服务端代码

#引入socketserver模块

import socketserver

#定义处理类必须继承BaseRequestHandler类

class my_server(socketserver.BaseRequestHandler):

    def handle(self):

        #获取连接

        print(self.request) #conn

        #获取地址

        print(self.client_address)#addr

        while True:

            try:

               # 收消息

                data=self.request.recv(1024)

               #可能会出现不断的收

                if  not data:break

                #self.request:连接信息 self.client_address：链接地址

                print("a client is connented", self.request, ":", self.client_address)

                print("收到客户端消息是：",data.decode("utf-8"))

                #发消息

                self.request.sendall(data)

            except Exception as e:

                print(e)

                break

if __name__=='__main__':

    print("This server is started")

    #多线程

    s=socketserver.ThreadingTCPServer(('127.0.0.1',8080)  ,my_server)

    #永远服务

    s.serve_forever()

客户端代码

from socket import *

ip_port=("127.0.0.1",8080)

buffer_size=1024

#客户端

tcp_client=socket(AF_INET,SOCK_STREAM)

#连接服务端

tcp_client.connect(ip_port)

while True:

    msg=input("===>:")

    tcp_client.send(msg.encode("utf- 8"))

    data=tcp_client.recv(buffer_size)

    print("收到的服务端消息为：",data.decode("utf-8"))

tcp_client.close
