HTTP response object, such as SynchronousRequest, the status code is found in the StatusCode property of the response object.

LastStatusText

# strVal is a string
# ckStr is a CkString
http.get_LastStatusText(ckStr);
strVal = http.lastStatusText();

Introduced in version 9.5.0.69

The last HTTP status text received by the HTTP component. This only applies to methods that do not return an HTTP response object. For methods that return an HTTP response object, such as SynchronousRequest, the status text is found in the StatusText property of the response object.

LMFactor

# intVal is an integer
intVal = http.get_LMFactor();
http.put_LMFactor(intVal);

An integer between 1 and 100 that indicates the percentage of time from the HTTP page's last-modified date that will be used for the freshness period. The default value is 25. For example, if a page is fetched with a last-modified date of 4 weeks ago, and the LMFactor = 25, then the page will be considered fresh in the cache for 1 week (25% of 4 weeks).

Login

# strVal is a string
# ckStr is a CkString
http.get_Login(ckStr);
strVal = http.login();
http.put_Login(strVal);

The HTTP login for pages requiring a login/password. Chilkat HTTP can do Basic, Digest, and NTLM HTTP authentication. (NTLM is also known as SPA (or Windows Integrated Authentication). To use Basic authentication, the BasicAuth property must be set equal to True. It is not necessary to set the NtlmAuth or DigestAuth properties beforehand if NTLM or Digest authentication is needed. However, it is most efficient to pre-set these properties when the type of authentication is known in advance.

Important: If NTLM authentication is used, it may be incorrect to set the Login property equal to "mydomain\mylogin". Instead, set the LoginDomain property equal to "mydomain", and set this property equal to "mylogin".

Note: When the Login and Password properties are set, and the type of authentication is specified by setting one of the following properties equal to True (BasicAuth, DigestAuth, NtlmAuth), Chilkat will automatically add the "Authorization: ..." header in the correct format.

More Information and Examples

HTTP Authentication (Basic, NTLM, Digest, Negotiate)

LoginDomain

# strVal is a string
# ckStr is a CkString
http.get_LoginDomain(ckStr);
strVal = http.loginDomain();
http.put_LoginDomain(strVal);

The optional domain name to be used with NTLM / Negotiate authentication.

MaxConnections

# intVal is an integer
intVal = http.get_MaxConnections();
http.put_MaxConnections(intVal);

The maximum number of simultaneous open HTTP connections managed by the HTTP component. The Chilkat HTTP component automatically manages HTTP connections. If the number of open HTTP connections is about to be exceeded, the connection with the least recent activity is automatically closed.

MaxFreshPeriod

# intVal is an integer
intVal = http.get_MaxFreshPeriod();
http.put_MaxFreshPeriod(intVal);

Limits the amount of time a document can be kept "fresh" in the cache. The MaxFreshPeriod is specified in minutes, and the default value is 525600 which is equal to 1 year.

MaxResponseSize

# intVal is a unsigned long
intVal = http.get_MaxResponseSize();
http.put_MaxResponseSize(intVal);

The maximum HTTP response size to be accepted by the calling program. A value of 0 (the default) indicates that there is no maximum value.

MaxUrlLen

# intVal is an integer
intVal = http.get_MaxUrlLen();
http.put_MaxUrlLen(intVal);

The Http class will automatically fail any URL longer than this length. The default MaxUrlLen is 2000 characters.

MimicFireFox

# boolVal is a boolean
boolVal = http.get_MimicFireFox();
http.put_MimicFireFox(boolVal);

If set to True, then the appropriate headers to mimic Mozilla/FireFox are automatically added to requests sent via the QuickGet and QuickGetStr methods.

MimicIE

# boolVal is a boolean
boolVal = http.get_MimicIE();
http.put_MimicIE(boolVal);

If set to True, then the appropriate headers to mimic Internet Explorer are automatically added to requests sent via the QuickGet and QuickGetStr methods.

MinFreshPeriod

# intVal is an integer
intVal = http.get_MinFreshPeriod();
http.put_MinFreshPeriod(intVal);

The freshness period for a document in cache will not be less than this value (in minutes). The default value is 30.

NegotiateAuth

# boolVal is a boolean
boolVal = http.get_NegotiateAuth();
http.put_NegotiateAuth(boolVal);

Set this property equal to True for Negotiate authentication.

Note: The NegotiateAuth property is only available for the Microsoft Windows operating system.

NtlmAuth

# boolVal is a boolean
boolVal = http.get_NtlmAuth();
http.put_NtlmAuth(boolVal);

Setting this property to True causes the HTTP component to use NTLM authentication (also known as IWA -- or Integrated Windows Authentication) when authentication with an HTTP server. The default value is False.

