PHP服務器無法找到真實的IP

Question

我正在運行一個Elastic Beanstalk環境，一個負載平衡器以及運行symfony2應用程序的實例。

我不能讓真正的訪問者的IP地址，$請求 - > getClientIP（）返回null，如果我將其設置爲信任代理在app.php，像這樣：

支持:: setTrustedProxies（陣列（$請求 - >服務器 - >的get（ 'REMOTE_ADDR'）））;

我得到奇怪的組播地址：

172.31.25.85

172.31.25.85

172.31.42.183

等。

這裏是我的SSL SSL終止。 conf

ProxyPass/http://localhost:80/ retry=0 
ProxyPassReverse/http://localhost:80/ 
ProxyPreserveHost on 
RequestHeader set X-Forwarded-Proto "https" early 

這裏是我的$ _ SERVER

您可以使用此功能，獲得真正的IP轉儲，有時$_SERVER["REMOTE_ADDR"]沒有表現出真正的IP所以需要定製，以獲得真正的IP。

function getRealIP() 
    { 
     if (isset($_SERVER["HTTP_CLIENT_IP"])) { 
      $ip = $_SERVER["HTTP_CLIENT_IP"]; 
     } elseif (isset($_SERVER["HTTP_X_FORWARDED_FOR"])) { 
      $ip = $_SERVER["HTTP_X_FORWARDED_FOR"]; 
     } elseif (isset($_SERVER["HTTP_X_FORWARDED"])) { 
      $ip = $_SERVER["HTTP_X_FORWARDED"]; 
     } elseif (isset($_SERVER["HTTP_FORWARDED_FOR"])) { 
      $ip = $_SERVER["HTTP_FORWARDED_FOR"]; 
     } elseif (isset($_SERVER["HTTP_FORWARDED"])) { 
      $ip = $_SERVER["HTTP_FORWARDED"]; 
     } else { 
      $ip = $_SERVER["REMOTE_ADDR"]; 
     } 

     // Strip any secondary IP etc from the IP address 
     if (strpos($ip, ',') > 0) { 
      $ip = substr($ip, 0, strpos($ip, ',')); 
     } 
     return $ip; 
    }
