服務器端：
#!/usr/bin/pythonimport sockethost='127.0.0.1'port=8123s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)s.bind((host,port))s.listen(2)try: while True: conn,add=s.accept while True: data2='' data1=conn.recv(3) if data1=='EOF': conn.send('hello clietn1') break if data1=='FOE': conn.send('hello client2') break data2+=data1 print data2except KeyboardInterrupt: print "you have CTRL+C,Now quit" s.close 註：服務器端一次只接收 3 個字節的數據，我讓讀取進入循環，然後不斷累加到 data2 中，當讀取到 EOF 時，退出打印 data2，當讀取 FOE 時，退出打印 data2，（EOF 和 FOE 是客戶端發送完數據時發送的結束符），當接收到 CTRLC+C 時，關閉 socket
