javascript - getFiles 和 getFolders 总是只返回一个文件/文件夹

Question

当尝试从我的 Google 云端硬盘接收所有文件和文件夹时，函数 .getFiles() 仅返回一个文件，而 .getFolders() 仅返回一个文件夹. 我的驱动器中确实有多个文件夹和文件。

我的代码:

function run() {
    try { 
        const folders = DriveApp.getFolders();
        const files = DriveApp.getFiles();

        while (folders.hasNext()) {
            const folder = folders.next();
            console.log(folder.getName())


            folder.setSharing(DriveApp.Access.PRIVATE, DriveApp.Permission.EDIT)
            if (folder.getSharingAccess() !== DriveApp.Access.PRIVATE)
              console.error("Permission was not changed, or changed incorrectly")
        }

        while (files.hasNext()) {
            const file = files.next();
            console.log(file.getName())
            file.setSharing(DriveApp.Access.PRIVATE, DriveApp.Permission.EDIT)
            if (file.getSharingAccess() !== DriveApp.Access.PRIVATE)
              console.error("Permission was not changed, or changed incorrectly")
        }
    } catch (err) { 
      console.error(err)
    }
}

我希望 console.log(file.getName()) 和 console.log(folder.getName()) 显示不同文件的信息，但是它总是相同的:

在这种情况下使用 const 键名进行赋值会阻止您获得所需的结果。

JavaScript const - Documentation

The value of a constant cannot change through reassignment, and it can't be redeclared

目前:

const folder = folders.next();

更改为:

var folder = folders.next();
