How do I keep my consumer listening the messages on Azure Sevice Bus using Azure sdk for Golang v0.3.1?

I've been using the module azure-sdk-for-go/sdk/messaging/azservicebus v0.3.1 to connect my consumer with Azure Service Bus but the code implemented only receive a fixed number of message and then stop the application and I'would like to keep the consumer listening the queue. Follow my code:

	client, err := azservicebus.NewClientFromConnectionString("Connection String", nil)
    
    if err != nil {
		log.Fatalf("Failed to create Service Bus Client: %s", err.Error())
	}

    receiver, err := client.NewReceiverForQueue("queue", nil)

    if err != nil {
		log.Fatalf("Failed to create Consumer: %s", err.Error())
	}

    messages, err := receiver.ReceiveMessages(context.TODO(), 10, nil)

    if err != nil {
		log.Fatalf("Failed to receive Messages: %s", err.Error())
	}

    for _, message := range messages {

		body, err := message.Body()

		if err != nil {
			log.Fatalf("Failed to parse message body: %s", err.Error())
		}

		fmt.Println("Message --->", string(body))

		err = receiver.CompleteMessage(context.TODO(), message)

        if err != nil {
			log.Fatalf("Failed to complete message: %s", err.Error())
		}

		fmt.Printf("Received and completed message\n")

	}

You have 99% of the code - as you noted ReceiveMessages only returns the amount you requested.

So you just want to wrap your logic in a loop so you can run it continually:

for {
	messages, err := receiver.ReceiveMessages(context.TODO(), 10, nil)
	if err != nil {
		log.Fatalf("Failed to receive Messages: %s", err.Error())
	}

	for _, message := range messages {
		body, err := message.Body()

		if err != nil {
			log.Fatalf("Failed to parse message body: %s", err.Error())
		}

		fmt.Println("Message --->", string(body))

		err = receiver.CompleteMessage(context.TODO(), message)

		if err != nil {
			log.Fatalf("Failed to complete message: %s", err.Error())
		}
	}
}

BTW, 0.3.2 was just released and it contains some fixes that you'll be interested in as they do affect ReceiveMessages.
