復制代碼 代碼如下: function checkip(checkstring)'用正則判斷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
復制代碼 代碼如下: function get_cli_ip()'取真實IP函數，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
