Rest

If this property is set to False, then no MIME header folding will be automatically applied to any request header. The default is True. This property is provided to satisfy certain providers, such as Quickbooks, that require all MIME headers to be single unfolded lines regardless of length.

Controls whether non us-ascii HTTP request headers are automatically Q/B encoded. The default value is True.

Q/B encoded headers explicitly indicate the charset and byte representation, and appear as such: =?utf-8?Q?...?= or =?utf-8?B?...?=, where the charset may be "utf-8" or any other possible charset.

If this property is set to False, then no Q/B encoding is applied to any request header.

The value of the Authorization HTTP request header (if needed).

See the notes about PWideChar memory ownership and validity.

If the Connect method fails, this property can be checked to determine the reason for failure.

Possible values are:

0 = success

Normal (non-SSL) 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)
99 = Chilkat not unlocked / trial expired.

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.
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.

The maximum amount of time to wait for the connection to be accepted by the HTTP server.

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:

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

See the notes about PWideChar memory ownership and validity.

If True then all calls to Send* or FullRequest* methods will not actually send a request. Instead, the request will be written to a memory buffer which can then be retrieved by calling GetLastDebugRequest.

This property is only valid in programming environment and languages that allow for event callbacks.

Specifies the time interval in milliseconds between AbortCheck events. A value of 0 (the default) indicate that no AbortCheck events will fire. Any REST method can be aborted via the AbortCheck event.

The value of the Host HTTP request header.

See the notes about PWideChar memory ownership and validity.

The maximum amount of time to wait for additional incoming data when receiving, or the max time to wait to send additional data. The default value is 30000 (30 seconds). This is not an overall max timeout. Rather, it is the maximum time to wait when receiving or sending has halted.

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.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

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.

The full MIME header (not including the HTTP start line which contains the status code and status text), of the last request sent.

See the notes about PWideChar memory ownership and validity.

The full start line of the last request sent. (The start line begins with the HTTP verb, such as GET, POST, etc., is followed by the URI path, and ends with the HTTP version.)

See the notes about PWideChar memory ownership and validity.

The number of response header fields. The first response header field is at index 0.

Only used for multipart requests. Selects the target MIME part for calls to AddHeader, RemoveHeader, SetMultipartBodyBinary, SetMultipartBodyString, SetMultipartBodyStream, etc. The default is an empty string and indicates the top-level header. A string value of "1" would indicate the 1st sub-part in a multipart request. A string value of "1.2" would indicate the 2nd sub-part under the 1st sub-part.

It is unlikely you'll ever encounter the need for nested multipart requests (i.e. part selectors such as "1.2") Also, most REST requests are NOT multipart, and therefore this feature is rarely used. An example of a multipart REST request would be for a Google Drive upload, where the top-level Content-Type is multipart/related, the1st sub-part contains the JSON meta-data, and the 2nd sub-part contains the file data.

See the notes about PWideChar memory ownership and validity.

This property only applies to the FullRequest* methods, which are methods that both send an HTTP request and receive the response. (It also only applies to programming languages that support event callbacks.) It determines whether percentage completion is tracked for the sending of the HTTP request, or for the downloading the HTTP response. The default value is False, which is to measure the percent completion when receiving the response.

For example: If the REST request is to download a file, then this property should remain at the default value of False. If the REST request is to upload a file (using a Full* method), then set this property to True. Also note if a server sends an HTTP response in the chunked encoding, it is not possible to measure percent completion because the HTTP client has no way of knowing the total size of the HTTP response.

The full response MIME header (not including the HTTP start line which contains the status code and status text).

See the notes about PWideChar memory ownership and validity.

The response status code.

The status message corresponding to the response status code.

See the notes about PWideChar memory ownership and validity.

If True, then methods that upload data are sent non-chunked if possible. For example, if the FullRequestStream method is called where the stream is a file stream, then the size of the content is known and the HTTP request will be sent using a Content-Length header instead of using a Transfer-Encoding: chunked upload. If False, then the chunked transfer encoding is used. The default value of this property is True.

