Supesite使用CDN后获取真实IP 办法

成都制作网页公司—include/main.inc.php文件,这部分

if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$_SGLOBAL['onlineip'] = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$_SGLOBAL['onlineip'] = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$_SGLOBAL['onlineip'] = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$_SGLOBAL['onlineip'] = $_SERVER['REMOTE_ADDR'];
}

替换成


function get_real_ip()
{
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
{
$ip = $_SERVER["HTTP_CLIENT_IP"];
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
if ($ip)
{
array_unshift($ips, $ip); $ip = FALSE;
}
for ($i = 0; $i < count($ips); $i++)
{
if (!eregi ("^(10|172\.16|192\.168)\.", $ips[$i]))
{
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
$_SGLOBAL['onlineip'] = get_real_ip();
Discuz!使用CDN后获取真实IP办法


nclude/common.inc.php
找到如下代码:


if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$onlineip = $_SERVER['REMOTE_ADDR'];
}

替换为:

 

function get_real_ip()
{
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
{
$ip = $_SERVER["HTTP_CLIENT_IP"];
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
if ($ip)
{
array_unshift($ips, $ip); $ip = FALSE;
}
for ($i = 0; $i < count($ips); $i++)
{
if (!eregi ("^(10|172\.16|192\.168)\.", $ips[$i]))
{
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
$onlineip = get_real_ip();

DZ注册用户IP和邀请码拥有者IP相同的解决办法

方法A:


register.php 200行

showmessage('register_invite_iperror');
改为
//showmessage('register_invite_iperror');

方法B:
在include/common.inc.php文件中把

代码:


if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$onlineip = $_SERVER['REMOTE_ADDR'];
}


替换成:

代码:
$onlineip=getenv('HTTP_X_FORWARD_FOR');

做了CDN的ASP网站如何取到用户真实IP程序


function   checkip(checkstring)'用正则判断IP是否合法
dim   re1
set   re1=new   RegExp
re1.pattern="^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}$"
re1.global=false
re1.Ignorecase=false
checkip=re1.test(checkstring)
set   re1=nothing
end   function


function   get_cli_ip()'取真实IP函数,先 HTTP_CLIENT_IP 再 HTTP_X_FORWARDED_FOR 再 REMOTE_ADDR
dim client_ip
if checkip(Request.ServerVariables("HTTP_CLIENT_IP"))=true then
         get_cli_ip = checkip(Request.ServerVariables("HTTP_CLIENT_IP"))
else
         MyArray = split(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),",")
         if ubound(MyArray)>=0 then
                   client_ip = trim(MyArray(0))
                   if checkip(client_ip)=true then
                            get_cli_ip = client_ip
                            exit function
                   end if
         end if
         get_cli_ip = Request.ServerVariables("REMOTE_ADDR")
end if
end   function


ASP.NET获取IP的6种方法
服务端:

//方法一
HttpContext.Current.Request.UserHostAddress;

//方法二
HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

//方法三
string strHostName = System.Net.Dns.GetHostName();
string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString();

//方法四(无视代理)
HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];


客户端:

//方法五
var ip = '{C}';
alert("Your IP address is "+ip);

//方法六(无视代理)
function GetLocalIPAddress()
{
    var obj = null;
    var rslt = "";
    try
    {
        obj = new ActiveXObject("rcbdyctl.Setting");
        rslt = obj.GetIPAddress;
        obj = null;
    }
    catch(e)
    {
        //
    }
    
    return rslt;
   }

来自印度的MCT Maulik Patel提供了一种服务端的解决方案,很好:

if(Context.Request.ServerVariables["HTTP_VIA"]!=null) // using proxy
{
     ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();  // Return real client IP.
}
else// not using proxy or can't get the Client IP
{
     ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString(); //While it can't get the Client IP, it will return proxy IP.
}

备注:
1. 有些代理是不会发给我们真实IP地址的
2. 有些客户端会因为“header_access deny”的安全设置而不发给我们IP
 

net的也可以参考http://www.cdnunion.com/articleinfo.php?pid=158设置
