python - Spotipy:如何从播放列表中读取超过 100 首轨道

Question

我正在尝试使用 Spotipy library 提取特定播放列表中的所有轨道对于 python 。

user_playlist_tracks 函数限制为 100 个轨道，无论参数限制如何。 Spotipy 文档将其描述为:

user_playlist_tracks(user, playlist_id=None, fields=None, limit=100, offset=0, market=None)

Get full details of the tracks of a playlist owned by a user.

Parameters:

• user
• the id of the user playlist_id
• the id of the playlist fields
• which fields to return limit
• the maximum number of tracks to return offset
• the index of the first track to return market
• an ISO 3166-1 alpha-2 country code.

在使用 Spotify 进行身份验证后，我目前正在使用这样的东西:

username = xxxx
playlist = #fromspotipy
sp_playlist = sp.user_playlist_tracks(username, playlist_id=playlist)
tracks = sp_playlist['items']
print tracks

有没有办法返回超过 100 首轨道？我试过在函数参数中设置 limit=None，但它返回错误。

许多 spotipy 方法返回分页结果，因此您必须滚动浏览它们才能查看超过最大限制的内容。我在收集播放列表的完整轨道列表时最常遇到这种情况，因此创建了一个自定义方法来处理此问题:

def get_playlist_tracks(username,playlist_id):
    results = sp.user_playlist_tracks(username,playlist_id)
    tracks = results['items']
    while results['next']:
        results = sp.next(results)
        tracks.extend(results['items'])
    return tracks
