Question

我正在尝试使用Spotipy方法删除重复出现的音轨（因此删除重复项）。但是该功能似乎无效。 Spotify API调用返回的错误是没有授权令牌。
Spotify API返回错误：

{
  "error": {
    "status": 401,
    "message": "No token provided"
  }
}

Python的错误：

  File "C:\Users\Dylan\Documents\PythonProjects\PlaylistTransfer\Spotify.py", line 87, in remove_all_duplicate_tracks
    sp.user_playlist_remove_specific_occurrences_of_tracks(username, playlist_id, tracks)
  File "C:\Users\Dylan\Documents\PythonProjects\PlaylistTransfer\venv\lib\site-packages\spotipy\client.py", line 539, in user_playlist_remove_specific_occurrences_of_tracks
    payload=payload)
  File "C:\Users\Dylan\Documents\PythonProjects\PlaylistTransfer\venv\lib\site-packages\spotipy\client.py", line 183, in _delete
    return self._internal_call('DELETE', url, payload, kwargs)
  File "C:\Users\Dylan\Documents\PythonProjects\PlaylistTransfer\venv\lib\site-packages\spotipy\client.py", line 124, in _internal_call
    headers=r.headers)
spotipy.client.SpotifyException: http status: 400, code:-1 - https://api.spotify.com/v1/___________________________/tracks:
 Could not remove tracks, please check parameters.

这是我的代码：

def remove_all_duplicate_tracks(playlist_id, token):
    sp = spotipy.Spotify(token)
    username = get_username(token)
    existing_tracks = get_track_uris_for_playlist(playlist_id, token)
    duplicate_counter = Counter(existing_tracks)
    tracks = []
    for uri, count in duplicate_counter.items():
        count = count-1
        if count > 0:
            # hard coded position as 1 for testing...
            positions = [1]
            #positions = [x for x in range(1, count+1)]
            track_dict = {"uri": uri, "positions": positions}
            tracks.append(track_dict)
    sp.user_playlist_remove_specific_occurrences_of_tracks(username, playlist_id, tracks)

“曲目”包含以下内容：
[{'uri': '6jq6rcOikCZAmjliAgAmfT', 'positions': [1]}, {'uri': '3tSmXSxaAnU1EPGKa6NytH', 'positions': [1]}, {'uri': '7jeI6EdY0elPSNz80mAKS8', 'positions': [1]}]
我测试了其他方法get_username()和get_track_uris_for_playlist，它们返回了您期望的值并且正在运行。

Answer 1

尽管这个答案来得太晚了，但它是必要的，因为1）这个问题没有解决，2）我相信它将对遇到类似问题的人有所帮助。

首先，您应该将问题限制在特定问题上，这是通过调用sp.user_playlist_remove_specific_occurrences_of_tracks()函数产生的授权错误。这将使问题更加清楚。（以这种方式，必须挖掘代码以找到“热点”！另外，有关音轨的细节也会增加混乱。）

因此，我将答案仅局限于问题，并建议使用以下代码作为基础：

# Data
username = (your username)
playlist_id = (playlist id)  # The ID of the playlist containing the tracks to be deleted
track_ids = [(track_id), (track_id), ...]  # List of track IDs to delete

# Authorization process
scope = "playlist-read-private"
token = spotipy.util.prompt_for_user_token(username, scope=scope)
sp = spotipy.Spotify(auth=token)

# Call the track deletion function
sp.user_playlist_remove_all_occurrences_of_tracks(username, playlist_id, track_ids)

我自己正在使用此过程。我已经使用我的数据尝试了上面的代码，它也对您有用。

Answer 2

您正在尝试更改用户数据：

Could not remove tracks, please check parameters.

传递有效范围，例如：

playlist-modify-public

playlist-modify-private

有关范围的更多信息：https://developer.spotify.com/documentation/general/guides/scopes/

import spotipy
import spotipy.util as util

scope = 'playlist-modify-public playlist-modify-private'

token = util.prompt_for_user_token(username, scope)

if token:
    sp = spotipy.Spotify(auth=token)
    results = sp.current_user_saved_tracks()
    for item in results['items']:
        track = item['track']
        print track['name'] + ' - ' + track['artists'][0]['name']
else:
    print "Can't get token for", username
