如何優化我的腳本以應對Google Apps Script的6分鐘時間限制？

Question

作為一個初學者，我編寫了一個腳本，將所有我的Google Drive資料夾填入Google表格中。即使腳本可以工作，但我遇到了錯誤：超過最大執行時間，而我的資料夾結果清單還沒有完成。

我無法弄清楚如何處理/修復執行逾時。我已經搜尋了多個來源，但沒有找到可以幫助我加快腳本速度的東西。

我的期望是腳本將超快地執行，並且「可能」的數千個資料夾清單將在最多1分鐘內填充。

GAS腳本

function generateFolderList() {
  var rootFolder = DriveApp.getRootFolder();
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheetName = Utilities.formatDate(new Date(), "GMT+1", "yyyy-MM-dd HH:mm:ss");
  var newSheet = spreadsheet.insertSheet(sheetName);
  newSheet.getRange("A1:N1").setValues([["structure_level", "parent_folder", "folder_name", "folder_description", "folder_id", "folder_url", "owner_email", "sharing_access", "sharing_permissions", "mime_type", "starred_status", "trashed_status", "date_created", "last_updated"]]);
  listFolders(rootFolder, "", newSheet, 1);
}

function listFolders(folder, parentName, sheet, level) {
  var folderName = folder.getName();
  var description = folder.getDescription();
  var folderId = folder.getId();
  var url = folder.getUrl();
  var owner = folder.getOwner().getEmail();
  var sharingAccess = folder.getSharingAccess();
  var sharingPermission = folder.getSharingPermission();
  var mimeType = "folder";
  var starred = folder.isStarred();
  var trashed = folder.isTrashed();
  var dateCreated = folder.getDateCreated();
  var lastUpdated = folder.getLastUpdated();
  
  var rowData = [level, parentName, folderName, description, folderId, url, owner, sharingAccess, sharingPermission, mimeType, starred, trashed, dateCreated, lastUpdated];
  sheet.appendRow(rowData);
  
  var subFolders = folder.getFolders();
  level++;
  while (subFolders.hasNext()) {
    var subFolder = subFolders.next();
    listFolders(subFolder, folderName, sheet, level);
  }
}

包含Apps腳本的Google表格在此。

您的應用程式腳本會在每個資料夾或子資料夾出現時寫入電子表格。相反，您應該將資訊收集到一個陣列中，然後將整個陣列寫入電子表格。嘗試這樣做，儘管一開始有些單元格的值是物件而不是字串，所以在決定要捕獲這些物件的哪個屬性之前，它不會起作用。我只是使用了toString()。

function generateFolderList() {
  var rootFolder = DriveApp.getRootFolder();
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheetName = Utilities.formatDate(new Date(), "GMT+1", "yyyy-MM-dd HH:mm:ss");
  var newSheet = spreadsheet.insertSheet(sheetName);
  // 注意我创建了一个名为folders的数组，并将其传递给listFolders，而不是newSheet
  let folders = [["structure_level", "parent_folder", "folder_name", "folder_description", "folder_id", "folder_url", "owner_email", "sharing_access", "sharing_permissions", "mime_type", "starred_status", "trashed_status", "date_created", "last_updated"]];
  listFolders(rootFolder, "", folders, 1);
  // 完成后复制到电子表格
  newSheet.getRange(1,1,folders.length,folders[0].length.setValues(folders);
}

function listFolders(folder, parentName, folders, level) {
  var folderName = folder.getName();
  var description = folder.getDescription();
  var folderId = folder.getId();
  var url = folder.getUrl();
  var owner = folder.getOwner().getEmail();
  var sharingAccess = folder.getSharingAccess().toString();
  var sharingPermission = folder.getSharingPermission().toString();
  var mimeType = "folder";
  var starred = folder.isStarred();
  var trashed = folder.isTrashed();
  var dateCreated = folder.getDateCreated();
  var lastUpdated = folder.getLastUpdated();
  
  folders.push([level, parentName, folderName, description, folderId, url, owner, sharingAccess, sharingPermission, mimeType, starred, trashed, dateCreated, lastUpdated]);
  
  var subFolders = folder.getFolders();
  level++;
  while (subFolders.hasNext()) {
    var subFolder = subFolders.next();
    listFolders(subFolder, folderName, folders, level);
  }
}
