基于socketserver实现并发的socket套接字编程

并发：让服务端同时和多个客户端进行连接。使用socketserver的连接循环(并发),但是使用了自己的通信循环

服务端

import socketserver

print('start...')


class Myhandler(socketserver.BaseRequestHandler):
    # 通信循环
    def handle(self):
        while True:

            try:
                cmd = self.request.recv(1024)
                print('来自客户端数据：', cmd)

                self.request.send(cmd.upper())

            except ConnectionResetError:
                break


if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('127.0.0.1', 8000), Myhandler, bind_and_activate=True)
    server.serve_forever()

客户端1

from socket import *

client = socket(AF_INET, SOCK_STREAM)

client.connect(('127.0.0.1', 8000))

while True:

    client.send('cmd'.encode('utf8'))

    data = client.recv(1024)
    print(data.decode('gbk'))

客户端2

from socket import *

client = socket(AF_INET, SOCK_STREAM)

client.connect(('127.0.0.1', 8000))

while True:

    client.send('hello'.encode('utf8'))

    data = client.recv(1024)
    print('来自服务端的数据：',data.decode('gbk'))
