firewall - Symfony 5 : Can I have a main and admin firewalls in security. yaml？

Question

我正在关注 excellent french course专为 symfony 4 设计并开始适应 symfony 5。

我正在尝试在用户进入管理/注销路由时创建重定向路由。根据Symfony 5 official documentation ，我根本不需要在注销函数中写任何东西。

这是关于为管理员用户和没有权限的用户创建防火墙。实际上，我为管理员启用了一条注销路线，但它被解释而不是通过 security.yaml 进程注销管理员......原因是我在主防火墙中被阻止，而不是进入管理防火墙。结果，Symfony 抛出这个 error in screenshot ，说:“ Controller 必须返回一个“Symfony\Component\HttpFoundation\Response”对象，但它返回了 null。您是否忘记在 Controller 中的某处添加 return 语句？”。

我想真正的问题是:我可以切换防火墙吗？我的目标只是为普通用户和管理员用户提供正确的连接形式，以及传达他们自己的重定向路由的正确断开路由。你有什么主意吗 ？我以为每当我使用/admin/* 路由时都会选择管理防火墙...感谢您的帮助!

我将向您展示我的 security.yaml、routes.yaml、检查管理员登录表单的 Controller 、处理管理员/注销路由的 Controller 以及我的管理员注销按钮所在的 twig 模板。

在展示之前，我让您知道我可以同时登录管理员和普通用户。只有管​​理员注销路由被破坏。以下是文件。

3/5 AdminLoginFormAuthenticator.php 检查登录表单

4/5 AdminAccountController.php 处理管理/登录和管理/注销路由:

<?php

use Sensio\Bundle\FrameworkExtraBundle\Configuration\IsGranted;
use Symfony\Component\HttpFoundation\Request;

class AdminAccountController extends AbstractController
{
    /**
     * Require ROLE_ADMIN for only this controller method.
     * @IsGranted("IS_AUTHENTICATED_ANONYMOUSLY")
     * @Route("/admin/login", name="admin_account_login")
     */
    public function login(AuthenticationUtils $authenticationUtils)
    {
        // if ($this->getUser()) {
        //     return $this->redirectToRoute('target_path');
        // }

        // get the login error if there is one
        $error = $authenticationUtils->getLastAuthenticationError();
        // last username entered by the user
        $lastUsername = $authenticationUtils->getLastUsername();

        return $this->render('admin/account/login.html.twig', [
            'hasError' => $error !== null,
            'username' => $lastUsername
        ]);
    }

   /**
    * Allows admin user to log out
    * @Route("/admin/logout", name="admin_account_logout", methods={"GET"})
    * @return void
    */
    public function logout() {
        throw new \Exception('Will be intercepted before getting here');
    }
}

5/5 以及托管注销按钮的我的 Twig 标题模板的一部分:

                    <div class="dropdown-menu dropdown-menu-right" aria-labelledby="accountDropdownLink">
                        <a href="{{ path('app_admin_account_logout')}}" class="dropdown-item">Déconnexion</a>
                    </div>

是的，你可以喜欢这个

fierWallName:
        anonymous: lazy
        provider: in_database
        form_login:
            login_path: login #login of this fier wall route name
            check_path: login #login of this fier wall route name 
        logout:
            path: logout #logout of this fier wall route name
            target: home_page #target route name

你不需要只在 security.yaml 中编辑 route.yaml 文件