More Information and Examples

NumCacheLevels

# intVal is an integer
intVal = http.get_NumCacheLevels();
http.put_NumCacheLevels(intVal);

The number of directory levels to be used under each cache root. The default is 0, meaning that each cached HTML page is stored in a cache root directory. A value of 1 causes each cached page to be stored in one of 255 subdirectories named "0","1", "2", ..."255" under a cache root. A value of 2 causes two levels of subdirectories ("0..255/0..255") under each cache root. The HTTP control automatically creates subdirectories as needed. The reason for mutliple levels is to alleviate problems that may arise with unrelated software when huge numbers of files are stored in a single directory. For example, Windows Explorer does not behave well when trying to display the contents of directories with thousands of files.

More Information and Examples

Fetch Web Pages from Local Cache

NumCacheRoots

# intVal is an integer
intVal = http.get_NumCacheRoots();

The number of cache roots to be used for the HTTP cache. This allows the disk cache spread out over multiple disk drives. Each cache root is a string indicating the drive letter and directory path. For example, "E:\Cache". An example of a very large low-cost cache might be four USB external drives. To create a cache with four roots, call AddCacheRoot once for each directory root.

OAuth1

# boolVal is a boolean
boolVal = http.get_OAuth1();
http.put_OAuth1(boolVal);

If True then causes an OAuth Authorization header to be added to any request sent by the HTTP object. For example:

Authorization: OAuth realm="http://sp.example.com/",
                oauth_consumer_key="0685bd9184jfhq22",
                oauth_token="ad180jjd733klru7",
                oauth_signature_method="HMAC-SHA1",
                oauth_signature="wOJIO9A2W5mFwDgiDvZbTSMK%2FPY%3D",
                oauth_timestamp="137131200",
                oauth_nonce="4572616e48616d6d65724c61686176",
                oauth_version="1.0"

The information used to compute the OAuth Authorization header is obtained from the other OAuth* properties, such as OAuthConsumerKey, OAuthConsumerSecret, OAuthRealm, etc.

# ckStr is a CkString
http.get_OAuthCallback(ckStr);
strVal = http.oAuthCallback();
http.put_OAuthCallback(strVal);

Introduced in version 9.5.0.53

http.get_OAuthSigMethod(ckStr);
strVal = http.oAuthSigMethod();
http.put_OAuthSigMethod(strVal);

The OAuth signature method, such as "HMAC-SHA1" to be used in the Authorization header. The default is "HMAC-SHA1". It is also possible to choose "HMAC-SHA256", "RSA-SHA1" or "RSA-SHA2". For RSA algorithms, an RSA private key would need to be provided via the SetOAuthRsaKey method.

Note: RSA-SHA2 is supported starting in Chilkat v9.5.0.56

OAuthToken

# strVal is a string
# ckStr is a CkString
http.get_OAuthToken(ckStr);
strVal = http.oAuthToken();
http.put_OAuthToken(strVal);

The OAuth verifier to be used in the Authorization header.

Password

# strVal is a string
# ckStr is a CkString
http.get_Password(ckStr);
strVal = http.password();
http.put_Password(strVal);

The HTTP password for pages requiring a login/password. Chilkat HTTP can do Basic, Digest, and NTLM HTTP authentication. (NTLM is also known as SPA (or Windows Integrated Authentication). To use Basic authentication, the BasicAuth property must be set equal to True. It is not necessary to set the NtlmAuth or DigestAuth properties beforehand if NTLM or Digest authentication is needed. However, it is most efficient to pre-set these properties when the type of authentication is known in advance.

Note: When the Login and Password properties are set, and the type of authentication is specified by setting one of the following properties equal to True (BasicAuth, DigestAuth, NtlmAuth), Chilkat will automatically add the "Authorization: ..." header in the correct format.

PreferIpv6

# boolVal is a boolean
boolVal = http.get_PreferIpv6();
http.put_PreferIpv6(boolVal);

If True, then use IPv6 over IPv4 when both are supported for a particular domain. The default value of this property is False, which will choose IPv4 over IPv6.

ProxyAuthMethod

# strVal is a string
# ckStr is a CkString
http.get_ProxyAuthMethod(ckStr);
strVal = http.proxyAuthMethod();
http.put_ProxyAuthMethod(strVal);

Set this to "basic" if you know in advance that Basic authentication is to be used for the HTTP proxy. Otherwise leave this property unset. Note: It is not necessary to set this property. The HTTP component will automatically handle proxy authentication for any of the supported authentication methods: NTLM, Digest, or Basic. Setting this property equal to "basic" prevents the 407 response which is automatically handled internal to Chilkat and never seen by your application.