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:

• AllowDuplicateQueryParams - Affects the AddQueryParam method. If the query parameter to be added already exists, it is not replaced and instead an additional param with the same name is added.
• AllowInsecureBasicAuth - Introduced in v9.5.0.80. Allows HTTP Basic authentication over non-TLS connections. (HTTP Basic authentication puts the login:password in the Authorization header field in base64 encoding. If transmitted over an insecure connection, it is potentially visible to anything sniffing the traffic. By default, Chilkat disallows HTTP Basic authentication except for SSL/TLS connections, SSH tunneled connections, or connections to localhost.)
• DisableTls13 Disables TLS 1.3 so that only TLS 1.2 or lower is used.
• ProtectFromVpn - Introduced in v9.5.0.80. On Android systems, will bypass any VPN that may be installed or active.

See the notes about PWideChar memory ownership and validity.

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 of the component/library, such as "9.5.0.94"

See the notes about PWideChar memory ownership and validity.

Adds an HTTP request header. If the header field already exists, then it is replaced.

Returns True for success, False for failure.

Computes the Amazon MWS signature using the mwsSecretKey and adds the "Signature" parameter to the request. This method should be called for all Amazon Marketplace Web Service (Amazon MWS) HTTP requests. It should be called after all request parameters have been added.

Important: The Chilkat v9.5.0.75 release accidentally breaks Amazon MWS (not AWS) authentication. If you need MWS with 9.5.0.75, send email to support@chilkatsoft.com for a hotfix, or revert back to v9.5.0.73, or update to a version after 9.5.0.75.

The domain should be the domain of the request, such as one of the following:

• mws.amazonservices.com
• mws-eu.amazonservices.com
• mws.amazonservices.in
• mws.amazonservices.com.cn
• mws.amazonservices.jp

The httpVerb should be the HTTP verb, such as "GET", "POST", etc. The uriPath is the URI path, such as "/Feeds/2009-01-01". In general, the httpVerb and uriPath should be identical to the 1st two args passed to methods such as FullRequestFormUrlEncoded.

Note: This method also automatically adds or replaces the existing Timestamp parameter to the current system date/time.

Returns True for success, False for failure.

Adds or replaces a path parameter. A path parameter is a string that will be replaced in any uriPath string passed to a method. For example, if name is "fileId" and value is "1R_70heIyzIAu1_u0prXbYcaIiJRVkgBl", then a uriPath argument of "/drive/v3/files/fileId" will be transformed to "/drive/v3/files/1R_70heIyzIAu1_u0prXbYcaIiJRVkgBl" in a method call.

Returns True for success, False for failure.

Adds a query parameter. If the query parameter already exists, then it is replaced.

To allow duplicates, you can add the keyword "AllowDuplicateQueryParams" to the UncommonOptions property value. In other words, if the query parameter already exists, it is not replaced and instead an additional param with the same name is added.

Returns True for success, False for failure.

Adds the query parameters from the queryString. The queryString is a query string of the format field1=value1&field2=value2&field3=value3... where each value is URL encoded.

Returns True for success, False for failure.

Adds a query parameter. If the query parameter already exists, then it is replaced. The parameter value is passed in a StringBuilder object.

Returns True for success, False for failure.

Removes all HTTP request headers.

Returns True for success, False for failure.

Removes all sub-parts from a request. This is useful when preparing the REST object to send a new request after a multipart request has just been sent.

Returns True for success, False for failure.

Clears all path parameters.

Returns True for success, False for failure.

Clears all query parameters.

Returns True for success, False for failure.

Clears all authentication settings.

Returns True for success, False for failure.

Clears the response body stream.

Establishes an initial connection to a REST server. The hostname can be a domain name or an IP address. Both IPv4 and IPv6 addresses are supported. The port is the port, which is typically 80 or 443. If SSL/TLS is required, then tls should be set to True. The autoReconnect indicates whether connection should automatically be established as needed for subsequent REST requests.

