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.
First, create a class that implements
AccessDeniedHandlerInterface.
This interface defines one method called handle()
where you can implement whatever
logic that should execute when access is denied for the current user (e.g. send a
mail, log a message, or generally return a custom response):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
namespace App\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);
}
}
If you're using the default services.yaml configuration, you're done! Symfony will automatically know about your new service. You can then configure it under your firewall:
- YAML
- XML
- PHP
1 2 3 4 5 6 7
# config/packages/security.yaml
firewalls:
# ...
main:
# ...
access_denied_handler: App\Security\AccessDeniedHandler
That's it! Any AccessDeniedException
thrown by code under the main
firewall
will now be handled by your service.
