引言
俗话说吃水不忘挖井人，在这给一位大佬博主引流一波，我的代码思想都是基于这篇文章，所有的配置和环境都是以这篇博客为基础。
点这里速看
重点：跟着上面这个博客配置好环境，进行下面工作才有意义
本章博客代码实现的功能：
多个用户预约同一个位置的不同时间段
基于推荐博客的不同

config.ini
config.ini 里面的账号有两个条件需要满足:
- 能登录这个链接.
- 能登录seat软件(主要是用于手动签到)
[Basic]
;图书馆：eg(南校区第二图书馆)
LIBRARY_ADDR = library
;楼层：eg(南校区第二图书馆6层)
LIBRARY_FLOOR = floor
;房间 eg(6层社会科学类借阅区(Ⅱ))
LIBRARY_ROOM = room
;位置 eg(002) 注意座位号一定要三位
LIBRARY_SEAT = seat
[API]
;百度智能云 文字识别OCR AK
API_KEY = your_api_key
;百度智能云 文字识别OCR SK
SECRET_KEY = your_secret_key
[User]
;昵称: ['账号', '密码', '使用起始时间', '结束时间']
sample_user1: ['username1', 'password', '8:00', '12:00']
sample_user2: ['username2', 'password', '15:00', '19:00']
[ToEmail]
;发信人的邮箱账号
SENDER_EMAIL = sender email
;发送邮箱的授权码
SENDER_PASS = your send email of authorization code
;收件人的邮箱账号
RECEIVE_EMAIL = your recipient email
关于邮箱那段配置可以自行百度解决的，我在这不赘述了(eg:百度 QQ邮箱授权码)
其他配置
自动启动时间设置为每日晚上七点半，其余步骤还有代码都是一样的，如果用以上代码抢占一些不热门的座位到这就可以结束了，毕竟比手动抢座位快点。
对于程序运行时间的个人看法
本章博客的代码有点冗余，需要改进，当你放到Coding运行时，你会发现时间运行稍长，可能你程序开始运行了，座位已经被占了(本人遇到过，为了图书馆占座和谐，本章代码只是第一次的雏形代码)，在改善时间方面，抛砖引玉，给出几个思考的方向：
- python中可以多进程运行代码，具体实现可以百度学习一下
- 卡时间，让程序提前一分钟运行，把所有的东西(eg:data)都准备好，等到七点半立刻把表单数据提交出去
- 理解session和cookie的作用，这里是改善代码的关键，和上面两个思路结合(待完善)
个人开发工具：
- VS code；
- VS(主要用于测试python并行测试，VS code应该也可以，个人能力水平有限，没找到相关文章)
- postman(主要用于测试网页post、get请求)
- 浏览器自带的F12(查看URL和表单传递数据等)
