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，生产auth_net.exe

pip install pyinstaller
pyinstaller -F aaaa.py
#生成dist/aaaa.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到配置文件不需要再认证（除非删除Windows临时目录内的配置文件C:\Users\wsq\AppData\Local\Temp\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
