如果远程 ip C# httplistener 错误

Question

我创建了一个 httplistener，它只能使用 localhost 作为前缀。如果我将它更改为远程服务器 ip，它会显示错误。

代码如下:

 HttpListener listener = new HttpListener();
        listener.Prefixes.Add("http://*:8080/");  // I need localhost replaced with remote ip
        listener.Start();
        while (true)
        {
            // Wait for a client request:
            HttpListenerContext context = listener.GetContext();

            // Respond to the request:
            string msg = "You asked for: " + context.Request.RawUrl;
            context.Response.ContentLength64 = Encoding.UTF8.GetByteCount(msg);
            context.Response.StatusCode = (int)HttpStatusCode.OK;

            using (Stream s = context.Response.OutputStream)
            using (StreamWriter writer = new StreamWriter(s))
                writer.Write(msg);
        }
        listener.Stop();

这是网络客户端:

   using (WebClient wc = new WebClient())        // Make a client request.
                    wc.DownloadString
                      ("http://"my public ip"(on  my router):8080/lg.txt"); //port forwarding is set
                MessageBox.Show("received");

只有当我将“我的公共(public) ip”更改为我的本地 ip 时它才有效有什么想法吗？

您的 Windows 防火墙是否开启？尝试禁用它，看看是否有帮助。您可能需要实际禁用 Windows 防火墙服务(在您的本地服务列表中)。
