如何在 MVC 4 控制器中获取客户端 IP 地址？

Question

我试图在控制器中获取客户端 IP 地址。它正在工作，但有时我会收到此错误：

The underlying connection was closed: An unexpected error occurred on a receive


        String IP = "";

        using (WebResponse response = request.GetResponse())
        {
            using (StreamReader stream = new StreamReader(response.GetResponseStream()))
            {
                IP = stream.ReadToEnd();
            }
        }

        int first = IP.IndexOf("Address: ") + 9;
        int last = IP.LastIndexOf("</body>");
        IP = IP.Substring(first, last - first);

获取客户端IP地址有什么不同的方法吗？

Answer 1

尝试：

HttpContext.Request.UserHostAddress

Answer 2

这些都应该可以工作，从你的Controller:

方法一：

string userIpAddress = this.Request.ServerVariables["REMOTE_ADDR"];

方法二：

string userIpAddress = this.Request.UserHostAddress;

Answer 3

以下代码行帮助了我：

string ip = System.Web.HttpContext.Current.Request.UserHostAddress;
