How to have multiple scopes with Google Calendar + Google Drive

问题

I am new to the Google APIs and want to know how I would be able to access 2 different APIs within the same files.

I have

SCOPES = 'https://www.googleapis.com/auth/calendar'

but I also want

SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'

to be accessible from the same file. Does anyone have any idea how to go about doing this?

Thanks!

When you authenticate simply add both scopes. The user will be prompted to grant you access to both.

SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly https://www.googleapis.com/auth/calendar'

You may have to put a comma between them I a not sure it depends upon the library

Now I am not a python dev, however most of the Google client libraries are created the same. Assuming you are using that you will need to create both a calendar service and a drive service. You create them both using the same credential you got from above. Code ripped from here.

serviceDrive = discovery.build('drive', 'v3', http=http)
serviceCal = discovery.build('calendar', 'v3', http=http)

When you need to access calendar you use the calendar service when you need to access drive you use the drive service.

Add scopes into a list object.

Example:

SCOPES = ['https://www.googleapis.com/auth/calendar',
          'https://www.googleapis.com/auth/drive.metadata.readonly']
