# Chilkat HttpRequest — PHP ActiveX — v11.7.0

> Chilkat 11.7.0 · language=phpx · class=HttpRequest
> Other versions: replace `11.7.0` in this URL. Other languages: `https://www.chilkatsoft.com/ai-docs/v/11.7.0/<lang>/classes/HttpRequest.md`.
> Language-wide rules (install, unlock, error model, strings/bytes): `https://www.chilkatsoft.com/ai-docs/v/11.7.0/phpx/guide.md`.

## Purpose

**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.

For an extended overview, see [HttpRequest Class Overview](https://www.chilkatsoft.com/httprequest_class_overview.asp).

## Object creation, unlocking and error handling

**Object Creation**

```php
Chilkat v10.0.0 or greater:
$obj = new COM("Chilkat.HttpRequest");
Chilkat v9.5.0.*:
$obj = new COM("Chilkat_9_5_0.HttpRequest");
```

Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in PHP ActiveX.

How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called.

## Properties

### HttpRequest.Boundary

`Chilkat 11.7.0 · phpx · HttpRequest · Boundary · property · read/write · since 9.5.0.49`

```php
string Boundary
```

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.

### HttpRequest.Charset

`Chilkat 11.7.0 · phpx · HttpRequest · Charset · property · read/write`

```php
string Charset
```

**Full documentation for this property (same in every language):** [How Charset Matters with HTTP Query Parameters](https://www.chilkatsoft.com/ai-docs/v/11.7.0/articles/how_charset_matters_with_http_query_params.md)

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

### HttpRequest.ContentType

`Chilkat 11.7.0 · phpx · HttpRequest · ContentType · property · read/write`

```php
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.

### HttpRequest.EntireHeader

`Chilkat 11.7.0 · phpx · HttpRequest · EntireHeader · property · read/write`

```php
string EntireHeader
```

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

### HttpRequest.HttpVerb

`Chilkat 11.7.0 · phpx · HttpRequest · HttpVerb · property · read/write`

```php
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.

### HttpRequest.HttpVersion

`Chilkat 11.7.0 · phpx · HttpRequest · HttpVersion · property · read/write`

```php
string HttpVersion
```

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

### HttpRequest.NumHeaderFields

`Chilkat 11.7.0 · phpx · HttpRequest · NumHeaderFields · property · read-only`

```php
int NumHeaderFields (read-only)
```

Returns the number of request header fields.

### HttpRequest.NumParams

`Chilkat 11.7.0 · phpx · HttpRequest · NumParams · property · read-only`

```php
int NumParams (read-only)
```

Returns the number of query parameters.

### HttpRequest.Path

`Chilkat 11.7.0 · phpx · HttpRequest · Path · property · read/write`

```php
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).

### HttpRequest.SendCharset

`Chilkat 11.7.0 · phpx · HttpRequest · SendCharset · property · read/write`

```php
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`.

## Methods

### HttpRequest.AddBdForUpload

`Chilkat 11.7.0 · phpx · HttpRequest · AddBdForUpload · method · since 9.5.0.76`

```php
bool AddBdForUpload(string name, string remoteFilename, Chilkat.BinData byteData, string contentType)
```

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 for success, false for failure.

### HttpRequest.AddBytesForUpload

`Chilkat 11.7.0 · phpx · HttpRequest · AddBytesForUpload · method`

```php
bool AddBytesForUpload(string name, string remoteFileName, VARIANT 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, set the ContentType property = `multipart/form-data` 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 true for success, false for failure.

### HttpRequest.AddBytesForUpload2

`Chilkat 11.7.0 · phpx · HttpRequest · AddBytesForUpload2 · method`

```php
bool AddBytesForUpload2(string name, string remoteFileName, VARIANT byteData, string 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 true for success, false for failure.

### HttpRequest.AddFileForUpload

`Chilkat 11.7.0 · phpx · HttpRequest · AddFileForUpload · method`

```php
bool AddFileForUpload(string name, string filePath)
```

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 for success, false for failure.

