symfony2仅匿名登录

Question

我想限制登录用户的登录路径，

security.yml

security:
encoders:

    Site\Bundle\AdminBundle\Entity\Users:
        algorithm: md5
        iterations: 0
        encode_as_base64:   false

role_hierarchy:
    ROLE_ADMIN: ROLE_USER
    ROLE_SUPER_ADMIN: [ ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH ]

providers:
    in_memory:
        memory:
             users:
                ryan:  { password: ryanpass, roles: 'ROLE_USER' }
                admin: { password: kitten, roles: 'ROLE_ADMIN' }
    administrators:
        entity: { class: SiteAdminBundle:Users , property: username}

firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false


    secured_area:
        pattern:   ^/
        anonymous: ~
        http_basic:
            realm: "Secured Demo Area"
        form_login:
            login_path: /login
            check_path: /login_check
        logout:
            path:   /logout
        provider: administrators
access_control:
    - { path: ^/admin/*, roles: ROLE_ADMIN }
    - { path: /login$, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/*, role: IS_AUTHENTICATED_ANONYMOUSLY }

我的登录功能：

    public function loginAction(Request $request)
{
    $session = $request->getSession();

    // get the login error if there is one
    if ($request->attributes->has(SecurityContextInterface::AUTHENTICATION_ERROR)) {
        $error = $request->attributes->get(
            SecurityContextInterface::AUTHENTICATION_ERROR
        );
    } elseif (null !== $session && $session->has(SecurityContextInterface::AUTHENTICATION_ERROR)) {
        $error = $session->get(SecurityContextInterface::AUTHENTICATION_ERROR);
        $session->remove(SecurityContextInterface::AUTHENTICATION_ERROR);
    } else {
        $error = '';
    }

    // last username entered by the user
    $lastUsername = (null === $session) ? '' : $session->get(SecurityContextInterface::LAST_USERNAME);

    return $this->render(
        'SiteSecurityBundle:Default:login.html.twig',
        array(
            // last username entered by the user
            'last_username' => $lastUsername,
            'error'         => $error,
        )
    );
}

问题是它可以工作，例如，对于/admin，只有ROLE\u admin有访问权限，ROLE\u用户号。但是/login，如果我登录或不登录，我可以访问它，在symfony2开发工具中，我看到我是匿名的，我登录了stel。。。我没有主意

有许多方法可以限制用户对某些资源的访问。下面您将看到其中的两种方法：

1）安装了SensioFrameworkExtraBundle（包含在Symfony2全栈版本中），您可以像这样为控制器使用注释

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;

class YourController extends Controller
{
    /**
     * @Security("is_granted('IS_AUTHENTICATED_ANONYMOUSLY')")
     */
    public function loginAction(Request $request)
    {
        // ...
    }
}

2）没有SensioFrameworkExtraBundle注释

use Symfony\Component\Security\Core\Exception\AccessDeniedException;

class YourController extends Controller
    {
        public function loginAction(Request $request)
        {
            if (true === $this->get('security.context')->isGranted('ROLE_ADMIN')) {
                throw new AccessDeniedException('Unable to access this page!');

                # or you can do also a redirect instead of exception
                return $this->redirect($this->generateUrl('homepage'));
            }

            // ...
        }
    }

正如这里和这里的文档所解释的
