How to check the existence of cookies in Symfony2?

Question

symfony

How best to check for the existence of cookies:
1 Immediately in the controller

public function storesAction(Request $request)
{
  	$city = $request->cookies->get('city');     
        if(....)
}

2 Redirect the cookie to the controller and check it there, and then return it back

public function storesAction(Request $request)
{
  	$city = $this->forward('checkCookieAction'); 
        if(....)
}

Or another option?

Answer 1

It can be defined as a service, receive a request, entity_manager (if $city is an instance of the model), and perform the necessary "checks" on some event like kernel.request. In the right place to pull the service and get the result.
