Silex：简单的身份验证用户

Question

我目前正在开发Silex框架下的应用程序。我想使用一个身份验证系统，但我是这个框架的新手，即使我要在文档中潜入好几天，我仍然不了解所有内容......

我的申请非常基本。 root是一个连接页面，用户必须连接，然后根据它们在MYSQL数据库上的类型（3类型用户）重定向到3页中的一个，因此，在/home.

    $templates = array(

        'errors/'.substr($code, 0, 2).'x.html.twig',
        'errors/'.substr($code, 0, 1).'xx.html.twig',
        'errors/default.html.twig',
    );

    return new Response($app['twig']->resolveTemplate($templates)->render(array('code' => $code)), $code);
});

从哪里开始利用Silex提出的SecurityServiceProvider系统？

问候。
