如何使用Azure Notification Hubs从事件中心接收消息并转发到android应用程序？

Question

I want to receive messages from an event hub in .net and sending them to my android application (with notification hub).

At the moment, I receive the messages from the event hub using Event processor .

Now I want to forward them to my android application. What is the best way to complete this?

Answer 1

You're asking a very generic question, so I'm giving a very generic answer. If you'd like more information, please provide more details.

The general model would probably be something like this:

1. You need to 'register' every device that you would like to push to in the future.
2. Then somehow when the messages get into the event hub whoever sends them there needs to provide either an ID or a tag of the device(s) to send a push to.
3. When you know the ID/tag, send a push from your back-end .

I'd recommend linking your Event Hub with Notification Hubs via an Azure Function.

Step 1: Your Android device must register with the FCM to get a device token and then register the device with Notification Hubs. Since we are going to be dealing with Azure Functions, which is based on App Service, you can use App Service Push for this functionality - this will require a "HTTP POST" to the endpoint. See http://aka.ms/zumobook Chapter 5 for a Xamarin implementation of this.

Step 2: Create an Azure Function to link the event hub, do whatever processing you need and submit a push notification to the Notification Hub. See https://docs.microsoft.com/en-us/azure/azure-functions/ for the documentation source on this.