Note: If NTLM authentication does not succeed, set the Global.DefaultNtlmVersion property equal to 1 and then retry.

ProxyDirectTls

# boolVal is a boolean
boolVal = http.get_ProxyDirectTls();
http.put_ProxyDirectTls(boolVal);

Introduced in version 9.5.0.83

Set to True if the proxy server expects a direct TLS connection. (This is where the initial connection to the HTTP proxy server is TLS. See Squid Direct TLS Connection. The default value of this property is False.

More Information and Examples

ProxyPort

# intVal is an integer
intVal = http.get_ProxyPort();
http.put_ProxyPort(intVal);

The port number of a proxy server if an HTTP proxy is used.

ReadTimeout

# intVal is an integer
intVal = http.get_ReadTimeout();
http.put_ReadTimeout(intVal);

The amount of time in seconds to wait before timing out when reading from an HTTP server. The ReadTimeout is the amount of time that needs to elapse while no additional data is forthcoming. During a long download, if the data stream halts for more than this amount, it will timeout. Otherwise, there is no limit on the length of time for the entire download.

The default value is 60 seconds. Note: Prior to v9.5.0.76, the default was 20 seconds.

ReceivedCertReq

# boolVal is a boolean
boolVal = http.get_ReceivedCertReq();

Introduced in version 9.5.0.92

Indicates whether the last HTTPS connection received a TLS CertificateRequest handshake message indicating that the server may require a client certificate.

RedirectVerb

# strVal is a string
# ckStr is a CkString
http.get_RedirectVerb(ckStr);
strVal = http.redirectVerb();
http.put_RedirectVerb(strVal);

Indicates the HTTP verb, such as GET, POST, PUT, etc. to be used for a redirect when the FollowRedirects property is set to True. The default value of this property is "GET". This will produce the same behavior as a web browser (such as FireFox). If this property is set to the empty string, then it will cause the same verb as the original HTTP request to be used.

Note: Prior to version 9.5.0.44, the default value of this property was the empty string.

Referer

# strVal is a string
# ckStr is a CkString
http.get_Referer(ckStr);
strVal = http.referer();
http.put_Referer(strVal);

The Referer header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is the empty string which causes the Referer field to be omitted from the request header.

RequiredContentType

# strVal is a string
# ckStr is a CkString
http.get_RequiredContentType(ckStr);
strVal = http.requiredContentType();
http.put_RequiredContentType(strVal);

If set, then any HTTP response to any POST or GET, including downloads, will be rejected if the content-type in the response header does not match this setting. If the content-type does not match, only the header of the HTTP response is read, the connection to the HTTP server is closed, and the remainder of the response is never read.

This property is empty (zero-length string) by default.

Some typical content-types are "text/html", "text/xml", "image/gif", "image/jpeg", "application/zip", "application/msword", "application/pdf", etc.

RequireSslCertVerify

# boolVal is a boolean
boolVal = http.get_RequireSslCertVerify();
http.put_RequireSslCertVerify(boolVal);

If True, then the HTTP client will verify the server's SSL certificate. The certificate is expired, or if the cert's signature is invalid, the connection is not allowed. The default value of this property is False.

More Information and Examples

Require that the Web Server's SSL Certificate is Non-Expired and the Signature is Valid

S3Ssl

# boolVal is a boolean
boolVal = http.get_S3Ssl();
http.put_S3Ssl(boolVal);

If True, then all S3_* methods will use a secure SSL/TLS connection for communications. The default value is True.

SaveCookies

# boolVal is a boolean
boolVal = http.get_SaveCookies();
http.put_SaveCookies(boolVal);

If this property is True, cookies are automatically persisted to XML files in the directory specified by the CookiesDir property (or in memory if CookieDir = "memory"). Both CookiesDir and SaveCookies must be set for cookies to be persisted.

More Information and Examples

Caching cookies in-memory.

SendBufferSize

# intVal is an integer
intVal = http.get_SendBufferSize();
http.put_SendBufferSize(intVal);

The buffer size to be used with the underlying TCP/IP socket for sending. The default value is 65535.

SendCookies

# boolVal is a boolean
boolVal = http.get_SendCookies();
http.put_SendCookies(boolVal);

If True, then cookies previously persisted to the CookiesDir are automatically added to all HTTP requests. Only cookies matching the domain and path are added.

More Information and Examples

Caching cookies in-memory.

