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) {
$this['acme.listener.api_response_filter']->onKernelView($event);
