做了CDN加速的ASP网站获取用户真实IP程序
2018-09-06 12:28
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
复制代码 代码如下:
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
