使用 Python 中的 YouTube Data API v3 将视频上传到 YouTube 并将其添加到播放列表

Question

借助Example code 中给出的示例，我编写了一个脚本来使用 Python 中的 YouTube Data API v3 将视频上传到 YouTube。

我编写了另一个脚本，使用相同的 YouTube Data API v3 将上传的视频添加到播放列表中，您可以看到 here

之后，我编写了一个脚本来上传视频并将该视频添加到播放列表中。在我处理身份验证和范围的过程中，我仍然收到权限错误。这是我的新脚本

我无法弄清楚出了什么问题。我收到权限错误。两个脚本都可以独立工作。

谁能帮我找出我错在哪里或如何实现上传视频并添加播放列表。

Answer 1

我得到的答案实际上在两个独立的脚本范围内是不同的。
上传范围为“https://www.googleapis.com/auth/youtube.upload”
添加到播放列表的范围是“https://www.googleapis.com/auth/youtube”

因为范围不同，所以我不得不单独处理身份验证。