Note: This method is for simple connections that do not require any proxies (HTTP or SOCKS), or SSH tunneling. If a proxy, SSH tunnel, or any other advanced socket feature is required, the Chilkat Socket API can be used to establish the connection. The UseConnection method can then be called to use the pre-established socket connection.

IMPORTANT: The hostname argument should be just the domain or IP address. It is NOT the full URL. If your URL is "https://www.example.com/something/123", then pass "www.example.com" in the 1st argument.

Returns True for success, False for failure.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns nil on failure

Closes the connection with the HTTP server if one is open. This method can be called to ensure the connection is closed. The maxWaitMs is the maximum time in milliseconds to wait for a clean close. If the connection is through an SSH tunnel, this closes the logical channel within the SSH tunnel, and not the connection with the SSH server itself.

Returns True for success, False for failure.

Sends a multipart REST request. The httpVerb is the HTTP verb (also known as the HTTP method), such as "GET". The uriPath is the path of the resource URI.

IMPORTANT: The uriPath argument should be just the path part of the URL. It is NOT the full URL. If your URL is "https://www.example.com/something/123?xyz=1", then the uriPath is "/something/123?xyz=1".

Returns True for success, False for failure.

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

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns nil on failure

Sends a REST request that cotnains no body. The httpVerb is the HTTP verb (also known as the HTTP method), such as "GET". The uriPath is the path of the resource URI.

IMPORTANT: The uriPath argument should be just the path part of the URL. It is NOT the full URL. If your URL is "https://www.example.com/something/123?xyz=1", then the uriPath is "/something/123?xyz=1".

Returns True for success, False for failure.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns nil on failure

Sends a REST request that cotnains a text body, such as XML or JSON. The httpVerb is the HTTP verb (also known as the HTTP method), such as "PUT". The uriPath is the path of the resource URI. The bodySb contains the text of the HTTP request body.

IMPORTANT: The uriPath argument should be just the path part of the URL. It is NOT the full URL. If your URL is "https://www.example.com/something/123?xyz=1", then the uriPath is "/something/123?xyz=1".

Returns True for success, False for failure.

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

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns nil on failure

Sends a REST request that cotnains a binary or text body that is obtained by reading from the stream. The httpVerb is the HTTP verb (also known as the HTTP method), such as "PUT". The uriPath is the path of the resource URI.

IMPORTANT: The uriPath argument should be just the path part of the URL. It is NOT the full URL. If your URL is "https://www.example.com/something/123?xyz=1", then the uriPath is "/something/123?xyz=1".

Returns True for success, False for failure.

Returns nil on failure

Sets the authorization service provider for Amazon AWS REST requests. An application that sets an AWS authentication provider need not explicitly set the Authorization property. Each REST request is automatically signed and authenticated using the authProvider.

Returns True for success, False for failure.

Provides the information for Azure SAS (Shared Access Signature) authorization. Calling this method will cause the "Authorization: SharedAccessSignature ..." header to be automatically added to all requests.

Returns True for success, False for failure.

Sets the authorization service provider for Azure Storage Service requests.

Returns True for success, False for failure.

Sets the username and password to be used for Basic authentication. This method should be called when Basic authentication is required. It should only be used with secure SSL/TLS connections. Calling this method will cause the "Authorization: Basic ..." header to be automatically added to all requests. In many cases, a REST API will support Basic authentication where the username is a client ID or account ID, and the password is a client secret or token.

Returns True for success, False for failure.

The same as SetAuthBasic, but provides a more secure means for passing the arguments as secure string objects.

Returns True for success, False for failure.

Sets the authorization service provider for Google API requests.

Returns True for success, False for failure.

Sets the authentication provider for REST API requests needing OAuth 1.0 (and OAuth 1.0a) authentication. If useQueryParams is True, then the OAuth1 authentication information and signature is passed in query parameters. Otherwise it is passed in an Authorization header.

