Php 如何将文件放入某个google drive帐户？

我正在使用PHP将一些运行时创建的文件放在特定的Google Drive帐户上。
如果我用一个帐户登录谷歌，然后启动我的脚本，这些文件将被上传到这个帐户上，即使我使用不同帐户的客户ID和密码

用例：
我已经登录了a@gmail.com，我使用我的脚本并将文件发送到a@gmail.com的谷歌硬盘，而不是b@gmail.com谷歌硬盘

如何将这些文件上载到b@gmail.com帐户，即使我已登录a@gmail.com帐户

谢谢

前代码

    <?php
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_DriveService.php';

$drive = new Google_Client();

$drive->setClientId(/*client id*/);
$drive->setClientSecret(/*client secret*/);
$drive->setRedirectUri(/*redirect uri (the same URI in the API configuration)*/); 
$drive->setScopes(array('https://www.googleapis.com/auth/drive'));

$gdrive = new Google_DriveService($drive);

file_put_contents('token.json', $drive->authenticate());

$drive->setAccessToken(file_get_contents('token.json'));

$file = new Google_DriveFile();
$file->setTitle('My document');
$file->setDescription('A test document');
$file->setMimeType('text/plain');


$createdFile = $service->files->insert($file, array(
  'data' => 'example',
  'mimeType' => 'text/plain',
));


return true;

您是否尝试过要与我们共享的内容？如果您想将内容上载到多个帐户，您可以尝试使用服务帐户。它适用于谷歌应用程序，但可能无法满足您的需求。您可能需要提供更多关于您的目标的信息：
