[SOLVED] new (Json)Response shows blank page (Symfony HttpFoundation)

new (Json)Response shows blank page (Symfony HttpFoundation)

I am using the HttpFoundation in my small project: use \Symfony\Component\HttpFoundation\JsonResponse as JsonResponse;

Unfortunately all my responses (tried JsonResponse, Response and BinaryFileResponse) only return a blank page, no errors and the code gets executed normally, e.g.

/* Get Inputs */
if (!$data = filter_input(INPUT_GET, 'url', FILTER_VALIDATE_URL)) {
    return new JsonResponse(array(
        'result' => 'error',
        'message' => 'URL is invalid or missing'
    ));
}else{
     return new JsonResponse(array(
        'result' => 'success',
        'message' => 'FINE'
    ));

There are no errors in the logs either.

Any ideas how to approach the issue?

//UPDATE FOR CLARIFICATION

$json = new JsonResponse(array(
    'result' => 'error',
    'message' => 'Encrypt is invalid or missing'
));

echo $json;

returns HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: application/json {"result":"error","message":"Encrypt is invalid or missing"}

but why does the return not work?

Solution

You're not using the full stack framework, so you need to be sure that your front controller or equivalent calls $response->send(); to deliver the response to the client.
