The Request Class
Zend\Http\Request
is responsible for providing a fluent API that allows a
developer to interact with all the various parts of an HTTP request.
A typical HTTP request looks like this:
| METHOD | URI | VERSION |
| HEADERS |
| BODY |
In simplified terms, the request consists of a method, URI, and HTTP version number; together, they make up the "Request Line." This line is followed by zero or more HTTP headers, which is followed by an empty line and then the request body; the body is typically used when a client wishes to send data — which could be urlencoded parameters, a JSON document, an XML document, or even one or more files — to the server. More information on the structure and specification of a HTTP request can be found in RFC-2616 on the W3.org site.
Quick Start
Request objects can either be created from the provided fromString()
factory,
or, if you wish to have a completely empty object to start with, by
manually instantiating the Zend\Http\Request
class with no parameters.
use Zend\Http\Request;
$request = Request::fromString(<<<EOS
POST /foo HTTP/1.1
HeaderField1: header-field-value1
HeaderField2: header-field-value2
foo=bar
EOS
);
// OR, the completely equivalent
$request = new Request();
$request->setMethod(Request::METHOD_POST);
$request->setUri('/foo');
$request->getHeaders()->addHeaders([
'HeaderField1' => 'header-field-value1',
'HeaderField2' => 'header-field-value2',
]);
$request->getPost()->set('foo', 'bar');

Method signature | Description |
---|---|
static fromString(string $string) : Request |
A factory that produces a Request object from a well-formed HTTP request message string. |
setMethod(string $method) : self |
Set the method for this request. |
getMethod() : string |
Return the method for this request. |
setUri(string|Uri $uri) : self |
Set the URI/URL for this request; this can be a string or an instance of Zend\Uri\Http . |
getUri() : Uri |
Return the URI for this request object. |
getUriString() : string |
Return the URI for this request object as a string. |
setVersion(string $version) : self |
Set the HTTP version for this object, one of 1.0, 1.1 or 2 (Request::VERSION_10 , Request::VERSION_11 , Request::VERSION_2 ). HTTP/2 support was added in zend-http 2.10.0. |
getVersion() : string |
Return the HTTP version for this request. |
setQuery(Parameters $query) : self |
Provide an alternate Parameter Container implementation for query parameters in this object. (This is NOT the primary API for value setting; for that, see getQuery() ). |
getQuery(string|null $name, mixed|null $default) : null|string|Parameters |
Return the parameter container responsible for query parameters or a single query parameter based on $name . |
setPost(Parameters $post) : self |
Provide an alternate Parameter Container implementation for POST parameters in this object. (This is NOT the primary API for value setting; for that, see getPost() ). |
getPost(string|null $name, mixed|null $default) : null|string|Parameters |
Return the parameter container responsible for POST parameters or a single POST parameter, based on $name . |
getCookie() : Header\Cookie |
Return the Cookie header, this is the same as calling $request->getHeaders()->get('Cookie'); . |
setFiles(Parameters $files) : self |
Provide an alternate Parameter Container implementation for file parameters in this object, (This is NOT the primary API for value setting; for that, see getFiles() ). |
getFiles(string|null $name, mixed|null $default) : null|string|Parameters |
Return the parameter container responsible for file parameters or a single file parameter, based on $name . |
setHeaders(Headers $headers) : self |
Provide an alternate Parameter Container implementation for headers in this object, (this is NOT the primary API for value setting, for that see getHeaders() ). |
getHeaders(string|null $name, mixed|null $default) : mixed |
Return the container responsible for storing HTTP headers. This container exposes the primary API for manipulating headers set in the HTTP request. See the section on Headers for more information. Return value is based on $name ; null returns Headers , while a matched header returns a Header\HeaderInterface implementation for single-value headers or an ArrayIterator for multi-value headers. |
setMetadata(string|int|array|Traversable $spec, mixed $value) : self |
Set message metadata. Non-destructive setting of message metadata; always adds to the metadata, never overwrites the entire metadata container. |
getMetadata(null|string|int $key, null|mixed $default) : mixed |
Retrieve all metadata or a single metadatum as specified by key. |
setContent(mixed $value) : self |
Set request body (content). |
getContent() : mixed |
Get request body (content). |
isOptions() : bool |
Is this an OPTIONS method request? |
isGet() : bool |
Is this a GET method request? |
isHead() : bool |
Is this a HEAD method request? |
isPost() : bool |
Is this a POST method request? |
isPut() : bool |
Is this a PUT method request? |
isDelete() : bool |
Is this a DELETE method request? |
isTrace() : bool |
Is this a TRACE method request? |
isConnect() : bool |
Is this a CONNECT method request? |
isPatch() : bool |
Is this a PATCH method request? |
isXmlHttpRequest() : bool |
Is this a Javascript XMLHttpRequest? |
isFlashRequest() : bool |
Is this a Flash request? |
renderRequestLine() : string |
Return the formatted request line (first line) for this HTTP request. |
toString() : string |
Returns string |
__toString() : string |
Allow PHP casting of this object. |
Examples
Generating a Request object from a string
use Zend\Http\Request;
$string = "GET /foo HTTP/1.1\r\n\r\nSome Content";
$request = Request::fromString($string);
$request->getMethod(); // returns Request::METHOD_GET
$request->getUri(); // returns Zend\Uri\Http object
$request->getUriString(); // returns '/foo'
$request->getVersion(); // returns Request::VERSION_11 or '1.1'
$request->getContent(); // returns 'Some Content'
Retrieving and setting headers
use Zend\Http\Request;
use Zend\Http\Header\Cookie;
$request = new Request();
$request->getHeaders()->get('Content-Type'); // return content type
$request->getHeaders()->addHeader(new Cookie(['foo' => 'bar']));
foreach ($request->getHeaders() as $header) {
printf("%s with value %s\n", $header->getFieldName(), $header->getFieldValue());
}
Retrieving and setting GET and POST values
use Zend\Http\Request;
$request = new Request();
// getPost() and getQuery() both return, by default, a Parameters object, which
// extends ArrayObject
$request->getPost()->foo = 'Foo value';
$request->getQuery()->bar = 'Bar value';
$request->getPost('foo'); // returns 'Foo value'
$request->getQuery()->offsetGet('bar'); // returns 'Bar value'
Generating a formatted HTTP Request from a Request object
use Zend\Http\Request;
$request = new Request();
$request->setMethod(Request::METHOD_POST);
$request->setUri('/foo');
$request->getHeaders()->addHeaders([
'HeaderField1' => 'header-field-value1',
'HeaderField2' => 'header-field-value2',
]);
$request->getPost()->set('foo', 'bar');
$request->setContent($request->getPost()->toString());
echo $request->toString();
/** Will produce:
POST /foo HTTP/1.1
HeaderField1: header-field-value1
HeaderField2: header-field-value2
foo=bar
*/
