import socketserver

 ''' socketserver_server.py

    要使用socketserver实现服务器端代码编写需遵循的三步：

        .自己创建一个请求处理类，该类要继承BaseRequestHandler,且还要重写父类的handle()

        .实例化TCPServer(UDPServer),并传递server ip和上边创建的请求处理类给这个TCPServer(UDPServer)

        .调用实例的handle_request() or serve_forever()来分别处理一个请求或多个请求

 '''

 #请求处理类

 class Mysocket(socketserver.BaseRequestHandler):

     #重写父类的handle()

     def handle(self):

         while True:

             try:

                 self.data = self.request.recv().strip()

                 print(self.data.decode())

                 data = '收到消息'.encode()

                 self.request.send(data)

             except ConnectionResetError as e:

                 print('error occured：',e)

                 break

 if __name__ == '__main__':

     #指定服务器ip

     Host,Port = 'localhost',

     server = socketserver.TCPServer((Host,Port),Mysocket)

     server.serve_forever()

 import socket

 socketserver_client.py

 客户端和socket编程的客户端样，用到socket

 '''

 client = socket.socket()

 client.connect(('localhost',))

 while True:

     mes = input(">>:").strip()

     if len(mes) == :

         continue

     client.send(mes.encode())

     respose_data = client.recv()

     print(respose_data.decode())
