SignalR send from Server console App to client












0















is it even possible to send a message to all(or selected) connected clients connected to the hub? I mean from the server side to all clients. I can get clients data to server window, but when I enter and try to send from server side nothing happens on clients window. How to push notifications to all straight from server app?



Server:



namespace SignalRHub
{


class Program
{
static void Main(string args)
{
string url = @"http://localhost:8080/";
using (WebApp.Start<Startup>(url))
{
Console.WriteLine(string.Format("Server running at {0}", url));
Console.ReadLine();

while (true)
{
// get text to send
Console.WriteLine("Enter your message:");
string line = Console.ReadLine();

// Get hub context
IHubContext ctx = GlobalHost.ConnectionManager.GetHubContext<TestHub>();

// call addMessage on all clients of context
ctx.Clients.All.addMessage(line);

// pause to allow clients to receive
Console.ReadLine();

}
}
}

class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseCors(CorsOptions.AllowAll);
app.MapSignalR();

}
}

[HubName("TestHub")]
public class TestHub : Hub
{
public void SendMsg(string message)
{
Console.WriteLine(message);
}
}

}
}


Client:



namespace SignalRClient
{
class Program
{
static void Main(string args)
{
IHubProxy _hub;

string url = @"http://localhost:8080/";
try
{
Console.WriteLine("Connecting to: " +url);

var connection = new HubConnection(url);
_hub = connection.CreateHubProxy("TestHub");
connection.Start().Wait();
Console.WriteLine();
Console.WriteLine();
Console.WriteLine("---------- Connection OK.");
Console.WriteLine();
}
catch (Exception e)
{
Console.WriteLine("------------ Connection FAILED: ");
Console.WriteLine(e);
throw;
}




string line = null;
while ((line = System.Console.ReadLine()) != null)
{
_hub.Invoke("SendMsg", line).Wait();
}

Console.Read();
}

}
}

  • Yes what you want to do is possible with SignalR. You need to add some code client-side that explicitly creates registers a callback for the Clients.All. call you have server-side. Something like: _hub.on('addMessage', function(line) { console.log(line); });

  • Thanks, as I understand client side has to be somehow subscribed to servers side method which pushes notifications? Could you please give a code example which I could use in actual client? Is this the only way or may be there is a way to force push to all of them like do "console.writeline("bla bla") to all clients", and then message appears in their console, they want it or not! possible?
