PHP如何使用CURL库进行IP欺骗，从而隐藏真实客户端IP

《PHP如何使用CURL库进行IP欺骗，从而隐藏真实客户端IP》要点：
本文介绍了PHP如何使用CURL库进行IP欺骗，从而隐藏真实客户端IP，希望对您有用。如果有疑问，可以联系我们。

首先搭建环境，建立个ip.php.

<?

error_reporting(0);

function GetIP(){

if($_SERVER['HTTP_CLIENT_IP']){

   $onlineip=$_SERVER['HTTP_CLIENT_IP'];

   }elseif($_SERVER['HTTP_X_FORWARDED_FOR']){

   $onlineip=$_SERVER['HTTP_X_FORWARDED_FOR'];

   }else{

   $onlineip=$_SERVER['REMOTE_ADDR'];

   }

return $onlineip;

}

?>

再建立个index.php

<?php

error_reporting(0);

require 'ip.php';

echo '<hr>'.'Your IP is '.GetIP().'<br>'.'<hr>';

/*echo 'REMOTE_ADDR is '.$_SERVER['REMOTE_ADDR'].'<br>';

echo 'HTTP_CLIENT_IP is  '.$_SERVER['HTTP_CLIENT_IP'].'<br>';

echo 'HTTP_X_FORWARDED_FOR is '.$_SERVER['HTTP_X_FORWARDED_FOR'].'<br>';

echo 'HTTP_VIA is '.$_SERVER['HTTP_VIA'];*/

?>

测试:

IP显示正确,客户端真实IP是218.241.179.50

去掉index.php里面的注释，使用代理观察

可以看到REMOTE_ADDR方法抓到了代理IP

HTTP_XFORWARDED_FOR还是抓到了客户端的真实IP

接下来编辑curl_proxy.php,示例代码：

<?php

error_reporting(0);

function curl_string ($url,$user_agent,$proxy){

$ch = curl_init();

curl_setopt ($ch, CURLOPT_PROXY, $proxy);

curl_setopt ($ch, CURLOPT_URL, $url);

curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);

curl_setopt ($ch, CURLOPT_COOKIEJAR, "d:\cookies.txt");

curl_setopt ($ch, CURLOPT_HEADER, 1);

curl_setopt ($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP:125.210.188.36', 'X-FORWARDED-FOR:125.210.188.36'));  //此处可以改为任意假IP

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt ($ch, CURLOPT_TIMEOUT, 120);

$result = curl_exec ($ch);

curl_close($ch);

return $result;

}

$url_page = "http://s4nd.no-ip.org/test/index.php";

$user_agent = "Mozilla/4.0";

$proxy = "http://125.210.188.36:80";    //此处为代理服务器IP和PORT

$string = curl_string($url_page,$user_agent,$proxy);

echo $string;

?>

访问curl_proxy.php

122.66.*.*是运行脚本服务器的IP，这样就实现了隐藏客户端真实IP的目的。

有的代理服务器会被HTTP_VIA方法侦测到使用了代理服务器，实际上透明代理和高级匿名代理有很大区别。
