如何从 Google Drive 复制文件夹以使用 JS 在 Google Drive 中创建新文件夹

Question

我想将文件夹复制到 Google Drive 中的主文件夹中。 我的主要问题是创建 function 当一列不为空白而另一列为空白时。 一旦创建了一个新文件夹，它必须粘贴到其中一列的文件夹 URL 中。

这是我到目前为止所拥有的：

function addData(){
  var activeSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Data");
  var lr = activeSheet.getLastRow();
  var lc = activeSheet.getLastColumn();
  var sourceData = sourceSheet.getRange(1, 1, lr, lc).getValues();
  for (row in sourceData) {
    if (sourceData[row][0] !== "" && sourceData[row][19] !== "") {
      var rowNum = parseInt(row);

     //code will go here for Folder copying and renaming and getting the new folder url

     activeSheet.getRange(rowNum+1,lc).setValue("Completed"); //we will eventually change Completed with the new Folder URL
  }
 }
}

主要思想是使用 Folder.getFiles() 迭代文件和使用Folder.getFiles() Folder.getFolders()文件夹。 使用Folder.createFolder(name)新文件夹并使用File.makeCopy(name, destination)复制文件：

/**
 * Copies all the files in a folder to another one.
 */
function copyFolderContents_(source, target) {
  // Iterate files in source folder
  const filesIterator = source.getFiles()
  while (filesIterator.hasNext()) {
    const file = filesIterator.next()

    // Make a copy of the file keeping the same name
    file.makeCopy(file.getName(), target)
  }
}

/**
 * Recursivelly copies a folder and all its subfolders with all the files
 */
function copyFolder_(toCopy, copyInto) {
  // Makes the new folder (with the same name) into the `copyInto`
  const newFolder = copyInto.createFolder(toCopy.getName())

  // Copy the contents
  copyFolderContents_(toCopy, newFolder)

  // Iterate any subfolder
  const foldersIterator = toCopy.getFolders()
  while (foldersIterator.hasNext()) {
    const folder = foldersIterator.next()

    // Copy the folder and it's contents (recursive call)
    copyFolder_(folder, newFolder)
  }
}

/**
 * Entry point to execute with the Google Apps Script UI
 */
function copyFolder() {
  // Get the folders (by ID in this case)
  const toCopy = DriveApp.getFolderById('')
  const copyInto = DriveApp.getFolderById('')

  // Call the function that copies the folder
  copyFolder_(toCopy, copyInto)
}

您需要在copyFolder()上添加要复制的文件夹的 ID 和要从中复制的文件夹。

foldersIterator和filesIterator是 Google Apps 脚本迭代器。 他们有一个方法hasNext()如果有另一个项目则返回，还有一个next()可以检索它。

请注意， copyFolder_(toCopy, copyInto)使用自身来复制其子文件夹。

• Folder.createFolder(name)（Google Apps 脚本参考）
• File.makeCopy(name, destination)（Google Apps 脚本参考）
• 迭代器（Google Ads 脚本概念）（与 Google Apps 脚本相同的实现）

此解决方案是一种检查文件或文件夹是否已被复制的变体。

如果您必须重新开始执行，这很有用。

它使用includes来检查文件/文件夹是否已被复制：

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes

它只有一层深，因此不会复制子文件夹的子文件夹。

我使用Intl.Collator添加了一个排序，因为它可以帮助我阅读控制台 output。 sort和console都不需要，但可能有用。 参考：
