Question

我正在Symfony2中编写一个事件监听器，它监听kernel.response事件，并在以下情况下添加一个cookie：a）用户登录，b）当前不存在这样的cookie。它将服务容器作为参数。

但是，当侦听器响应不在防火墙后面的事件（例如开发工具栏中的事件）时，我收到错误，因为令牌为空并且抛出了AuthenticationCredentialsNotFoundException。但是，我不能为我的生活弄清楚如何判断路线是否在防火墙后面。有人可以帮忙吗？

代码

public function onKernelResponse(FilterResponseEvent $event) {
    // does the request have a device cookie?
    if ($this->container->get('security.authorization_checker')->isGranted('IS_AUTHENTICATED_FULLY')
        && !$this->getRequest()->cookies->has(DeviceManager::COOKIE_PREFIX.'id')) {
        // no. Create one.
        $DeviceManager          =   $this->container->get('salus_user.device_manager');
        $Cookie                 =   $DeviceManager->createDeviceCookie();
        $Response               =   $event->getResponse();
        $Response->headers->setCookie($Cookie); // and save it
    }
    // else, yes, we don't need to do anything
}

错误

AuthenticationCredentialsNotFoundException in classes.php line 2888:

The token storage contains no authentication token. One possible reason may be that there is no firewall configured for this URL.

首先检查是否存在令牌：

public function onKernelResponse(FilterResponseEvent $event) {
    if (!$this->container->get('security.token_storage')->getToken()) {
        return;
    }
    // Rest of code.
}

在Symfony2中判断路由是否在防火墙后面
