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：
立即学习“go语言免费学习笔记（深入）”；
- 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：
go get -u <a style='color:#f60; text-decoration:underline;' href="https://www.codesou.cn/" target="_blank">git</a>hub.com/Azure/azure-sdk-for-go/servicebus
创建 Service Bus 客户端：
import (
"context"
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
}
接收消息：
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
}
实战案例：
以下是使用此库在 Golang 框架中使用 Azure Service Bus 消息队列的一个实战案例：
package main
import (
"context"
"fmt"
"log"
"time"
"github.com/Azure/azure-sdk-for-go/servicebus/messaging"
)
func main() {
connectionString := "YOUR_CONNECTION_STRING"
queueName := "YOUR_QUEUE_NAME"
client, err := createClient(connectionString)
if err != nil {
log.Fatalf("error creating client: %v", err)
}
defer client.Close(context.Background())
sender, err := createQueueSender(client, queueName)
if err != nil {
log.Fatalf("error creating sender: %v", err)
}
defer sender.Close(context.Background())
for i := 0; i < 10; i++ {
msg := fmt.Sprintf("Message #%d", i)
if err := sendMessage(sender, msg); err != nil {
log.Fatalf("error sending message: %v", err)
}
fmt.Println("Message sent:", msg)
time.Sleep(1 * time.Second)
}
receiver, err := createQueueReceiver(client, queueName)
if err != nil {
log.Fatalf("error creating receiver: %v", err)
}
defer receiver.Close(context.Background())
for {
msg, err := receiveMessage(receiver)
if err != nil {
log.Fatalf("error receiving message: %v", err)
}
fmt.Println("Message received:", msg)
}
}
