Python--TCP时间服务器

实现一个时间服务器，客户端连接上服务端后，客户端发送的消息会加上时间戳后返回。

服务端

#coding:utf-8 from socket import * from time import ctime HOST = '' PORT = 21567 BUFSIZE = 1024 ADDR = (HOST,PORT) tcp_ser_socket = socket(AF_INET,SOCK_STREAM) tcp_ser_socket.bind(ADDR) tcp_ser_socket.listen(5) while True: print 'waiting for connection..' tcp_client_socket , addr = tcp_ser_socket.accept() print '...connected from:',addr while True: data = tcp_client_socket.recv(BUFSIZE) if not data: break tcp_client_socket.send('[%s] %s' % (ctime(),data)) tcp_client_socket.close() # 这句其实没用，实际中可以添加守护进程， # 上面的while循环通过判断守护进程是否存在来决定是否要退出 tcp_ser_socket.close()

客户端

from socket import * HOST = '192.168.233.130' PORT = 21567 BUFSIZE = 1024 ADDR = (HOST,PORT) tcp_client_socket = socket(AF_INET,SOCK_STREAM) tcp_client_socket.connect(ADDR) while True: data = raw_input('> ') if not data: break tcp_client_socket.send(data) data = tcp_client_socket.recv(BUFSIZE) if not data: break print data tcp_client_socket.close()

运行服务端程序： root@ubuntu:/home/fl# python tcp_server.py waiting for connection..

运行客户端程序： D:>C:\Python27\python client.py > nihao [Mon Aug 7 07:54:29 2017] nihao > hello [Mon Aug 7 07:54:39 2017] hello
