使用golang调用RocketMQ SDK

本文档介绍使用go语言调用火山引擎RocketMQ SDK。

• 预计部署时间：30分钟
• 级别：初级
• 相关产品：中间件-RocketMQ
• 受众： 通用

第一步、创建RocketMQ实例

在控制台创建RocketMQ实例，并配置Topic、Group、以及秘钥，详见RocketMQ创建文档

第二步 、配置golang代码

// Package main implements a producer with user custom interceptor.
package main

import (
	"context"
	"fmt"
	"os"

	"github.com/apache/rocketmq-client-go/v2"
	"github.com/apache/rocketmq-client-go/v2/primitive"
	"github.com/apache/rocketmq-client-go/v2/producer"
)

func main() {
	p, err := rocketmq.NewProducer(
		producer.WithNsResolver(primitive.NewPassthroughResolver([]string{"Your TCP intranet access point"})),//此处填写控制台RocketMQ实例概览中的TCP内网接入点，目前不支持公网接入，示例http://MQ_INST_50392uo8m9em_xxxxx.rocketmq.ivolces.com:9876
		producer.WithRetry(2),
		producer.WithCredentials(primitive.Credentials{
			AccessKey: "your AccessKey",
			SecretKey: "your SecretKey",
		}),
	)

	if err != nil {
		fmt.Println("init producer error: " + err.Error())
		os.Exit(0)
	}

	err = p.Start()
	if err != nil {
		fmt.Printf("start producer error: %s", err.Error())
		os.Exit(1)
	}
	for i := 0; i < 100000; i++ {MQ_INST_50392uo8m9em_8f96x
		res, err := p.SendSync(context.Background(), primitive.NewMessage("your topic", //示例：MQ_INST_50392uo8m9em_xxxxx%test test为创建的topic名称 MQ_INST_50392uo8m9em_xxxxx为实例ID
			[]byte("Hello RocketMQ Go Client!")))

		if err != nil {
			fmt.Printf("send message error: %s\n", err)
		} else {
			fmt.Printf("send message success: result=%s\n", res.String())
		}
	}
	err = p.Shutdown()
	if err != nil {
		fmt.Printf("shutdown producer error: %s", err.Error())
	}
}

第三步、交叉编译代码并上传到ECS实例进行测试

linux

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build main.go

Windows

CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build main.go

Mac

CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build main.go

上传完成后，执行代码，显示结果如下。

send message success: result=SendResult [sendStatus=0, msgIds=C0A8005815C900000000226ee5480532, offsetMsgId=AC1C3961000078BF000000000029EE54, queueOffset=1268, messageQueue=MessageQueue [topic=MQ_INST_50392uo8m9em_8f96x%test, brokerName=brk-2c6afc0c-21e683427f49-223046fbe3aa, queueId=2]]
