Answer 1

您可以使用official YouTube API channels.list 方法获取如下统计信息：subscriberCount、videoCount 和 viewCount。

Get statistics from a YouTube channel	Run in Fusebit

const youtube = googleClient.youtube('v3');
const channelName = 'GoogleDevelopers';
const channelsResponse = await youtube.channels.list({
  part: 'id,statistics',
  forUsername: channelName,
});

if (channelsResponse.data.items && channelsResponse.data.items.length) {
  const { statistics: { subscriberCount, videoCount, viewCount } } = channelsResponse.data.items[0];
  console.log(`The channel ${channelName} has ??‍?‍?? ${subscriberCount} subscribers, ? ${videoCount} videos and ? ${viewCount} views.`);
} else {
  console.log = `Channel not found: ${channelName}`;
}

基于 cmets，这里是一个如何根据搜索词搜索频道的示例，然后您将使用频道 id 从前面的代码中获取统计信息，而不是发送 forUserName 参数您将发送 id See search API docs here

  const channelsResponse = await youtube.search.list({
    part: 'snippet',
    q: searchTerm,
    maxResults: 10,
    type: 'channel',
    order: 'viewCount' // show more popular first
  });

这是搜索中每个项目返回的response object

{
  "kind": "youtube#searchResult",
  "etag": etag,
  "id": {
    "kind": string,
    "videoId": string,
    "channelId": string,
    "playlistId": string
  },
  "snippet": {
    "publishedAt": datetime,
    "channelId": string,
    "title": string,
    "description": string,
    "thumbnails": {
      (key): {
        "url": string,
        "width": unsigned integer,
        "height": unsigned integer
      }
    },
    "channelTitle": string,
    "liveBroadcastContent": string
  }
}
