CakePHP Http Library
This library provides a PSR-15 Http middleware server, PSR-7 Request and Response objects, and a PSR-18 Http Client. Together these classes let you handle incoming server requests and send outgoing HTTP requests.
Using the Http Client
Sending requests is straight forward. Doing a GET request looks like
use Cake\Http\Client;
$http = new Client();
// Simple get
$response = $http->get('http://example.com/test.html');
// Simple get with querystring
$response = $http->get('http://example.com/search', ['q' => 'widget']);
// Simple get with querystring & additional headers
$response = $http->get('http://example.com/search', ['q' => 'widget'], [
'headers' => ['X-Requested-With' => 'XMLHttpRequest']
]);To learn more read the Http Client documentation.
Using the Http Server
The Http Server allows an HttpApplicationInterface to process requests and
emit responses. To get started first implement the
Cake\Http\HttpApplicationInterface A minimal example would could look like:
namespace App
use Cake\Core\HttpApplicationInterface;
use Cake\Http\MiddlewareQueue;
class Application implements HttpApplicationInterface
{
/**
* Load all the application configuration and bootstrap logic.
*
* @return void
*/
public function bootstrap(): void
{
// Load configuration here. This is the first
// method Cake\Http\Server will call on your application.
}
/**
* Define the HTTP middleware layers for an application.
*
* @param \Cake\Http\MiddlewareQueue $middleware The middleware queue to set in your App Class
* @return \Cake\Http\MiddlewareQueue
*/
public function middleware(MiddlewareQueue $middleware): MiddlewareQueue
{
// Add middleware for your application.
return $middleware;
}
}Once you have an application with some middleware. You can start accepting
requests. In your application's webroot, you can add an index.php and process
requests:
<?php
// in webroot/index.php
require dirname(__DIR__) . '/vendor/autoload.php';
use App\Application;
use Cake\Http\Server;
// Bind your application to the server.
$server = new Server(new Application());
// Run the request/response through the application and emit the response.
$server->emit($server->run());You can then run your application using PHP's built in webserver:
php -S localhost:8765 -t ./webroot ./webroot/index.phpFor more information on middleware, consult the documentation
