以下 Apps Script 程式碼範例適用於 YouTube Data API。您可以從 GitHub 上的 YouTube API 程式碼範例存放區的 apps-script 資料夾下載這些程式碼範例。
擷取上傳內容
這個函式會擷取目前指令碼使用者上傳的影片。執行這項操作需要 YouTube 的 OAuth 讀取/寫入範圍，以及使用者授權。在 Apps Script 的執行階段環境中，使用者第一次執行指令碼時，Apps Script 會提示使用者授予權限，以便存取指令碼所呼叫的服務。授予權限後，系統會將權限快取一段時間。當所需權限發生變更，或遭ScriptApp.invalidateAuth() 函式判定為無效時，執行指令碼的使用者將會再次收到權限提示。這段指令碼會採取下列步驟，擷取活躍使用者上傳的影片：
- 擷取使用者的頻道。
- 擷取使用者的「上傳」播放清單。
- 逐一檢查這個播放清單，並記錄影片 ID 和標題。
- 擷取下一頁憑證 (如果有的話)。如果有下一頁，則擷取該頁面。重複步驟 3。
/** * This function retrieves the current script user's uploaded videos. To execute, * it requires the OAuth read/write scope for YouTube as well as user authorization. * In Apps Script's runtime environment, the first time a user runs a script, Apps * Script will prompt the user for permission to access the services called by the * script. After permissions are granted, they are cached for some periodF of time. * The user running the script will be prompted for permission again once the * permissions required change, or when they are invalidated by the * ScriptApp.invalidateAuth() function. * * This script takes the following steps to retrieve the active user's uploaded videos: * 1. Fetches the user's channels * 2. Fetches the user's 'uploads' playlist * 3. Iterates through this playlist and logs the video IDs and titles * 4. Fetches a next page token (if any). If there is one, fetches the next page. GOTO Step 3 */ function retrieveMyUploads() { var results = YouTube.Channels.list('contentDetails', {mine: true}); for(var i in results.items) { var item = results.items[i]; // Get the playlist ID, which is nested in contentDetails, as described in the // Channel resource: https://developers.google.com/youtube/v3/docs/channels var playlistId = item.contentDetails.relatedPlaylists.uploads; var nextPageToken = ''; // This loop retrieves a set of playlist items and checks the nextPageToken in the // response to determine whether the list contains additional items. It repeats that process // until it has retrieved all of the items in the list. while (nextPageToken != null) { var playlistResponse = YouTube.PlaylistItems.list('snippet', { playlistId: playlistId, maxResults: 25, pageToken: nextPageToken }); for (var j = 0; j < playlistResponse.items.length; j++) { var playlistItem = playlistResponse.items[j]; Logger.log('[%s] Title: %s', playlistItem.snippet.resourceId.videoId, playlistItem.snippet.title); } nextPageToken = playlistResponse.nextPageToken; } } }
依關鍵字搜尋
這個函式會搜尋與關鍵字'dogs' 相關的影片。搜尋結果的影片 ID 和標題會記錄到 Apps Script 的記錄中。請注意，這個範例會將結果限制在 25 個。如要傳回更多結果，請按照「Search:list」一文所述，傳遞其他參數。
/** * This function searches for videos related to the keyword 'dogs'. The video IDs and titles * of the search results are logged to Apps Script's log. * * Note that this sample limits the results to 25. To return more results, pass * additional parameters as documented here: * https://developers.google.com/youtube/v3/docs/search/list */ function searchByKeyword() { var results = YouTube.Search.list('id,snippet', {q: 'dogs', maxResults: 25}); for(var i in results.items) { var item = results.items[i]; Logger.log('[%s] Title: %s', item.id.videoId, item.snippet.title); } }
依主題搜尋
這個函式會搜尋與特定 Freebase 主題相關聯的影片，並將影片 ID 和標題記錄到 Apps Script 記錄檔。本範例使用 Google Apps Script 的專題 ID。請注意，這個範例會將結果限制在 25 個。如要傳回更多結果，請按照「Search:list」一文所述，傳遞其他參數。
/** * This function searches for videos that are associated with a particular Freebase * topic, logging their video IDs and titles to the Apps Script log. This example uses * the topic ID for Google Apps Script. * * Note that this sample limits the results to 25. To return more results, pass * additional parameters as documented here: * https://developers.google.com/youtube/v3/docs/search/list */ function searchByTopic() { var mid = '/m/0gjf126'; var results = YouTube.Search.list('id,snippet', {topicId: mid, maxResults: 25}); for(var i in results.items) { var item = results.items[i]; Logger.log('[%s] Title: %s', item.id.videoId, item.snippet.title); } }
訂閱頻道
這個範例會將活躍使用者訂閱由 channelId 指定的 Google Developers YouTube 頻道。/** * This sample subscribes the active user to the Google Developers * YouTube channel, specified by the channelId. */ function addSubscription() { // Replace this channel ID with the channel ID you want to subscribe to var channelId = 'UC_x5XG1OV2P6uZZ5FSM9Ttw'; var resource = { snippet: { resourceId: { kind: 'youtube#channel', channelId: channelId } } }; try { var response = YouTube.Subscriptions.insert(resource, 'snippet'); Logger.log(response); } catch (e) { if(e.message.match('subscriptionDuplicate')) { Logger.log('Cannot subscribe; already subscribed to channel: ' + channelId); } else { Logger.log('Error adding subscription: ' + e.message); } } }
更新影片
這個範例會找出使用中的上傳內容，然後附加字串來更新最近一次上傳內容的說明。/** * This sample finds the active user's uploads, then updates the most recent * upload's description by appending a string. */ function updateVideo() { // 1. Fetch all the channels owned by active user var myChannels = YouTube.Channels.list('contentDetails', {mine: true}); // 2. Iterate through the channels and get the uploads playlist ID for (var i = 0; i < myChannels.items.length; i++) { var item = myChannels.items[i]; var uploadsPlaylistId = item.contentDetails.relatedPlaylists.uploads; var playlistResponse = YouTube.PlaylistItems.list('snippet', { playlistId: uploadsPlaylistId, maxResults: 1 }); // Get the videoID of the first video in the list var video = playlistResponse.items[0]; var originalDescription = video.snippet.description; var updatedDescription = originalDescription + ' Description updated via Google Apps Script'; video.snippet.description = updatedDescription; var resource = { snippet: { title: video.snippet.title, description: updatedDescription, categoryId: '22' }, id: video.snippet.resourceId.videoId }; YouTube.Videos.update(resource, 'id,snippet'); } }
