爲什麼控制器方法在symfony2中被調用兩次

Question

我遇到了一個問題，我的控制器操作被調用兩次，我不知道爲什麼。

這是我爲測試所做的一個簡單方法。

/** 
    * @param Request $request 
    * @return Response 
    * @Route("/star-remote-control") 
    */ 
    public function starRemoteControlAction(Request $request) 
    { 
    $this->container->get('monolog.logger.always')->info('ClientIP:' . $request->getClientIp() . ' ' . $request->getContent()); 

    return new Response("hello"); 
    } 

這裏是日誌。

你能幫我解決爲什麼它叫了兩聲？

在此先感謝

Answer 1

我不女巫服務使用，因爲默認情況下訪問獨白與記錄器服務，也許你對「monolog.logger」使服務和服務正在兩倍登錄到該文件。

我使用這個代碼能夠正確的工作：

$logger = $this->get('logger'); 
$logger->info('ClientIP:' . $request->getClientIp() . ' ' . $request->getContent()); 

我的日誌：

[2017-01-23 16:23:59] event.DEBUG: Notified event "kernel.controller" to listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener::onKernelController". [] []

[2017-01-23 16:23:59] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Component\Security\Http\RememberMe\ResponseListener::onKernelResponse". [] [] 

的獨白服務是這樣的：
