Chilkat.HttpRequest

Build structured HTTP requests for use with Chilkat.Http.

Chilkat.HttpRequest is a helper class for constructing HTTP requests that are sent by Chilkat.Http. It does not perform network communication on its own. Instead, it provides structured control over the request method, HTTP version, path, headers, query parameters, form parameters, content type, request body, multipart uploads, streamed file bodies, and diagnostic request generation.

Request construction

Build an HTTP request object with the method, path, version, headers, parameters, and body settings required by the target endpoint.

Form parameters

Add name/value parameters for form posts and API requests that expect structured form data.

Custom headers

Set request headers such as content type, accept headers, authorization headers, or application-specific metadata.

Request bodies

Provide body content for POST, PUT, PATCH, or other methods that send data to a server.

Multipart and file uploads

Construct multipart/form-data requests, attach file parts, or stream a file as the request body when the API requires upload content.

Diagnostics

Generate a textual representation of the request to inspect headers, paths, parameters, body structure, and upload formatting before sending.

Common pattern: Create a HttpRequest, set the HTTP method and path, add any headers, parameters, body data, or file parts, then pass the request object to the appropriate Chilkat.Http method for sending. Use HttpRequest for structured or multipart requests; use simpler Http methods directly when only a basic GET, POST, upload, or download is needed.

Object Creation

use Chilkat2\HttpRequest;

try {
    $httpRequest = new HttpRequest();
    // ... use $httpRequest ...
} catch (\Chilkat2\Exception $e) {
    echo $e->getClass(), '::', $e->getMethod(), " failed\n";
    echo $e->getMessage(), "\n";              // the LastErrorText of the failed call
}
public function __construct(array $properties = [])

Creates the object. The optional array sets properties in order, as if assigned one by one (new HttpRequest(['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($httpRequest), $httpRequest = 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 MyHttpRequest extends \Chilkat2\HttpRequest); objects cannot be cloned or serialized.

public bool $RaiseError;

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\HttpRequest') 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

Boundary
public string $Boundary;
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
public string $Charset;

Controls the character encoding used in the URL encoding of query params. The default value of this propoerty is utf-8.

top
ContentType
public string $ContentType;

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
application/json
application/xml
If ContentType is set equal to the empty string, then no Content-Type header is included in the HTTP request.

top
DebugLogFilePath
public string $DebugLogFilePath;

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.

More Information and Examples
top
EntireHeader
public string $EntireHeader;

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

top
HttpVerb
public string $HttpVerb;

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
public string $HttpVersion;

The HTTP version in the request header. Defaults to 1.1. Can only be set to 1.0 or 1.1.

top
LastErrorHtml
public readonly string $LastErrorHtml;

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.

top
LastErrorText
public readonly string $LastErrorText;

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.

top
LastErrorXml
public readonly string $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.

top
LastMethodSuccess
public bool $LastMethodSuccess;

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.

top
NumHeaderFields
public readonly int $NumHeaderFields;

Returns the number of request header fields.

top
NumParams
public readonly int $NumParams;

Returns the number of query parameters.

More Information and Examples
top
Path
public string $Path;

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

Explaining the Parts of a URL

http://example.com:8042/over/there?name=ferret#nose
\__/   \______________/\_________/ \________/ \__/
 |           |            |            |        |
scheme   domain+port     path        query   fragment

This property should be set to the path part of the URL. You may also include the query part in this property value. If the Content-Type of the request is NOT application/x-www-form-urlencoded, then you would definitely want to include query parameters in the path. If the Content-Type of the request IS application/x-www-form-urlencoded, the query parameters are passed in the body of the request. It is also possible to pass some query parameters via the path, and some in the body of a application/x-www-form-urlencoded request, but you shouldn't include the same parameter in both places. You would never need to include the fragment part. The fragment is nothing more than an instruction for a browser to automatically navigate to a particular location in the HTML page (assuming the request returns HTML, otherwise a fragment makes no sense).

