1.准备工作
启动rabbitmq_server，在浏览器上打开rabbitMQ的管理器
2.发送端程序
开始如果导入
"github.com/streadway/amqp" 出现错误，则先在goLand下面的终端，运行go get "github.com/streadway/amqp"
package main
import (
"log"
"github.com/streadway/amqp"
"strconv"
)
func failOnError(err error, msg string) {
if err != nil {
log.Fatalf("%s: %s", msg, err)
}
}
func main() {
conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/") // 建立连接
failOnError(err, "Failed to connect to RabbitMQ")
defer conn.Close()
ch, err := conn.Channel() // 创建channel
failOnError(err, "Failed to open a channel")
defer ch.Close()
/*
Delivery Exchange Key Queue
-----------------------------------------------
key: alerts -> "" -> alerts -> alerts
*/
q, err := ch.QueueDeclare( // 创建消息队列，queue，并分配默认binding，empty exchange
"hello", // name 消息队列的名字
false, // durable // 队列持久化
false, // delete when unused
false, // exclusive
false, // no-wait
nil, // arguments
)
failOnError(err, "Failed to declare a queue")
for i:=0; i<100; i++ {
body := "hello" + strconv.Itoa(i)
err = ch.Publish( // 发布消息，第一个参数表示路由名称（exchange），""则表示使用默认消息路由
"", // exchange
q.Name, // routing key "hello"
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")
}3.接受端程序
package main
import (
"log"
"github.com/streadway/amqp"
)
func failOnError(err error, msg string) {
if err != nil {
log.Fatalf("%s: %s", msg, err)
}
}
func main() {
conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/")
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( // 消息队列
"hello", // name
false, // durable 队列持久化
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
"", // consumer
true, // auto-ack 自动ACK
false, // exclusive
false, // no-local
false, // no-wait
nil, // args
)
failOnError(err, "Failed to register a consumer")
forever := make(chan bool) // 创建bool型的channel
go func() {
for d := range msgs {
log.Printf("Received a message: %s", d.Body)
}
}()
log.Printf(" [*] Waiting for messages. To exit press CTRL+C")
<-forever // 从forever信道中取数据，必须要有数据流进来才可以，不然main在此阻塞
}4.运行程序
启动一个发送程序，启动两个接受程序
发送方：
| 接受方1 | 接受方2 |
