深信服上网认证

1、每次重启电脑或者每天都会重定向到网络认证页面

http://1.1.1.3/ac_portal/disclaimer/pc.html

2、依赖安装

pip install requests -i https://pypi.doubanio.com/simple

3、使用python脚本自动化认证网络

4、安装pyinstaller库，打包成exe程序，将生成的auth_net.exe文件放入C:\Windows目录

pip install pyinstaller
pyinstaller -F auth_net.py
#生成dist/auth_net.exe

首次运行需要输入用户名密码进行认证，因此需要手动打开程序输入

后续脚本将账户信息保存配置文件到C:\Windows目录，后续不需要再重新输入认证信息（除非删除WindowsC:\Windows目录的配置文件user_account.json）

5、创建Windows任务计划程序

6、程序运行结果，每次开机自启动
