Python3-RabbitMQ 3.7.2学习——Hello World（二）

RabbitMQ环境搭建好了，接下来就是学习编程的入门级hello world.

在运行程序前，要先确保开启RabbitMQ服务

而后安装pika，命令：pip install pika

1.建立一个python工程，我建立的名为RabitMQ_Demo

2,建立一个send.py

#!/usr/bin/env python3.5.2
# -*- coding: utf-8 -*-

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
        host='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()

3,建立一个receive.py

#!/usr/bin/env python3.5.2
# -*- coding: utf-8 -*-

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
        host='localhost'))
channel = connection.channel()


channel.queue_declare(queue='hello')

def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)

channel.basic_consume(callback,
                      queue='hello',
                      no_ack=True)

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

4.运行。

　　（1），先运行receive.py

           

　　(2)，而后运行send.py

          

          

就此，helloworld就完了，接下来，就去网站上去找教程，加深学习。
