问题
I have created two refresh tokens for me: one for
SCOPE = 'https://www.googleapis.com/auth/drive'
and another
SCOPE = 'https://www.googleapis.com/auth/drive.file'
I'm trying to get information about files (using get method) Some files I can get when using SCOPE drive.files, and some only when using wider scope drive
But I can not figure out what is the reason for that? Files are located in different folders but have one shared root folder.
回答1:
The difference is that 'drive.file' only gives you permission to files that your app has created or the user has explicitly shared with your app, whereas 'drive' gives your app permission to see the all the files in the user's drive.
See
https://developers.google.com/drive/web/scopes

You should really look into using drive.file, that is where they are trying to push users. I was just fighting with this myself and found that if you use the drive.file scope, you can then subsequently open the file that is chosen using the API for the file type, but only if you set the correct AppID.
See here: https://developers.google.com/picker/docs/#gdata
This allows you to get past the 404 error that you get if you don't set the AppID.
