php – Google云端硬盘服务帐户和“未经授权的客户端或请求范围

1,作品,2不.

返回的错误是“刷新OAuth2令牌时出错,消息：'{”错误“：”unauthorized_client“,”error_description“：”请求中未经授权的客户端或范围.“}’”

所有3个帐户都在开发者控制台中注册.
所有3个都有权在Google Apps控制台中进行“托管客户端API访问”.
所有3的范围都是“https://www.googleapis.com/auth/drive.readonly”.
所有3个驱动器,都有一个特定的文件夹,共享为“仅查看”.

我正在使用PHP并将一个参数传递给名为“type”的页面,并反映了该帐户的用途,1表示公共,1表示成员,1表示管理员.

例如

http://www.somehost.com/oauth_client.php?type=googledrive_admin

p12证书和用户值存储在服务器上.所有“ini”文件都具有相同的值结构,client_id,client_email,范围和查询过滤器.在所有情况下,文件之间唯一更改的项是client_id和client_email.

我的代码如下：

<?php

 include (__DIR__ . "/google-api-php-client/autoload.php");

 google_api_php_client_autoload("Google_Auth_AssertionCredentials");
 google_api_php_client_autoload("Google_Client");
 google_api_php_client_autoload("Google_Service_Drive");
 google_api_php_client_autoload("Google_Service_OAuth2");

 $type = $_GET['type'];
 $path = __DIR__ . "/secure/";
 $certificate = $path . $type . ".p12";
 $ini_path = $path . $type . ".ini";

 $ini = parse_ini_file($ini_path);
 $service_scope = $ini['scope'];
 $service_account_id = $ini['id'];
 $service_account_email = $ini['email'];
 $service_query = $ini['q'];

 $service_account_key = file_get_contents($certificate);
 $credentials = new Google_Auth_AssertionCredentials(
  $service_account_email,array($service_scope),$service_account_key
 );
 $credentials -> sub = $service_account_email;

 $google_client = new Google_Client();

 $google_client -> setAssertionCredentials($credentials);
 if ($google_client -> getAuth() -> isAccessTokenExpired()) {
  $google_client -> getAuth() -> refreshTokenWithAssertion(); **//FAILS HERE**
 }  

 $drive = new Google_Service_Drive($google_client);

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

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

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

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

 echo json_encode($result) . "n";
?>

每个ini文件的结构如下

id="35{code}.apps.googleusercontent.com"
email="35{code}@developer.gserviceaccount.com"
scope="https://www.googleapis.com/auth/drive.readonly"
q="mimeType != 'application/vnd.google-apps.folder'"

我无法解决的问题是,当我为所有这些帐户完成相同的过程时,为什么这适用于一个服务帐户而不适用于其他服务帐户.任何想法和帮助表示赞赏.
