PHP利用curl 伪造IP来源的解决办法

这篇文章主要为大家详细介绍了PHP利用curl 伪造IP来源的简单示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随php教程的小玲来看看吧！

curl发出请求的文件fake_ip.php:代码

代码如下:

 
<?php
/*   php教程 www.512Pic.com   */
 
$ch = curl_init(); 
$url = "http://localhost/target_ip.php"; 
$header = array( 
'CLIENT-IP:58.68.44.61', 
'X-FORWARDED-FOR:58.68.44.61', 
); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true); 
$page_content = curl_exec($ch); 
curl_close($ch); 
echo $page_content; 
?> 

代码如下:

 
<?php
/*   php教程 www.512Pic.com   */
 
echo getenv('HTTP_CLIENT_IP'); 
echo getenv('HTTP_X_FORWARDED_FOR'); 
echo getenv('REMOTE_ADDR'); 
?> 

代码如下:

 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php"); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //构造IP 
curl_setopt($ch, CURLOPT_REFERER, "https://www.idcnote.com/ "); //构造来路 
curl_setopt($ch, CURLOPT_HEADER, 1); 
$out = curl_exec($ch); 
curl_close($ch); 

代码如下:

 
function getClientIp() { 
if (!empty($_SERVER["HTTP_CLIENT_IP"])) 
$ip = $_SERVER["HTTP_CLIENT_IP"]; 
else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) 
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"]; 
else if (!empty($_SERVER["REMOTE_ADDR"])) 
$ip = $_SERVER["REMOTE_ADDR"]; 
else 
$ip = "err"; 
return $ip; 
} 
echo "IP: " . getClientIp() . ""; 
echo "referer: " . $_SERVER["HTTP_REFERER"];