SessionLogFilename

# strVal is a string
# ckStr is a CkString
http.get_SessionLogFilename(ckStr);
strVal = http.sessionLogFilename();
http.put_SessionLogFilename(strVal);

Enables file-based session logging. If set to a filename (or relative/absolute filepath), then the exact HTTP requests and responses are logged to a file. The file is created if it does not already exist, otherwise it is appended.

SniHostname

# strVal is a string
# ckStr is a CkString
http.get_SniHostname(ckStr);
strVal = http.sniHostname();
http.put_SniHostname(strVal);

Introduced in version 9.5.0.82

Specifies the SNI hostname to be used in the TLS ClientHello. This property is only needed when the domain is specified via a dotted IP address and an SNI hostname is desired. (Normally, Chilkat automatically uses the domain name in the SNI hostname TLS ClientHello extension.)

SocksHostname

# strVal is a string
# ckStr is a CkString
http.get_SocksHostname(ckStr);
strVal = http.socksHostname();
http.put_SocksHostname(strVal);

SocksPassword

# strVal is a string
# ckStr is a CkString
http.get_SocksPassword(ckStr);
strVal = http.socksPassword();
http.put_SocksPassword(strVal);

The SOCKS5 password (if required). The SOCKS4 protocol does not include the use of a password, so this does not apply to SOCKS4.

SocksPort

# intVal is an integer
intVal = http.get_SocksPort();
http.put_SocksPort(intVal);

The SOCKS4/SOCKS5 proxy port. The default value is 1080. This property only applies if a SOCKS proxy is used (if the SocksVersion property is set to 4 or 5).

SocksUsername

SslAllowedCiphers

# strVal is a string
# ckStr is a CkString
http.get_SslAllowedCiphers(ckStr);
strVal = http.sslAllowedCiphers();
http.put_SslAllowedCiphers(strVal);

Introduced in version 9.5.0.48

Provides a means for setting a list of ciphers that are allowed for SSL/TLS connections. The default (empty string) indicates that all implemented ciphers are possible. The TLS ciphers supported in Chilkat v9.5.0.55 and later are:

TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_ECDHE_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_MD5
TLS_DHE_RSA_WITH_DES_CBC_SHA
TLS_RSA_WITH_DES_CBC_SHA

To restrict SSL/TLS connections to one or more specific ciphers, set this property to a comma-separated list of ciphers such as "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384". The order should be in terms of preference, with the preferred algorithms listed first. (Note that the client cannot specifically choose the algorithm is picked because it is the server that chooses. The client simply provides the server with a list from which to choose.)

The property can also disallow connections with servers having certificates with RSA keys less than a certain size. By default, server certificates having RSA keys of 512 bits or greater are allowed. Add the keyword "rsa1024" to disallow connections with servers having keys smaller than 1024 bits. Add the keyword "rsa2048" to disallow connections with servers having keys smaller than 2048 bits.

Note: Prior to Chilkat v9.5.0.55, it was not possible to explicitly list allowed cipher suites. The deprecated means for indicating allowed ciphers was both incomplete and unprecise. For example, the following keywords could be listed to allow matching ciphers: "aes256-cbc", "aes128-cbc", "3des-cbc", and "rc4". These keywords will still be recognized, but programs should be updated to explicitly list the allowed ciphers.

secure-renegotiation: Starting in Chilkat v9.5.0.55, the keyword "secure-renegotiation" may be added to require that all renegotions be done securely (as per RFC 5746).

best-practices: Starting in Chilkat v9.5.0.55, this property may be set to the single keyword "best-practices". This will allow ciphers based on the current best practices. As new versions of Chilkat are released, the best practices may change. Changes will be noted here. The current best practices are:

If the server uses an RSA key, it must be 1024 bits or greater.
All renegotations must be secure renegotiations.
All ciphers using RC4, DES, or 3DES are disallowed.

Example: The following string would restrict to 2 specific cipher suites, require RSA keys to be 1024 bits or greater, and require secure renegotiations: "TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, rsa1024, secure-renegotiation"

SslProtocol

# strVal is a string
# ckStr is a CkString
http.get_SslProtocol(ckStr);
strVal = http.sslProtocol();
http.put_SslProtocol(strVal);

Introduced in version 9.5.0.46

Selects the SSL/TLS protocol version to be used for connections. Possible values are:

default
TLS 1.3
TLS 1.2
TLS 1.1
TLS 1.0
SSL 3.0
TLS 1.3 or higher
TLS 1.2 or higher
TLS 1.1 or higher
TLS 1.0 or higher

The default value is "default" which allows for the protocol to be selected dynamically at runtime based on the requirements of the server. Choosing an exact protocol will cause the connection to fail unless that exact protocol is negotiated. It is better to choose "X or higher" than an exact protocol. The "default" is effectively "SSL 3.0 or higher".

