Unaltered PSR HTTP Message Bridge Bundle

An opt-in and drop-in replacement bundle for symfony/psr-http-message-bridge that doesn't alter the query parameters.

This package register a decorator for the service PsrHttpFactory in your Symfony application.

The only difference with the original class from symfony/psr-http-message-bridge is that it doesn't alter the query parameters when converting a Symfony request into a PSR7 request.



Symfony's Request class uses parse_str() function to parse the query string, but parse_str() alter the parameter key if it contains . and replaces them with _. This issue makes the Request object harder to work with when we some logic needs to heavily rely on query parameters (API Platform, CAS, ... ).


  • PHP >= 7.1.3
  • Symfony >= 4


composer require loophp/unaltered-psr-http-message-bridge-bundle




namespace App\Controller;

use Psr\Http\Message\RequestInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bridge\PsrHttpMessage\HttpMessageFactoryInterface;

final class MainController {
     * @Route("/api/offers", name="api_offers")
     * @return \Symfony\Component\HttpFoundation\Response
    public function __invoke(
        Request $request,
        HttpMessageFactoryInterface $httpMessageFactory,
        RequestInterface $psrRequest
    ): Response {
        // Using Symfony's request object.
        $uri = $request->getUri(); // http://localhost:8000/api/offers?product_color=red
        $params = $request->query->all(); // [ 'product_color' => 'red' ]

        // Using PSR Request.
        $psrRequest = $httpMessageFactory->createRequest($request);
        $uri = (string) $psrRequest->getUri(); // http://localhost:8000/api/offers?product.color=red
        $params = $psrRequest->getUri()->getQuery(); // 'product.color=red'

        // Or directly by requesting the PSR request through RequestInterface parameter.

        return new Response('');

Notice that the query string parameters has been altered, from field.filter to field_filter when using the Symfony Request object.


There is no configuration and you do not have to do anything besides requiring this package in your application.
