二：

任务分发 &消息持久化

 

启用多个接收端的时候如果某一个receive 关闭要保证消息有反馈是否收到

 

send端

#-*- coding: UTF-8 -*-
import pika
cred = pika.PlainCredentials(‘zxl‘,‘pwd‘) #账号密码
params = pika.ConnectionParameters(host=‘192.168.110.233‘,port=5672,credentials=cred) #条件设置
connection = pika.BlockingConnection(params) #给定条件
channel = connection.channel()
channel.queue_declare(queue=‘t_list‘,durable=True) #创建一个t_list 队列
for i in range(0,100):
    content = ‘ ni hao is hello‘+str(i)
    channel.basic_publish(exchange=‘‘,
                          routing_key=‘t_list‘,
                          body=content,
                          properties=pika.BasicProperties(delivery_mode=2) #确保消息持久
                          )
print(‘send hello‘)
print(channel)
connection.close()

receive 端

#-*- coding: UTF-8 -*-
import pika
import time
cred = pika.PlainCredentials(‘zxl‘,‘pwd‘) #账号密码
params = pika.ConnectionParameters(host=‘192.168.110.233‘,port=5672,credentials=cred) #条件设置
connection = pika.BlockingConnection(params) #给定条件
channel = connection.channel()
channel.queue_declare(queue=‘t_list‘,durable=True)

def callback(ch,method,properties,body):
   print " [x] Received %r" % (body,)
   time.sleep(2)
   ch.basic_ack(delivery_tag = method.delivery_tag)

channel.basic_consume(callback,queue = ‘t_list‘,no_ack = False) #no_ack 自动应答改为False
print("starting")
channel.start_consuming()
