php - $_SERVER ['REMOTE_ADDR' ] 返回 127.0.0.1

Question

$_SERVER['REMOTE_ADDR'] 返回 127.0.0.1。

那是因为我安装了 varnish 缓存，数据转到 varnish，然后是 apache，服务器认为请求来自 varnish 而不是客户端？

Answer 1

像这样获取远程ip地址:

public function getRemoteIPAddress() {
    if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
        return $_SERVER['HTTP_CLIENT_IP'];

    } else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { 
        return $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    return $_SERVER['REMOTE_ADDR'];
}
