Google Directory API 和 PHP：请求中的未经授权的客户端或范围

Question

我正在使用 Google Directory API、oauth2 的服务帐户和 PHP，从命令行运行。

作为第一步，我只是尝试检索单个用户对象。代码如下：

require_once realpath(__DIR__ . '/../vendor/autoload.php');
session_start();
define('APPLICATION_NAME', 'Directory API PHP Quickstart');
define('SCOPES', implode(' ', 
array(Google_Service_Directory::ADMIN_DIRECTORY_USER_READONLY)));
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/XXXXXXXX.json');
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->addScope(SCOPES);
$client->setSubject('me@mydomain.com');
$httpClient = $client->authorize();
$response = 
$httpClient->get('https://www.googleapis.com/admin/directory/v1/users/me@mydomain.com');
print $response->getBody();

这是我得到的回复：

Uncaught exception 'GuzzleHttp\Exception\ClientException' with message 'Client error: `POST https://www.googleapis.com/oauth2/v4/token` resulted in a `401 Unauthorized` response:
{
 "error": "unauthorized_client",
 "error_description": "Unauthorized client or scope in request."
}

在管理控制台 > 安全 > 管理 API 客户端访问中，我输入了具有这些 API 范围的客户端 ID：

View and manage the provisioning of groups on your domain
https://www.googleapis.com/auth/admin.directory.group
View and manage the provisioning of users on your domain
https://www.googleapis.com/auth/admin.directory.user
Groups Settings
https://www.googleapis.com/auth/apps.groups.settings 

我用于该主题的帐户 ('me@mydomain.com') 是该域的超级管理员。为服务帐户启用了域范围的委派。

我在这里忽略了什么？任何帮助将不胜感激。

检查您是否已在管理控制台中启用 API，同时检查您的 Google Project for Admin SDK 中是否已启用该服务。
