Taken from: http://docs.autofac.org/en/latest/integration/signalr.html:
"A common error in OWIN integration is use of the GlobalHost. In OWIN you create the configuration from scratch. You should not reference GlobalHost anywhere when using the OWIN integration."
That sounds reasonable. However, how should one resolve IHubContext
from an ApiController, like the usual (non-OWIN):
GlobalHost.ConnectionManager.GetHubContext<MyHub>()
?
I can't find a reference on this one anywhere, and the only method I have by now is to register the HubConfiguration
instance within the same container and do this:
public MyApiController : ApiController {
public HubConfiguration HubConfig { get; set; } // Dependency injected by
// PropertiesAutowired()
public IHubContext MyHubContext {
get {
return HubConfig
.Resolver
.Resolve<IConnectionManager>()
.GetHubContext<MyHub>();
}
}
// ...
}
However, this seems quite verbose to me. What is the proper way to do it? To be more specific, is there a clean way to register IConnectionManager
?
EDIT:
What I ended up doing is something like:
var container = builder.Build();
hubConfig.Resolver = new AutofacDependencyResolver(container);
app.MapSignalR("/signalr", hubConfig);
var builder2 = new ContainerBuilder();
builder2
.Register(ctx => hubConfig.Resolver.Resolve<IConnectionManager>())
.As<IConnectionManager>();
builder2.Update(container);
but I have a feeling there must be an easier way to get that IConnectionManager
injected in the controller.
