If you use Symfony Http foundation and JMS Serializer, this library allows to return raw objects and status code as a controller response so that it will be serialized later by serializer and converted to a Symfony Response.

The problem: Symfony converts response content to string if we use Symfony Response, or if we return a raw object and use a filter listener, then we can't pass status code.


Install via composer

    "require": {
        "alcalyn/serializable-api-response": "~1.0"


Return a non-yet-serialized response in your controller:

use Symfony\Component\HttpKernel\Exception\ConflictHttpException;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Alcalyn\SerializableApiResponse\ApiResponse;
use Acme\UserApi\Exception\UserAlreadyExistsException;

class UserController
     * @param Request $request
     * @return ApiResponse
     * @throws ConflictHttpException if username already exists.
    public function registerUserAction(Request $request)
        $username = $request->request->get('username');
        $password = $request->request->get('password');

        try {
            $user = $this->userManager->createUser($username, $password);
        } catch (UserAlreadyExistsException $e) {
            throw new ConflictHttpException('An user with username "'.$username.'" already exists.', $e);

        return new ApiResponse($user, Response::HTTP_CREATED);

Register ApiResponse Filter Listener:

In Silex:

use Symfony\Component\HttpKernel\KernelEvents;
use Alcalyn\SerializableApiResponse\ApiResponseFilter;

// Register reponse filter as a service
$this['acme.listener.api_response_filter'] = function () {
    $serializer = $this['serializer']; // Assuming your serializer service has this name

    return new ApiResponseFilter($serializer);

// Listen Kernel response to convert ApiResponse with raw object to Symfony Response with serialized data
$this->on(KernelEvents::VIEW, function ($event) {
