python使用消息队列RabbitMq（入门）

windows平台开发和使用

安装

　　安装Erlang：https://pan.baidu.com/s/1QcZDaI205uaue7mMWh5cSA

　　安装RabbitMQ：https://pan.baidu.com/s/1r1TFv3m2SO8YmBenHMw62w

　　安装pika：pip install pika

配置

　　1、激活 RabbitMQ's Management Plugin：

"C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.5\sbin\rabbitmq-plugins.bat" enable rabbitmq_management

　　

　　

　　2、启动服务。请注意需要管理员身份才可以。

net stop RabbitMQ && net start RabbitMQ

　　

　　3、创建用户，密码，绑定角色

　　　　查看已有用户及用户的角色：

rabbitmqctl.bat list_users

　　

　　　　新增用户：

rabbitmqctl.bat add_user 用户名 密码

　　

　　　　设置管理员身份：

rabbitmqctl.bat set_user_tags user administrator

　　

　　　登录RabbitMQ，浏览器输入：

http://localhost:15672/

　　

　　设置账号

　　

可以看到

那让我们开始python编码吧

import pika
credentials = pika.PlainCredentials('admin','')
connection = pika.BlockingConnection(pika.ConnectionParameters(
    '127.0.0.1',5672,'/',credentials))
channel = connection.channel()

# 声明queue
channel.queue_declare(queue='balance')
data = 'Hello World,my name is hardy!'
# n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
channel.basic_publish(exchange='',
                      routing_key='balance',
                      body=data)
print(" [x] Sent '%s'"%data)
connection.close()

__author__ = 'Alex Li'
import pika

credentials = pika.PlainCredentials('admin','')
connection = pika.BlockingConnection(pika.ConnectionParameters(
    '127.0.0.1',5672,'/',credentials))
channel = connection.channel()

# You may ask why we declare the queue again ‒ we have already declared it in our previous code.
# We could avoid that if we were sure that the queue already exists. For example if send.py program
# was run before. But we're not yet sure which program to run first. In such cases it's a good
# practice to repeat declaring the queue in both programs.
channel.queue_declare(queue='balance')

def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)

channel.basic_consume(callback,
                      queue='balance',
                      no_ack=True)

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

注意：admin和123456是账号和密码。

至此，基本结束了，让我们进入进阶消息队列吧！
