Question

Background:

I am writing a RESTful API on symfony. I want the client to be able to post to a url using the content type application/json and post a json object of form that the controller action is looking for.

Im using a pretty basic controller setup for this. Lets assume for demonstration purposes that im trying to authenticate a simple username password combo.

public function loginAction( Request $request )
{
    $user = new ApiUser();
    $form = $this->createForm(new ApiUserType(), $user);
    if ( "POST" == $request->getMethod() ) {
        $form->bindRequest($request);
        if ( $form->isValid() ) {
            $em = $this->getDoctrine()->getEntityManager();
            $repo = $this->getDoctrine()->getRepository('ApiBundle:ApiUser');
            $userData = $repo->findOneByUsername($user->getUsername());
            if ( is_object($userData) ) {
                /** do stuff for authenticating **/
            }
            else{
                return new Response(json_encode(array('error'=>'no user by that username found')));
            }
        else{
            return new Response(json_encode(array('error'=>'invalid form')));
        }
    }
}

Now the issue that i have, and have i have tried var_dumping this till the cows come home, is that for what ever reason symfony does not want to take the application/json content-body and use that data to populate the form data.

Form name: api_apiuser

Fields: username, password

What would be the best way to handle this type of task. I am open to suggestions as long as i can get this working. Thanks for your time with the matter.

Ive actually found a similar way to fix this, AFTER checking if the method is post and before binding the request to the form i do this:

if ( "POST" === $request->getMethod() ) {
    if (0 === strpos($request->headers->get('Content-Type'), 'application/json')){
        $data = json_decode($request->getContent(), true);
        $request->request->replace(is_array($data) ? $data : array());
    }
    $form->bindRequest($request);
    /** Rest of logic **/
}
