如何從 Google Drive 復制文件夾以使用 JS 在 Google Drive 中創建新文件夾

Question

我想將文件夾復制到 Google Drive 中的主文件夾中。 我的主要問題是創建 function 當一列不為空白而另一列為空白時。 一旦創建了一個新文件夾，它必須粘貼到其中一列的文件夾 URL 中。

這是我到目前為止所擁有的：

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()文件夾。 使用Folder.createFolder(name)新文件夾並使用File.makeCopy(name, destination)復制文件：

/**
 * 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()上添加要復制的文件夾的 ID 和要從中復制的文件夾。

foldersIterator和filesIterator是 Google Apps 腳本迭代器。 他們有一個方法hasNext()如果有另一個項目則返回，還有一個next()可以檢索它。

請注意， copyFolder_(toCopy, copyInto)使用自身來復制其子文件夾。

參考

• Folder.getFiles()（Google Apps 腳本參考）
• Folder.getFolders()（Google Apps 腳本參考）
• Folder.createFolder(name)（Google Apps 腳本參考）
• File.makeCopy(name, destination)（Google Apps 腳本參考）
• 迭代器（Google Ads 腳本概念）（與 Google Apps 腳本相同的實現）

此解決方案是一種檢查文件或文件夾是否已被復制的變體。

如果您必須重新開始執行，這很有用。

它使用includes來檢查文件/文件夾是否已被復制：

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

它只有一層深，因此不會復制子文件夾的子文件夾。

我使用Intl.Collator添加了一個排序，因為它可以幫助我閱讀控制台 output。 sort和console都不需要，但可能有用。 參考：
