php如何使用curl伪造IP来源的方法
php如何使用curl伪造IP来源<?php <br />
<br>
$ch = curl_init();<br>
<br>
$url = "http://localhost/target_ip.php";<br>
<br>
$header = array('CLIENT-IP:58.68.44.61','X-FORWARDED-FOR:58.68.44.61',);<br>
<br>
curl_setopt($ch, CURLOPT_URL, $url);<br>
<br>
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);<br>
<br>
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);<br>
<br>
$page_content = curl_exec($ch);curl_close($ch);<br>
<br>
echo $page_content;<br>
<br>
?>请求的目标文件---target_ip.php:<?php <br />
<br>
echo getenv('HTTP_CLIENT_IP');<br>
<br>
echo getenv('HTTP_X_FORWARDED_FOR');<br>
<br>
echo getenv('REMOTE_ADDR');<br>
<br>
?>目标文件target_ip里面的IP打印顺序是目前很多开源系统的IP获取顺序 访问fake_ip.php,看到结果: 58.68.44.61
58.68.44.61 127.0.0.1
最后，为大家提供二个小例子。 例1: <?php <br />
<br>
$ch = curl_init();<br>
<br>
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");<br>
<br>
curl_setopt($ch, CURLOPT_HTTPHEADER, <br>
array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //构造<br>
<br>
IPcurl_setopt($ch, CURLOPT_REFERER, "http://bbs.it-home.org/ "); //构造来路<br>
<br>
curl_setopt($ch, CURLOPT_HEADER, 1);<br>
<br>
$out = curl_exec($ch);curl_close($ch);<br>
<br>
?>例2： <?php <br />
<br>
function getClientIp() {<br>
<br>
if (!empty($_SERVER["HTTP_CLIENT_IP"]))<br>
<br>
$ip = $_SERVER["HTTP_CLIENT_IP"];<br>
<br>
else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))<br>
<br>
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];<br>
<br>
else if (!empty($_SERVER["REMOTE_ADDR"]))<br>
<br>
$ip = $_SERVER["REMOTE_ADDR"];<br>
<br>
else$ip = "err";<br>
<br>
return $ip;<br>
<br>
}<br>
<br>
echo "IP: " . getClientIp() . "";<br>
<br>
echo "referer: " . $_SERVER["HTTP_REFERER"];<br>
