我一直在使用以下方法来检索包含在特定YouTube播放列表中的所有视频id，标题和默认缩略图图像，以便在动态播放列表轮播中使用(然后将id传递给用于动态创建缩略图轮播的数组)。注意'playlist'变量是通过一个外部化的XML值定义的):
// Get YouTube Playlist values
var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/' + playlist + '?v=2&alt=json&callback=?';
var videoURL = 'http://www.youtube.com/watch?v=';
$.getJSON(playListURL, function(data) {
var list_data = "";
$.each(data.feed.entry, function(i, item) {
var feedTitle = item.title.$t;
var feedURL = item.link[1].href;
var fragments = feedURL.split("/");
var videoID = fragments[fragments.length - 2];
var thumb = ""+ videoID +"/sddefault.jpg";
if (videoID !='videos') {
yt_videos.push(videoID);
}
yt_thumb.push(thumb);
yt_title.push(feedTitle);
});
$(list_data).appendTo(".cont");
populateCarousel();
});
YouTube已经弃用了v1-2 api，该方法不再工作。YouTube API v3是否提供了一个等效的方法?特别是替换调用:
var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/' + playlist + '?v=2&alt=json&callback=?';
您需要切换到新的PlaylistItems/list端点来从播放列表中获取视频信息。

items数组中每个对象的id值应该是您想要的videoId值
api_key = 'YOUR_API_KEY'
api_service_name = 'youtube'
api_version = 'v3'
playlist_id = 'SOME_PLAYLIST_ID'
# build a connected client
youtube = googleapiclient.discovery.build(api_service_name, api_version, developerKey=api_key)
# make a request (note, only the 'snippet' part has been requested)
request = youtube.playlistItems().list(part=['snippet'], playlistId=playlist_id)
response = request.execute()
# scrape out the actual video ids (probably could be safer)
for (k, v) in response.items():
if(k == 'items'):
video_ids = [pli['snippet']['resourceId']['videoId'] for pli in v if pli['snippet']['resourceId']['kind']=='youtube#video']
print(video_ids)
