[Symfony 5]注销后的确认消息

在Symfony 5上,使用内置登录系统,似乎无法在注销后添加确认消息。我严格遵循了上面描述的步骤。不幸的是,SecurityController中的注销方法是无用的。我直接在登录页面上被重定向

这里有我的security.yaml文件:

security:
encoders:
    App\Entity\User:
        algorithm: auto


# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
providers:
    # used to reload user from session & other features (e.g. switch_user)
    app_user_provider:
        entity:
            class: App\Entity\User
            property: email
    # used to reload user from session & other features (e.g. switch_user)
firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false
    main:
        anonymous: lazy
        provider: app_user_provider
        guard:
            authenticators:
                - App\Security\LoginFormAuthenticator
        logout:
            path: logout
            target: login

        remember_me:
            secret:   '%kernel.secret%'
            lifetime: 604800 # 1 week in seconds
            path:     home
            always_remember_me: true

        # activate different ways to authenticate
        # https://symfony.com/doc/current/security.html#firewalls-authentication

        # https://symfony.com/doc/current/security/impersonating_user.html
        # switch_user: true

# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
    - { path: ^/logout$, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/login$, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/, roles: IS_AUTHENTICATED_FULLY }
    - { path: ^/admin, roles: [IS_AUTHENTICATED_FULLY, ROLE_ADMIN] }
    - { path: ^/profile, roles: [IS_AUTHENTICATED_FULLY, ROLE_USER] }
以及控制器:

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;

class SecurityController extends AbstractController
{
    public function login(AuthenticationUtils $authenticationUtils): Response
    {
        if ($this->getUser()) {
            return $this->redirectToRoute('home');
        }

        // get the login error if there is one
        $error = $authenticationUtils->getLastAuthenticationError();

        return $this->render('security/login.html.twig', ['last_username' => null, 'error' => $error]);
    }

    public function logout()
    {
        throw new \Exception('Don\'t forget to activate logout in security.yaml');
    }
}

?>


谢谢你的帮助

SecurityController中的注销方法实际上不会被命中,因为Symfony将拦截请求。 如果您需要在注销后执行某些操作,可以使用注销成功处理程序

namespace-App\Logout;
使用Symfony\Component\HttpFoundation\Request;
使用Symfony\Component\HttpFoundation\Response;
使用Symfony\Component\Security\Http\Logout\LogoutSuccessHandlerInterface;
类MyLogoutSuccessHandler实现LogoutSuccessHandler接口
{
/**
*{@inheritardoc}
*/
公共函数onLogoutSuccess(请求$Request)
{
//你可以在这里做任何事
返回新响应('logout successfully');//或在此处呈现细枝模板,由您决定
}
}
您可以将注销成功处理程序注册到security.yaml

防火墙:
主要内容:
匿名:懒惰
提供者:应用程序\用户\提供者
警卫:
认证者:
-App\Security\LoginFormAuthenticator
注销:
路径:注销
成功\u处理程序:App\Logout\MyLogoutSuccessHandler#假设您已为服务启用自动配置,或者需要注册处理程序

多亏了Indra Gunawan,这个解决方案才有效。我的目标是重定向到登录页面,并显示一条消息,如“您已成功注销”

在这种情况下,必须调整LogoutSuccessHandler以路由到登录页面:

namespace App\Logout;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Http\Logout\LogoutSuccessHandlerInterface;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;

class MyLogoutSuccessHandler extends AbstractController implements LogoutSuccessHandlerInterface
{

    private $urlGenerator;

    public function __construct(UrlGeneratorInterface $urlGenerator)
    {
        $this->urlGenerator = $urlGenerator;
    }

    public function onLogoutSuccess(Request $request)
    {
        return new RedirectResponse($this->urlGenerator->generate('login', ['logout' => 'success']));
    }
}
需要在routes.yaml中定义路由登录名:

login:
    path: /login
    controller: App\Controller\SecurityController::login

logout:
    path: /logout
    methods: GET
在这种情况下,注销时,您将被重定向到一个url,如:/login?logout=success

最后,您可以在twig模板中捕获注销参数,如:

    {%- if app.request('logout') -%}
        <div class="alert alert-success">{% trans %}Logout successful{% endtrans %}</div>
    {%- endif -%}   
{%-if-app.request('logout')-%}
{%trans%}注销成功{%endtrans%}
{%-endif-%}

从5.1版开始,LogoutSuccessHandlerInterface已被弃用,建议使用LogoutEvent

Symfony\Component\Security\Http\Logout\LogoutSuccessHandlerInterface不推荐使用


但是官方文档中没有关于注销事件的示例或信息

以下是注销事件的文档:

必须创建事件并实现onSymfonyComponentSecurityHttpEventLogoutEvent的方法。
这对我来说很有用

对于那些想知道如何通过新的注销定制实现外部重定向的人来说:

如中所述,创建一个新的CustomLogoutListener类并将其添加到services.yml配置中

CustomLogoutListener类应实现onSymfonyComponentSecurityHttpEventLogoutEvent方法,该方法将接收LogoutEvent作为参数,允许您设置响应:

namespace App\EventListener;

use JetBrains\PhpStorm\NoReturn;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Http\Event\LogoutEvent;

class CustomLogoutListener
{
    /**
     * @param LogoutEvent $logoutEvent
     * @return void
     */
    #[NoReturn]
    public function onSymfonyComponentSecurityHttpEventLogoutEvent(LogoutEvent $logoutEvent): void
    {
        $logoutEvent->setResponse(new RedirectResponse('https://where-you-want-to-redirect.com', Response::HTTP_MOVED_PERMANENTLY));
    }
}

# config/services.yaml
services:
    # ...
    App\EventListener\CustomLogoutListener:
        tags:
            - name: 'kernel.event_listener'
              event: 'Symfony\Component\Security\Http\Event\LogoutEvent'
              dispatcher: security.event_dispatcher.main
