Validation inside Controller

You can try this

$payload = $request->header('X-Auth-Token');
$user =  $userModel->where('api_token',$payload)->first();

    if(!$payload || !$user) {

        $response = Response::json([
            'error' => true,
            'message' => 'Not authenticated',
            'code' => 401],
            401
        );

Thanks, the authenticate method is ok, my problem is with the other fields, like an id. Well, I see in the documentation, the Form Request redirects to the previous page and throw the error. What I'm trying is to stop in controller and throw the error, and I think it's not possible, right?

@CleytonBonamigo If you specify with your request that you accept a json response the form request will not redirect back but return a json array of errors. It uses $request->wantsJson() internally.

@pmall Well, and when I put the code? In controller? I could change the response method, but I would like to do it your way.

@CleytonBonamigo

Code is in core :

public function response(array $errors)
{
    if ($this->ajax() || $this->wantsJson())
    {
        return new JsonResponse($errors, 422);
    }

    return $this->redirector->to($this->getRedirectUrl())
                                    ->withInput($this->except($this->dontFlash))
                                    ->withErrors($errors, $this->errorBag);
}

If you want to change it you must override this method in your form request.

@CleytonBonamigo No, not in your code, i think your cUrl request headers should specify it expect json as a response.

For example it works with jquery when you send an ajax request and set the type to json.

@pmall Thanks, I tried to do that, but I was forgetting one field in header, now it works perfectly, but I will have to change the response method.

@bestmomo Yeah, exactly what I did before and what I have to do now, unfortunately I will have to override this method to a custom response, thanks.
