局域网上的SignalR托管

Question

我正在开发winform应用程序。它正在两台计算机上工作。安装在主（主机）计算机上的MSSQLSERVER。该程序可以在主计算机上正常运行。

我有一个SignalR服务器（Windows窗体），该服务器托管在IP为（192.168.1.5）的计算机上

但是，当我放置该IP地址时，程序无法正常工作。为什么总是在本地主机上工作？

    public partial class WinFormsClient : Form
{
    /// <summary>
    /// This name is simply added to sent messages to identify the user; this 
    /// sample does not include authentication.
    /// </summary>
    private String UserName { get; set; }
    private IHubProxy HubProxy { get; set; }

    const string ServerURI = "http://localhost:1313/signalr";
    private HubConnection Connection { get; set; }

    internal WinFormsClient()
    {
        InitializeComponent();
    }

    private void ButtonSend_Click(object sender, EventArgs e)
    {
        HubProxy.Invoke("Send", UserName, TextBoxMessage.Text);
        TextBoxMessage.Text = String.Empty;
        TextBoxMessage.Focus();
    }

    /// <summary>
    /// Creates and connects the hub connection and hub proxy. This method
    /// is called asynchronously from SignInButton_Click.
    /// </summary>
    private async void ConnectAsync()
    {


        Connection = new HubConnection(ServerURI);
        Connection.Closed += Connection_Closed;
        HubProxy = Connection.CreateHubProxy("MyHub");
        //Handle incoming event from server: use Invoke to write to console from SignalR's thread
        HubProxy.On<string, string>("AddMessage", (name, message) =>
            this.Invoke((Action)(() =>
                RichTextBoxConsole.AppendText(String.Format("{0}: {1}" + Environment.NewLine, name, message))
            ))
        );

        HubProxy.On<string>("CallForReport", (message) =>
                this.Invoke((Action)(() =>
                    RichTextBoxConsole.AppendText(String.Format("{0}" + Environment.NewLine, message))
            ))
        );

        try
        {
            await Connection.Start();
        }
        catch (HttpRequestException)
        {
            StatusText.Text = "Unable to connect to server: Start server before connecting clients.";
            //No connection: Don't enable Send button or show chat UI
            return;
        }

        //Activate UI
        SignInPanel.Visible = false;
        ChatPanel.Visible = true;
        ButtonSend.Enabled = true;
        TextBoxMessage.Focus();
        RichTextBoxConsole.AppendText("Connected to server at " + ServerURI + Environment.NewLine);
    }

    /// <summary>
    /// If the server is stopped, the connection will time out after 30 seconds (default), and the 
    /// Closed event will fire.
    /// </summary>
    private void Connection_Closed()
    {
        //Deactivate chat UI; show login UI. 
        this.Invoke((Action)(() => ChatPanel.Visible = false));
        this.Invoke((Action)(() => ButtonSend.Enabled = false));
        this.Invoke((Action)(() => StatusText.Text = "You have been disconnected."));
        this.Invoke((Action)(() => SignInPanel.Visible = true));
    }

    private void SignInButton_Click(object sender, EventArgs e)
    {
        UserName = UserNameTextBox.Text;
        //Connect to server (use async method to avoid blocking UI thread)
        if (!String.IsNullOrEmpty(UserName))
        {
            StatusText.Visible = true;
            StatusText.Text = "Connecting to server...";
            ConnectAsync();
        }
    }

    private void WinFormsClient_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (Connection != null)
        {
            Connection.Stop();
            Connection.Dispose();
        }
    }
}

我想将localhost更改为（192.168.1.5:1313） 之后，我想从客户端到服务器接收消息。

客户端1 IP为（192.168.1.5） 客户端2的IP为（192.168.1.20）

同一台计算机上的SignlaR Hub + MSSQLSERVER + Client1。
