第二篇：nat123端口映射获取客户端访问真实用户IP方法
内网地址经过代理或NAT端口映射后，获取到的IP都是映射的那个转发IP，客户端访问的真正用户IP丢失了，怎么弄？怎么才能获取得到客户端访问真实用户IP？
解决方法：通过nat123端口映射处理，获取客户端真正用户IP。
Nat123自带客户端IP转发，只需要在对应应用程序中配置好相关参数即可。
参数配置都是按照.NET、PHP、DISCUZ标准设置，详细实现方法如下：
1. asp.net获取方法为：
string ip = Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
2.PHP获取用户真实IP方法为：$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
3.discuz论坛获取的具体方法为：
解决方法（Discuz x2.5至Discuz x3.1），其它版本如需知道请回复或者开新帖询问 打开文件\source\class\discuz\discuz_application.php 找到如下代码：
把函数
private function _get_client_ip() {
$ip = $_SERVER['REMOTE_ADDR'];
if (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}\.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR']) AND preg_match_all('#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#s',
$_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) {
foreach ($matches[0] AS $xip) {
if (!preg_match('#^(10|172\.16|192\.168)\.#', $xip)) {
$ip = $xip;
break;
}
}
}
return $ip;
}
修改成:
private function _get_client_ip() {
$ip = $_SERVER['REMOTE_ADDR'];
if (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}\.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR']) AND preg_match_all('#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#s',
$_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) {
foreach ($matches[0] AS $xip) {
if (!preg_match('#^(10|172\.16|192\.168)\.#', $xip)) {
$ip = $xip;
break;
}
}
}
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']) &&
preg_match('/^([0-9]{1,3}\.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
return $ip;
}
