一個服務端，一個客戶端，而且是阻塞方式，一次只能接受一個客戶端連接并通信噢。

客戶端發送‘bye', 結束與服務端的通信，如果發送’shutdown'，服務端將會關閉自己！

服務端代碼:

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
客戶端代碼:

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()
