基于udp协议实现QQ:可以并发一对多

##基于UDP协议实现QQ对话,可以实现一对多,服务端一个,客户端可以有多个
基本实现了对话功能,但是也是需要你来我往交互,一方不能连续发送两条数据

##服务端程序

import socketserver


class MyUdphandler(socketserver.BaseRequestHandler):
    def handle(self):
        data, sock = self.request
        print(data.decode('utf-8'))
        info = input('=====>>').strip()
        sock.sendto(info.encode('utf-8'), self.client_address)


if __name__ == '__main__':
    server = socketserver.ThreadingUDPServer(('127.0.0.1', 8081), MyUdphandler)
    server.serve_forever()


##客户端程序
from socket import *

client = socket(AF_INET, SOCK_DGRAM)

while True:
    # client.sendto(b'hello', ('127.0.0.1', 8081))
    info = input("=====>>>").strip()
    client.sendto(info.encode('utf-8'),('127.0.0.1',8081))

    data, server_addr = client.recvfrom(1024)
    print(data.decode('utf-8'))
