在 golang 框架中集成 azure service bus 消息队列步骤如下：安装 microsoft 的 golang service bus 库。创建 service bus 客户端。创建队列发送器。发送消息。创建队列接收器。接收消息。
如何在 Golang 框架中使用 Azure Service Bus 消息队列
Azure Service Bus 是一种完全托管的消息代理服务，可简化应用程序之间的可靠通信。本教程将指导你如何使用 Golang 库，在 Golang 框架中集成 Azure Service Bus 消息队列。
先决条件：
安装并配置 Golang 1.16 或更高版本 已有 Azure 帐户和 Azure Service Bus 命名空间安装库：
使用以下命令安装 Microsoft 提供的 Golang Service Bus 库：

import (

servicebus "github.com/Azure/azure-sdk-for-go/servicebus/messaging"
)
func createClient(connectionString string) (servicebus.Client, error) {
client, err := servicebus.NewClientFromConnectionString(connectionString)
if err != nil {
return nil, err
}
return client, nil
}
创建队列发送器：

func createQueueSender(client servicebus.Client, queueName string) (servicebus.Sender, error) {
sender, err := client.NewSender(servicebus.QueueName(queueName))
if err != nil {
return nil, err
}
return sender, nil
}
发送消息：

func sendMessage(sender servicebus.Sender, msg string) error {
message := servicebus.NewMessage([]byte(msg))
if err := sender.Send(context.Background(), message); err != nil {
return err
}
return nil
}
创建队列接收器：

func createQueueReceiver(client servicebus.Client, queueName string) (servicebus.Receiver, error) {
receiver, err := client.NewReceiver(servicebus.QueueName(queueName))
if err != nil {
return nil, err
}
return receiver, nil
}

func receiveMessage(receiver servicebus.Receiver) (string, error) {
ctx := context.Background()
msg, err := receiver.Receive(ctx)
if err != nil {
return "", err
}
defer msg.Complete(ctx)
body, err := msg.GetBody()
if err != nil {
return "", err
}
return string(body), nil
}
