Question

我在服务器的同一目录中有两个php文件（http://www.xxxx.com/php/），

1） write_json.php



    $address['http_client'] = $_SERVER['HTTP_CLIENT_IP'];
    $address['http_x_forwarded_for'] = $_SERVER['HTTP_X_FORWARDED_FOR'];
    $address['http_x_forwarded'] = $_SERVER['HTTP_X_FORWARDED'];
    $address['http_forwarded_for'] = $_SERVER['HTTP_FORWARDED_FOR'];
    $address['http_forwarded'] = $_SERVER['HTTP_FORWARDED'];
    $address['remote_addr'] = $_SERVER['REMOTE_ADDR'];

    header('Content-Type: application/json');
    echo json_encode($address);

2） get_ip.php

    $json_url = $_SERVER['SERVER_NAME'] . '/php/write_json.php';

    $json_string = '';
    $ch = curl_init($json_url);


    $options = array(CURLOPT_RETURNTRANSFER => true, 
                         CURLOPT_HTTPHEADER => array('Content-type: application/json'), 
                         CURLOPT_POSTFIELDS => $json_string);

    curl_setopt_array($ch, $options);

    $json_string =  curl_exec($ch);
    echo $json_string;

get_ip.php 调用 write_json.php

如果我们假设客户端IP是： 76.2.35.46 而服务器IP是： 80.59.3.23
当我在客户端浏览器上调用http://www.xxxx.com/php/get_ip.php时

它向我显示服务器IP而非客户端IP，如下所示：

{
    http_client: null,
    http_x_forwarded_for: null,
    http_x_forwarded: null,
    http_forwarded_for: null,
    http_forwarded: null,
    remote_addr: "80.59.3.23"
}

如何获取客户端IP而不是服务器IP？

Answer 1

您正在通过curl从服务器调用write_json ...也就是说，服务器实际上正在请求write_json文件，因此write_json看到请求来自服务器。为什么不使用包含而不是卷曲调用？

Answer 2

这种方式不可能。您需要首先获取客户端IP，然后通过curl将其作为发布的数据发送到服务器。

Answer 3

尝试使用以下将返回客户端IP的函数来使用客户端IP

// Function to get the client IP address
function get_client_ip() {
    $ipaddress = '';
    if (getenv('HTTP_CLIENT_IP'))
        $ipaddress = getenv('HTTP_CLIENT_IP');
   else if(getenv('HTTP_X_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
   else if(getenv('HTTP_X_FORWARDED'))
        $ipaddress = getenv('HTTP_X_FORWARDED');
   else if(getenv('HTTP_FORWARDED_FOR'))
       $ipaddress = getenv('HTTP_FORWARDED_FOR');
   else if(getenv('HTTP_FORWARDED'))
       $ipaddress = getenv('HTTP_FORWARDED');
   else if(getenv('REMOTE_ADDR'))
       $ipaddress = getenv('REMOTE_ADDR');
   else
       $ipaddress = 'UNKNOWN';
   return $ipaddress;
}

在变量中获取IP后，发送

php，获取客户端IP地址
