PHP Proxy

This is a HTTP/HTTPS proxy script that forwards requests to a different server and returns the response. The Proxy class uses Symfony request/response objects as input/output, and uses Guzzle to do the actual http request.

Installation

Install using composer:

composer require jenssegers/proxy

Examples

The following example creates a request object, based on the current browser request, and forwards it to example.com. The RemoveEncodingFilter removes the encoding headers from the original response so that the current webserver can set these correctly.

use Proxy\Factory;
use Proxy\Response\Filter\RemoveEncodingFilter;
use Symfony\Component\HttpFoundation\Request;

require 'vendor/autoload.php';

// Create the proxy factory.
$proxy = Factory::create();

// Add a response filter that removes the encoding headers.
$proxy->addResponseFilter(new RemoveEncodingFilter());

// Create a Symfony request based on the current browser request.
$request = Request::createFromGlobals();

// Forward the request and get the response.
$response = $proxy->forward($request)->to('http://example.com');

// Output response to the browser.
$response->send();

You can also proxy "custom" requests:

use Proxy\Factory;
use Proxy\Response\Filter\RemoveEncodingFilter;
use Symfony\Component\HttpFoundation\Request;

require 'vendor/autoload.php';

// Create the proxy factory.
$proxy = Factory::create();

// Add a response filter that removes the encoding headers.
$proxy->addResponseFilter(new RemoveEncodingFilter());

// Create a custom request.
$request = Request::create(
    '/hello-world',
    'GET',
    array('name' => 'Fabien')
);

// Forward the request and get the response.
$response = $proxy->forward($request)->to('http://example.com');

// Output response to the browser.
$response->send();

The following example uses a shortcut that is built into the factory:

use Proxy\Factory;
use Proxy\Response\Filter\RemoveEncodingFilter;
use Symfony\Component\HttpFoundation\Request;

require 'vendor/autoload.php';

// Create a Symfony request based on the current browser request.
$request = Request::createFromGlobals();

// Forward the request and get the response.
$response = Factory::forward($request)->to('http://example.com');

// Output response to the browser.
$response->send();
