无法从Xamarin.Forms应用连接到SignalR服务器

Question

Here's my environment:

• Visual Studio 2017 15.1, running on Windows 10, which runs in VM on MacOSX.
• In VS I installed API23 Android SDK.
• On MacOSX: Xamarin Studio 6.3
• Both, XS on Mac and VS on Windows have Xamarin.iOS 10.8.0.175

I have one solution where I implemented signalR server. It's a simple chat server. It works. It's running on the windows VM. I tried connecting and sending message from my mac (so technically a separate computer in the network) and it works!

Now, I'm trying to consume it from Xamarin.Forms iOS and Droid projects.. without any success. In PCL 's App class I have:

    protected override void OnStart()
    {
        // Handle when your app starts
        try
        {
            var hubConnection = new HubConnection("10.0.1.58:49919");
            var chatHubProxy = hubConnection.CreateHubProxy("ChatHub");

            hubConnection.Start();
        }
        catch (Exception ex)
        {
            // System.UriFormatException: Invalid URI: The URI scheme is not valid.

        }
    }

System.UriFormatException: Invalid URI: The URI scheme is not valid.

What am I doing wrong?

Answer 1

Try a http:// prefix and another thing to try is to end a trailing slash.

So try combinations of:

new HubConnection("http://10.0.1.58:49919");

new HubConnection("http://10.0.1.58:49919/");

new HubConnection("10.0.1.58:49919/");
