Question

Is there a good way to call methods in SignalR hub from a controller ?

Right now I have this:

public class StatsHub : Hub
{
    private static readonly Lazy<StatsHub> instance = new Lazy<StatsHub>(() => new StatsHub());
    public static StatsHub Instance { get { return instance.Value; } }

    public StatsHub()
    {
        if (this.Clients == null)
        {
            var hubContext = SignalR.GlobalHost.ConnectionManager.GetHubContext<StatsHub>();
            this.Clients = hubContext.Clients;
            this.Groups = hubContext.Groups;
        }
    }

    // methods here...
}

so in my controller actions I can just say, for example

StatsHub.Instance.SendMessage("blah");

and it’s almost good, except that hubContext doesn’t have Caller or Context properties of Hub – which are nice to have.

Hopefully, there’s a better way to do this ?

Answer 1

Found a DefaultHubManager, which is what I need, I think.

DefaultHubManager hd = new DefaultHubManager(GlobalHost.DependencyResolver);
var hub = hd.ResolveHub("AdminHub") as AdminHub;
hub.SendMessage("woohoo");

Works. If there’s an even better/preferred way – please share.
