Chilkat.HttpResponse
Read the HTTP status code, status line, and related response information
to determine whether the request succeeded, redirected, or failed.
Inspect response headers, retrieve individual header values, and access
cookies returned by the server.
Get the response body as raw bytes or decoded text, using the response
charset information when appropriate.
Load the body directly into
Access redirect-related information such as the redirect URL when the
server responds with a redirect status.
Save body content, inspect the full MIME-style response, and use response
metadata for diagnostics, logging, or API troubleshooting.
For an extended overview, see
HttpResponse Class Overview.
Inspect HTTP status, headers, cookies, redirects, and response bodies.
Chilkat.HttpResponse represents an HTTP response returned by
certain Chilkat.Http methods. It provides access to the response
status line, status code, headers, cookies, charset, content length, body
bytes, body text, full MIME response, redirect URL, and helper methods for
saving or loading the response body into Chilkat objects such as
BinData, StringBuilder, JsonObject,
JsonArray, and Xml.
Status and reason
Headers and cookies
Body as text or bytes
Structured body loading
JsonObject,
JsonArray, Xml, BinData, or
StringBuilder objects for further processing.
Redirect information
Save and inspect responses
Chilkat.Http, check the
StatusCode, inspect headers or cookies as needed, then retrieve
the body in the form best suited to the response content: text, bytes,
BinData, StringBuilder, JSON, or XML. Use
HttpResponse for response inspection; use Chilkat.Http
for the actual network request.
Object Creation
use Chilkat2\HttpResponse;
try {
$httpResponse = new HttpResponse();
// ... use $httpResponse ...
} catch (\Chilkat2\Exception $e) {
echo $e->getClass(), '::', $e->getMethod(), " failed\n";
echo $e->getMessage(), "\n"; // the LastErrorText of the failed call
}Creates the object. The optional array sets properties in order, as if assigned one by one (new HttpResponse(['VerboseLogging' => true, 'RaiseError' => false])); an unknown or read-only name throws Error. The class is defined by the chilkat2 extension (extension=chilkat2 in php.ini): there is no PHP file to include.
There is no close(): PHP frees the object when its last reference goes (unset($httpResponse), $httpResponse = null, or the end of the function or request). Objects returned by methods are independent and freed the same way. The class may be extended (class MyHttpResponse extends \Chilkat2\HttpResponse); objects cannot be cloned or serialized.
When true (the default), a method that fails throws Chilkat2\Exception. When false, it returns false (or null) instead, and the reason is in LastErrorText. Objects returned by a method inherit the value of the object that returned them.
Errors
Chilkat2\Exception extends RuntimeException: getMessage() is the failed call's full LastErrorText, getClass() its class ('Chilkat2\HttpResponse') and getMethod() the method name. The object remains usable. Methods that look something up and find nothing return null without throwing (each such method says so), methods that answer a question (HasMember, IsUnlocked, ...) return a plain bool, and property reads and writes do not throw for Chilkat reasons.
Misuse always throws, whatever RaiseError is: a wrong argument type is a TypeError (exact types under declare(strict_types=1)), a missing or extra argument an ArgumentCountError, a string containing a NUL byte or an out-of-range integer a ValueError, and an unknown property (properties are case-sensitive) or a write to a read-only one an Error. Named arguments work with the parameter names shown.
Strings are passed and returned as UTF-8; binary data is a PHP string of bytes. Unlocking: call (new \Chilkat2\GlobalSettings())->UnlockBundle('...') once at startup.
Properties
BodyQP
The same as the Body property, but returned as a quoted-printable encoded string.
topBodyStr
The response body returned as a string.
topCharset
The response charset, such as iso-8859-1, if applicable. Obviously, responses for GIF and JPG files will not have a charset.
ContentLength
The content length of the response, in bytes.
topContentLength64
The content length of the response, in number of bytes, returned as a 64-bit integer.
topDateStr
Returns the content of the Date response header field in RFC822 date/time string format.
topDebugLogFilePath
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
Domain
The domain of the HTTP server that created this response.
topFinalRedirectUrl
Returns the redirect URL for 301/302 responses.
topFullMime
Header
The full text of the response header.
topLastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
NumCookies
The number of cookies included in the response.
topNumHeaderFields
The number of response header fields.
topStatusCode
The status code (as an integer) from the first line of an HTTP response. If the StatusLine = HTTP/1.0 200 OK, the response status code returned is 200.
StatusLine
The first line of an HTTP response, such as HTTP/1.0 200 OK.
StatusText
The text that follows the status code in the 1st line of the HTTP response. For example, i the first line of an HTTP response is HTTP/1.0 200 OK, then this property contains OK.
UncommonOptions
This is a catch-all property to be used for uncommon needs. Can be set to a list of the following comma separated keywords:
TakeResponseBody- Introduced in v9.5.0.89. The GetBody* methods will transfer the body to the target object instead of copying the contents. This can be useful if the response body is extremely large because it will reduce the overall memory requirement.
VerboseLogging
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.
