在 Google Apps Script 中，如何获取所有子文件夹和所有子子文件夹以及所有子子子文件夹等? [英] In Google Apps Script, how would I get all subfolders and all subsubfolders and all subsubsub folders etc.?

问题描述

我试图重命名指定文件夹中的每个文件以及所有子文件夹中的所有文件，但我不知道如何这样做.到目前为止，我已经有了这个脚本，可以根据 ID 重命名文件夹中的每个文件，但我需要对所有子文件夹进行重命名.

I am attempting to rename every file in a specified folder and all files in all subfolders but I cannot figure out how to do so. I so far have this script that renames every file in a folder given its Id, but I need to do all subfolders.

function renameFilesInFolder(folderID) {
  var folder = DriveApp.getFolderById(folderID)
  var files = folder.getFiles(),
      fileNames = []
  

  while(files.hasNext()){
    var file = files.next()
    var oldFileName = file.getName()
    var checkIfMatch = oldFileName.substring(oldFileName.length - 3);
    var newFileName = ""
    if (checkIfMatch=="OBS"){
      newFileName = oldFileName
    } else {
      newFileName =oldFileName+"_OBS"
    }
    file.setName(newFileName)
    Logger.log(newFileName)
  }
}

谢谢！

推荐答案

这将遍历文件夹，将它们写入电子表格.

This will recurse through the folder writing them into a spreadsheet.

var level=0;
function getFnF(folder) {
  var folder= folder || DriveApp.getRootFolder();
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('FilesAndFolders')
  var files=folder.getFiles();
  while(files.hasNext()) {
    var file=files.next();
    var firg=sh.getRange(sh.getLastRow() + 1,level + 1);
    firg.setValue(Utilities.formatString('File: %s', file.getName()));
  }
  var subfolders=folder.getFolders() 
  while(subfolders.hasNext()) {
    var subfolder=subfolders.next();
    var forg=sh.getRange(sh.getLastRow() + 1,level + 1);
    forg.setValue(Utilities.formatString('Fldr: %s', subfolder.getName()));
    level++;
    getFnF(subfolder);
  }
  level--;
}

这样做会更快一些

function getFnF1(folder = DriveApp.getRootFolder()) {
  let tree = JSON.parse(PropertiesService.getScriptProperties().getProperty('FnF'));
  //Logger.log(JSON.stringify(tree));
  if (tree.level < level) {
    tree.level = level;
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  const files = folder.getFiles();
  let row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = folder.getName(); } else { x = ''; } return x; }));
  tree.txt.push(row);
  row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = 'bold'; } else { x = 'normal'; } return x; }));
  tree.fwt.push(row);
  PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  if (files.hasNext()) {
    let row = Array.from([...Array(level).keys()], ((x, i) => { if (i == level - 1) { x = 'Files:'; } else { x = ''; } return x; }));
    tree.txt.push(row);
    tree.fwt.push(['normal']);
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  while (files.hasNext()) {
    let file = files.next();
    let row = Array.from([...Array(level + 1).keys()], ((x, i) => { if (i == level) { x = file.getName(); } else { x = ''; } return x; }));
    tree.txt.push(row);
    tree.fwt.push(['normal']);
    PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify(tree));
  }
  const subfolders = folder.getFolders()
  while (subfolders.hasNext()) {
    let subfolder = subfolders.next();
    level++;
    getFnF1(subfolder);
  }
  level--;
}

function getFilesAndFolders1() {
  const fldr = DriveApp.getFolderById(gobj.globals.projectsfolderid);
  const ss = SpreadsheetApp.getActive();
  ss.toast("Entry");
  const sh = ss.getSheetByName('Sheet1');
  sh.clearContents();
  SpreadsheetApp.flush();
  PropertiesService.getScriptProperties().setProperty('FnF', JSON.stringify({ txt: [], fwt: [], level: 0 }));
  getFnF1(fldr);
  //Logger.log(PropertiesService.getScriptProperties().getProperty('FnF'));
  let tree = JSON.parse(PropertiesService.getScriptProperties().getProperty('FnF'));
  const l = tree.level + 1
  tree.txt.forEach(r => {
    if (r.length < l) {
      //Array.from(Array(l - r.length).keys()).forEach(e => r.push(''));
      r.splice(r.length,0,...Array(l-r.length).fill(''));
    }
  });
  tree.fwt.forEach(r => {
    if (r.length < l) {
      //Array.from(Array(l - r.length).keys()).forEach(e => r.push('normal'));
      r.splice(r.length,0,...Array(l-r.length).fill('normal'));
    }
  });
  //Logger.log(JSON.stringify(tree));
  sh.getRange(1, 1, tree.txt.length, tree.level + 1).setValues(tree.txt);
  sh.getRange(1, 1, tree.fwt.length, tree.level + 1).setFontWeights(tree.fwt);
  PropertiesService.getScriptProperties().deleteProperty('FnF');
  ss.toast("EOF");
}
