使用Azure函数将多个代理消息输出到Azure服务总线主题

Question

Is there a way you output multiple Brokered Messages to an Azure Service Bus in Azure Functions? by default you can output a single Brokered Message but not multiple.

Currently using the SDK to do this but wondered if there is a way you can do this using the output...

Thanks

Answer 1

As per the documentation on ServiceBus output bindings:

For creating multiple messages in a C# function, you can use ICollector<T> or IAsyncCollector<T> . A message is created when you call the Add method.

Here is a simple example of using ICollector (also directly from the docs):

public static void Run(TimerInfo myTimer, TraceWriter log, ICollector<string> outputSbQueue)
{
    string message = $"Service Bus queue message created at: {DateTime.Now}";
    log.Info(message); 
    outputSbQueue.Add("1 " + message);
    outputSbQueue.Add("2 " + message);
}

I personally find that all of the supported input/output bindings are well documented and examples are readily available at the link I've shown here. Just pick the appropriate binding you're working with (if it's something other than Service Bus)

Also, Functions is built on top of the WebJobs SDK; so if you can do a binding in the SDK, you can do the same thing in Functions (with a few corner case exceptions).
