## 适用https://icve-mooc.icve.com.cn/cms/

### 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___&params.templateType=8&params.templateStyleType=0&params.template=templateeight&params.classId=&params.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

!(https://raw.githubusercontent.com/kkkbbb/tuchuang/master/uPic/image-20221110175244805.png)

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

!(https://raw.githubusercontent.com/kkkbbb/tuchuang/master/uPic/image-20221110205007663.png)

### 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=s_point_.* 获得对对应的标签

!(https://raw.githubusercontent.com/kkkbbb/tuchuang/master/uPic/image-20221110204525033.png)

### 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。

### 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

用cookie登录或者账号密码,之后在哪里更改课程？ID

你可以直接在python代码里面搜索courseid,然后替换成你的课程的id。课程id打开学习页面直接在源码中搜索courseid能找到
