Question

我正在编写一个应用程序来从Google云端硬盘中检索文件（在我自己的云端硬盘帐户中）。

我创建了一个Google服务帐户以避免OAuth流程，因为我使用的是自己的Google云端硬盘帐户。

然后我从Google获取了这个代码示例：

function buildService() {

$SERVICE_ACCOUNT_EMAIL = 'xxxx@developer.gserviceaccount.com'; 
$SERVICE_ACCOUNT_PKCS12_FILE_PATH = 'xxx-privatekey.p12';

  $key = file_get_contents($SERVICE_ACCOUNT_PKCS12_FILE_PATH);
  $auth = new Google_AssertionCredentials(
      $SERVICE_ACCOUNT_EMAIL,
      array('https://www.googleapis.com/auth/drive'),
      $key);
  $client = new Google_Client();
  $client->setUseObjects(true);
  $client->setAssertionCredentials($auth);

  return new Google_DriveService($client);
}



function retrieveAllFiles($service) {

  $result = array();
  $pageToken = NULL;

  do {
    try {
      $parameters = array();
      if ($pageToken) {
        $parameters['pageToken'] = $pageToken;
      }

      $files = $service->files->listFiles($parameters);


      $result = array_merge($result, $files->getItems());
      $pageToken = $files->getNextPageToken();
    } catch (Exception $e) {
      print "An error occurred: " . $e->getMessage();
      $pageToken = NULL;
    }
  } while ($pageToken);
  return $result;
}


$service = buildService();

$allFiles = retrieveAllFiles($service);

print_r($allFiles);

当我有文件和文件夹时，它会返回一个空数组：

Array

在配置中，电子邮件和私钥都可以，由Google自己提供;我做错了什么？

尝试更改代码https://developers.google.com/drive/delegation：

  function buildService($userEmail) {

   $SERVICE_ACCOUNT_EMAIL = 'xxxx@developer.gserviceaccount.com'; 
   $SERVICE_ACCOUNT_PKCS12_FILE_PATH = 'xxx-privatekey.p12';

   $key = file_get_contents($SERVICE_ACCOUNT_PKCS12_FILE_PATH);
   $auth = new Google_AssertionCredentials(
     $SERVICE_ACCOUNT_EMAIL,
     array('https://www.googleapis.com/auth/drive'),
     $key);
   $auth->sub = $userEmail;
   $client = new Google_Client();
   $client->setUseObjects(true);
   $client->setAssertionCredentials($auth);

   return new Google_DriveService($client);
 }

 //... function retrieveAllFiles($service) 

 $service = buildService("some@mail");
 $allFiles = retrieveAllFiles($service);
 print_r($allFiles);

Google Drive API（PHP）无法列出文件
