# 2020/5/20 重要更新：修复登录过程，移除验证码（不需要），优化代码格式，感谢giteee及时反馈。
# 2020/5/28 更改为使用自动获取学校URL的方式，更改为使用参数形式，添加另一种登录形式AuthServer的支持(已完成但未测试)。感谢柠火的反馈。
# 2020/6/1 修复BUG，发现AuthServer的登录方式每个学校都不一样。支持任意表单内容自定义（详情见输出信息和formdb/1129.json）。感谢涅灵的反馈。
# 2020/6/2 AuthServer的登录网址不再使用硬编码的方式，理论上能支持所有学校了吧？感谢涅灵的反馈。
# 2020/6/17 修复crontab使用中相对路径的问题。识别form特征。
# 2020/7/5 浪费别人的时间是一种可耻的行为。
