javascript - 如何在保持目录结构的情况下将文件夹上传到 Google 云端硬盘?

我正在尝试通过使用 javascript drive api 将文件夹上传到 google drive 并保持其目录结构。我实现了上传所有文件而不是文件夹中的文件夹。我还实现了通过 drive api 将一个空文件夹上传到 google drive。但是我找不到解释上传文件夹并保持其所有目录结构的资源。例如我有一个这样的文件夹:(我添加了一个链接来显示我的示例文件夹。由于我的声誉低,我无法添加直接图像。) http://postimg.org/image/h52bvb71v/

但是当我选择文件夹时,我只能上传 .txt 文件。至少 google drive api Javascript Quickstart 为我提供了该代码。我不想破坏文件夹的结构,我想将其上传到具有原始结构的驱动器。你知道我怎样才能用谷歌驱动器 api 和 javascript 做到这一点吗?谢谢。

这是我的代码。它只上传文件夹内的文件,而不上传文件夹。

最佳答案

该 api 不支持您想要的。然而,正如您发现的那样,您可以创建空文件夹。然后递归地创建所需的文件夹并将文件上传到它。
