Google drive Upload返回-(403)权限不足

Question

我正在尝试使用服务帐户上传文件到谷歌驱动器，但我得到错误，如

(403)权限不足错误

虽然从驱动器获取文件列表工作正常

require_once 'google-api-php-client-master/src/Google/autoload.php';
require_once 'google-api-php-client-master/src/Google/Service.php';
session_start();
$client = new Google_Client();
$client->setAuthConfigFile('client_secrets.json');
$service_account_name = '[e-mail]';
$key_file_location = 'key.p12'; //key.p12
$key = file_get_contents($key_file_location);;
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
    $client->setAccessToken($_SESSION['access_token']);
    //$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
    //$client->setScopes(array('https://www.googleapis.com/auth/drive'));
    $cred = new Google_Auth_AssertionCredentials(
    $service_account_name,
    array('https://www.googleapis.com/auth/drive'),
    $key);
    $client->setAssertionCredentials($cred);
    $client->setAccessType("offline");
    $file = new Google_Service_Drive_DriveFile();
    $file->setTitle(uniqid().'.jpg');
    $file->setDescription('A test document');
    $file->setMimeType('image/jpeg');
    $data = file_get_contents('a.jpg');
    $service = new Google_Service_Drive($client);
    $createdFile = $service->files->insert($file, array(
          'data' => $data,
          'mimeType' => 'image/jpeg',
          'uploadType' => 'multipart'
        ));
    print_r($createdFile);
} 
else
{
  $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/googledrive/oauth2callback.php';
  header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

我在论坛上回顾了类似的问题，并尝试了建议，但似乎没有任何工作。

代码有什么问题吗?

将Google Drive Scope更改为

Google_Service_Drive::DRIVE

在PHP中

$client->addScope(Google_Service_Drive::DRIVE);
