用此命令也能成功，并且更快捷。
curl http://p.nju.edu.cn/portal_io/login?username=学号&password=密码 # curl: 客户端(client)的 URL 工具

需要注意要及时登出 log, 否则会一直扣费，账户余额为 0.
在这条语句中设置登出 log
parser.add_argument('-do', type=str, default='l', help='用来指定登录login，登出logout和查询')

or

分别使用如下脚本命令利用 parser 设置参数进行登录或退出。

python NJU_WLAN_connect.py -do l   # log in 
python NJU_WLAN_connect.py -do o   # log out
