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 ctimeHOST = ''
PORT = 21567
BUFSIZE = 1024
ADDR = (HOST, PORT)tcpSerSock = socket(AF_INET, SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
quit = False
shutdown = Falsewhile 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:breakss = '[%s] %s' %(ctime(), data)tcpCliSock.send(ss.encode('utf8'))print(ss)if data == 'bye':quit = Truebreakelif data == 'shutdown':shutdown = Truebreakprint('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:continueprint('input data: [%s]' %data)tcpCliSock.send(data.encode('utf8'))rdata = tcpCliSock.recv(BUFSIZE)if not rdata:breakprint(rdata.decode('utf8'))if data == 'bye' or data == 'shutdown':breaktcpCliSock.close()
