基于python3的socket聊天编程

阶段一：最简易的聊天系统

缺点：程序不够完善，只能一来一回，且没人每次只能说一句话

server端：

import socket

HostPort = ('127.0.0.1',9999)

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.bind(HostPort)

s.listen(1)

conn,addr = s.accept()

while 1:

data = conn.recv(1024).decode()

print (data)

user_input = input('>>>')

conn.send(user_input.encode('utf8'))

s.close()

client端：

import socket

hostport = ('127.0.0.1',9999)

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.connect(hostport)

while 1:

user_input = input('>>> ').strip()

s.send(user_input.encode('utf-8'))

if len(user_input) == 0:

continue

if user_input == 'quit':
