How can I call a hub method from a controller's action? What is the correct way of doing this?
Someone used this in a post:
DefaultHubManager hd = new DefaultHubManager(GlobalHost.DependencyResolver);
var hub = hd.ResolveHub("AdminHub") as AdminHub;
hub.SendMessage("woohoo");
But for me, that is throwing:
Using a Hub instance not created by the HubPipeline is unsupported.
I've read also that you can create a hub context, but I don't want to give the responsability to the action, that is, the action doing stuff like:
hubContext.Client(...).someJsMethod(..)
The correct way is to actually create the hub context. How and where you do that is up to you, here are two approachs:
Create a static method in your hub (doesn't have to be in your hub, could actually be anywhere) and then you can just call it via AdminHub.SendMessage("wooo")
public static void SendMessage(string msg)
{
var hubContext = GlobalHost.ConnectionManager.GetHubContext<AdminHub>();
hubContext.Clients.All.foo(msg);
}
Avoid the static method all together and just send directly to the hubs clients
var hubContext = GlobalHost.ConnectionManager.GetHubContext<AdminHub>();
hubContext.Clients.All.foo(msg);
