authentication - Symfony2 - 成功登录后重定向

Question

我刚刚开始学习 Symfony 2 教程。我创建了一个包含用户类的 bundle ，并尝试按照说明设置登录过程。我想我快到了，但是我目前正处于最后一个障碍。

我设置了一个包:Dan\AuthBundle，其中包含我的用户类和另一个包:Dan\HelloBundle，我希望只允许登录用户访问。

我的security.yml文件如下:

security:
    encoders:
        Dan\AuthBundle\Entity\User: sha512

    providers:
        main:
            entity: { class: Dan\AuthBundle\Entity\User, property: username }
        administrators:
            entity: { class: DanAuthBundle:User }

    firewalls:
        secured_area:
            pattern:    ^/*
            form_login:
                check_path: /login_check
                login_path: /login
                always_use_default_target_path: false
                default_target_path: /hello

    access_control:
        - { path: ^/hello/.* }

主要的 routing.yml 文件如下所示:

DanAuthBundle:
    resource: "@DanAuthBundle/Resources/config/routing.yml"
    prefix:   /auth/

DanHelloBundle_homepage:
pattern:  /hello/
defaults: { _controller: DanHelloBundle:Default:index }

login:
    pattern: /login
    defaults: {_controller: DanAuthBundle:Default:login }

login_check:
    pattern: /login_check

我手动创建了我的用户类的几个实例。

如果我尝试访问 url/hello，我会正确地重定向到登录页面。如果我输入了错误的详细信息，我会在模板中收到正确的消息，但是，当我使用正确的详细信息登录时，我会收到 324(空响应)错误(此时，浏览器中显示的 url是 login_check)。

通过阅读文档，我认为我应该被重定向到我最初尝试访问的页面？

http://symfony.com/doc/current/book/security.html#using-a-traditional-login-form

By default, if the submitted credentials are correct, the user will be redirected to the original page that was requested (e.g. /admin/foo). If the user originally went straight to the login page, he'll be redirected to the homepage. This can be highly customized, allowing you to, for example, redirect the user to a specific URL.

另外，如果我在输入正确的详细信息后尝试访问该页面，我会再次被重定向到登录页面。

谁能看看我是否遗漏了什么明显的东西？

这是来 self 的日志文件:

任何建议表示赞赏。

谢谢。

// if you're using Symfony 2.0
$key = '_security.target_path';
// if you're using Symfony 2.1 or greater
// where "main" is the name of your firewall in security.yml
$key = '_security.main.target_path';

// try to redirect to the last page, or fallback to the homepage
if ($this->container->get('session')->has($key)) {
  $url = $this->container->get('session')->get($key);
  $this->container->get('session')->remove($key);
} else {
  $url = $this->container->get('router')->generate('homepage');
}

return new RedirectResponse($url);
