目标：
1.编写TCP服务端客户端，实现客户端发送数据，服务端接收打印
2.采用OOP方式编写TCP服务端客户端，实现客户端发送数据，服务端添加时间戳，返回给客户端
3.采用OOP方式编写UDP服务端客户端，实现客户端发送数据，服务端添加时间戳，返回给客户端。
1.编写TCP服务端客户端，实现客户端发送数据，服务端接收打印
服务端代码如下：
[root@localhost python]# cat tcpserver.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import sockethost = ''port = 8888addr = (host,port)s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)s.bind(addr)s.listen(1)while True: try: cli_sock, cli_addr = s.accept() except KeyboardInterrupt: break print "Client Connected From: ", cli_addr while True: cli_sock.send("I See You.\n") data = cli_sock.recv(1024) if not data.strip(): break print data cli_sock.close()s.close() 客户端代码如下：
[root@localhost python]# cat tcpclient.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import sockethost = ''port = 8888addr = (host, port)c = socket.socket(socket.AF_INET, socket.SOCK_STREAM)c.connect(addr)while True: print c.recv(1024), data = raw_input("> ") if not data.strip(): break c.send('%s\n' % data)c.close() •运行代码，测试效果
2.采用OOP方式编写TCP服务端客户端，实现客户端发送数据，服务端添加时间戳，返回给客户端
服务端代码如下：
[root@localhost python]# cat tcptimeserv.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import socketimport timeclass TcpTimeServ(object): def __init__(self, host, port): self.addr = (host, port) self.s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.s.bind(self.addr) self.s.listen(1) def handle_child(self, c_sock): while True: data = c_sock.recv(1024) if not data.strip(): break c_sock.send("[%s] %s\n" %(time.ctime(), data)) def mainloop(self): while True: try: cli_sock, cli_addr = self.s.accept() except KeyboardInterrupt: break print "Client Connected From: %s", cli_addr self.handle_child(cli_sock) cli_sock.close() self.s.close()if __name__ == "__main__": tcpserv = TcpTimeServ('0.0.0.0', 8888) tcpserv.mainloop() 客户端代码如下：
[root@localhost python]# cat tcptimecli.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import socketimport sysclass TcpTimeCli(object): def __init__(self, host, port): self.addr = (host, port) self.c = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.c.connect(self.addr) def mainloop(self): while True: data = raw_input("> ").strip() if not data: break self.c.send("%s" % data) print self.c.recv(1024) self.c.close()if __name__ == "__main__": host = sys.argv[1] port = int(sys.argv[2]) tcpcli = TcpTimeCli(host, port) tcpcli.mainloop() •运行代码，测试效果
3.采用OOP方式编写UDP服务端客户端，实现客户端发送数据，服务端添加时间戳，返回给客户端。
服务端代码如下：
[root@localhost python]# cat udpserver.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import socketimport timeclass UdpServ(object): def __init__(self, host, port): self.addr = (host, port) self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) self.s.bind(self.addr) def mainloop(self): while True: data, cli_addr = self.s.recvfrom(1024) data = data.strip() self.s.sendto('[%s] %s\n' %(time.ctime(), data), cli_addr) self.close()if __name__ == "__main__": host = '' port = 8888 udpserv = UdpServ(host, port) udpserv.mainloop() 客户端代码如下：
[root@localhost python]# cat udpclient.py
#!/usr/bin/env python# -*- coding: utf-8 -*-import socketimport sysclass UdpCli(object): def __init__(self, host, port): self.addr = (host, port) self.c = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) def mainloop(self): while True: data = raw_input("> ").strip() if not data: break self.c.sendto("%s\n" % data, self.addr) print self.c.recvfrom(1024)[0] self.c.close()if __name__ == "__main__": host = sys.argv[1] port = int(sys.argv[2]) udpcli = UdpCli(host, port) udpcli.mainloop() •运行代码，测试效果
