asp取真实IP的代码，搭环境测试无代理、一级或多级代理的情况，可以正常获取
asp函数代码：
复制代码 代码如下:
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
discuz论坛取真实IP的php代码，其它类似，请参考稍做修改
(discuz修改include/common.inc.php)
用以下这段代码:
复制代码 代码如下:
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')) {
$testip = explode('.', getenv('HTTP_X_FORWARDED_FOR'));
if ($testip[0]=='192′ && $testip[1]=='168′) {
$onlineip = getenv('REMOTE_ADDR');
}
elseif($testip[0]=='10′) {
$onlineip = getenv('REMOTE_ADDR');
}
else {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
}
//gamesir hack end} 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')) {
//by Johnny
$tmp_ip = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']);
$tmp_ip1 = explode(',',$tmp_ip[0]);
if ($tmp_ip1[0] =='192′ && $tmp_ip1[1] =='168′) {
$onlineip = getenv('REMOTE_ADDR');
}else if($tmp_ip1[0]=='10′) {
$onlineip = getenv('REMOTE_ADDR');
}
else{
$onlineip = $tmp_ip[0];
}
unset($tmp_ip);unset($tmp_ip1);
}
替换这段代码:
复制代码 代码如下:
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'];
}
