Question

我目前正在编写一个slack / youtube插件，用于将已发布的youtube链接添加到播放列表中。我认为代码还可以，但我刚刚开始，不知道是不是oauth还是我。

这是错误：

 Traceback (most recent call last):
  File "slackapi.py", line 124, in <module>

  File "slackapi.py", line 88, in add_video_to_playlist

Answer 1

404错误表示无法找到站点或API。你将会遇到很多关于API的问题。不幸的是我无法帮助你，因为我没有使用Python和API，只是检查你的请求和发送

Answer 2

找到它。这是代码。我正在将所有输出解析为.lower（），因此视频ID不正确。谢谢你的帮助。

此外，credentials = run(flow, storage)已弃用。它应该是credentials = run_flow(flow, storage)。

为什么我从YouTube API收到错误404“未找到视频”？