StreamResponseBodyPath

# strVal is a string
# ckStr is a CkString
http.get_StreamResponseBodyPath(ckStr);
strVal = http.streamResponseBodyPath();
http.put_StreamResponseBodyPath(strVal);

Introduced in version 9.5.0.49

Allows for the HTTP response body to be streamed directly into a file. If this property is set, then any method returning an HTTP response object will stream the response body directly to the file path specified. The HTTP response object will still contain the response header. (This property is useful when the HTTP response is too large to fit into memory.)

TlsCipherSuite

# strVal is a string
# ckStr is a CkString
http.get_TlsCipherSuite(ckStr);
strVal = http.tlsCipherSuite();

Introduced in version 9.5.0.49

Contains the current or last negotiated TLS cipher suite. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. A sample cipher suite string looks like this: TLS_DHE_RSA_WITH_AES_256_CBC_SHA256.

TlsPinSet

# strVal is a string
# ckStr is a CkString
http.get_TlsPinSet(ckStr);
strVal = http.tlsPinSet();
http.put_TlsPinSet(strVal);

Introduced in version 9.5.0.55

Specifies a set of pins for Public Key Pinning for TLS connections. This property lists the expected SPKI fingerprints for the server certificates. If the server's certificate (sent during the TLS handshake) does not match any of the SPKI fingerprints, then the TLS handshake is aborted and the connection fails. The format of this string property is as follows:

hash_algorithm, encoding, SPKI_fingerprint_1, SPKI_fingerprint_2, ...

For example, the following string specifies a single sha256 base64-encoded SPKI fingerprint:

"sha256, base64, lKg1SIqyhPSK19tlPbjl8s02yChsVTDklQpkMCHvsTE="

This example specifies two SPKI fingerprints:

"sha256, base64, 4t37LpnGmrMEAG8HEz9yIrnvJV2euVRwCLb9EH5WZyI=, 68b0G5iqMvWVWvUCjMuhLEyekM5729PadtnU5tdXZKs="

Any of the following hash algorithms are allowed:.sha1, sha256, sha384, sha512, md2, md5, haval, ripemd128, ripemd160,ripemd256, or ripemd320.

The following encodings are allowed: base64, hex, and any of the encodings indicated in the link below.

More Information and Examples

Encodings Supported by Chilkat HTTP Public Key Pinning

TlsVersion

# strVal is a string
# ckStr is a CkString
http.get_TlsVersion(ckStr);
strVal = http.tlsVersion();

Introduced in version 9.5.0.49

Contains the current or last negotiated TLS protocol version. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. Possible values are "SSL 3.0", "TLS 1.0", "TLS 1.1", "TLS 1.2", and "TLS 1.3".

UncommonOptions

# strVal is a string
# ckStr is a CkString
http.get_UncommonOptions(ckStr);
strVal = http.uncommonOptions();
http.put_UncommonOptions(strVal);

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty. Can be set to a list of the following comma separated keywords:

"QuickDisconnect" - Introduced in v9.5.0.77. In the call to CloseAllConnections, do not disconnect cleanly. Instead just disconnect as quickly as possible.
"ProtectFromVpn" - Introduced in v9.5.0.80. On Android systems, will bypass any VPN that may be installed or active.
"TlsNoClientRootCert" - Introduced in v9.5.0.82. Will exclude root CA certs from being included in the client certificate chain that is sent to the server for client-side authentication. This must be set prior to calling SetSslClientCert.
"AllowEmptyHeaders" - Introduced in v9.5.0.82. If present, an empty value string passed to SetHeaderField will cause the header to be added with an empty value. Otherwise, for historical purposes and backward compatibility, the header field is removed when an empty value string is passed.
"AnsiLogin" - Introduced in v9.5.0.87. For HTTP basic authentication, the login and password is sent using the utf-8 byte representation. Some servers expect the ANSI byte representation (typically Windows-1252). Use this keyword to send the login/password using ANSI.

UpdateCache

# boolVal is a boolean
boolVal = http.get_UpdateCache();
http.put_UpdateCache(boolVal);

Controls whether the cache is automatically updated with the responses from HTTP GET requests.

More Information and Examples

Fetch Web Pages from Local Cache

UseIEProxy

# boolVal is a boolean
boolVal = http.get_UseIEProxy();
http.put_UseIEProxy(boolVal);

If True, the proxy address/port used by Internet Explorer will also be used by Chilkat HTTP. Note: This property only pays attention to the proxy address and port, and does not pay attention to additional information such as IE proxy server exceptions.

