Symfony 从 4.1 升级到 4.4 authenticationutils servicelocator

Question

我正在尝试将 Symfony 应用程序从 4.1 升级到 4.4，但我在 SecurityController 中出现身份验证错误

public function loginAction (Request $request)
    {
        /* var AuthenticationUtils $authUtils */
        $authUtils= $this->get('security.authentication_utils');
        
        // get the login error if there is one
        $error = $authUtils->getLastAuthenticationError();
        
        // last username entered by the user
        $lastUsername = $authUtils->getLastUsername();

        return $this->render('admin/user/login.html.twig', array(
            'error'         => $error,
            'last_username' => $lastUsername,
        ));
    }

但是升级后出现这个错误

我该如何解决这个错误？

Answer 1

..如@dbrunmann

所述

public function loginAction (Request $request, AuthenticationUtils $authUtils)
    {        
        // get the login error if there is one
        $error = $authUtils->getLastAuthenticationError();
        
        // last username entered by the user
        $lastUsername = $authUtils->getLastUsername();

        return $this->render('admin/user/login.html.twig', array(
            'error'         => $error,
            'last_username' => $lastUsername,
        ));
    }

使用 php bon\console debug:autowiring <some_service_name> - 找出使用哪个 typhint 来获得正确的服务

例如php bin\console debug:autowiring utils会给你

Symfony 从 4.1 升级到 4.4 authenticationutils servicelocator
