1、Service.py

2、Client.py

# encoding=utf-8# 载入模块from socket import *  import json, time, threadingimport structfrom urllib import unquote"""1、客服端与服务端建立连接2、把客户端的链接存入redis中3、客户端与客户端通过对方链接进行通信4、实现对话优化"""class Client():    def __init__(self):        self.sock = socket(AF_INET, SOCK_STREAM)            self.sock.connect(('localhost', 11011))          self.sock.send(b'B')#发送一个1                print(self.sock.recv(1024).decode())        print u"\n已建立连接..."        self.sock.close()        if __name__ == '__main__':        c = Client()

3、Redis.py

操作Redis的一些方法

# encoding=utf-8# 载入模块import redis# 链接redis数据库r = redis.Redis(host='localhost', port=6379, db=0)# 往redis中写数据r.set('hello','world')print(r.get('hello'))r.set('Key', 'value')# 查看对应的值print 'Key', r.get('Key')r['diaosi'] = 'yy'r.set('xueba', 'xuexi')r['xuezha'] = 'wan'print (r.get('xuezha'))# 查看数据库中有多少个key，多少条数据print r.dbsize()# 将数据保存到硬盘中（保存时阻塞）r.save()# 查看键值是否存在print "是否存在结果为:",r.exists("doubi")# 列出所有键值print "列出所有键值",r.keys()# 删除键值对应的数据print r.delete('diaosi')print r.delete('xuezha')# 删除当前数据库所有数据r.flushdb()
