如何在Azure函数中动态绑定服务总线BrokeredMessage

Question

我正在使用具有天蓝色功能的服务总线。 该函数由队列触发，然后将输入BrokeredMessage上的ReplyTo属性用作要响应的队列。 如何动态绑定到输出队列？ 我试过下面的代码，但得到：

无法将ServiceBus绑定为“ Microsoft.ServiceBus.Messaging.BrokeredMessage”类型。

public static async Task Run(BrokeredMessage msg, Binder binder, TraceWriter log)
{
    log.Info($"C# ServiceBus queue trigger function processed message");
    var msgout = await binder.BindAsync<BrokeredMessage>(new ServiceBusAttribute(msg.ReplyTo));
}

function.json

{
  "disabled": false,
  "bindings": [
    {
      "name": "msg",
      "type": "serviceBusTrigger",
      "direction": "in",
      "queueName": "myInputQueue",
      "connection": "AzureWebJobsServiceBus",
      "accessRights": "Manage"
    }
  ]
}

对于输出方案，您需要绑定到IAsyncCollector类型：

public static async Task Run(
    BrokeredMessage msg, Binder binder, TraceWriter log)
{
    log.Info($"C# ServiceBus queue trigger function processed message");
    var collector = await binder.BindAsync<IAsyncCollector<BrokeredMessage>>(
                        new ServiceBusAttribute(msg.ReplyTo));

    var message = ...
    await collector.AddAsync(message);
}
