Dynamic Hubnames in Serverless SignalR Azure Functions #200

Open agravity-philipp opened 3 years ago

agravity-philipp commented 3 years ago

Hi, I managed to get an dynamic hubname for negotiation in an azure functions of this extension. But failed to have a dynamic SignalRTrigger-Hubname inside InvocationContext.

Is there a reason why this is not supported? https://github.com/Azure/azure-functions-signalrservice-extension/blob/e191a3011099049ceb6a3580a54ae2ec8dbbc2b6/src/SignalRServiceExtension/TriggerBindings/ServerlessHub.cs#L25

Or how can I use a traditional class model in an static Serverless SignalR binding like SignalRTrigger to change the listening to a specific hubName?

Does this make sense anyway if I can just have ONE upstream Azure Function per SignalR server who handles the trigger?

Apologies for my ignorance... hope someone can enlighten me.

ServerlessHub uses the same convention as SignalR SDK, the class name is the hub name. In SignalR, Hub can be considered as a high-level isolation, different hubs usually have different methods and different logics. However, negotiation logic usually the same for different hubs. Yes, can use traditional mode for SignalRTrigger. Please see https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-signalr-service-trigger?tabs=csharp#with-traditional-model

I can't get your point. You can of cause setup more than one trigger functions per function app.
