Google 应用程序脚本 - 迭代文件夹和子文件夹 [英] Google apps script - iterate folder and subfolder

问题描述

我想使用 google apps 脚本遍历 Google Drive 中文件夹的树结构.下面的代码列出了一些文件夹，但不是全部.你能建议什么是深入文件夹结构的最佳技术吗?我首先尝试记录所有文件夹名称.

I want to iterate through the tree structure of the folder in Google Drive using google apps script. The code below is listing some of the folders but not all. Can you advice what is best technique for drill down the folders structure? I am trying to log all folder names at first.

谢谢.

function test() {
 listSubfolders(DriveApp.getFolderById('FOLDER_ID'));
}

function listSubfolders(parentFolder) {
  var childFolders = parentFolder.getFolders();

 while(childFolders.hasNext()) {
   Logger.log(childFolders.next().getName());
   listSubfolders(childFolders.next());   

 }


}

推荐答案

要访问子文件夹，可以这样做，

To access the sub folders, you can do in this way,

function getSubFolders(parent) {
  parent = parent.getId();
  var childFolder = DriveApp.getFolderById(parent).getFolders();
  while(childFolder.hasNext()) {
    var child = childFolder.next();
    Logger.log(child.getName());
    getSubFolders(child);
  }
  return;
}

function listFolders() {
  var parentFolder = DriveApp.getFolderById("0B1n6YLYwFmK_dUpzRWhDRXNwdWc");
  var childFolders = parentFolder.getFolders();
  while(childFolders.hasNext()) {
    var child = childFolders.next();
    Logger.log(child.getName());
    getSubFolders(child);
  }
}
