Python-Redis的发布与订阅

封装的redis_config

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

import redis

class RedisConfig:

    def __init__(self):
        self.__conn = redis.Redis(host='192.168.220.144')
        self.chan_sub = 'redis_queue'
        self.chan_pub = 'redis_queue'
        # 一个给发布端，一个给订阅端

    def public(self, msg):  # 发布端
        self.__conn.publish(self.chan_pub, msg)  # 发送消息
        return True

    def subscribe(self):  # 订阅端
        pub = self.__conn.pubsub()  # 打开接收
        pub.subscribe(self.chan_sub)  # 选择要监听的queue
        pub.parse_response()  # 准备接收
        return pub

Redis发布端

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

from redis_config import RedisConfig

obj = RedisConfig()
obj.public('hello world!')

Redis订阅端

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

from redis_config import RedisConfig

obj = RedisConfig()
redis_sub = obj.subscribe()

while True:
    msg = redis_sub.parse_response()
    print(msg)

运行结果

也可以直接通过redis发布消息
