問題描述

如何用加代碼可以使TCP客戶端的消息發送到TCP服務器上并print出來？

#!/usr/bin/env pythonfrom socket import *HOST=’’PORT=21567ADDR=(HOST,PORT)tcpSerSock=socket(AF_INET,SOCK_STREAM)tcpSerSock.bind(ADDR)tcpSerSock.listen(5)while True: print ’waiting for connection...’ tcpCliSock,addr=tcpSerSock.accept() print ’...connected from:’,addr while True: data=tcpCliSock.recv(1024) if not data:break tcpCliSock.send(data)tcpCliSock.close()tcpSerSock.close()#!/usr/bin/env pythonfrom socket import *HOST=’localhost’PORT=21567ADDR=(HOST,PORT)tcpCliSock=socket(AF_INET,SOCK_STREAM)tcpCliSock.connect(ADDR)while True: data=raw_input(’>’) if not data:break tcpCliSock.send(data) data=tcpCliSock.recv(1024) if not data:break print datatcpCliSock.close()

這是我的客戶端和服務器代碼，我不知道如何下手去改，現在就反饋主機序列號
