Spotipy无效用户名？

Question

我有一个抽搐机器人的一个流线，我知道，我正在尝试做一个命令，显示他目前正在听的歌曲在spotify。

我找到了这样做的Spotipy库，但是使用以下代码我得到了一个无效的用户名错误：

import spotipy
import spotipy.util as util

CLIENT_ID = 'xx'
CLIENT_SECRET = 'xx'

token = util.oauth2.SpotifyClientCredentials(client_id=CLIENT_ID, client_secret=CLIENT_SECRET)

cache_token = token.get_access_token()

sp = spotipy.Spotify(cache_token)
currentsong = sp.currently_playing()

print(currentsong)

当然，在我的代码中，我填写了凭证。因此，这段代码返回了以下错误：

Traceback (most recent call last):
  File "/Users/Pascalschilp/Documents/spot/spotipy-master/lol.py", line 13, in <module>
    currentsong = sp.currently_playing('spotify:user:passle')
  File "/Users/Pascalschilp/Documents/spot/spotipy-master/spotipy/client.py", line 899, in currently_playing
    return self._get("me/player/currently-playing", market = market)
  File "/Users/Pascalschilp/Documents/spot/spotipy-master/spotipy/client.py", line 148, in _get
    return self._internal_call('GET', url, payload, kwargs)
  File "/Users/Pascalschilp/Documents/spot/spotipy-master/spotipy/client.py", line 126, in _internal_call
    headers=r.headers)
spotipy.client.SpotifyException: http status: 404, code:-1 - https://api.spotify.com/v1/me/player/currently-playing?market=spotify%3Auser%3Apassle:

[dir: /Users/Pascalschilp/Documents/spot/spotipy-master]
[path: /usr/bin:/bin:/usr/sbin:/sbin]

我不太清楚为什么会出错。谁能给我指明正确的方向？

另外/或者:如何使用请求库进行承载身份验证？(我尝试用postman手工完成请求，并填写客户ID，它给了我一个错误："message"：“只支持有效的承载身份验证”)

Answer 1

不要使用这种授权形式。您遇到这种情况的原因是您正在进行匿名API调用。此方法需要oAuth授权才能进行这些调用。设置用户名和适当的作用域：

username = "myUsername"
scope = "user-read-currently-playing"

您需要应用程序的重定向URI：

redirect_uri = "http://localhost:8888/callback/"

将令牌设置为：

token = util.prompt_for_user_token(username, scope, CLIENT_ID, CLIENT_SECRET, redirect_uri)

现在您可以实例化Spotify对象了。

sp = spotipy.Spotify(auth=token)

你应该做得很好。一个窗口将弹出，提示您验证自己，但之后，它将不再必要，因为它将在缓存中。

为了让它正常工作，您可以提取这样的数据：

song_name = currentsong['item']['name']
song_artist = currentsong['item']['artists'][0]['name']
print("Now playing {} by {}".format(song_name, song_artist))
