socketserver

创建socketserver三步：

1、你必须自己创建一个请求处理类，并且这个类要继承BaseRequestHandler，并且还要重写父类里的handle()，server端和client所有的交互都在handle()里面完成；
2、你必须实例化TCPServer，并且传递Server IP 和你上面创建的请求处理类给这个TCPserver；
3、server.serve_forever()    # 处理多个请求，永远执行

代码饭粒：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# Date: 2017/11/29
# server

import socketserver
class FoneSocketServer(socketserver.BaseRequestHandler):
    def handle(self):
        try:
            while True:
                self.data = self.request.recv(1024).strip()
                print("%s send: " % self.client_address[0])
                print(self.data.decode())
                self.request.send(self.data.upper())
        except ConnectionResetError as e:
            print("Error: ",e)

HOST, PORT = 'localhost', 9999
server = socketserver.ThreadingTCPServer((HOST,PORT),FoneSocketServer)
server.serve_forever()

 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# client

import socket
client = socket.socket()
client.connect(('localhost',9999))
while True:
    msg = input("Please input message:")
    if len(msg) == 0:continue
    client.send(msg.encode('utf-8'))
    data = client.recv(1024)
    if not data:
        print('Server has lost...')
        break
    print('recv:',data.decode())
client.close()
