Question

我正在运行带有负载均衡器的Elastic Beanstalk环境，以及运行symfony2应用程序的实例。

我无法获得真实的访问者IP地址，$ request-＆gt; getClientIP（）返回null，如果我将其设置为app.php中的信任代理，如下所示：

支持:: setTrustedProxies（阵列（$请求 - ＆GT;服务器 - ＆GT;获得（ 'REMOTE_ADDR'）））;

我得到了奇怪的多播地址：

172.31.25.85

172.31.42.183

等。

这是我在ssl.conf中的SSL终止

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

这是我的$ _SERVER转储

您可以使用此功能获取真正的IP，有时$_SERVER["REMOTE_ADDR"]不显示真正的IP，因此需要自定义以获得真正的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;
    }

PHP Server无法找到真正的IP
