南京大学教务网抢课系统 2 | 3 | #### 工具依赖 4 | 脚本中使用了一些python库，主要有 5 | - requests 6 | - beautifulsoup 7 | 8 | 可以使用pip进行安装 9 | ``` 10 | pip install requests 11 | pip install bs4 12 | ``` 13 | 如果发现有其他依赖缺失，按提示自行安装即可 14 | 15 | #### 使用方法 16 | 默认检查是否存在用户信息配置文件，如果不存在，则需要手动输入 17 | 之后需要输入验证码进行验证，验证码会自动弹出，同时默认保存在脚本所在目录中，输入后图片自动删除 18 | 登陆成功后，输入对应年级，可以获取该年级的专业课程列表 19 | 之后输入对应课程的序号（非课程号），即可开始抢课 20 | 21 | #### 支持Cookie登录 22 | 首次登陆后一段时间内可免验证登录，一段时间不进行操作后登录会失效，需要重新登陆 23 | 24 | #### 配置文件 25 | 使用该软件登陆系统可以使用配置文件存储用户信息避免重复输入 26 | 在根目录下创建user.cfg，格式如下 27 | ``` 28 | userName:181220000 29 | password:abcDEF 30 | ``` 31 | 32 | #### 注意事项 33 | 脚本中GrabCourse函数接受一个参数控制抢课时间间隔，为避免对教务网造成过大压力，建议间隔在5分钟以上，频率过高有概率导致封号，后果自负 34 | -------------------------------------------------------------------------------- /login.py:
