Demonstrates how to get a Google Drive API access token using a .p12 private key. Lua

local chilkat = require("chilkat")

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

local gAuth = chilkat.AuthGoogle.new()

    return
end

if not success then
    print(gAuth.last_error_text)
    return
end

-- Choose a scope.
gAuth.scope = "https://www.googleapis.com/auth/drive"

-- Request an access token that is valid for this many seconds.
gAuth.expire_num_seconds = 3600

-- If the application is requesting delegated access:
-- The email address of the user for which the application is requesting delegated access,
-- then set the email address here. (Otherwise leave it empty.)

-- Connect to www.googleapis.com using TLS (TLS 1.2 is the default.)
-- The Chilkat socket object is used so that the connection can be established
-- through proxies or an SSH tunnel if desired.
