所以我有一个网站的加载页面,我在某个地方得到了一个脚本,它使用getipintel来查看用户是否在使用vpn。我想知道如何将其包含在我的加载页面中,这样当我的加载页第一次加载时,它就会运行php文件,如果用户有vpn,则清除页面并显示403拒绝访问
这是校验码http://pastebin.com/DXKmebvd
到目前为止,我已经尝试过:包括"check.php"需要"check.php"所有这些,我似乎无法让它工作
<?php
function checkProxy($ip){
$ip=$_SERVER['REMOTE_ADDR'];
global $ip;
$contactEmail="4horsemen@hitler.rocks"; //you must change this to your own email address
$timeout=5; //by default, wait no longer than 5 secs for a response
$banOnProability=0.99; //if getIPIntel returns a value higher than this, function returns true, set to 0.99 by default
//init and set cURL options
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
//if you're using custom flags (like flags=m), change the URL below
curl_setopt($ch, CURLOPT_URL, "http://check.getipintel.net/check.php?ip=$ip&contact=$contactEmail");
$response=curl_exec($ch);
curl_close($ch);
if ($response > $banOnProability) {
return true;
} else {
if ($response < 0 || strcmp($response, "") == 0 ) {
//The server returned an error, you might want to do something
//like write to a log file or email yourself
//This could be true due to an invalid input or you've exceeded
//the number of allowed queries. Figure out why this is happening
//because you aren't protected by the system anymore
//Leaving this section blank is dangerous because you assume
//that you're still protected, which is incorrect
//and you might think GetIPIntel isn't accurate anymore
//which is also incorrect.
//failure to implement error handling is bad for the both of us
}
return false;
}
}
$ip=$_SERVER['REMOTE_ADDR'];
if (checkProxy($ip)) {
/* A proxy has been detected based on your criteria
* Do whatever you want to here
*/
echo "[403 Forbidden Error] - Access Denied<br />";
}
?>
您无法通过PHP代码检测用户是否使用VPN服务。您只能在web浏览器设置中检测用户是否使用代理服务器,即使这样也无法一直检测到。您也可以检测TOR节点IP,但不是VPN!
