LogicException：控制器必須返回一個響應（給出null）。你忘了在控制器的某個地方添加一個return語句嗎？

註銷後我想重定向到索引頁，但我得到一個錯誤的FOSUserBundleLogicException：控制器必須返回一個響應（給出null）。你忘了在控制器的某個地方添加一個return語句嗎？

在SecurityController.php

<?php 
     namespace ispg\Bundle\ChatBundle\Controller; 
     namespace FOS\UserBundle\Controller; 

     use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
     use Symfony\Component\DependencyInjection\ContainerAware; 
     use Symfony\Component\Security\Core\SecurityContext; 
     use Symfony\Component\Security\Core\Exception\AuthenticationException; 

class SecurityController extends ContainerAware 
{ 
    public function loginAction() 
    {   
      $request = $this->container->get('request'); 
      /* @var $request \Symfony\Component\HttpFoundation\Request */ 
      $session = $request->getSession(); 
      /* @var $session \Symfony\Component\HttpFoundation\Session */ 
      $network = $request->get("network"); 

      // get the error if any (works with forward and redirect -- see below) 
      if ($request->attributes->has(SecurityContext::AUTHENTICATION_ERROR)) { 
      $error = $request->attributes->get(SecurityContext::AUTHENTICATION_ERROR); 
      } elseif (null !== $session && $session->has(SecurityContext::AUTHENTICATION_ERROR)) { 
      $error = $session->get(SecurityContext::AUTHENTICATION_ERROR); 
      $session->remove(SecurityContext::AUTHENTICATION_ERROR); 
      } else { 
      $error = ''; 
      } 

      if ($error) { 
       // TODO: this is a potential security risk (see http://trac.symfony-project.org/ticket/9523) 
       $error = $error->getMessage(); 
      } 

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

      //create the select tag for network selection 
      require 'mnoNetworks.php'; 
      $selectHtml = "<select id=\"networks\"> 
         <option value=\"\"> -- Select -- </option>"; 

      foreach($networks as $network){ 
      $selectHtml .= "<option value=\"".$network."\">".$network."</option>"; 
      } 
      $selectHtml .="</select>"; 

      return $this->container->get('templating')->renderResponse('FOSUserBundle:Security:login.html.'.$this->container->getParameter('fos_user.template.engine'), array(
       'last_username' => $lastUsername, 
       'error'   => $error, 
       'network'  => $network, 
       'networkSelector' => $selectHtml 
      )); 
     } 

     public function checkAction() 
     { 
      throw new \RuntimeException('You must configure the check path to be handled by the firewall using form_login in your security firewall configuration.'); 
     } 

     public function logoutAction() 
     { 
      $bundle2 = new \ispg\Bundle\ChatBundle\Controller\DefaultController(); 
      $bundle2->setContainer($this->container); 
      $returned_data = $bundle2->san(); 
     } 
}

logoutAction會議後，我想重定向到索引頁
如何重定向到它。

任何人都可以解決這個問題嗎？

Jaitsu是正確的，它只是你的控制器擴展ContainerAware但提供快捷方式的基本控制器動作不控制器類...

return new Symfony\Component\HttpFoundation\RedirectResponse($this->generateUrl('name_of_route'));

其表示錯誤：致命錯誤：類 'FOS \ UserBundle \控制器\的Symfony \元器件\ HttpFoundation \ RedirectResponse' 不FO und in line 77上的/var/www/html/pan.ispghosting.com/phpver3/mno/vendor/bundles/FOS/UserBundle/Controller/SecurityController.php – Jethik

您需要呼叫重定向裏面你logoutAction() ...

return $this->redirect($this->generateUrl('name_of_route'));

致命錯誤：調用未定義方法FOS \ UserBundle \控制器\ SecurityController ::重定向（）在 – Jethik
