oauth2client is deprecated, can we use its replacement, google-auth?

Environment info

Operating System: osx Python version: 3.6 gspread version: latest

Steps to reproduce

Oauth2client documentation says it’s deprecated and we should be using google-auth

If you try to establish credentials with

credentials = service_account.Credentials.from_service_account_file(
    'service-account.json')

gc = gspread.authorize(credentials)

You’ll get this error:

Traceback (most recent call last):
  File "spreadsheet.py", line 19, in <module>
    gc = gspread.authorize(credentials)
  File "/usr/local/lib/python3.6/site-packages/gspread/client.py", line 402, in authorize
    client.login()
  File "/usr/local/lib/python3.6/site-packages/gspread/client.py", line 56, in login
    if not self.auth.access_token or \
AttributeError: 'Credentials' object has no attribute 'access_token'

Obviously, the google creditials json file doesn’t have an ‘access_token’ key, so something is amiss there.

If I instead use the deprecated

scope = ['https://spreadsheets.google.com/feeds']
credentials = ServiceAccountCredentials.from_json_keyfile_name('service-account.json', scope)
gc = gspread.authorize(credentials)

It works fine.

if you want to integrate with google_auth, I suggest you to do with the session provided by google_auth:

from google.auth.transport.requests import AuthorizedSession
gc = gspread.Client(auth=credentials)
gc.session = AuthorizedSession(credentials)
sheet = gc.open_by_key(spreadsheetId)
print sheet.title

refer to https://google-auth.readthedocs.io/en/latest/user-guide.html and this should work the same as before. just notice that session is from Requests and not httplib2.
