预期目标：

（1）服务器地址、端口号通过终端传入

（2）服务器需要完成请求监听、接收数据、发送数据、断开连接

（3）客户端需要完成发送请求、接收响应，断开连接

服务器端程序代码：

#encoding:utf-8import socket #导入socket包为了之后使用socket创建TCP服务端信息import sys#导入sys包，为了之后从终端获取参数def main():if(len(sys.argv)<2):print "Usage:<HOST Address> <PORT>"exit(0)else:HOST=sys.argv[1]PORT=int(sys.argv[2])buffsize=1024socket.setdefaulttimeout(100)server=socket.socket(socket.AF_INET,socket.SOCK_STREAM)server.bind((HOST,PORT))server.listen(5)print "[*]Listening on %s:%d"%(HOST,PORT)while True:clientsock,clientaddress=server.accept()print "Connect from:",clientaddresswhile True:recvdata = clientsock.recv(buffsize).decode('utf-8')if recvdata == 'exit':breakprint recvdatasenddata = raw_input("input the message you want to send ")clientsock.send(senddata.encode())clientsock.close()server.close()if __name__ == '__main__':main()

客户端程序代码：

#encoding:utf-8import socketimport sysdef main():if len(sys.argv)<3:print("Usage:<Server Host> <Server Port>")exit()else:HOST=sys.argv[1]PORT=int(sys.argv[2])socket.setdefaulttimeout(10)client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)client.connect((HOST,PORT))while True:senddate=raw_input("input the message you want to send or input exit to quite!")if senddate=='exit':breakclient.send(senddate)recvdata=client.recv(1024).decode('utf-8')print recvdataclient.close()if __name__ == '__main__':main()
