access List Connection pool:Redis-py uses connection pool to manage all connections to a Redis server, avoiding the overhead of each establishment and release of the connection. By default, each Redis instance maintains its own pool of connections. You can create a connection pool directly, and then as a parameter Redis, you can implement multiple Redis instances to share a single connection pool.

Server side:

Import Redisclass redishelper:    def __init__ (self):        self.__conn = Redis. Redis (host= ' 127.0.0.1 ')        self.chan_sub = ' fm87.7 '    def subscribe (self):        pub = Self.__conn.pubsub ()        Pub.subscribe (self.chan_sub)        pub.parse_response ()        return pubif __name__ = = ' __main__ ':    r = Redishelper ()    recv = R.subscribe ()            #订阅fm87.7 Channel while    True:                     #循环监听接收        print recv.parse_response ()     # Listen to the channel and receive messages from the client

Client side:

Import Redisclass redishelper:    def __init__ (self):        self.__conn = Redis. Redis (host= ' 127.0.0.1 ')        self.chan_pub = ' fm87.7 '    def Public (self,msg):   #发布内容到fm87. Channel 7        self.__ Conn.publish (Self.chan_pub, msg)        return trueif __name__ = = ' __main__ ':    t = redishelper ()    t.public (' Test ')        #test为发布的内容
