Youtube 调试信息字段详细信息

Question

我只是在对 youtube 视频细节进行研发。当我们在 youtube 中播放视频时，如果我们右键单击，我们可以看到一个选项称为复制调试信息。如果我们复制它，那么会有很多字段如下所示，我只是想知道下面这些字段的详细信息。

例如 - docid filed 以 youtube 的视频 ID 为人所知。像那样我想知道其他领域的细节。如果有人可以帮助我，那就太好了..

Answer 1

我怀疑是否有一种简单的方法可以做到这一点 - (AFAIK，没有 YouTube 数据 API 公开这样的值)，但是，如果你真的想检查，你可以输入 view-source:https://www.youtube.com/watch?v=<VIDEO_ID> - 哪里<VIDEO_ID>是 YouTube 视频的 ID。

有一些值是从 copy debug info 中获得的- 但不是全部，我担心。
