CkHttpRequest Perl Reference Documentation

CkHttpRequest

Current Version: 9.5.0.72

Represents a complete HTTP request.

Object Creation

$obj = chilkat::CkHttpRequest()->new();

Properties

Boundary
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_Boundary($ckStr);
$strVal = $httpRequest->boundary();
$httpRequest->put_Boundary($strVal);
Introduced in version 9.5.0.49

Sets an explicit boundary string to be used in multipart/form-data requests. If no Boundary is set, then a boundary string is automaticaly generated as needed during the sending of a request.

More Information and Examples
top
Charset
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_Charset($ckStr);
$strVal = $httpRequest->charset();
$httpRequest->put_Charset($strVal);

Controls the character encoding used for HTTP request parameters for POST requests. The default value is the ANSI charset of the computer. The charset should match the charset expected by the form target.

The "charset" attribute is only included in the Content-Type header of the request if the SendCharset property is set to 1.

top
ContentType
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_ContentType($ckStr);
$strVal = $httpRequest->contentType();
$httpRequest->put_ContentType($strVal);

The ContentType property sets the "Content-Type" header field, and identifies the content-type of the HTTP request body. Common values are:

application/x-www-form-urlencoded
multipart/form-data
text/xml
application/jsonrequest
If ContentType is set equal to the empty string, then no Content-Type header is included in the HTTP request.

top
DebugLogFilePath
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_DebugLogFilePath($ckStr);
$strVal = $httpRequest->debugLogFilePath();
$httpRequest->put_DebugLogFilePath($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:

  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.

top
EntireHeader
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_EntireHeader($ckStr);
$strVal = $httpRequest->entireHeader();
$httpRequest->put_EntireHeader($strVal);

Composes and returns the entire MIME header of the HTTP request.

top
HttpVerb
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_HttpVerb($ckStr);
$strVal = $httpRequest->httpVerb();
$httpRequest->put_HttpVerb($strVal);

The HttpVerb property should be set to the name of the HTTP method that appears on the "start line" of an HTTP request, such as GET, POST, PUT, DELETE, etc. It is also possible to use the various WebDav verbs such as PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, UNLOCK, etc. In general, the HttpVerb may be set to anything, even custom verbs recognized by a custom server-side app.

top
HttpVersion
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_HttpVersion($ckStr);
$strVal = $httpRequest->httpVersion();
$httpRequest->put_HttpVersion($strVal);

The HTTP version in the request header. Defaults to "1.1".

top
LastErrorHtml
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_LastErrorHtml($ckStr);
$strVal = $httpRequest->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.

top
LastErrorText
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_LastErrorText($ckStr);
$strVal = $httpRequest->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.

top
LastErrorXml
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_LastErrorXml($ckStr);
$strVal = $httpRequest->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.

top
LastMethodSuccess
# $boolVal is a boolean
$boolVal = $httpRequest->get_LastMethodSuccess();
$httpRequest->put_LastMethodSuccess($boolVal);
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 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 = 1 and failure = 0.
  • 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 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
NumHeaderFields
# $intVal is an integer
$intVal = $httpRequest->get_NumHeaderFields();

Returns the number of request header fields.

top
NumParams
# $intVal is an integer
$intVal = $httpRequest->get_NumParams();

Returns the number of query parameters.

More Information and Examples
top
Path
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_Path($ckStr);
$strVal = $httpRequest->path();
$httpRequest->put_Path($strVal);

The path of the resource requested. A path of "/" indicates the default document for a domain.

More Information and Examples
top
SendCharset
# $boolVal is a boolean
$boolVal = $httpRequest->get_SendCharset();
$httpRequest->put_SendCharset($boolVal);

Controls whether the charset is explicitly included in the content-type header field of the HTTP POST request. The default value of this property is 0.

top
Utf8
# $boolVal is a boolean
$boolVal = $httpRequest->get_Utf8();
$httpRequest->put_Utf8($boolVal);

When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.

top
VerboseLogging
# $boolVal is a boolean
$boolVal = $httpRequest->get_VerboseLogging();
$httpRequest->put_VerboseLogging($boolVal);

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
# $strVal is a string
# $ckStr is a CkString
$httpRequest->get_Version($ckStr);
$strVal = $httpRequest->version();

Version of the component/library, such as "9.5.0.63"

Methods

AddBytesForUpload
# $name is a string
# $remoteFileName is a string
# $byteData is a CkByteData
$status = $httpRequest->AddBytesForUpload($name, $remoteFileName, $byteData);

Adds a file to an upload request where the contents of the file come from an in-memory byte array. To create a file upload request, call UseUpload and then call AddBytesForUpload, AddStringForUpload, or AddFileForUpload for each file to be uploaded.

name is an arbitrary name. (In HTML, it is the form field name of the input tag.)
remoteFileName is the name of the file to be created on the HTTP server.
byteData contains the contents (bytes) to be uploaded.

