通过运行cron作业访问谷歌驱动器

Question

这里我使用谷歌驱动器备份我的数据在驱动器上，为此我写了一个脚本，我想通过cronjob运行。但它需要access_token来访问谷歌驱动器。我在我的数据库中保留访问令牌并将其提供给备份文件，但该令牌未通过cronjob进行更新。但是当我在浏览器上运行它然后工作正常。我想通过没有更新的cronjob来更新令牌。

    $client = new Google_Client();
    $client->setAuthConfigFile('client_secret.json');
    $client->setAccessType("offline");
    $client->setRedirectUri('https://******/controllers/oauth2callback.php');
    $client->addScope(Google_Service_Drive::DRIVE);

    if (! isset($_GET['code'])) {
        $auth_url = $client->createAuthUrl();
        header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
    } else {
        $client->authenticate($_GET['code']);
        $token_data = $client->getAccessToken();
        update_token($token_data);
        $redirect_uri = 'https://******/controllers/db_backup.php?action=backup';
        header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
    }

        $conn = $db->connect('pf_central');
