Why cookie isn't set in Laravel Lumen - php

Question

This question is the following of this question.
I have a message in my view who says : This site uses cookie [...] Close.
When user click on Close, an ajax request is send to the controller. The function is the following :
public function acceptCookie(Request $request)
{
if ($request->valid == 'accept') {
$response = new Response('acceptCookie');
if ($response->withCookie(cookie('acceptCookie', 'accepte', 44000))) {
return Response()->json(array('statut' => 'Succes'));
} else {
return Response()->json(array('statut' => 'Erreur'));
}
} else {
return Response()->json(array('statut' => 'Erreur'));
}
}
I haven't any error and JSON returns always {"statut":"Succes"}
Why the cookie isn't set ?

Answer 1

Based on the Lumen documentation, it appears as though you need to queue the cookie for a response such as the one in your example. Here's what the docs say:
Queueing A Cookie For The Next Response
If you would like to set a cookie before a response has been created,
use the Cookie::queue() method. The cookie will automatically be
attached to the final response from your application.
Cookie::queue($name, $value, $minutes);
My suggestion would be to try replacing the withCookie with queuing the cookie instead. But, you might need to rewrite the function a bit in order to accomodate because it appears as though you're trying to send to responses from one request.
Hope this works for you!

Answer 2

Based on Illuminate\Http\ResponseTrait line 28, the Illuminate\Http\Response::withCookie method returning $this.
/**
* Add a cookie to the response.
*
* #param \Symfony\Component\HttpFoundation\Cookie $cookie
* #return $this
*/
public function withCookie(Cookie $cookie)
{
$this->headers->setCookie($cookie);
return $this;
}
Means you have logic failure in your code.
// This always return Illuminate\Http\Response instance,
// thus it will never reach ELSE statement forever.
if ($response->withCookie(cookie('acceptCookie', 'accepte', 44000))) {
return Response()->json(array('statut' => 'Succes'));
} else {
return Response()->json(array('statut' => 'Erreur'));
}
