检索播放列表中包含的视频ID-YouTube API v3

我一直在使用以下方法检索特定YouTube播放列表中包含的所有视频ID、标题和默认缩略图图像，以便在动态播放列表转盘中使用（然后将ID传递给一个数组，该数组用于动态创建缩略图转盘。注意，“playlist”变量是通过外部化的XML值定义的）：

YouTube已经对v1-2 API进行了删减，并且该方法的工作时间更长。YouTube API v3是否提供了等效的方法？具体替换调用：

var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/' + playlist + '?v=2&alt=json&callback=?';

您需要切换到新的端点才能从播放列表中获取视频信息

请求：

HTTP GET: GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2C+id&playlistId=PLCJLiJ8uSJrCpxwz4lmnz1NvvF2SzXbhk&key={YOUR_API_KEY}

响应（对于id=PLCJLiJ8uSJrCpxwz4lmnz1NvvF2SzXbhk）：

---

items

数组中每个对象的

id

值应该是您想要的

videoId

值。

事实上，看起来id不是视频id:/n您不能只获取播放列表项id并像

https://www.youtube.com/watch?v={{video_id}

事实上，您可以在

item.index.contentDetails.videoId

节点中找到您的id。如何获取包含播放列表id和索引号的视频详细信息？参加聚会时迟到，遇到同样的问题：items.id表示播放列表项的id，而不是视频（播放列表项是嵌入视频的容器）。对于视频id，只需使用items.snippet.resourceid.videoid这个答案教会了我如何使用javascript从YouTube播放列表中获取所有视频id：

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)
