PSR 7/17 implementation switching

This bundle requires a PSR 7/17 implementation to operate. We recommend that you use nyholm/psr7 as this is the one Symfony suggests themselves.

The recommended implementation requires no extra configuration. Check out the example below to see how to use a different one.

Example

In this example we'll use the zendframework/zend-diactoros package.

  1. Require the package via Composer:

    composer require zendframework/zend-diactoros

  2. Register factory services and alias them to PSR interfaces in your service configuration file:

    services:
    # Register services
    Zend\Diactoros\ServerRequestFactory: ~
    Zend\Diactoros\StreamFactory: ~
    Zend\Diactoros\UploadedFileFactory: ~
    Zend\Diactoros\ResponseFactory: ~

    # Setup autowiring aliases
    Psr\Http\Message\ServerRequestFactoryInterface: '@Zend\Diactoros\ServerRequestFactory'
    Psr\Http\Message\StreamFactoryInterface: '@Zend\Diactoros\StreamFactory'
    Psr\Http\Message\UploadedFileFactoryInterface: '@Zend\Diactoros\UploadedFileFactory'
    Psr\Http\Message\ResponseFactoryInterface: '@Zend\Diactoros\ResponseFactory'
