使用Spotify Web API开发歌曲推荐项目时遭遇403错误求助

我正在开发一个Spotify歌曲推荐项目，调用audio_features接口时持续出现403错误，无法正常获取歌曲音频特征。以下是项目代码及报错信息：

可能的解决方法 #

• 检查权限范围：虽然获取音频特征无需特定用户权限，但建议补充权限范围并重新授权。更新scope为：

  scope = "user-library-read playlist-read-private user-read-playback-state"
  

  之后删除本地生成的.cache缓存文件，重新运行代码完成授权。

• 核对Redirect URI：确保代码中SPOTIPY_REDIRECT_URI的值与Spotify开发者后台应用设置的完全一致，包括协议（http/https）、端口及结尾斜杠。

• 重置授权缓存：删除本地的.cache文件，强制重新获取有效授权token。

• 检查网络环境：确认网络可直接访问Spotify API，若处于受限网络环境，需调整网络设置。

• 切换授权流程：由于音频特征属于公开数据，可改用Client Credentials Flow，无需用户授权和redirect URI：

  from spotipy.oauth2 import SpotifyClientCredentials
  
  sp = spotipy.Spotify(auth_manager=SpotifyClientCredentials(
      client_id=SPOTIPY_CLIENT_ID,
      client_secret=SPOTIPY_CLIENT_SECRET
  ))
