Google adsense API (403） 用户没有 AdSense 帐户

个小时了，它总是返回（403）用户没有AdSense帐户，我正在尝试在我的网站上获取有关我的adsense的报告，Ps：它是服务器到服务器的连接

    require_once realpath(dirname(__FILE__) . '/../src/Google/autoload.php');
    require_once '../src/Google/Client.php';
    require_once '../src/Google/Service/AdSense.php';
    $client_email = 'xxx@xxx-1220.iam.gserviceaccount.com';
    $private_key = file_get_contents('adsense-xxxxx.p12');
    $scopes = array('https://www.googleapis.com/auth/adsense.readonly');
    $credentials = new Google_Auth_AssertionCredentials(
        $client_email,
        $scopes,
        $private_key,
    'notasecret'
    );
$client = new Google_Client();
$client->setAssertionCredentials($credentials);
if ($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion();
}
$service = new Google_Service_AdSense($client);
