socketserver模块 ( 基于 udp 协议 )

服务端：

import socketserver
class MyUDPhandler(socketserver.BaseRequestHandler):
    def handle(self):
        date,sock = self.request
        sock.sendto(date.upper(),self.client_address)

if __name__ == '__male__':
    server = socketserver.ThreadingUDPServer(('127.0.0.1',8081),MyUDPhandler)
    server.serve_forever()

客户端：

from socket import *
client = socket(AF_INET,SOCK_DGRAM)
while True:
    client.sendto(b'wxx',('127.0.0.1',8081))
    date,server_addr = client.recvfrom(1024)
    print(date)
