Creating an application #7 - http factories

Yii 3.0 Getting started with Yii 3

The PSR-17 specification defines interfaces for HTTP factories. These factories are used to create PSR-7 objects.

The following example shows how to create configuration for the HTTP factories, using the httpsoft/http-message package:

<?php

declare(strict_types=1);

use HttpSoft\Message\RequestFactory;
use HttpSoft\Message\ResponseFactory;
use HttpSoft\Message\ServerRequestFactory;
use HttpSoft\Message\StreamFactory;
use HttpSoft\Message\UploadedFileFactory;
use HttpSoft\Message\UriFactory;
use Psr\Http\Message\RequestFactoryInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\ServerRequestFactoryInterface;
use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Message\UploadedFileFactoryInterface;
use Psr\Http\Message\UriFactoryInterface;

return [
    RequestFactoryInterface::class => RequestFactory::class,
    ServerRequestFactoryInterface::class => ServerRequestFactory::class,
    ResponseFactoryInterface::class => ResponseFactory::class,
    StreamFactoryInterface::class => StreamFactory::class,
    UriFactoryInterface::class => UriFactory::class,
    UploadedFileFactoryInterface::class => UploadedFileFactory::class,
];

The following example shows how to create configuration for the HTTP factories, using the nyholm/psr7 package:

<?php

declare(strict_types=1);

use Nyholm\Psr7\Factory\Psr17Factory;
use Psr\Http\Message\RequestFactoryInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\ServerRequestFactoryInterface;
use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Message\UploadedFileFactoryInterface;
use Psr\Http\Message\UriFactoryInterface;

return [
    RequestFactoryInterface::class => Psr17Factory::class,
    ServerRequestFactoryInterface::class => Psr17Factory::class,
    ResponseFactoryInterface::class => Psr17Factory::class,
    StreamFactoryInterface::class => Psr17Factory::class,
    UriFactoryInterface::class => Psr17Factory::class,
    UploadedFileFactoryInterface::class => Psr17Factory::class,
];

Both packages provide the same interfaces, so you can use any of them.
