服務器端：
#!/usr/bin/pythonimport sockethost=''127.0.0.1''port=8123s=socket.socket(socket.af_,socket.sock_stream)s.bind((host,port))s.listen(2)try: while true: conn,add=s.ept 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 </pre>
注：服務器端一次隻接收 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
