Google Apps 脚本：将文件夹添加到文件夹

Question

我使用脚本将带有图像的文件夹上传到（父？）文件夹。当我这样做时，确实会以正确的方式创建文件夹结构。但是，当我第二次尝试时，它会在根目录中创建一个同名的新文件夹。

如何更改我的代码，以便有一个将添加图像文件夹的父文件夹？

目前：

• 第一次：/root/persons/test test@test.com/（此文件夹内的图片）
• 第二次新建地图：/root/persons/test2 test2@test2.com/（此文件夹内的图片）

我想要：
/root/persons/*(folders)/（此文件夹中的图片）

我的代码：

/* The script is deployed as a web app and renders the form */
function doGet(e) {
return HtmlService.createHtmlOutputFromFile('form.html')
        .setSandboxMode(HtmlService.SandboxMode.NATIVE);
// This is important as file upload fail in IFRAME Sandbox mode.
}

/* This function will process the submitted form */
function uploadFiles(form) {

try {

/* Name of the Drive folder where the files should be saved */
var dropbox = form.myName + " " + form.myEmail;
var folder, folders = DriveApp.getFoldersByName(dropbox);

/* Find the folder, create if the folder does not exist */
if (folders.hasNext()) {
  folder = folders.next();
} else {
  var firstLevelFolder = DriveApp.createFolder("Persons");
  var folder = firstLevelFolder.createFolder(dropbox);
}

/* Get the file uploaded though the form as a blob */
var blob = form.myFile;    
var file = folder.createFile(blob);    

/* Set the file description as the name of the uploader */
file.setDescription("Uploaded by " + form.myName);

/* Return the download URL of the file once its on Google Drive */
return "File uploaded successfully " + file.getUrl();

} catch (error) {

/* If there's an error, show the error message */
return error.toString();
}

}

您没有测试“Persons”文件夹是否存在，因此每次您有一个新用户时，您都会重新创建该文件夹。我建议在函数的早期执行此操作，如下所示：

/* Find the first level folder, create if the folder does not exist */
var firstLevelFolderName = "Persons";
var folders = DriveApp.getFoldersByName(firstLevelFolderName);
var firstLevelFolder = (folders.hasNext()) ? folders.next() : DriveApp.createFolder(firstLevelFolderName);

注意使用ternary operator ? 将赋值保留在一个语句中，而不是显式的if..then..else 结构。相同的模式可用于任何正在评估“查找与创建”的迭代器。

更新脚本：

/* This function will process the submitted form */
function uploadFiles(form) {
  
  try {
    /* Find the first level folder, create if the folder does not exist */
    var firstLevelFolderName = "Persons";
    var folders = DriveApp.getFoldersByName(firstLevelFolderName);
    var firstLevelFolder = (folders.hasNext()) ? folders.next() : DriveApp.createFolder(firstLevelFolderName);
    
    /* Find the user-specific folder, create if the folder does not exist */
    var dropbox = form.myName + " " + form.myEmail;    /* Name of the Drive folder where the files should be saved */    
    folders = DriveApp.getFoldersByName(dropbox);
    var folder = (folders.hasNext()) ? folders.next() : firstLevelFolder.createFolder(dropbox); 
    
    /* Get the file uploaded though the form as a blob */
    var blob = form.myFile;    
    var file = folder.createFile(blob);    
    
    /* Set the file description as the name of the uploader */
    file.setDescription("Uploaded by " + form.myName);
    
    /* Return the download URL of the file once its on Google Drive */
    return "File uploaded successfully " + file.getUrl();
    
  } catch (error) {
    
    /* If there's an error, show the error message */
    return error.toString();
  }
  
}

这对我来说可以在现有文件夹中创建一个文件夹

const parentFolder = DriveApp.getFolderById("1TukDeifX_nYZftbzODkUfD-hYlpx5TPg");
const folder1 = parentFolder.createFolder(Project + ", " + Date + ", " + Phone);
