curl发出请求的文件fake_ip.php:
代码
复制代码 代码如下:
$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:
复制代码 代码如下:
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

CURL确实很强悍，可以伪造IP和来源。
1.php 请求 2.php 。
1.php代码：
复制代码 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, "http://www.jb51.net/ "); //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);
2.php代码如下：
复制代码 代码如下:
function getClientIp() {
if (!empty($_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"];
伪造成功，这是不是给“刷票”的朋友提供了很好的换IP的方案
