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
$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;
?>
请求的目标文件---target_ip.php:
<?php
echo getenv('HTTP_CLIENT_IP');
echo getenv('HTTP_X_FORWARDED_FOR');
echo getenv('REMOTE_ADDR');
?>
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
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
curl_setopt($ch, CURLOPT_HTTPHEADER,
array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //构造
IPcurl_setopt($ch, CURLOPT_REFERER, "http://bbs.it-home.org/ "); //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);curl_close($ch);
?>
例2:
<?php
function getClientIp() {
if (!empty($_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"];
?>
