azure function service bus output message properties

Question

I'm trying to set metadata for service bus messages in a JavaScript Azure Function using the service bus binding output. Unfortunately, it appears that the binding only supports the body.

Looking at the docs, I see that you can access this information in service bus triggers via context.bindingData but I don't see any corresponding interface for service bus output.

Is there some way to send a full brokered message and set the message properties (ContentType) and message custom properties?

My workaround: https://stackoverflow.com/questions/48338448/sending-message-to-azure-service-bus-as-a-string-using-azure-logic-app/53013123#53013123 — tonjohn, Aug 07 '19 at 00:45

@l--''''''---------'''''''''''' You need to access the Microsoft.Azure.ServiceBus.Message class. Let's say you have some json called messageBody

and you have some list of properties that you want to add to the message. You can achive it like the below example.

Make sure you add using Microsoft.Azure.ServiceBus;

var myCustomProperties = new List<Dictionary<string,string>>();
var message = new Message(Encoding.UTF8.GetBytes(messageBody));
foreach (var userProperty in myCustomProperties)
{
  message.UserProperties.Add(userProperty.Key, userProperty.Value);
}

any reason not to use `Parallel.ForEach` ? – Alex Gordon Aug 11 '19 at 04:42
You can use that as well – HariHaran Aug 12 '19 at 04:29

There is an open issue for this at https://github.com/Azure/Azure-Functions/issues/454

Some customers seemed to have found a workaround. Perhaps you can try their approach mentioned here https://github.com/Azure/Azure-Functions/issues/454#issuecomment-375154151
