RabbitMQ消息队列跨语言demo（go和python）

前言

本文代码主要参考 RabbitMQ官方demo
RabbitMQ Tutorials

其中发送消息使用 python,接收消息使用go

基本条件：

类型	名称	内容
Operate System	Ubuntu	16.04
Message Queue	RabbitMQ	3.6.15
MQ Host	http address	192.168.105.132
MQ User	admin	123456

发送消息

使用 pyhon RabbitMQ库为pika
首先使用 python pip工具安装pika

pip intsall pika

显示已经安装软件

pip list

import pika 
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
channel.queue_declare(queue='hello')
channel.basic_publish(exchange='',
                      routing_key='hello',
                      body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()

接收消息

笔者go运行环境在window 系统中
使用go RabbitMQku 为 Go amqp client
运行go安装

go get github.com/streadway/amqp

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://admin:[email protected]: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(
        "hello", // name
        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
        "",     // consumer
        true,   // auto-ack
        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 {
            log.Printf("Received a message: %s", d.Body)
        }
    }()

    log.Printf(" [*] Waiting for messages. To exit press CTRL+C")
    <-forever
}
