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.php.cn/zt/15841.html" 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)
    }
}