UserAgent

# strVal is a string
# ckStr is a CkString
http.get_UserAgent(ckStr);
strVal = http.userAgent();
http.put_UserAgent(strVal);

This property, if set, is the value of the User-Agent header field to be automatically included with GET requests issued by QuickGet or QuickGetStr. The default value is the empty string and no User-Agent header field will be sent.

Utf8

# boolVal is a boolean
boolVal = http.get_Utf8();
http.put_Utf8(boolVal);

When set to True, all "const char *" arguments are interpreted as utf-8 strings. If set to False (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to True, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to False, all "const char *" return values are ANSI strings.

VerboseLogging

# boolVal is a boolean
boolVal = http.get_VerboseLogging();
http.put_VerboseLogging(boolVal);

If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Version

# strVal is a string
# ckStr is a CkString
http.get_Version(ckStr);
strVal = http.version();

Version of the component/library, such as "9.5.0.94"

More Information and Examples

How to get the Chilkat version at runtime.

WasRedirected

# boolVal is a boolean
boolVal = http.get_WasRedirected();

Indicates whether the last HTTP request was redirected (i.e. the redirect was automatically followed). If FollowRedirects is False and the response status code is 301, 302, 303, 307, or 308, then this property will remain False but the FinalRedirectUrl will contain the redirect URL that was not automatically followed.

Methods

AddCacheRoot

# dir is a string
http.AddCacheRoot(dir);

This method must be called at least once if disk caching is to be used. The file path (including drive letter) such as "E:\MyHttpCache\" is passed to AddCacheRoot to specify the root directory. The cache can be spread across multiple disk drives by calling AddCacheRoot multiple times, each with a directory path on a separate disk drive.

Fetch Web Pages from Local Cache

ClearHeaders

http.ClearHeaders();

Introduced in version 9.5.0.77

Removes all headers added via the SetRequestHeader method.

ClearInMemoryCookies

http.ClearInMemoryCookies();

Clears all cookies cached in memory. Calling this only makes sense if the CookieDir property is set to the string "memory".

ClearUrlVars

http.ClearUrlVars();

Introduced in version 9.5.0.67

Clears all URL variable values previously set by one or more calls to SetUrlVar.

CloseAllConnections

status = http.CloseAllConnections();

Closes all connections still open from previous HTTP requests.

An HTTP object instance will maintain up to 10 connections. If the HTTP server's response does not include a "Connection: Close" header, the connection will remain open and will be re-used if possible for the next HTTP request to the same hostname:port. (It uses the IP address (in string form) or the domain name, whichever is used in the URL provided by the application.) If 10 connections are already open and another is needed, the object will close the least recently used connection.

Returns True for success, False for failure.

CloseAllConnectionsAsync ⁽¹⁾

# returns a CkTask
ret_task = http.CloseAllConnectionsAsync();

Creates an asynchronous task to call the CloseAllConnections method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns None on failure

CreateOcspRequest

# requestDetails is a CkJsonObject
# ocspRequest is a CkBinData
status = http.CreateOcspRequest(requestDetails, ocspRequest);

Introduced in version 9.5.0.75

Creates an OCSP request for one or more certificates. The requestDetails is a JSON document describing the content of the OCSP request to be created. The examples in the links below show how to build the JSON request details.

Note: This method only creates an OCSP request. After creating, it may be sent to a server to get the OCSP response.

Returns True for success, False for failure.

CreateTimestampRequest

# hashAlg is a string
# hashVal is a string
# reqPolicyOid is a string
# addNonce is a boolean
# reqTsaCert is a boolean
# timestampToken is a CkBinData
status = http.CreateTimestampRequest(hashAlg, hashVal, reqPolicyOid, addNonce, reqTsaCert, timestampToken);

Introduced in version 9.5.0.75

Creates an RFC 3161 time-stamp request and returns the binary request token in timestampToken. The hashAlg can be "sha1", "sha256", "sha384", "sha512", or "md5", The hashVal is the base64 hash of the data to be timestamped. The optional reqPolicyOid is the requested policy OID in a format such as "1.3.6.1.4.1.47272.1.2". The addNonce indicates whether to auto-generate and include a nonce in the request. It may be True or False. The reqTsaCert determines whether or not to request the TSA's certificate (True = Yes, False = No).

Note: This method only creates a timestamp request. After creating, it may be sent to a server to get the binary timestamp token.

Returns True for success, False for failure.

DnsCacheClear

http.DnsCacheClear();

Introduced in version 9.5.0.38

Clears the Chilkat-wide in-memory hostname-to-IP address DNS cache. Chilkat automatically maintains this in-memory cache to prevent redundant DNS lookups. If the TTL on the DNS A records being accessed are short and/or these DNS records change frequently, then this method can be called clear the internal cache. Note: The DNS cache is used/shared among all Chilkat objects in a program, and clearing the cache affects all Chilkat objects.

