使用CDN后，获取真实IP办法 (127.0.0.1)
虚拟主机登录会员或登录后台管理,一般都会获取用户客户端地址并记录数据库.但相同程序部署我司虚拟主机后,获取客户端地址不是用户真实ip地址或为 "127.0.0.1",可以通过以下方式修改获取客户ip地址部分代码解决.

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(!preg_match("/^(10|172\.16|192\.168)\./", $ $ips[$i])){
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
$_SGLOBAL['onlineip'] = get_real_ip();

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')) {

} 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"];
}

帝国cms后台记录的ip日志和用户注册记录的ip
\e\class\connect.php搜索function egetip()函数中的获取ip代码修改成以上部分
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 = '<!--#echo var="REMOTE_ADDR"-->';
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
