我是否需要提交以下 google 驱动器范围的验证请求才能从选择器下载文件？

Question

googleapis.com/auth/drive
www.googleapis.com/auth/drive.readonly

由于以下错误，选取器未加载

我的 objective 是从 google 驱动器下载一个文件到我们的网站。

当我使用 drive.file 时选择器加载，但是当我尝试下载文件时出现 404 文件未找到错误。

在该网站上使用 google 驱动器参考 files/get 我可以模拟 404 但如果我将范围更改为仅使用驱动器或 drive.readonly 我会得到 200 状态我在找什么，但选择器没有加载。

有没有无需提交验证申请表即可解决此问题的方法？

我使用的代码基于 google 驱动示例代码。

Answer 1

首先，我建议使用 https://www.googleapis.com/auth/drive 以获得完整范围。然后，给我们看看代码是什么，你是怎么做到的？

Answer 2

您没有在变量选择器中设置范围

      var picker = new google.picker.PickerBuilder().
          addView(view).
          addView(google.picker.ViewId.DOCS).//<== add this

我是否需要提交以下 google 驱动器范围的验证请求才能从选择器下载文件？

Do i require to Submit a verfication request for the following google drive scopes in order to download a file from picker?
