我已经使用Corona SDK在lua中编写了一个应用程序，我正在尝试从谷歌驱动器文件夹下载一些图像。
我已经使用OAth游乐场对我需要的作用域进行了身份验证，我已经获得了一个刷新令牌，并在必要时获得了一种新的访问令牌的方法。这就是我下载图像的方式：
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是指获得的json，它列出了指定文件夹中的所有文件。这在几天前运行良好，但现在每当我尝试它时，下载的图像都是无效和损坏的。我甚至尝试在驱动器中使用一个新文件夹。
我试过其他链接，比如
https://www.googleapis.com/drive/v3/files/FILE_ID_HERE?alt=media
还有一些我在网上看到的，但这些给了我
code 403
"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
错误。我在某个地方读到指定作用域可以修复代码403错误，但我不确定具体在哪里指定。
我很感激你的帮助，谢谢！
编辑：我用文本编辑器看了一张图片，结果是一些html，看起来像是谷歌认证页面的代码，其中一些如下：

我不能发布整个东西，因为它超过了身体特征限制
我使用了一个不同的url并添加了以下内容：
local params = {}
params.progress = true
params.headers = headers
