本文介绍了如何使用pika库在Python中与RabbitMQ进行消息通信，包括发送和接收消息的示例代码。

RabbitMQ做外AMQP的实现，现在在很多企业中作为消息中心在运用。

RabbitMQ在Python中，采用pika工具进行操作。在之前的版本里，也有采用py-amqplib工具，但后面几乎不再采用。

以下是笔者的一两个小实验。

getMessage.py

#!/usr/bin/env python
import pika
import random

credentials = pika.PlainCredentials('crawler', 'Abc12345')

parameters = pika.ConnectionParameters('192.168.161.110',5672,'crawler',credentials) 
connection = pika.BlockingConnection(parameters)
channel = connection.channel()

print ' [*] Waiting for messages. To exit press CTRL+C'    
        
def callback(ch, method, properties, body):    
    print " [x] Received %r" % (body,)    
        
channel.basic_consume(callback,queue='taobao.policy',no_ack=True)    
        
channel.start_consuming()

sendMessage.py

#!/usr/bin/env python
import pika
import random

credentials = pika.PlainCredentials('crawler', 'Abc12345')

parameters = pika.ConnectionParameters('192.168.161.110',5672,'crawler',credentials) 
connection = pika.BlockingConnection(parameters)
channel = connection.channel()

print ' [*] Waiting for messages. To exit press CTRL+C'    
        
def callback(ch, method, properties, body):    
    print " [x] Received %r" % (body,)    
        
channel.basic_consume(callback,queue='taobao.policy',no_ack=True)    
        
channel.start_consuming()
