Authentication 是否有一种自定义laravel auth的方法来验证用户是否预先存储在旧表中？

我正在将一个纯PHP应用程序重构到Laravel。我已经做了拉威尔·奥特。它起作用了。但是，我需要一种将旧用户和密码迁移到新表的方法。我的想法是，在登录后，验证用户是否存储在旧表中，如果是，则在新表中插入该用户，并使用laravel auth进行处理。我可以在LoginController中重写登录的方法来进行这些更改吗？可能吗？

我不得不覆盖登录方法，添加函数migrationUserModelInternet（$request）

受保护的功能登录（请求$Request）{

    $this->validateLogin($request);

    $this->migrationUserModelInternet($request);

    // If the class is using the ThrottlesLogins trait, we can automatically throttle
    // the login attempts for this application. We'll key this by the username and
    // the IP address of the client making these requests into this application.
    if ($this->hasTooManyLoginAttempts($request)) {
        $this->fireLockoutEvent($request);

        return $this->sendLockoutResponse($request);
    }

    if ($this->attemptLogin($request)) {
        return $this->sendLoginResponse($request);
    }

    // If the login attempt was unsuccessful we will increment the number of attempts
    // to login and redirect the user back to the login form. Of course, when this
    // user surpasses their maximum number of attempts they will get locked out.
    $this->incrementLoginAttempts($request);

    return $this->sendFailedLoginResponse($request);
}
