Spotipy：如何将身份验证令牌传递给客户端

问题描述

我正在尝试使用spotipy python库构建一个应用程序来访问Spotify API。

我的OAuth代码如下所示，除了使用正确的auth参数初始化客户端之外，它似乎可以正常工作。

self.sp_auth=spotipy.oauth2.SpotifyOAuth(secrets.sp_auth_id,
                                secrets.sp_auth_pw, secrets.sp_callback_url,
                                scope="playlist-modify-public user-library-read", state=state)

...

url = self.sp_auth.get_authorize_url()

将url发送给用户。 在用户表示她/他已给予许可后： 从Web服务器获取授权码并用于生成令牌。

self.auth_token=self.sp_auth.get_access_token(self.auth_code)

self.auth_Token如下所示：

{'access_token'  : 'BQD ... qE7K3PBZKB6iZFU3_4p', 
 'token_type'    : 'Bearer',
 'expires_in'    : 3600,
 'refresh_token' : 'AQCOS2Xo ... MK09ry7-a-fl61OwhuO1Q',
 'scope'         : 'playlist-modify-public user-library-read',
 'expires_at'    : 1548247835}

然后，我按如下方式初始化SPOTiPY客户端模块：

self.sp = spotipy.Spotify(auth=self.auth_token)

然后我尝试以下操作：

playlists = self.sp.current_user_playlists(limit=10)

这将引发此异常：

Traceback (most recent call last):
File "/usr/local/lib/python3.6/dist-packages/spotipy/client.py", line 119, in _internal_call
    r.raise_for_status()

    raise HTTPError(http_error_msg, response=self)

During handling of the above exception, another exception occurred:

    return self._internal_call('GET', url, payload, kwargs)

    headers=r.headers)
spotipy.client.SpotifyException: http status: 400, code:-1 - https://api.spotify.com/v1/me/playlists?limit=10&offset=0:
 Only valid bearer authentication supported

看起来我没有正确地将令牌传递给恶意客户端。例如，self.sp = spotipy.Spotify(auth="random_bullshit")给了我相同的例外。我还尝试像这样传递令牌auth=self.auth_token['access_token']，结果相同。文档并没有明确说明auth参数应该是什么，我也没有真正理解source code。但我要说的是，这表明auth=self.auth_token['access_token']是正确的。

谢谢！

解决方案

正如我在上一次编辑中所建议的auth=self.auth_token['access_token']是正确的，我只是其中有一个打字错误。无论如何，由于文档中没有太多关于auth参数的内容，这可能会对某些人有所帮助。
