Google Drive Refresh Access Token

Demonstrates how to automatically refresh the access token when it expires. Chilkat2-Python

import sys
import chilkat2

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

success = True

# This example uses a previously obtained access token having permission for the 
# Google Drive scope.

# The access token (and refresh token) was previously saved to a JSON file with this format:
# See Get Google Drive OAuth2 Access Token

# {
#   "access_token": "ya29.Gls-BsdxTWuenChv ... yzVIrXikkLxu5T6dy4I6GjADFardoz4Lruw",
#   "expires_in": 3600,
#   "refresh_token": "1/tMBJ ... 27D-Hk6rpQYBA",
#   "scope": "https://www.googleapis.com/auth/drive",
#   "token_type": "Bearer"
# }
