今天群里一个朋友在问这个问题。
查了下,CURL确实很强悍的可以伪造IP和来源。
1.php 请求 2.php 。
1.php代码:
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, ""); 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, " "); //构造来路 curl_setopt($ch, CURLOPT_HEADER, 1); $out = curl_exec($ch); curl_close($ch);2.php代码如下:
function getClientIp() { if (!empty($_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!!
