如何从YouTube播放列表中获取视频ID?

node.js

“ googleapis”:“ ^ 16.1.0”

我有一个播放列表,其中有两个视频。如何获得视频ID?

我尝试了这个:

// Node.js
const google = require('googleapis');
const youtube = google.youtube('v3');
const secrets = require('./secrets.json');

const results = youtube.playlists.list({
  auth: secrets.web.api_key,
  part: 'id',
  id: 'PLvxLmGsmqdZc-GYVeLhS0N_6jfrzEleQm'
});

console.log(results);

执行代码后,我收到以下消息:https

//gist.github.com/SergeyBondarenko/ea6a2aad546ded32e4a9b3cf53228fef

而且只有播放列表ID:

// Node.js
> results.responseContent.body.items
[ { kind: 'youtube#playlist',
    etag: '"gMxXHe-zinKdE9lTnzKu8vjcmDI/cYPhPXIoWu4acW3Qux1D5WZ3WwE"',
    id: 'PLvxLmGsmqdZc-GYVeLhS0N_6jfrzEleQm' } ]

itemsresults对象内部没有属性:

// Node.js
> request.i
request.isPrototypeOf  
request.init

据我了解,该items属性必须包含结果,如以下示例所示:

 // Python
 results = youtube.playlists().list(
    part="snippet,localizations",
    id=playlist_id
  ).execute()

  playlist = results["items"][0]

我使用了错误的方法来检索播放列表视频ID。使用的方法是playlistItems

// Node.js
const { google } = require('googleapis');
const youtube = google.youtube('v3');
const secrets = require('./secrets.json');

youtube.playlistItems.list({
  key: secrets.web.api_key,
  part: 'id,snippet',
  playlistId: 'PLvxLmGsmqdZc-GYVeLhS0N_6jfrzEleQm',
  maxResult: 10,
}, (err, results) => {
  console.log(err ? err.message : results.items[0].snippet);
});

结果:
