用于访问可汗学院挑战的内部 API
Internal APIs for getting access to Khan Academy Challenges
我正在编写一个与可汗学院集成的应用程序，我想知道是否有人知道如何获得学习者完成的挑战？
例如，我已经登录并完成了以下编程播放列表中的几个挑战。
https://www.khanacademy.org/computing/computer-programming/programming
当我查看页面本身时，它显示一些挑战标记为已完成，但是页面本身的 Chrome 开发者控制台没有显示任何 XHR Api 调用下拉该信息。
所以有没有人发现需要内部 API 才能完成哪些挑战？
根据 Ben Kraft 的建议，我试过：
'/api/v1/user/progress_summary?kind=练习'
并得到：
{"started":[],"complete":["ex8e7aac0b"]}
使用：
'/api/internal/user/kaid_688515334519823186196256/progress?dt_start=2017-08-15T00:00:00.000Z&dt_end=2018-08-25T00:00:00Z'
我有很多数据，但我不知道我可以使用哪些其他参数来归零我想要的信息（已完成 JS 入门课程的挑战）
经过一些调查，我发现了内部 API。路径如下。可以从 public /api/v1/users 调用中找到用户 KAID。 dt_start 和 dt_end 是您希望获得进度的时间范围。
/api/internal/user/[USER KAID]/progress?dt_start=2016-05-13T22:00:00.000Z&dt_end=2016-05-21T00:00:00Z&tz_offset=120&lang=en&_=1463730370107
我希望这对以后的其他人有所帮助。
我认为 /api/v1/user/progress_summary 是你最好的选择。我不确定为什么它没有在 API 资源管理器中列出，但这是内部文档：
Return progress for a content type with started and completed lists.
Takes a comma-separated `kind` param, like:
/api/v1/user/progress_summary?kind=Video,Article
and returns a dictionary that looks like:
{"complete": ["a1314267931"], "started": []}
（您还需要传递一个用户标识符，例如 kaid，类似于其他 /api/v1/user 路由。）这些 ID 应该与您可以从主题树中获得的内容相匹配 API，如果您需要有关各个内容项的更多数据。据我所知，这与我们在主题页面上使用的数据完全相同。
这是 Khan API 示例之一的经过大量修改的版本，它完全符合您的要求（我需要相同的信息）。
