Symfony 4:在自定义控制器中注销用户

use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class LogoutController extends AbstractController
{
    /**
     * @Route("/logout", name="logout")
     */
    public function logout(AuthenticationUtils $authenticationUtils): Response
    {
        // 获取当前用户
        $user = $this->getUser();

        // 执行注销操作
        $this->get('security.token_storage')->setToken(null);
        $this->get('session')->invalidate();

        // 返回注销成功的页面或重定向到其他页面
        return $this->redirectToRoute('homepage');
    }
}

logout:
    path: /logout
    controller: App\Controller\LogoutController::logout
