RedirectionListener.php中的FatalErrorException第46行：錯誤：調用非對象的成員函數getUser（）

Question

我遇到了FOSUserBundle問題。

我有一個重定向偵聽器，以防止用戶使用的應用程序沒有被登錄，下面的代碼：

class RedirectionListener 
{ 
    /** 
    * RedirectionListener constructor. 
    * @param ContainerInterface $container 
    * @throws \Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException 
    * @throws \Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException 
    */ 
    public function __construct(ContainerInterface $container) 
    { 
     $this->router = $container->get('router'); 
     $this->securityTokenStorage = $container->get('security.token_storage'); 
    } 

    /** 
    * @param GetResponseEvent $event 
    * @throws \InvalidArgumentException 
    */ 
    public function onKernelRequest(GetResponseEvent $event){ 

    $route = $event->getRequest()->attributes->get('_route'); 

    if($route !== 'fos_user_security_login' && 
     $route !== 'fos_user_resetting_reset' && 
     $route !== 'fos_user_resetting_request' && 
     $route !== 'fos_user_resetting_send_email' && 
     $route !== 'fos_user_resetting_check_email' && 
     $route !== 'fos_user_change_password' && 
     !is_object($this->securityTokenStorage->getToken()->getUser())) //this is line 46 
     { 
     $event->setResponse(new RedirectResponse($this->router->generate('fos_user_security_login'))); 
     } 
    } 
} 

這是我的服務：

services: 
redirectonListener: 
    class: Projects\ProjectsBundle\Listener\RedirectionListener 
    arguments: ['@service_container'] 
    tags: 
     - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest } 

而且這裏離我的防火牆設置FOSUserBundle Docs：

firewalls: 
    # disables authentication for assets and the profiler, adapt it according to your needs 
    dev: 
     pattern: ^/(_(profiler|wdt)|css|images|js)/ 
     security: false 

    main: 
     pattern: ^/ 
     form_login: 
      provider: fos_userbundle 
      csrf_token_generator: security.csrf.token_manager 
      # if you are using Symfony < 2.8, use the following config instead: 
      # csrf_provider: form.csrf_provider 

     logout:  true 
     anonymous: true 

我正在使用Symfony 2.8版本。誰能幫忙！

Answer 1

您是否嘗試在security.yml中設置access_control？

例如：

security: 
    #[...] 

    access_control: 
     - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY } 
     - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY } 
     - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY } 
     # and so on, until: 
     - { path: ^/restricted, role: ROLE_USER } 
     # or: 
     - { path: ^/*, role: IS_AUTHENTICATED_ANONYMOUSLY }

編輯：不要忘記清除緩存的變化作出後。

我只是給你一個例子，以便你可以修改它以滿足你的需求。除了聽衆這樣做的方式之外，你應該看看FOS中的security.yml方法。有很多例子。例如，在http://www.inanzzz.com/中搜索access_control，這會給你6個例子來研究一下。

注意：切勿將整個容器注入爲服務參數！

一些例子。

• Overriding controller response message with an even listener in symfony
• Testing onKernelController event listener for user requests with phpspec in symfony
