python网络编程

学习''Python核心编程第三版''2.1中的例子

服务端

__author__ = 'SkyQQ'

from socket import *
from time import ctime

HOST = ''
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)

tcpSerSock = socket(AF_INET, SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)

while True:
    print('Waiting for connection......')
    tcpCliSock, addr = tcpSerSock.accept()
    print('...connected from:', addr)

    while True:
        data = tcpCliSock.recv(BUFSIZ).decode()
        print('data =', data)
        if not data:
            break
        tcpCliSock.send(('[%s] %s' % (ctime(), data)).encode())

    tcpCliSock.close()
tcpSerSock.close()

客户端

__author__ = 'SkyQQ'

from socket import *

HOST = '127.0.0.1'  # or localhost
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)

tcpCliSock = socket(AF_INET, SOCK_STREAM)
tcpCliSock.connect(ADDR)

while True:
    data = input('> ')
    if not data:
        break
    tcpCliSock.send(data.encode())
    data = tcpCliSock.recv(BUFSIZ)
    if not data:
        break
    print(data.decode('utf-8'))

tcpCliSock.close()

期间还遇到了字符串转换的错误,上述代码是已经修改过的,解决过程离不开万能的百度

同时也给自己提个醒,永远不要忘记
