I have the following services implemented on Azure:
- 1x Azure SignalR Service (Serverless)
ASRS - 2x Azure Functions (Serverless)
HubFuncDown&HubFuncUp
On the ASRS I have defined TWO UpStream URLs, one to HubFuncDown Azure Function and the other to HubFuncUp. Using the URL pattern defined in the docs:
HubFuncDown Contains the following method which instructs the device app to disable itself:
[FunctionName(nameof(DisableDevice))]
public async Task DisableDevice([SignalRTrigger] InvocationContext invocationContext, string deviceId, ILogger logger) {
await Clients.User(deviceId).SendAsync(DisableDeviceTarget, new NewMessage(invocationContext, deviceId));
}
And HubFuncUp Contains the following method:
[FunctionName(nameof(DeviceDisabled))]
public async Task DeviceDisabled([SignalRTrigger] InvocationContext invocationContext, string deviceId, ILogger logger) {
// .. Updates DBContext, sends alerts etc
}
I'm trying to tell HubFuncUp that this client is now in a disabled state, the code to do that on the (UWP) client is:
var connection = new HubConnectionBuilder()
.WithUrl("https://hubfuncup.azurewebsites.net/api", options => {
options.AccessTokenProvider = () => Auth();
})
.ConfigureLogging(logging => {
logging.AddProvider(new SerilogLoggerProvider());
logging.SetMinimumLevel(LogLevel.Debug);
})
.WithAutomaticReconnect(new RetryPolicy())
.Build();
And to tell HubFuncUp of the state:
await connection.InvokeAsync("UpdateDeviceState", new DisabledDeviceMessage { DeviceId = 123, State = States.Disabled });
But each time I'm receiving a 404 Error from the call to InvokeAsync("UpdateDeviceState"..). It seems no matter what I do I cannot connect the one ASRS to two Azure Functions using multiple Upstream URLs.
Am I correct in thinking I need to utilise a seperate Azure SignalR Service (which doubles my cost) or can I connect the two Functions to the one SignalR Service via routing on the Upstream URLs?