Returns True for success, False for failure.

Causes the "Authorization: Bearer <access_token>" header to be added to each request. The authProvider should have been loaded with an OAuth2 access token, which is JSON that looks similar to this:

{
  "access_token": "...",
  "refresh_token": "...",
  "expires_in": 14400,
  "scope": "...",
  "token_type": "bearer",
  "expires_on": "1611099058"
}

Your access token may contain different JSON members, but it should contain the two required members "access_token" and "token_type". The "token_type" should be "bearer" (case-insensitive).

Note: It is also possible to manually add the Authorization header in the same way as any other header by calling the AddHeader method. If the Authorization header is added via AddHeader, then don't use this method.

Returns True for success, False for failure.

Only used for multipart requests. Sets the binary content of the multipart body indicated by the PartSelector.

Returns True for success, False for failure.

Only used for multipart requests. Sets the binary content of the multipart body indicated by the PartSelector.

Returns True for success, False for failure.

Only used for multipart requests. Sets the text content of the multipart body indicated by the PartSelector.

Returns True for success, False for failure.

Only used for multipart requests. Sets the stream source of the multipart body indicated by the PartSelector.

Returns True for success, False for failure.

Only used for multipart requests. Sets the text content of the multipart body indicated by the PartSelector.

Returns True for success, False for failure.

Only applies to the Full* methods, such as FullRequestNoBody, FullRequestBinary, FullRequestStream, etc. When set, the response body is streamed directly to responseStream, if (and only if) the HTTP response status code equals expectedStatus.

If the response body was streamed to responseStream, then the string return value of the Full* method instead becomes "OK" for success. If an attempt was made to stream the response body but it failed, then "FAIL" is returned. If the response body was not streamed because the response status code was not equal to expectedStatus, then the returned string contains the server's error response.

If autoSetStreamCharset is True, then the expectedStatus's StringCharset property will automatically get set based on the charset, if any, indicated in the response header. If the response is binary, then autoSetStreamCharset is ignored.

Starting in v9.5.0.75, the expectedStatus may be passed as a negative number to specify a range of expected (success) status codes. For example:

• -200: Allow status codes 200 - 299
• -210: Allow status codes 210 - 219
• -220: Allow status codes 220 - 229
• etc.

Returns True for success, False for failure.

Sets the connection to be used for sending the REST request. The connection should be an already-connected socket. It may be a TLS connection, an unencrypted connection, through an HTTP proxy, a SOCKS proxy, or even through SSH tunnels. All of the connection related functionality is handled by the Chilkat Socket API.

The autoReconnect indicates whether connection should automatically be established as needed for subsequent REST requests.

Important: The UseConnection method is provided as a means for handling more complicated connections -- such as connections through proxies, tunnels, etc. If your application is connecting directly to the HTTP server, then simply call this class's Connect method.

Returns True for success, False for failure.

Provides the opportunity for a method call to be aborted. The AbortCheck event is fired periodically based on the value of the HeartbeatMs property. If HeartbeatMs is 0, then no AbortCheck events will fire. As an example, to fire 5 AbortCheck events per second, set the HeartbeatMs property equal to 200. Return True to abort; return False to continue (not abort)

Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This event is only fired when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For operations (Chilkat method calls) that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).

The PercentDone callback counts as an AbortCheck event. For method calls that complete quickly such that PercentDone events fire, it may be that AbortCheck events don't fire because the opportunity to abort is already provided in the PercentDone callback. For time consuming operations, where the amount of time between PercentDone callbacks are long, AbortCheck callbacks may be used to allow for the operation to be aborted in a more responsive manner.

Return True to abort; return False to continue (not abort)

A general name/value event that provides information about what is happening during a method call. To find out what information is available, write code to handle this event and log the name/value pairs. Most are self-explanatory.

Called in the background thread when an asynchronous task completes.
