single: PSR-7
The PSR-7 bridge converts
HttpFoundation </components/http_foundation>
objects from and to objects implementing HTTP message interfaces defined by the PSR-7.
$ composer require symfony/psr-http-message-bridge
Alternatively, you can clone the https://github.com/symfony/psr-http-message-bridge repository.
The bridge also needs a PSR-7 and PSR-17 implementation to allow converting HttpFoundation objects to PSR-7 objects. See a full list of PSR-17 libraries on that provide psr/http-factory-implementation on Packagist.org. Example:
$ composer require nyholm/psr7
The bridge provides an interface of a factory called Symfony\\Bridge\\PsrHttpMessage\\HttpMessageFactoryInterface
that builds objects implementing PSR-7 interfaces from HttpFoundation objects.
The following code snippet explains how to convert a Symfony\\Component\\HttpFoundation\\Request
to a Nyholm\Psr7\ServerRequest
class implementing the Psr\Http\Message\ServerRequestInterface
interface:
use Nyholm\Psr7\Factory\Psr17Factory;
use Symfony\Bridge\PsrHttpMessage\Factory\PsrHttpFactory;
use Symfony\Component\HttpFoundation\Request;
$symfonyRequest = new Request([], [], [], [], [], ['HTTP_HOST' => 'dunglas.fr'], 'Content');
// The HTTP_HOST server key must be set to avoid an unexpected error
$psr17Factory = new Psr17Factory();
$psrHttpFactory = new PsrHttpFactory($psr17Factory, $psr17Factory, $psr17Factory, $psr17Factory);
$psrRequest = $psrHttpFactory->createRequest($symfonyRequest);
And now from a Symfony\\Component\\HttpFoundation\\Response
to a Nyholm\Psr7\Response
class implementing the Psr\Http\Message\ResponseInterface
interface:
use Nyholm\Psr7\Factory\Psr17Factory;
use Symfony\Bridge\PsrHttpMessage\Factory\PsrHttpFactory;
use Symfony\Component\HttpFoundation\Response;
$symfonyResponse = new Response('Content');
$psr17Factory = new Psr17Factory();
$psrHttpFactory = new PsrHttpFactory($psr17Factory, $psr17Factory, $psr17Factory, $psr17Factory);
$psrResponse = $psrHttpFactory->createResponse($symfonyResponse);
On the other hand, the bridge provide a factory interface called Symfony\\Bridge\\PsrHttpMessage\\HttpFoundationFactoryInterface
that builds HttpFoundation objects from objects implementing PSR-7 interfaces.
The next snippet explain how to convert an object implementing the Psr\Http\Message\ServerRequestInterface
interface to a Symfony\\Component\\HttpFoundation\\Request
instance:
use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
// $psrRequest is an instance of Psr\Http\Message\ServerRequestInterface
$httpFoundationFactory = new HttpFoundationFactory();
$symfonyRequest = $httpFoundationFactory->createRequest($psrRequest);
From an object implementing the Psr\Http\Message\ResponseInterface
to a Symfony\\Component\\HttpFoundation\\Response
instance:
use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
// $psrResponse is an instance of Psr\Http\Message\ResponseInterface
$httpFoundationFactory = new HttpFoundationFactory();
$symfonyResponse = $httpFoundationFactory->createResponse($psrResponse);