PostXml

# returns a CkHttpResponse
# endpointUrl is a string
# xmlContent is a string
# xmlCharset is a string
ret_httpResponse = http.PostXml(endpointUrl, xmlContent, xmlCharset);

A simplified way of posting XML content to a web server. This method is good for making SOAP calls using HTTP POST. The xmlCharset should match the character encoding used in the xmlContent, which is typically "utf-8". The HTTP response is returned in an HTTP response object.

Important: This method sends the POST with a "Content-Type" header value of "application/xml". In rare cases, a server might require the Content-Type header to be "text/xml". To use "text/xml" instead of the default "application/xml", call SetRequestHeader("Content-Type","text/xml") prior to calling this method.

To use HTTPS simply pass an endpointUrl beginning with "https://" instead of "http://". This applies to any Chilkat method where a URL is passed as an argument.

PutBinary

# url is a string
# byteData is a CkByteData
# contentType is a string
# md5 is a boolean
# gzip is a boolean
# outStr is a CkString (output)
status = http.PutBinary(url, byteData, contentType, md5, gzip, outStr);
retStr = http.putBinary(url, byteData, contentType, md5, gzip);

Sends an HTTP PUT request to the url. The body of the HTTP request is byteData. The contentType is a content type such as "image/gif", "application/pdf", etc. If md5 is True, then a Content-MD5 header is added with the base64 MD5 hash of the byteData. Servers aware of the Content-MD5 header will perform a message integrity check to ensure that the data has not been corrupted. If gzip is True, the byteData is compressed using the gzip algorithm. The HTTP request body will contain the GZIP compressed data, and a "Content-Encoding: gzip" header is automatically added to indicate that the request data needs to be ungzipped when received (at the server).

Returns the text body of the HTTP response if the HTTP response has a success status code. Otherwise the method is considered to have failed. If more details of the HTTP response are required, call PBinary instead (which returns the HTTP response object).

Returns True for success, False for failure.

retStr = http.putText(url, textData, charset, contentType, md5, gzip);

Sends an HTTP PUT request to the url. The body of the HTTP request is textData. The charset should be set to a charset name such as "iso-8859-1", "windows-1252", "Shift_JIS", "utf-8", etc. The string "ansi" may also be used as a charset name. The contentType is a content type such as "text/plain", "text/xml", etc. If md5 is True, then a Content-MD5 header is added with the base64 MD5 hash of the textData. Servers aware of the Content-MD5 header will perform a message integrity check to ensure that the data has not been corrupted. If gzip is True, the textData is compressed using the gzip algorithm. The HTTP request body will contain the GZIP compressed data, and a "Content-Encoding: gzip" header is automatically added to indicate that the request data needs to be ungzipped when received (at the server).

# objectName is a string
status = http.S3_UploadBd(bd, contentType, bucketPath, objectName);

Introduced in version 9.5.0.76

The same as S3_UploadFile, except the contents of the file come from bd instead of a local file.

Note: x-amz-* headers, including metadata, can be added to any S3 request by adding each header with a call to SetRequestHeader. This applies to all S3 methods, even if not explicitly stated.

Note: If the bucket is in a region different than us-east-1, makes sure to set the AwsEndpoint property to the correct region, such as "eu-central-1". Also, if using an S3 compatible service such as Wasabi, always set the AwsEndpoint property. For example: "s3.wasabisys.com", "s3.eu-central-1.wasabisys.com".

Returns True for success, False for failure.

SetAuthTokenSb

# sb is a CkStringBuilder
status = http.SetAuthTokenSb(sb);

Introduced in version 9.5.0.95

Sets the AuthToken property. The sb contains the OAuth2 access token to be used.

Returns True for success, False for failure.

SetCookieXml

# domain is a string
# cookieXml is a string
status = http.SetCookieXml(domain, cookieXml);

Restores cookies for a particular domain. It is assumed that the cookie XML was previously retrieved via the GetCookieXml method, and saved to some sort of persistent storage, such as within a database table. It is then possible for an application to restore the cookies by calling this method.

Returns True for success, False for failure.

SetOAuthRsaKey

# privKey is a CkPrivateKey
status = http.SetOAuthRsaKey(privKey);

Introduced in version 9.5.0.39

Sets the RSA key to be used with OAuth authentication when the RSA-SHA1 OAuth signature method is used (see the OAuthSigMethod property).

Returns True for success, False for failure.

