if (!isset($_GET['code'])) {
// If we don't have an authorization code then get one
$authUrl = $provider->getAuthorizationUrl();
$_SESSION['oauth2state'] = $provider->getState();

$token = $provider->getAccessToken('authorization_code', [
'code' => $_GET['code']
]);

try {
// We got an access token, let's now get the user's details
$user = $provider->getResourceOwner($token);
