php curl 偽造IP來源的實例代碼
Jun 13, 2016 am 11:57 AM
curl發(fā)出請求的文件fake_ip.php:
代碼
復制代碼 代碼如下:
$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;
?>
請求的目標文件target_ip.php:
復制代碼 代碼如下:
echo getenv('HTTP_CLIENT_IP');
echo getenv('HTTP_X_FORWARDED_FOR');
echo getenv('REMOTE_ADDR');
?>
目標文件target_ip里面的IP打印順序是目前很多開源系統(tǒng)的IP獲取順序
訪問fake_ip.php,看到結(jié)果:
58.68.44.61
58.68.44.61
127.0.0.1
實例
CURL確實很強悍，可以偽造IP和來源。
1.php 請求 2.php 。
1.php代碼：
復制代碼 代碼如下:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //構造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.jb51.net/ "); //構造來路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);
2.php代碼如下：
復制代碼 代碼如下:
function getClientIp() {
if (!empty($_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"];
偽造成功，這是不是給“刷票”的朋友提供了很好的換IP的方案
