cakephp/http

This library provides a PSR-15 Http middleware server, PSR-7 Request and Response objects, PSR-17 HTTP Factories, and 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 could look like:

namespace App;

use Cake\Core\HttpApplicationInterface;
use Cake\Http\MiddlewareQueue;
use Cake\Http\Response;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

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 $middlewareQueue The middleware queue to set in your App Class
 * @return \Cake\Http\MiddlewareQueue
 */
 public function middleware(MiddlewareQueue $middlewareQueue): MiddlewareQueue
 {
 // Add middleware for your application.
 return $middlewareQueue;
 }

 /**
 * Handle incoming server request and return a response.
 *
 * @param \Psr\Http\Message\ServerRequestInterface $request The request
 * @return \Psr\Http\Message\ResponseInterface
 */
 public function handle(ServerRequestInterface $request): ResponseInterface
 {
 return new Response(['body'=>'Hello World!']);
 }
}

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.php
