出头科技九江学院刷课脚本

注意！此脚本仅用于技术交流，不得欺骗刷课，不得构造攻击！
更不得卖钱！我看不起你！

使用方法
1.安装python环境
2.使用pip命令安装requests库  pip install requests
3.运行这个脚本  python chutou.py 或者是 python3 chutou.py
4.输入用户名 回车 输入密码 回车

写这个代码的初心是为了帮朋友，在网上找了个用户脚本发现用不了，追到他qq群发现软件要收费。然后别的渠道是50一学期的课，就好奇这么点玩意怎么好意思收费！
于是就花了一个晚上，大概是九点钟抓包，九点半摆烂进群求软件，发现收费开始认真研究。凌晨一点代码就写完了。
不得不说，chatGPT极大地帮助了我。根据我的描述出框架，根据每一个环节的请求和返回的响应完善每个函数代码。
大概逻辑就是登录拿到key，获取课程列表拿到课程code，获得课程视频的code，然后发送保存视频播放进度的请求。循环！循环！
代码简陋，能用就行。没有tryexcept，没有加速，没有多线程，就图一个省事和安全
