How to Create a Custom Access Denied Handler

When your application throws an AccessDeniedException, you can handle this exception with a service to return a custom response.

Each firewall context can define its own custom access denied handler:

  • YAML
  • XML
  • PHP

# app/config/security.yml
firewalls:
    foo:
        # ...
        access_denied_handler: app.security.access_denied_handler

Your handler must implement the AccessDeniedHandlerInterface. This interface defines one method called handle() that implements the logic to execute when access is denied to the current user (send a mail, log a message, or generally return a custom response).

namespace AppBundle\Security;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;
use Symfony\Component\Security\Http\Authorization\AccessDeniedHandlerInterface;

class AccessDeniedHandler implements AccessDeniedHandlerInterface
{
    public function handle(Request $request, AccessDeniedException $accessDeniedException)
    {
        // ...

        return new Response($content, 403);
    }
}

Then, register the service for the access denied handler:

  • YAML
  • XML
  • PHP

# app/config/services.yml
services:
    app.security.access_denied_handler:
        class: AppBundle\Security\AccessDeniedHandler

That's it! Any AccessDeniedException thrown by the foo firewall will now be handled by your service.
