Azure-来自服务总线队列的触发器通知

Question

我正在尝试创建以下进程：

为了连接两端（IoT Hub和Notification Hub)，我尝试按照以下教程操作：https://www.developer.com/ws/android/senging-notifications-to-mobile-apps-fromon-azure-function-apps.html

此外，我还添加了从IoT集线器到服务总线中适当队列的路由。

现在，每当IoT设备向集线器发送消息时，我可以看到队列接收到消息。但是，我似乎不能使用队列来触发通知。

Error:

Function (ServiceBusQueueTrigger1) Error: The binding type(s) 'notificationHub' are not registered. Please ensure the type is correct and the binding extension is installed.

{
  "bindings": [
    {
      "name": "myQueueItem",
      "type": "serviceBusTrigger",
      "direction": "in",
      "queueName": "notificationqueue",
      "connection": "ServiceBusConnection",
      "accessRights": "manage"
    },
    {
      "name": "notification",
      "type": "notificationHub",
      "hubName": "<hub-name>",
      "connection": "NotificationConnString",
      "platform": "gcm",
      "tagExpression": "",
      "direction": "out"
    }
  ]
}

如何通过队列触发对android设备的通知？是否有一种方法可以直接从IoT Hub事件触发器函数触发它们？

谢了！

是的，您可以直接从传入的IoT Hub事件触发Azure函数。请参见我的一个示例:https://github.com/sebader/iotedge-end2end/blob/master/cloudfunctions/iothubmessageprocessor.cs

public static void Run([IoTHubTrigger("messages/events", Connection = "iothubevents_cs", ConsumerGroup = "receiverfunction")]EventData message, ILogger log)
{
  log.LogInformation($"IotHubMessageProcessor received a message: {Encoding.UTF8.GetString(message.Body.Array)}");
}
