Get a refresh_token with google

You can get a refresh_token with google. Use set_access_type() method for that. But :

• The refresh_token is given the first time you asked for it

• To have a new refresh_token you have to revoke the first one before

You ask for a refresh_token in the authorization process :

<?php
require dirname(__FILE__, 2) . '/vendor/autoload.php';

$disco_url = 'https://accounts.google.com/.well-known/openid-configuration';
$client_id = 'yourClient_id';
$session_key = 'YWQ4Q1Hpb_zQliS5wGYDDPZm2xC7PzyfjgLKBNodkazkN_pEPlm7yVBw5r9_pDzSwHJRsFVZShQyb_LFUSMBGQ';
$callback_url = 'https://yourAPPurl/callback.php';

$client = new Svgta\OidcClient\init($disco_url, $client_id);
$client->setSessionKey($session_key);

$auth = $client->authorization($callback_url);

$auth->addScope('email profile');
$auth->set_access_type('offline');; // To get a refresh_token if needed and accepted by your provider
$auth->set_state();
$auth->set_nonce();

$auth->exec();
