我没有看到一个完整的很多信息current_user_playing_track()的Spotipy，所以希望有人能够帮助我在这方面。

import spotipy
import spotipy.util as util
from spotipy.oauth2 import SpotifyClientCredentials
from spotipy.oauth2 import SpotifyOAuth
import json
import requests

cid = 'my client id'
secret = 'my client secrets'
redirect_uri = 'http://localhost:7777/callback'
username = 'my username'
scope = 'user-read-currently-playing'
token = util.prompt_for_user_token(username, scope, cid, secret, redirect_uri)
spotify = spotipy.Spotify(token)

def get_current_song():
    # Get track information
    track = spotify.current_user_playing_track()
    print(json.dumps(track, sort_keys=True, indent=4))
    artist = json.dumps(track['item']['album']['artists'][0]['name'])
    track = json.dumps(track['item']['name'])

    return artist, track

def main():
    artist, track = get_current_song()
    if artist !="":
        print("Currently playing " + artist + " - " + track + "--TRACK ID--")

if __name__ == '__main__':
    main()

这工作没有麻烦，但我想要的轨道ID，这样我就可以使另一个函数来分析音频，但当我添加这个

def get_current_song():
    # Get track information
    track = spotify.current_user_playing_track()
    print(json.dumps(track, sort_keys=True, indent=4))
    artist = json.dumps(track['item']['album']['artists'][0]['name'])
    track = json.dumps(track['item']['name'])
    track_id = json.dumps(track['item']['id'])
    return artist, track

我得到这个错误
