Golang使用RabbitMQ消息中间件amqp协议

"github.com/streadway/amqp"

Publish发布

// amqp://:@:
var addr = "amqp://test:test123@127.0.0.1:5672" //test

func main() {

// 建立连接
conn, err := amqp.Dial(addr)
if nil != err {
logs.Error(err)
return
}

defer conn.Close()
// 申请通道
ch, err := conn.Channel()
if nil != err {
logs.Error(err)
return
}

defer ch.Close()
// 定义交换“direct”、“fanout”、“topic”和“headers”
err = ch.ExchangeDeclare("happy", amqp.ExchangeTopic, true, false, false, false, nil)
if nil != err {
logs.Error(err)
return
}

data = fmt.Sprintf("hello,world!!!")
//a.b.c.d.e 为发布key,以.分割；
err = ch.Publish("happy", "a.b.c.d.e", false, false,
amqp.Publishing{
ContentType: "text/plain",
Body: []byte(data),
DeliveryMode: amqp.Transient, // 1=non-persistent, 2=persistent
})
if nil != err {
logs.Error(err)
return
}

}

}

}

http管理端口是15672

注：队列应先注册一次，才能收到消息
