Question

我想创建一个使用Spotipy从Spotify播放列表中编译曲目URI列表的函数。我编写的函数现在可以正常工作，只是返回了太多信息，而我对如何过滤出想要的内容感到困惑。

我尝试索引结果本身，并在sp.user_playlist_tracks（）函数中弄乱了field参数，但是似乎没有什么仅返回轨道URI。

下面的函数从'playlist_id'参数指定的Spotify播放列表中捕获所有曲目：

def get_playlist_tracks(auth_client, username, playlist_id):
    # Ref - https://stackoverflow.com/questions/39086287/spotipy-how-to-read-more-than-100-tracks-from-a-playlist?noredirect=1&lq=1
    results = sp.user_playlist_tracks(username,playlist_id)
    tracks = results['items']
    while results['next']:
        results = sp.next(results)
        tracks.extend(results['items'])
    return tracks

该函数以JSON格式返回对象列表：

有人知道如何索引返回结果以仅获取跟踪URI吗？还是知道如何使用field参数仅获取轨道URI？我浏览了Spotify API和Spotipy文档，但似乎没有任何答案可以回答这个特定问题。

Answer 1

我想我明白了！当循环遍历“结果”中的每个项目时，可以使用item ['track'] ['uri']为轨道URI编制索引。这是我更新的get_playlist_tracks（）函数，该函数将忽略所有获取的本地轨道，并将发现的URI附加到数组中：

def get_playlist_tracks(auth_client, username, playlist_id):
    # Ref - https://stackoverflow.com/questions/39086287/spotipy-how-to-read-more-than-100-tracks-from-a-playlist?noredirect=1&lq=1
    results = sp.user_playlist_tracks(username,playlist_id)
    playlist_items = results['items']
    uris = []

    while results['next']:
        results = sp.next(results)
        playlist_items.append(results['items'])

    for item in playlist_items:
        is_local = item["is_local"]
        if is_local == True: # Filtering out any local tracks (i.e. not hosted by Spotify)
            continue
        else:
            track_uri = item["track"]["uri"]
            uris.append(track_uri)
    return uris
