如何以docs.google.com的形式获取youtube流网址

Question

互联网上有一些网站使用VideoJs播放器播放来自youtube的视频。当你看看他们的源代码时，就会显示出这样的东西。

我确定它不是谷歌驱动视频。它的YouTube视频，但他们是从docs.google.com而不是googlevideos.com播放它。他们是如何得到这个链接的？

任何人都可以帮助我。我出于某种原因需要这个。

Answer 1

这很容易。只需将youtube下载网址中的googlevideo.com替换为c.docs.google.com

即可

感谢您提出这个问题。经过一段时间的搜索我就知道了。
