當我決議從 Spotify 的“用戶保存的曲目”端點收到的 JSON 時，我在將 id 附加到單獨的串列時遇到了麻煩。
收到的 JSON 如下所示：
{
"href": "https://api.spotify.com/v1/me/tracks?offset=0&limit=20",
"items": [
{
"added_at": "2021-11-16T13:56:51Z",
"track": {
"album": {
"album_type": "single",
"artists": [
{
"external_urls": {
"spotify": "https://open.spotify.com/artist/3iKDeO8yaOiWz7vkeljunk"
},
"href": "https://api.spotify.com/v1/artists/3iKDeO8yaOiWz7vkeljunk",
"id": "3iKDeO8yaOiWz7vkeljunk",
"name": "Heavenward",
"type": "artist",
"uri": "spotify:artist:3iKDeO8yaOiWz7vkeljunk"
}
],
"available_markets": [
],
"disc_number": 1,
"duration_ms": 224838,
"explicit": false,
"external_ids": {
"isrc": "QZK6P2040977"
},
"external_urls": {
"spotify": "https://open.spotify.com/track/6mJ1nbmQOm6iNClo71K5O6"
},
"href": "https://api.spotify.com/v1/tracks/6mJ1nbmQOm6iNClo71K5O6",
"id": "6mJ1nbmQOm6iNClo71K5O6",
"is_local": false,
"name": "Hole",
"popularity": 33,
"preview_url": "https://p.scdn.co/mp3-preview/c425dc91bdb19f1cddf2b35df08e30a03290c3c0?cid=8c9ee97b95854163a250399fda32d350",
"track_number": 1,
"type": "track",
"uri": "spotify:track:6mJ1nbmQOm6iNClo71K5O6"
}
}
現在我用來決議的代碼如下所示：
def getLikedTrackIds(session):
url = 'https://api.spotify.com/v1/me/tracks'
payload = makeGetRequest(session, url)
if payload == None:
return None
liked_tracks_ids = []
for track in payload['items']:
for attribute in track['track']:
if (attribute == 'id'):
app.logger.info(f"\n\nTrack ID: {attribute}")
liked_tracks_ids.append(attribute)
return liked_tracks_ids
對于每首歌曲，我的 like_track_ids 都填充了字串“id”：
[ "id", "id", "id", "id"....]
任何人都可以提供有關我做錯了什么的見解嗎？
uj5u.com熱心網友回復：
已經在問題下進行了評論，但可以通過擺脫回圈來簡化您的代碼：
def getLikedTrackIds(session):
url = 'https://api.spotify.com/v1/me/tracks'
payload = makeGetRequest(session, url)
if payload == None:
return None
liked_tracks_ids = []
for track in payload['items']:
liked_id = track['track'].get('id', None)
if liked_id:
app.logger.info(f"\n\nTrack ID: {liked_id}")
liked_tracks_ids.append(liked_id)
return liked_tracks_ids
