Symfony 2:如果用户具有特定角色，则将用户重定向到页面 [英] Symfony 2 : Redirect a user to a page if he has a specific role

问题描述

我有一个小问题.我希望用户在我网站上的任何位置，如果他有ROLE_DEGRADE"角色，他就会被重定向到特定页面.

I have a little question. I want that wherever is the user on my website, if he have the role "ROLE_DEGRADE", he is redirected on a specific page.

我该怎么做，我必须使用防火墙?我不想将用户重定向到表单登录，只是重定向到一个简单的页面.我希望在我的网站上随处可见，不要在我的所有控制器中随处放置如果角色降级..."...

How I can do that, I have to use firewall ? I don't want to redirect the user to a form login, just to a simple page. I want that everywhere on my website, without put a "if role degrade..." everywhere, in all my controllers...

感谢您的帮助;)

推荐答案

这样的事情应该可以...

Something like this should do it ...

创建一个新的监听器:

class AccessListener
{
    private$security;
    private $router;

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

    public function onKernelRequest(GetResponseEvent $event)
    {
        if ($this->security->isGranted('ROLE_DEGRADE')) {
           $url = $this->router->generate('<route name>');
           $event->setResponse(new RedirectResponse($url));
        }
    }
}

将其添加到您的 services.yml :

services:
  access_listener:
    class: AcmeDemoBundleListenerAccessListener
    arguments: [ @security.context, @router ]
    tags:
      - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