More Information and Examples
top
SendCharset
public bool $SendCharset;

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 false.

top
VerboseLogging
public bool $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.

top
Version
public readonly string $Version;

Version of the component/library, such as "10.1.0"

Methods

AddBdForUpload
public function AddBdForUpload(string $name, string $remoteFilename, BinData $byteData, string $contentType): bool
Introduced in version 9.5.0.76

Adds a file to an upload request where the contents of the file come from $byteData.

$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 bytes to be uploaded.
$contentType contains is the value of the Content-Type header. An empty string may be passed to allow Chilkat to automatically determine the Content-Type based on the filename extension.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
AddFileForUpload
public function AddFileForUpload(string $name, string $filePath): bool

Adds a file to an upload request. To create a file upload request, set the ContentType property = multipart/form-data 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 true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
AddFileForUpload2
public function AddFileForUpload2(string $name, string $filePath, string $contentType): bool

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 true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
AddHeader
public function AddHeader(string $name, string $value): void

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
public function AddMwsSignature(string $domain, string $mwsSecretKey): bool
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.

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

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

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
AddParam
public function AddParam(string $name, string $value): void

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
public function AddStringForUpload(string $name, string $filename, string $strData, string $charset): bool

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

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
AddStringForUpload2
public function AddStringForUpload2(string $name, string $filename, string $strData, string $charset, string $contentType): bool

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 true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
AddSubHeader
public function AddSubHeader(int $index, string $name, string $value): bool
Introduced in version 9.5.0.55

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

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
GenerateRequestFile
public function GenerateRequestFile(string $path): bool
Introduced in version 9.5.0.64

The same as GenerateRequestText, except the generated request is written to the file specified by $path.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
GenerateRequestText
public function GenerateRequestText(): ?string

More Information and Examples
top
GetUrlEncodedParams
public function GetUrlEncodedParams(): ?string

Returns the request parameters in URL encoded form (i.e. in the exact form that would be sent if the ContentType property was application/x-www-form-urlencoded). For example, if a request has two params: param1=abc 123 and param2=abc-123, then GetUrlEncodedParams would return abc+123&param2=abc%2D123

On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns null). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
LoadBodyFromBd
public function LoadBodyFromBd(BinData $requestBody): bool
Introduced in version 9.5.0.67

Uses the contents of the $requestBody as the HTTP request body.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
LoadBodyFromFile
public function LoadBodyFromFile(string $filePath): bool

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 $filePath.
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.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
LoadBodyFromSb
public function LoadBodyFromSb(StringBuilder $requestBody, string $charset): bool
Introduced in version 9.5.0.67

Uses the contents of the $requestBody as the HTTP request body. The $charset indicates the binary representation of the string, such as utf-8, utf-16, iso-8859-*, windows-125*, etc. Any of the character encodings supported at the link below are valid.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
LoadBodyFromString
public function LoadBodyFromString(string $bodyStr, string $charset): bool

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.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
RemoveAllParams
public function RemoveAllParams(): void

Removes all request parameters.

More Information and Examples
top
RemoveHeader
public function RemoveHeader(string $name): bool

Removes all occurrences of a HTTP request header field. Always returns true.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

top
RemoveParam
public function RemoveParam(string $name): void

Removes a single HTTP request parameter by name.

More Information and Examples
top
SetFromUrl
public function SetFromUrl(string $url): void

Parses a URL and sets the Path and query parameters (NumParams, GetParam, GetParamName, GetParamValue).

More Information and Examples
top
StreamBodyFromFile
public function StreamBodyFromFile(string $filePath): bool

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 true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.

More Information and Examples
top
StreamChunkFromFile
public function StreamChunkFromFile(string $path, string $offset, string $numBytes): bool
Introduced in version 9.5.0.55

This method is the same as StreamBodyFromFile, but allows for an offset and number of bytes to be specified. The $offset and $numBytes are integers passed as strings.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.