### HttpRequest.AddFileForUpload2

`Chilkat 11.7.0 · phpx · HttpRequest · AddFileForUpload2 · method`

```php
bool AddFileForUpload2(string name, string filePath, string 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 true for success, false for failure.

### HttpRequest.AddHeader

`Chilkat 11.7.0 · phpx · HttpRequest · AddHeader · method`

```php
void AddHeader(string name, string 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.)

### HttpRequest.AddMwsSignature

`Chilkat 11.7.0 · phpx · HttpRequest · AddMwsSignature · method · since 9.5.0.66`

```php
bool AddMwsSignature(string domain, string mwsSecretKey)
```

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 for success, false for failure.

### HttpRequest.AddParam

`Chilkat 11.7.0 · phpx · HttpRequest · AddParam · method`

```php
void AddParam(string name, string 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.

### HttpRequest.AddStringForUpload

`Chilkat 11.7.0 · phpx · HttpRequest · AddStringForUpload · method`

```php
bool AddStringForUpload(string name, string filename, string strData, string charset)
```

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

Returns true for success, false for failure.

### HttpRequest.AddStringForUpload2

`Chilkat 11.7.0 · phpx · HttpRequest · AddStringForUpload2 · method`

```php
bool AddStringForUpload2(string name, string filename, string strData, string charset, string 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 true for success, false for failure.

### HttpRequest.AddSubHeader

`Chilkat 11.7.0 · phpx · HttpRequest · AddSubHeader · method · since 9.5.0.55`

```php
bool AddSubHeader(int index, string name, string value)
```

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 for success, false for failure.

### HttpRequest.GenerateRequestFile

`Chilkat 11.7.0 · phpx · HttpRequest · GenerateRequestFile · method · since 9.5.0.64`

```php
bool GenerateRequestFile(string path)
```

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

### HttpRequest.LoadBodyFromBytes

`Chilkat 11.7.0 · phpx · HttpRequest · LoadBodyFromBytes · method`

```php
bool LoadBodyFromBytes(VARIANT byteData)
```

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 the `byteData`.  
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 for success, false for failure.

### HttpRequest.LoadBodyFromFile

`Chilkat 11.7.0 · phpx · HttpRequest · LoadBodyFromFile · method`

```php
bool LoadBodyFromFile(string filePath)
```

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.

- [Chilkat Supported Character Encodings](http://cknotes.com/chilkat-charsets-character-encodings-supported/)

### HttpRequest.LoadBodyFromString

`Chilkat 11.7.0 · phpx · HttpRequest · LoadBodyFromString · method`

```php
bool LoadBodyFromString(string bodyStr, string 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.

Returns true for success, false for failure.

### HttpRequest.RemoveAllParams

`Chilkat 11.7.0 · phpx · HttpRequest · RemoveAllParams · method`

```php
void RemoveAllParams()
```

Removes all request parameters.

### HttpRequest.RemoveHeader

`Chilkat 11.7.0 · phpx · HttpRequest · RemoveHeader · method`

```php
bool RemoveHeader(string name)
```

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

Returns true for success, false for failure.

### HttpRequest.RemoveParam

`Chilkat 11.7.0 · phpx · HttpRequest · RemoveParam · method`

```php
void RemoveParam(string name)
```

Removes a single HTTP request parameter by name.

### HttpRequest.SetFromUrl

`Chilkat 11.7.0 · phpx · HttpRequest · SetFromUrl · method`

```php
void SetFromUrl(string url)
```

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

### HttpRequest.StreamBodyFromFile

`Chilkat 11.7.0 · phpx · HttpRequest · StreamBodyFromFile · method`

```php
bool StreamBodyFromFile(string 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 true for success, false for failure.

### HttpRequest.StreamChunkFromFile

`Chilkat 11.7.0 · phpx · HttpRequest · StreamChunkFromFile · method · since 9.5.0.55`

```php
bool StreamChunkFromFile(string path, string offset, string numBytes)
