Google Drive API：正在下载无效图片

我已经使用Corona SDK在lua中编写了一个应用程序，我试图从google驱动器文件夹中下载一些图像。

我已经使用OAth游乐场来验证我需要的范围，并且我已经获得了刷新令牌，并且有必要获取新访问令牌的方法。这就是我下载图片的方式：

network.download(
                   "https://drive.google.com/uc?export=download&id="..decodedResponse.files[index].id,
                    "GET",
                    networkListener,
                    params,
                    decodedResponse.files[index].name,
                    system.DocumentsDirectory
                )

其中decodedResponse是指获取的json，列出指定文件夹中的所有文件。这几天前工作正常，但现在每当我尝试时，下载的图像都是无效的并且已损坏。我甚至尝试在驱动器中使用新文件夹。

我尝试了其他类似的链接，例如

https://www.googleapis.com/drive/v3/files/FILE_ID_HERE?alt=media

以及我在网上看过的其他一些人，但这些给了我一个

code 403 "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."

错误。我在某处读到指定范围可能会修复代码403错误，但我不确定在何处准确指定此内容。

我很感激帮助，谢谢！

编辑：我用文本编辑器查看了其中一个图像，结果是一些html看起来是google auth页面的代码，其中一些在下面：

我能够通过使用不同的网址并添加它来使其工作：

local params = {}
params.progress = true
params.headers = headers

这是我使用的网址： https://www.googleapis.com/drive/v3/files/FILE_ID_HERE?alt=media
