安装python pika库
pip install pika
编写发送消息client.py
1 # coding:utf8 2 3 import pika 4 5 connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost')) # 创建一个连接 6 channel = connection.channel() # 创建通道 7 channel.queue_declare(queue='hello') # 把消息队列的名字为hello 8 channel.basic_publish(exchange='', 9 routing_key='hello', 10 body='hello world!') # 设置routing_key(消息队列的名称)和body(发送的内容) 11 print(" [x] sent 'Hello World!'") 12 connection.close() # 关闭连接
编写监听消息队列server.py
1 # coding:utf8 2 3 import pika 4 5 connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost')) # 创建一个连接 6 channel = connection.channel() # 建立通道 7 channel.queue_declare(queue='hello') # 把消费者和queue绑定起来,生产者和queue的也是hello 8 9 10 def callback(ch, method, properties, body): # 回调函数get消息体 11 print(" [x] Received %r" % body) 12 13 14 channel.basic_consume(callback, 15 queue='hello', 16 no_ack=True) 17 18 print(' [*] Waiting for messages. To exit press CTRL+C') 19 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。
