Python通过RabbitMQ服务器实现交换机功能的实例教程

sudo apt-get install rabbitmq-server

sudo pip install pika

#!/usr/bin/env python
#coding=utf8
import pika
 
connection = pika.BlockingConnection(pika.ConnectionParameters(
        'localhost'))
channel = connection.channel()
 
#定义交换机
channel.exchange_declare(exchange='messages', type='fanout')
 
#随机生成队列，并绑定到交换机上
result = channel.queue_declare(exclusive=True)
queue_name = result.method.queue
channel.queue_bind(exchange='messages', queue=queue_name)
 
def callback(ch, method, properties, body):
  print " [x] Received %r" % (body,)
 
channel.basic_consume(callback, queue=queue_name, no_ack=True)
 
print ' [*] Waiting for messages. To exit press CTRL+C'
channel.start_consuming()

#!/usr/bin/env python
#coding=utf8
import pika
 
connection = pika.BlockingConnection(pika.ConnectionParameters(
        'localhost'))
channel = connection.channel()
 
#定义交换机
channel.exchange_declare(exchange='messages', type='fanout')
 
#将消息发送到交换机
channel.basic_publish(exchange='messages', routing_key='', body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()
