YouTube 服務

透過 YouTube 服務，您可以在 Apps Script 中使用 YouTube Data API 和 YouTube Live Streaming API。這個 API 可讓使用者管理自己的影片、播放清單、頻道及現場直播。

如要進一步瞭解這項服務，請參閱下列參考說明文件：

如同 Apps Script 的所有進階服務，YouTube 服務會使用與公用 API 相同的物件、方法和參數。詳情請參閱「如何判定方法簽章」一文。

程式碼範例

下方程式碼範例使用第 3 版的 YouTube Data API。

依關鍵字搜尋

這個函式會搜尋犬隻相關影片，並記錄影片 ID 和標題。請注意，這個樣本會將結果限制為 25 個結果。若要傳回更多結果，請傳送 YouTube Data API 參考說明文件中顯示的其他參數。

advanced/youtube.gs
/**
 * Searches for videos about dogs, then logs the video IDs and title.
 * Note that this sample limits the results to 25. To return more
 * results, pass additional parameters as shown in the YouTube Data API docs.
 * @see https://developers.google.com/youtube/v3/docs/search/list
 */
function searchByKeyword() {
  try {
    const results = YouTube.Search.list('id,snippet', {
      q: 'dogs',
      maxResults: 25
    });
    if (results === null) {
      console.log('Unable to search videos');
      return;
    }
    results.items.forEach((item)=> {
      console.log('[%s] Title: %s', item.id.videoId, item.snippet.title);
    });
  } catch (err) {
    // TODO (developer) - Handle exceptions from Youtube API
    console.log('Failed with an error %s', err.message);
  }
}

擷取上傳內容

這個函式會擷取使用者上傳的影片。方法是按照下列步驟進行：

  1. 擷取使用者的頻道
  2. 擷取使用者的uploads播放清單
  3. 從此播放清單進行疊代，並記錄影片 ID 和標題
  4. 如果仍有結果頁面，請擷取結果，然後返回步驟 3。
advanced/youtube.gs
/**
 * This function retrieves the user's uploaded videos by:
 * 1. Fetching the user's channel's.
 * 2. Fetching the user's "uploads" playlist.
 * 3. Iterating through this playlist and logs the video IDs and titles.
 * 4. If there is a next page of resuts, fetching it and returns to step 3.
 */
function retrieveMyUploads() {
  try {
    // @see https://developers.google.com/youtube/v3/docs/channels/list
    const results = YouTube.Channels.list('contentDetails', {
      mine: true
    });
    if (!results || results.items.length === 0) {
      console.log('No Channels found.');
      return;
    }
    for (let i = 0; i < results.items.length; i++) {
      const item = results.items[i];
      /** Get the channel ID - it's nested in contentDetails, as described in the
       * Channel resource: https://developers.google.com/youtube/v3/docs/channels.
       */
      const playlistId = item.contentDetails.relatedPlaylists.uploads;
      let nextPageToken = null;
      do {
        // @see: https://developers.google.com/youtube/v3/docs/playlistItems/list
        const playlistResponse = YouTube.PlaylistItems.list('snippet', {
          playlistId: playlistId,
          maxResults: 25,
          pageToken: nextPageToken
        });
        if (!playlistResponse || playlistResponse.items.length === 0) {
          console.log('No Playlist found.');
          break;
        }
        for (let j = 0; j < playlistResponse.items.length; j++) {
          const playlistItem = playlistResponse.items[j];
          console.log('[%s] Title: %s',
              playlistItem.snippet.resourceId.videoId,
              playlistItem.snippet.title);
        }
        nextPageToken = playlistResponse.nextPageToken;
      } while (nextPageToken);
    }
  } catch (err) {
    // TODO (developer) - Handle exception
    console.log('Failed with err %s', err.message);
  }
}

訂閱頻道

這個範例將使用者訂閱 YouTube 上的 Google Developers 頻道。

advanced/youtube.gs
/**
 * This sample subscribes the user to the Google Developers channel on YouTube.
 * @see https://developers.google.com/youtube/v3/docs/subscriptions/insert
 */
function addSubscription() {
  // Replace this channel ID with the channel ID you want to subscribe to
  const channelId = 'UC_x5XG1OV2P6uZZ5FSM9Ttw';
  const resource = {
    snippet: {
      resourceId: {
        kind: 'youtube#channel',
        channelId: channelId
      }
    }
  };

  try {
    const response = YouTube.Subscriptions.insert(resource, 'snippet');
    console.log('Added subscription for channel title : %s', response.snippet.title);
  } catch (e) {
    if (e.message.match('subscriptionDuplicate')) {
      console.log('Cannot subscribe; already subscribed to channel: ' +
        channelId);
    } else {
      // TODO (developer) - Handle exception
      console.log('Error adding subscription: ' + e.message);
    }
  }
}
