Google Php Api：如何以毫不含糊的方式设置Google_client对象

Question

我有一个移动应用程序，用于处理Google帐户的登录和服务身份验证，响应数据包括：access_token，id_token，refresh_token和serverauthcode。它将这些数据传递给Web服务器。

如何使用这些数据直接将它们设置为Google_Client对象，而无需重定向网址和服务身份验证，因为该作业已在移动应用上完成。谢谢！

 These are my code:

function accessService(){
  $client_obj = $this->googleAccessToken();
  $service = new Google_Service_Calendar($client_obj);
  $calendarId = 'primary';
            $optParams = array(
              'maxResults' => 10,
              'orderBy' => 'startTime',
              'singleEvents' => TRUE,
              'timeMin' => date('c'),
            );
  $results = $service->events->listEvents($calendarId, $optParams);
  print_r($results);

  //Im getting Error here in this part 
  // Uncaught exception 'Google_Service_Exception' with message '{
  //"error": "unauthorized_client",
  //"error_description": "Unauthorized"}
 }

function googleAccessToken(){
    $idtoken = 'id_token_from_app';
    $refreshtoken = 'refresh_token_from_app';
    $access_token = 'access_token_from_app';

      $credentials=array('id_token'=>$idtoken,'refresh_token'=>$refreshtoken,'access_token'=>$access_token);

$client = new Google_client();
$client->setApplicationName('CalendarApp');
$client->setAuthConfig('path_to_my_client_secret.json');
$client->setAccessToken(json_encode($credentials));

return $client;
}
