这篇文章主要介绍了Python3 socket同步通信功能,结合简单实例形式分析了Python socket同步通信客户端与服务器端实现技巧,需要的朋友可以参考下

本文实例讲述了Python3 socket同步通信。分享给大家供大家参考，具体如下：

本文比较简单，适合入门用，作个笔记，方便日后抄写

一个服务端，一个客户端，而且是阻塞方式，一次只能接受一个客户端连接并通信噢。

客户端发送‘bye', 结束与服务端的通信，如果发送'shutdown'，服务端将会关闭自己！

服务端代码:

									from socket import *

									from time import ctime

									HOST = ''

									PORT = 21567

									BUFSIZE = 1024

									ADDR = (HOST, PORT)

									tcpSerSock = socket(AF_INET, SOCK_STREAM)

									tcpSerSock.bind(ADDR)

									tcpSerSock.listen(5)

									quit = False

									shutdown = False

									while True:

									  print('waiting for connection...')

									  tcpCliSock, addr = tcpSerSock.accept()

									  print('...connected from: ', addr)

									  while True:

									    data = tcpCliSock.recv(BUFSIZE)

									    data = data.decode('utf8')

									    if not data:

									      break

									    ss = '[%s] %s' %(ctime(), data)

									    tcpCliSock.send(ss.encode('utf8'))

									    print(ss)

									    if data == 'bye':

									      quit = True

									      break

									    elif data == 'shutdown':

									      shutdown = True

									      break

									  print('Bye-bye: [%s: %d]' %(addr[0], addr[1]))

									  tcpCliSock.close()

									  if shutdown:

									    break

									tcpSerSock.close()

									print('Server has been

客户端代码:

									from socket import *

									HOST = 'localhost'

									PORT = 21567

									BUFSIZE = 1024

									ADDR = (HOST, PORT)

									tcpCliSock = socket(AF_INET, SOCK_STREAM)

									tcpCliSock.connect(ADDR)

									while True:

									  data = input('>')

									  if not data:

									    continue

									  print('input data: [%s]' %data)

									  tcpCliSock.send(data.encode('utf8'))

									  rdata = tcpCliSock.recv(BUFSIZE)

									  if not rdata:

									    break

									  print(rdata.decode('utf8'))

									  if data == 'bye' or data == 'shutdown':

									    break

									tcpCliSock.close()
