用 udp 实现简单版本的qq

服务端

import socket


server = socket.socket(type=socket.SOCK_DGRAM)
server.bind((‘127.0.0.1‘,8080))

while True:
    data, addr = server.recvfrom(1024)
    print(data.decode(‘utf-8‘))
    msg = input(‘>>>:‘)
    server.sendto(msg.encode(‘utf-8‘),addr)

客户端

import socket


client = socket.socket(type=socket.SOCK_DGRAM)
server_address = (‘127.0.0.1‘,8080)

while True:
    msg = input(‘>>>:‘)
    msg = ‘来自客户端1的消息:%s‘%msg
    client.sendto(msg.encode(‘utf-8‘),server_address)
    data, server_addr = client.recvfrom(1024)
    print(data.decode(‘utf-8‘))
