Spotify 刷新令牌 Python

Question

我有一个 python 程序，可以 returns 我目前正在听的任何歌曲。我从 Spotify API 获得的访问令牌只持续一个小时，我很难找到一种简单的方法在我的代码中实现刷新令牌。

    SPOTIFY_GET_CURRENT_TRACK_URL = 'https://api.spotify.com/v1/me/player'
SPOTIFY_ACCESS_TOKEN = 'BQBQMLkkLb6az9TRv-PDXFFcm4KHrofc67H12Uzs3FXaPWHETy4ivnC-WGu2Jg5wlZ_yhggGypiO0Gnv_QkNGkefTuCjNR_Tzjw4pv2W9f_9_D7-LfD2W5KVPzh2DxMmf9TNPpSn200D_Xd4AD8F_MeJc-DIlA'

#Method to return the info for the currently playing track
def get_current_track():
    response = requests.get(
        SPOTIFY_GET_CURRENT_TRACK_URL,
        headers = {
            "Authorization": f"Bearer {SPOTIFY_ACCESS_TOKEN}"
        }
    )
    resp_json = response.json()

    track_id = resp_json['item']['id']
    track_name = resp_json['item']['name']
    artists = resp_json['item']['artists']
    artists_name = ', '.join(
        [artist['name'] for artist in artists]
    )
    link = resp_json['item']['external_urls']['spotify']

    current_track_info = {
        "id" : track_id,
        "name" : track_name,
        "artists" : artists_name,
        "link" : link
    }

    return current_track_info

如何使用 class 来保留令牌，然后在令牌过时时再次请求？像这样：

class SpotifyTracker:
    TRACK_URL = 'https://api.spotify.com/v1/me/player'

    def __init__(self):
        self._token = self._set_token()

    def _set_token(self):
        # ... logic to set token

    def _request_track_data(self):
        return requests.get(
            self.TRACK_URL,
            headers={
                "Authorization": f"Bearer {self._token}"
            }
        )

    def get_current_track(self):
        response = self._request_track_data() 
        if response.code == 401:
            self._set_token()
            response = self._request_track_data()
        resp_json = response.json()
        ...
        return current_track_info
