Google Drive Refresh Access Token

See more Google Drive Examples

Demonstrates how to automatically refresh the access token when it expires. Ruby

require 'chilkat'

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"
# }

    exit

# Save the new access token to our JSON file (so we can refresh it again when needed).
