Question

我已经尝试了下面解释的内容，不知何故，IP地址始终是:: 1，在本地和服务器端，

以下是我试过的代码;

m_CallerIP = string.IsNullOrEmpty(req.ServerVariables["HTTP_CLIENT_IP"]) ? req.UserHostAddress : req.ServerVariables["HTTP_CLIENT_IP"];
string Port = string.IsNullOrEmpty(req.ServerVariables["HTTP_CLIENTPORT"]) ? req["HTTP_CLIENTPORT"] : req.ServerVariables["CLIENTPORT"];

string asd2 = String.IsNullOrEmpty(req.ServerVariables["REMOTE_ADDR"]) ? req.UserHostAddress : req.ServerVariables["REMOTE_ADDR"];
string asd23 = String.IsNullOrEmpty(req.ServerVariables["HTTP_X_FORWARDED_FOR"]) ? req.UserHostAddress : req.ServerVariables["HTTP_X_FORWARDED_FOR"];

string asd4 = req.UserHostAddress;

IPAddress address = IPAddress.Parse(m_CallerIP);
IPAddress address1 = IPAddress.Parse(asd2);
IPAddress address2 = IPAddress.Parse(asd23);
IPAddress address3 = IPAddress.Parse(asd4);

有没有人知道为什么以及如何解决它？

提前致谢！

下面的代码对我有用。

当我在localhost中运行应用程序时，我总是得到:: 1。但是，它在服务器端很有用。该应用程序在Azure中运行。

string ip = "";

ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

if (!string.IsNullOrEmpty(ip))
    ip = ip.Split(',').Last().Trim();
else
    ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

if (ip == "::1")
    ip = "";

if (ip.IndexOf(':') > 0)
    ip = ip.Substring(0, ip.IndexOf(':'));

return ip;

C＃IP地址始终:: 1
