Automate Google Drive SDK Authorization

[Pratik Mehta]

Guys,

I am stuck with a problem.

    #!/usr/bin/python
    
    import httplib2
    import pprint
    
    from apiclient.discovery import build
    from apiclient.http import MediaFileUpload
    from oauth2client.client import OAuth2WebServerFlow
    
    
    # Copy your credentials from the console
    CLIENT_ID = 'YOUR_CLIENT_ID'
    CLIENT_SECRET = 'YOUR_CLIENT_SECRET'
    
    # Check https://developers.google.com/drive/scopes for all available scopes
    OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'
    
    # Redirect URI for installed apps
    REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob'
    
    # Path to the file to upload
    FILENAME = 'document.txt'
    
    # Run through the OAuth flow and retrieve credentials
    flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI)
    authorize_url = flow.step1_get_authorize_url()
    print 'Go to the following link in your browser: ' + authorize_url
    code = raw_input('Enter verification code: ').strip()
    credentials = flow.step2_exchange(code)
    
    # Create an httplib2.Http object and authorize it with our credentials
    http = httplib2.Http()
    http = credentials.authorize(http)
    
    drive_service = build('drive', 'v2', http=http)
    
    # Insert a file
    media_body = MediaFileUpload(FILENAME, mimetype='text/plain', resumable=True)
    body = {
      'title': 'My document',
      'description': 'A test document',
      'mimeType': 'text/plain'
    }
    
    file = drive_service.files().insert(body=body, media_body=media_body).execute()
    pprint.pprint(file)


The above code asks user to copy the url to the browser, and then authorize their account, and then again, copy-paste the code and paste it on the terminal. I know storing the credentials and using the refresh tokens, users will have to do this just for once.

But, I don't want so much of user-interactions. Is it possible that user authorizes by just logging in to their gmail account? As in, from my code itself, the authorization link should get open in a web browser without user doing it, and just signs in to his/her account, and that's it, authorization is done, and this login should also happen for just one time, as in, one time authorization, so that whatever is uploaded, gets uploaded on his Google Drive account and maintained. The authorization code should be directly retrieved, and these credentials should be stored as usual and be used and tokens should also be refreshed.

I came across Google Drive Service Account, good thing is that user-intervention is gone completely, but bad thing is that, it doesn't allow the account where the file is to be uploaded. It uploads the file on that drive who has created the app.

Can anyone pls help me out with this? If going with the above code, then what should I be doing to automate the task? If going with the Service Account, what should I be doing to make the app upload the data to the user's own drive account?

Any help would be appreciated.

Thanks!
