Question

请问ASP中如何获取客户端的ip地址？？

我用过网上的方法 但是 Request.ServerVariables("HTTP_X_FORWARDED_FOR") 返回值是空值
而Request.ServerVariables("REMOTE_ADDR") 的返回值是127.0.0.1
郁闷ing，还请大虾们赐教~

Answer 1

给你一个函数吧。
<%
'取得用户真实IP，对代理地址仍然有效；
Function GetUserTrueIP()
dim strIPAddr
If Request.ServerVariables("HTTP_X_FORWARDED_FOR") = "" OR InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), "unknown") > 0 Then
strIPAddr = Request.ServerVariables("REMOTE_ADDR")
ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",") > 0 Then
strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",")-1)
ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";") > 0 Then
strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";")-1)
Else
strIPAddr = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
End If
GetUserTrueIP = Trim(Mid(strIPAddr, 1, 30))
End Function
%>

Answer 2

就是用Request.ServerVariables("REMOTE_ADDR")这个，你获取的是127.0.0.1是因为你放在本地运行的，就是这个

Answer 3

127.0.0.1就是本机的ip地址啊

Answer 4

127.0.0.1不就是客户端IP?
