1.docke 中安装 rabbitmq
docker pull rabbitmq
2.运行 rabbitmq
docker run -d --name rabbitmq -p 5671:5671 -p 5672:5672 -p 4369:4369 -p 25672:25672 -p 15671:15671 -p 15672:15672 rabbitmq:latest
3.下载 rabbitmq golang 客户端
go get github.com/streadway/amqp
4.send.go
1 package main
2
3 import (
4 "log"
5
6 "github.com/streadway/amqp"
7 )
8
9 func failOnError(err error, msg string) {
10 if err != nil {
11 log.Fatalf("%s: %s", msg, err)
12 }
13 }
14
15 // 只能在安装 rabbitmq 的服务器上操作
16 func main() {
17 conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/")
18 failOnError(err, "Failed to connect to RabbitMQ")
19 defer conn.Close()
20
21 ch, err := conn.Channel()
22 failOnError(err, "Failed to open a channel")
23 defer ch.Close()
24
25 q, err := ch.QueueDeclare(
26 "hello", // name
27 false, // durable
28 false, // delete when unused
29 false, // exclusive
30 false, // no-wait
31 nil, // arguments
32 )
33 failOnError(err, "Failed to declare a queue")
34
35 body := "Hello World!"
36 err = ch.Publish(
37 "", // exchange
38 q.Name, // routing key
39 false, // mandatory
40 false, // immediate
41 amqp.Publishing{
42 ContentType: "text/plain",
43 Body: []byte(body),
44 })
45 log.Printf(" [x] Sent %s", body)
46 failOnError(err, "Failed to publish a message")
47 }
5.recv.go
1 package main
2
3 import (
4 "log"
5
6 "github.com/streadway/amqp"
7 )
8
9 func failOnError(err error, msg string) {
10 if err != nil {
11 log.Fatalf("%s: %s", msg, err)
12 }
13 }
14
15 // 只能在安装 rabbitmq 的服务器上操作
16 func main() {
17 conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/")
18 failOnError(err, "Failed to connect to RabbitMQ")
19 defer conn.Close()
20
21 ch, err := conn.Channel()
22 failOnError(err, "Failed to open a channel")
23 defer ch.Close()
24
25 q, err := ch.QueueDeclare(
26 "hello", // name
27 false, // durable
28 false, // delete when unused
29 false, // exclusive
30 false, // no-wait
31 nil, // arguments
32 )
33 failOnError(err, "Failed to declare a queue")
34
35 msgs, err := ch.Consume(
36 q.Name, // queue
37 "", // consumer
38 true, // auto-ack
39 false, // exclusive
40 false, // no-local
41 false, // no-wait
42 nil, // args
43 )
44 failOnError(err, "Failed to register a consumer")
45
46 forever := make(chan bool)
47
48 go func() {
49 for d := range msgs {
50 log.Printf("Received a message: %s", d.Body)
51 }
52 }()
53
54 log.Printf(" [*] Waiting for messages. To exit press CTRL+C")
55 <-forever
56 }
6.分别在在两个窗口执行
go run ./send.go
2018/08/22 15:48:13 [x] Sent Hello World!
go run ./recv.go
2018/08/22 15:48:16 [*] Waiting for messages. To exit press CTRL+C
2018/08/22 15:48:16 Received a message: Hello World!