Returns 1 for success, 0 for failure.

top
AddBytesForUpload2
# $name is a string
# $remoteFileName is a string
# $byteData is a CkByteData
# $contentType is a string
$status = $httpRequest->AddBytesForUpload2($name, $remoteFileName, $byteData, $contentType);

Same as AddBytesForUpload, but allows the Content-Type header field to be directly specified. (Otherwise, the Content-Type header is automatically determined based on the remoteFileName's file extension.)

Returns 1 for success, 0 for failure.

top
AddFileForUpload
# $name is a string
# $filePath is a string
$status = $httpRequest->AddFileForUpload($name, $filePath);

Adds a file to an upload request. To create a file upload request, call UseUpload and then call AddFileForUpload, AddBytesForUpload, or AddStringForUpload for each file to be uploaded. This method does not read the file into memory. When the upload occurs, the data is streamed directly from the file, thus allowing for very large files to be uploaded without consuming large amounts of memory.

name is an arbitrary name. (In HTML, it is the form field name of the input tag.)
filePath is the path to an existing file in the local filesystem.

Returns 1 for success, 0 for failure.

More Information and Examples
top
AddFileForUpload2
# $name is a string
# $filePath is a string
# $contentType is a string
$status = $httpRequest->AddFileForUpload2($name, $filePath, $contentType);

Same as AddFileForUpload, but allows the Content-Type header field to be directly specified. (Otherwise, the Content-Type header is automatically determined based on the file extension.)

name is an arbitrary name. (In HTML, it is the form field name of the input tag.)
filePath is the path to an existing file in the local filesystem.

Returns 1 for success, 0 for failure.

More Information and Examples
top
AddHeader
# $name is a string
# $value is a string
$httpRequest->AddHeader($name, $value);

Adds a request header to the HTTP request. If a header having the same field name is already present, this method replaces it.

Note: 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.)

More Information and Examples
top
AddMwsSignature
# $domain is a string
# $mwsSecretKey is a string
$status = $httpRequest->AddMwsSignature($domain, $mwsSecretKey);
Introduced in version 9.5.0.66

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.

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

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

Returns 1 for success, 0 for failure.

top
AddParam
# $name is a string
# $value is a string
$httpRequest->AddParam($name, $value);

Adds a request query parameter (name/value pair) to the HTTP request. The name and value strings passed to this method should not be URL encoded.

top
AddStringForUpload
# $name is a string
# $filename is a string
# $strData is a string
# $charset is a string
$status = $httpRequest->AddStringForUpload($name, $filename, $strData, $charset);

Same as AddFileForUpload, but the upload data comes from an in-memory string instead of a file.

Returns 1 for success, 0 for failure.

top
AddStringForUpload2
# $name is a string
# $filename is a string
# $strData is a string
# $charset is a string
# $contentType is a string
$status = $httpRequest->AddStringForUpload2($name, $filename, $strData, $charset, $contentType);

Same as AddStringForUpload, but allows the Content-Type header field to be directly specified. (Otherwise, the Content-Type header is automatically determined based on the filename's file extension.)

Returns 1 for success, 0 for failure.

top
AddSubHeader
# $index is an integer
# $name is a string
# $value is a string
$status = $httpRequest->AddSubHeader($index, $name, $value);
Introduced in version 9.5.0.55

Returns 1 for success, 0 for failure.

More Information and Examples
top
LoadBodyFromString
# $bodyStr is a string
# $charset is a string
$status = $httpRequest->LoadBodyFromString($bodyStr, $charset);

The HTTP protocol is such that all HTTP requests are MIME. For non-multipart requests, this method may be called to set the MIME body of the HTTP request to the exact contents of bodyStr.
Note: A non-multipart HTTP request consists of (1) the HTTP start line, (2) MIME header fields, and (3) the MIME body. This method sets the MIME body.

charset indicates the charset, such as "utf-8" or "iso-8859-1", to be used. The HTTP body will contain the bodyStr converted to this character encoding.

More Information and Examples
top
StreamBodyFromFile
# $filePath is a string
$status = $httpRequest->StreamBodyFromFile($filePath);

Useful for sending HTTP requests where the body is a very large file. For example, to send an XML HttpRequest containing a very large XML document, one would set the HttpVerb = "POST", the ContentType = "text/xml", and then call StreamBodyFromFile to indicate that the XML body of the request is to be streamed directly from a file. When the HTTP request is actually sent, the body is streamed directly from the file, and thus the file never needs to be loaded in its entirety in memory.

Returns 1 for success, 0 for failure.

More Information and Examples
top
StreamChunkFromFile
# $path is a string
# $offset is a string
# $numBytes is a string
$status = $httpRequest->StreamChunkFromFile($path, $offset, $numBytes);
