关于 [ VPN2 ] :
就如 URI 中所写的那样，VPN2 只是一个类似反向代理的玩意。
由于学校网站配置千奇百怪，有时会遇到只有在校园网中才能访问的情况。这时可以使用 VPN2。
使用 `360SO via VPN2` 搜索要访问的网址。记得加上 `http / https` 前缀。
搜索结果页出现“找不到该 URL，可以直接访问 `http://x.x`”后点击直接访问链接即可。
遇“无效网关”等奇怪错误时，请检查协议前缀是否正确，如 http 可能误写为 https。
当前（20220110）VPN2 似乎不支持流式传输，因而下载大文件可能出错，记得校验 Hash。

关于 [ 健康打卡 ] :
新版（20220420）健康打卡报表使用 Hash Router，各跳转关系十分混乱且不稳定。
为简化实现，当且仅当访问上文指定的地址时才可使用一键打卡功能。
直接 Post 请求进行打卡的实现在本目录下的 health-check-in.js 中，感兴趣的可以尝试。

如果 [ 教务系统提示 非法访问 ] :
相信自己，你并没有做错什么。这时候你可以清除 Cookie，SessionStorage 等数据。
当然 Cookie 会自动过期，所以和跳大神治麻疹一样，随便用点什么“独门秘籍”，过一阵子也就自己好了。

如果 [ 密码错误 ] :
只需将 [ just123456, 123456, <身份证后六位> ] 排列组合即可。

关于 [ 校园网 ] :
