Python3中socket实现同步通信的实例讲解

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()
