python - 每次我尝试从 PYTUBE 下载官方视频时都会显示此错误

问题描述

这是我尝试下载任何官方视频时总是遇到的错误，但在使用某些在线下载应用程序时会下载相同的视频。

  KeyError    Traceback (most recent call last)
~\anaconda3\lib\site-packages\pytube\extract.py in apply_descrambler(stream_data, key)
--> 297                 for format_item in formats
~\anaconda3\lib\site-packages\pytube\extract.py in <listcomp>(.0)
    296                 }
--> 297                 for format_item in formats
    298             ]
KeyError: 'url'

During handling of the above exception, another exception occurred:

KeyError: 'cipher'

所以任何人都可以帮助我解决这个错误

解决方案

我也有同样的问题。我通过这样做解决了它：

  1. 转到安装site-packages/pytub/extract.py位置pytube。
  2. 找到这条线：parse_qs(formats[i]["cipher"]) for i, data in enumerate(formats)
  3. 替换["cipher"]为["signatureCipher"]
  4. 完毕。
