主要刷课API
URL：https://course.icve.com.cn/learnspace/course/study/learningTime_saveVideoLearnDetailRecord.action
请求方式：Post
参数：
limitId: 包含在网页的javascript中，每次刷新页面limitId也会刷新，可重复用
studyRecord： 通过crypto-js AES加密的一串数据，包含课程ID，视频ID，以及学习时长，学习起始秒数和学习结束的秒数。
返回结果：”保存状态成功“或者“参数不合法，超出时长”，学习时长越长，需要等待一定时间才能第再次保存学习状态。学习时长短不需要等待。
获取limitId
URL:https://course.icve.com.cn/learnspace/learn/learn/templateeight/index.action?params.courseId=26ae32dc2dcd4c9cbace10894d9a172b___¶ms.templateType=8¶ms.templateStyleType=0¶ms.template=templateeight¶ms.classId=¶ms.tplRoot=learn
请求方式： Get
参数：url里面可以看到，主要包含一个课程id，其他的似乎默认就行,可以去浏览器里找到对应的url
返回结果：内容是html网页，直接通过正则搜索找到limitId
studyRecord AES加密的学习状态参数
官方加密功能函数和格式化函数的js文件URL: https://course.icve.com.cn/learnspace/resource/common/js/CommonUtil.js?v=2022042401。
studyRecord参数就是将数据格式化后序列化再进行AES加密得到的字符串
主要的参数就只有courseId,itemId,stratTime,endTime:
courseId: 代表当前学习课程的16进制id
itemId: 对应课程中的每个视频或者文档也有一个16进制id
startTime: 对应视频时长进度
endTime: 对应视频的时长，表示当前视频从startTime秒学习到了endTime的秒数
文档内容完成学习API
url:https://course.icve.com.cn/learnspace/course/study/learningTime_saveCourseItemLearnRecord.action
参数：课程id，视频id，其他的参数固定即可
获取itemId
url:https://course.icve.com.cn/learnspace/learn/learn/templateeight/courseware_index.action?params.courseId=26ae32dc2dcd4c9cbace10894d9a172b___
返回的html中包含itmeId，可以通过beautifulsoup搜索id=spoint.* 获得对对应的标签
判断内容是否已经完成
url:https://course.icve.com.cn/learnspace/learn/learnCourseware/getSingleItemCompleteCase.json
返回json,completed等于1表示学习完成，2表示部分学习，0表示内容没有学习过。
效果图
完整py+nodejs代码
py需要安装库: requests bs4
nodejs需要安装库: crypto-js
自行替换python代码中的Cookie，test.js主要是做参数加密，运行python文件即可
