Question

I need to write a basic authentication handler. In my onAuthenticationFailure, just for testing, i’m var-dumping $request. it should work using bad credentials, but nothing happened.

I guess there is something wrong in my src\Acme\TestBundle\resources\Config\services.yml:

services:
    authentication_handler:
        class: Acme\TestBundle\Handler\AuthenticationHandler

This is the test class, use statement removed for readability:

namespace Acme\TestBundle\Handler;

class AuthenticationHandler implements AuthenticationSuccessHandlerInterface,
    AuthenticationFailureHandlerInterface, LogoutSuccessHandlerInterface
{

    function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $user = $token->getUser();
    }

    function onAuthenticationFailure(Request $request,
        AuthenticationException $exception)
    {
        var_dump($request);
        die();
    }

    public function onLogoutSuccess(Request $request)
    {
    }

}

You need to set the handler in the security.yml file:

form_login:
    success_handler: authentication_handler
    failure_handler: authentication_handler
logout:
    success_handler: authentication_handler
