Symfony 3:如何从InteractiveLoginEvent侦听器中重定向

Question

在Symfony 3.4.0中,从一个侦听InteractiveLoginEvent我想要重定向到另一个路由的事件监听器,所以我想响应一个重定向.

但该InteractiveLoginEvent对象没有"setResponse"方法.那么使用它InteractiveLoginEvent来修改响应以便将重定向发送给用户的首选方法是什么？

Answer 1

要在成功登录后执行重定向,您可以添加自定义成功处理程序,该处理程序应实现AuthenticationSuccessHandlerInterface.

AuthenticationSuccessHandler.php

<?php

namespace AppBundle\Security\Authentication\Handler;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;

class AuthenticationSuccessHandler implements AuthenticationSuccessHandlerInterface
{
    private $router;

    public function __construct(RouterInterface $router)
    {
        $this->router = $router;
    }

    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        return new RedirectResponse($this->router->generate('homepage'));
    }
}

services.yml

   services:
       AppBundle\Security\Authentication\Handler:
           arguments: ['@router']

security.yml

security:
    # ...
    firewalls:
          form_login:
              # ...
              use_referer: false
              success_handler: AppBundle\Security\Authentication\Handler\AuthenticationSuccessHandler
