 1 | # BUAAGetCourse
 2 | 用来蹲北航教务给课程扩容的名额，解放双手双眼
 3 | 
 4 | (换课请联系教务进行换课 小心截胡）
 5 | 
 6 | 
 7 | 第一版grabcourse.py是用Selenium登陆 用requests选课
 8 | 
 9 | 第二版xuanke.py参考了[北航教务一键评教版本](https://github.com/bearbattle/buaa-teacher-evaluation)将登陆部分更新 不再需要Selenium 仅使用requests 更方便使用
10 | 
11 | `username`和`password`即账号和密码
12 | 
13 | `type`是想选课的类型（一般专业课 核心专业课 核心通识课 一般专业课）
14 | 
15 | `course`为想选的课程编号
16 | 
17 | `rwh`的末尾默认为001  在相同课程编号有不同老师（应该只有核心专业课用到）想选同名课程的第n个则改为00n  (关于核心专业课同名有多课情况建议F12使用element或者network抓选课包查看一下最保险)
18 | 
19 | **grabcourse.py在2021年秋季学期测试过可正常使用**
20 | 
21 | **xuanke.py在2022年春季学期测试过可正常使用**
