Question:
You've been tasked with developing a system to handle real-time reactions to blog posts on a website. The system needs to notify all registered users whenever a new blog post is published. What Azure services would you recommend to set up the Azure function? Fill in the triggers and bindings in the following code:
[FunctionName("NotifyUsers")]
public static async void Run(
/* Triggers and Bindings here */
ILogger log)
{
// Process the incoming event
// Prepare the notification based on the blog post data
// Use HttpClient to send the notification to all registered users
}
Answer:
For real-time notifications, you could use an Event Grid trigger. When a new blog post is published, it can trigger an event which in turn triggers the Azure function. The function could then use an output binding to a Service Bus topic to notify all registered users.
[FunctionName("NotifyUsers")]
public static async void Run(
[EventGridTrigger]
EventGridEvent eventGridEvent,
ILogger log)
{
// Process the incoming event
// Prepare the notification based on the blog post data
// Use HttpClient to send the notification to all registered users
}
