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()
