基于UDP协议简单聊天

server端

import socket

sk = socket.socket(type=socket.SOCK_DGRAM)
sk.bind(('127.0.0.1',8080))
while True:
    msg,addr = sk.recvfrom(1024)
    print(msg.decode('utf-8'))
    info = input('>>>')
    info = ('\033[0;32;40m来自server端的消息：%s\033[0m'%info).encode('utf-8')
    sk.sendto(info,addr)

sk.close()

client端

import socket
ip_port = ('127.0.0.1',8080)
sk = socket.socket(type=socket.SOCK_DGRAM)
while True:
    info = input('>>>')
    if info == 'bye':
        sk.sendto(b'bye',ip_port)
        break

    info = ('\033[34m来自tiger的消息：%s\033[0m'%info).encode('utf-8')
    sk.sendto(info,ip_port)
    msg,addr = sk.recvfrom(1024)
    print(msg.decode('utf-8'))

sk.close()
