安装python pika库

pip install pika

编写发送消息client.py

 # coding:utf8

 import pika

 connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))  # 创建一个连接
 channel = connection.channel()  # 创建通道
 channel.queue_declare(queue='hello')  # 把消息队列的名字为hello
 channel.basic_publish(exchange='',
                       routing_key='hello',
                       body='hello world!')  # 设置routing_key(消息队列的名称)和body(发送的内容)
 print(" [x] sent 'Hello World!'")
 connection.close()  # 关闭连接

编写监听消息队列server.py

 # coding:utf8

 import pika

 connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))  # 创建一个连接
 channel = connection.channel()  # 建立通道
 channel.queue_declare(queue='hello')  # 把消费者和queue绑定起来,生产者和queue的也是hello

 def callback(ch, method, properties, body):  # 回调函数get消息体
     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()  # 创建死循环，监听消息队列，可使用CTRL+C结束监听

执行server.py可以监听消息队列，执行client.py启动客户端向消息队列发送消息。
