Installation
composer require nyholm/psr7
If you are using Symfony Flex then you get all message factories registered as services.
Usage
The PSR-7 objects do not contain any other public methods than those defined in the PSR-7 specification.
Create objects
Use the PSR-17 factory to create requests, streams, URIs etc.
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$stream = $psr17Factory->createStream('foobar');
Sending a request
With HTTPlug or any other PSR-18 (HTTP client) you may send requests like:
composer require kriswallsmith/buzz
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$psr18Client = new \Buzz\Client\Curl($psr17Factory);
$request = $psr17Factory->createRequest('GET', 'http://tnyholm.se');
$response = $psr18Client->sendRequest($request);
Create server requests
The nyholm/psr7-server
package can be used
to create server requests from PHP superglobals.
composer require nyholm/psr7-server
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$creator = new \Nyholm\Psr7Server\ServerRequestCreator(
$psr17Factory, // ServerRequestFactory
$psr17Factory, // UriFactory
$psr17Factory, // UploadedFileFactory
$psr17Factory // StreamFactory
);
$serverRequest = $creator->fromGlobals();
Emitting a response
composer require zendframework/zend-httphandlerrunner
$psr17Factory = new \Nyholm\Psr7\Factory\Psr17Factory();
$responseBody = $psr17Factory->createStream('Hello world');
$response = $psr17Factory->createResponse(200)->withBody($responseBody);
(new \Zend\HttpHandlerRunner\Emitter\SapiEmitter())->emit($response);
Our goal
This package is currently maintained by Tobias Nyholm and Martijn van der Ven. They have decided that the goal of this library should be to provide a super strict implementation of PSR-7 that is blazing fast.
The package will never include any extra features nor helper methods. All our classes and functions exist because they are required to fulfill the PSR-7 specification.