SetRequestHeader

# headerFieldName is a string
# headerFieldValue is a string
http.SetRequestHeader(headerFieldName, headerFieldValue);

Adds a custom header field to any HTTP request sent by a method that does not use the HTTP request object. These methods include Download, DownloadAppend, GetHead, PostBinary, PostXml, PutBinary, PutText, QuickDeleteStr, QuickGet, QuickGetObj, QuickGetStr, QuickPutStr, XmlRpc, and XmlRpcPut.

Cookies may be explictly added by calling this method passing "Cookie" for the headerFieldName.

The RemoveRequestHeader method can be called to remove a custom header.

Note1: Do not call this method to add Basic authentication, i.e. "Authorization: Basic ....". Instead, set the Login and Password properties, and also set the BasicAuth property = True. Chilkat will add the "Authorization: Basic ..." header using the correct format automatically.

Note 2: Never explicitly set the Content-Length header field. Chilkat will automatically compute the correct length and add the Content-Length header to all POST, PUT, or any other request where the Content-Length needs to be specified. (GET requests always have a 0 length body, and therefore never need a Content-Length header field.)

Note 3: To add more than one header, call this method once per header field.

Note 4:: Passing an empty value string causes the header to be removed. This was the unfortunate behavior of the method from the beginning, and cannot be changed for backward compatibility reasons. A workaround exists starting in v9.5.0.82 by adding the "AllowEmptyHeaders" keyword to the UncommonOptions property.

SetSecurePassword

# password is a CkSecureString
status = http.SetSecurePassword(password);

Introduced in version 9.5.0.76

Equivalent to setting the Password property, but provides for a more secure way of passing the password in a secure string object.

Returns True for success, False for failure.

SetSslCertRequirement

# reqName is a string
# reqValue is a string
status = http.SetSslCertRequirement(reqName, reqValue);

Introduced in version 9.5.0.84

Enforces a requirement on the server's certificate. The reqName can be one of the following:

SubjectDN
SubjectCN
IssuerDN
IssuerCN
SAN (added in v9.5.0.84)

The reqName specifies the part of the certificate, and the reqValue is the value that it must match exactly or with a wildcard (*). If the server's certificate does not match, the SSL / TLS connection is aborted.

Returns True for success, False for failure.

Returns True for success, False for failure.

SharePointOnlineAuth

# siteUrl is a string
# username is a string
# password is a CkSecureString
# extraInfo is a CkJsonObject
status = http.SharePointOnlineAuth(siteUrl, username, password, extraInfo);

Introduced in version 9.5.0.73

Authenticates with SharePoint Online, resulting in a cookie being set and used for subsequent SharePoint HTTP requests. Prior to calling this method, an application should set the CookieDir property to either "memory" or a directory path to persist the SharePoint authentication cookie to be automatically used in subsequent runs.

This method has the side-effect of setting the SaveCookies and SendCookies properties to True, because these settings are required for SharePoint Online authentication.

The siteUrl is a URL such as "https://yourdomain.sharepoint.com/". The username is an email address such as "username@yourdomain.com". The extraInfo is reserved for providing additional information as needed in the future.

Returns True for success, False for failure.

SynchronousRequest

# returns a CkHttpResponse
# domain is a string
# port is an integer
# ssl is a boolean
# req is a CkHttpRequest
ret_httpResponse = http.SynchronousRequest(domain, port, ssl, req);

Sends an explicit HttpRequest to an HTTP server and returns an HttpResponse object. The HttpResponse object provides full access to the response including all headers and the response body. This method may be used to send POST requests, as well as GET, HEAD, file uploads, and XMLHTTP. To send via HTTPS (i.e. TLS), set the ssl property = True. Otherwise set it to False.

NOTE: The 1st argument of this method is a domain, not a URL. For example, DO NOT pass "https://www.somedomain.com/" in the 1st argument. Instead, pass "www.somedomain.com".

VerifyTimestampReply

# timestampReply is a CkBinData
# tsaCert is a CkCert
retInt = http.VerifyTimestampReply(timestampReply, tsaCert);

Introduced in version 9.5.0.75

Verifies a timestamp reply received from a timestamp authority (TSA). Returns the following possible integer values:

-1: The timestampReply does not contain a valid timestamp reply.
-2: The timestampReply is a valid timestamp reply, but failed verification using the public key of the tsaCert.
0: Granted and verified.
1: Granted and verified, with mods (see RFC 3161)
2: Rejected.
3: Waiting.
4: Revocation Warning
5: Revocation Notification

If the timestamp reply (timestampReply) is known to be from a trusted source, then the tsaCert may be empty. If tsaCert is empty (never loaded with a certificate), then the verification will use the certificate embedded in the timestamp reply.
