基於udp協議實現QQ:可以並發一對多

##基於UDP協議實現QQ對話,可以實現一對多,服務端一個,客戶端可以有多個
基本實現了對話功能,但是也是需要你來我往交互,一方不能連續發送兩條數據

##服務端程序

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()


##客戶端程序
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'))
