YouTube 服務

您可以在 Apps Script 中使用 YouTube Data API 和 YouTube Live Streaming API。這個 API 可讓使用者管理影片、播放清單、頻道和直播活動。

與 Apps Script 中的所有進階服務一樣，YouTube 服務使用的物件、方法和參數都與公開 API 相同。詳情請參閱「如何判斷方法簽章」。

程式碼範例

下方的程式碼範例使用 YouTube Data API 的第 3 版。

依關鍵字搜尋

這個函式會搜尋有關狗狗的影片，然後記錄影片 ID 和標題。 請注意，這個範例將結果限制為 25 個。如要傳回更多結果，請傳遞其他參數，如 YouTube Data API 參考說明文件所示。

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;
    }
    for (const item of results.items) {
      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

這項函式會擷取使用者上傳的影片。這項作業會透過下列步驟完成：

  1. 擷取使用者的頻道
  2. 擷取使用者的「uploads」播放清單
  3. 逐一查看播放清單，並記錄影片 ID 和標題
  4. 如有下一頁結果，則擷取該頁面，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

這個範例會讓使用者訂閱 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}`);
    }
  }
}
