这篇文章主要介绍了Python网络编程之TCP与UDP协议套接字用法,结合实例形式较为详细的分析了Python网络编程中TCP与UDP协议客户端、服务器端相关实现及使用技巧,需要的朋友可以参考下

本文实例讲述了Python 网络编程之TCP与UDP协议套接字用法。分享给大家供大家参考，具体如下：

TCP协议

服务器端：

									#!/usr/bin/env python

									from socket import *

									from time import ctime

									HOST = ''

									PORT = 21567

									BUFSIZ = 1024

									ADDR = (HOST, PORT)

									tcpSerSock = socket(AF_INET, SOCK_STREAM) ##创建服务器TCP套接字

									tcpSerSock.bind(ADDR)

									tcpSerSock.listen(5)

									while True:

									  print 'waiting for connection...'

									  tcpCliSock, addr = tcpSerSock.accept() ##等待客户端连接

									  print '...connected from:', addr

									  while True:

									    data = tcpCliSock.recv(BUFSIZ) ##监听客户端是否发送消息

									    if not data:

									      break

									    tcpCliSock.send('[%s] %s' % (

									      ctime(), data))

									  tcpCliSock.close()

									tcpSerSock.close()

客户端：

									#!/usr/bin/env python

									from socket import *

									HOST = 'localhost'

									PORT = 21567

									BUFSIZ = 1024

									ADDR = (HOST, PORT)

									tcpCliSock = socket(AF_INET, SOCK_STREAM)  ##创建客户端TCP套接字

									tcpCliSock.connect(ADDR) ##连接服务器

									while True:

									  data = raw_input('> ')

									  if not data:

									    break

									  tcpCliSock.send(data)

									  data = tcpCliSock.recv(BUFSIZ) ##监听客户端发送消息

									  if not data:

									    break

									  print data

									tcpCliSock.close()

UDP协议

服务器端:

									#!/usr/bin/env python

									from socket import *

									from time import ctime

									HOST = ''

									PORT = 21567

									BUFSIZ = 1024

									ADDR = (HOST, PORT)

									udpSerSock = socket(AF_INET, SOCK_DGRAM)

									udpSerSock.bind(ADDR)

									while True:

									  print 'waiting for message...'

									  data, addr = udpSerSock.recvfrom(BUFSIZ)##监听并接受客户端发的消息

									  udpSerSock.sendto('[%s] %s' % (  ##给消息加上时间戳并返回给客户端

									    ctime(), data), addr)

									  print '...received from and returned to:', addr

									udpSerSock.close()

客户端：

									#!/usr/bin/env python

									from socket import *

									HOST = 'localhost'

									PORT = 21567

									BUFSIZ = 1024

									ADDR = (HOST, PORT)

									udpCliSock = socket(AF_INET, SOCK_DGRAM)

									while True:

									  data = raw_input('> ')

									  if not data:

									    break

									  udpCliSock.sendto(data, ADDR) ##给服务器发送数据

									  data, ADDR = udpCliSock.recvfrom(BUFSIZ) ##客户端接受带时间戳的数据

									  if not data:

									    break

									  print data

									udpCliSock.close()
