一. 使用Docker安装rabbitmq

1.1 拉取有后台管理的镜像

docker pull rabbitmq:3.12.0-management

1.2 启动容器

docker run -d --hostname my-rabbit --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.12.0-management

1.3 访问http://localhost:15672/ 用户名密码都是guest

部署完成

二. golang使用rabbitmq示例代码

2.1 添加vhost

2.2 获取amqp库

go get -u github.com/streadway/amqp

2.3 consumer代码

package main

import (
	"fmt"
	"github.com/streadway/amqp"
)

func failOnError(err error, msg string) {
	if err != nil {
		fmt.Println("%s: %s", msg, err)
	}
}

// 只能在安装 rabbitmq 的服务器上操作
func main() {
	conn, err := amqp.Dial("amqp://guest:[email protected]/toutiao")
	failOnError(err, "Failed to connect to RabbitMQ")
	defer conn.Close()
	ch, err := conn.Channel()
	failOnError(err, "Failed to open a channel")
	defer ch.Close()
	q, err := ch.QueueDeclare(
		"toutiao.web.test", // 队列名字
		false,              // durable
		false,              // delete when unused
		false,              // exclusive
		false,              // no-wait
		nil,                // arguments
	)
	failOnError(err, "Failed to declare a queue")
	msgs, err := ch.Consume(
		q.Name,
		// queue
		"toutiao", // consumer
		true,      // auto-ack,true消费了就消失
		false,     // exclusive
		false,     // no-local
		false,     // no-wait
		nil,       // args
	)
	failOnError(err, "Failed to register a consumer")
	forever := make(chan bool)
	go func() {
		for d := range msgs {
			fmt.Println(fmt.Sprintf("返回的消息:%s", d.Body))
		}
	}()
	fmt.Println("[*] Waiting for messages. To exit press CTRL+C")
	<-forever
}

2.4 producer代码

package main

import (
	"github.com/streadway/amqp"
	"log"
)

func failOnError(err error, msg string) {
	if err != nil {
		log.Fatalf("%s: %s", msg, err)
	}
}

// 只能在安装 rabbitmq 的服务器上操作
func main() {
	conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/toutiao")
	failOnError(err, "Failed to connect to RabbitMQ")
	defer conn.Close()
	ch, err := conn.Channel()
	failOnError(err, "Failed to open a channel")
	defer ch.Close()
	q, err := ch.QueueDeclare(
		"toutiao.web.test", // name
		false,              // durable
		false,              // delete when unused
		false,              // exclusive
		false,              // no-wait
		nil,                // arguments
	)
	failOnError(err, "Failed to declare a queue")
	body := "Hello World!" //发送的消息
	err = ch.Publish(
		"",     // exchange
		q.Name, // routing key
		false,  // mandatory
		false,  // immediate
		amqp.Publishing{
			ContentType: "text/plain",
			Body:        []byte(body),
		})
	log.Printf(" [x] Sent %s", body)
	failOnError(err, "Failed to publish a message")
}
