Laravel:一次只允许每个用户一个会话 [英] Laravel: Only allowing one session per user at a time

问题描述

在Laravel 4中，每个用户一次只能允许一个会话吗?

Is it possible in Laravel 4 to only allow one session per user at a time?

例如，如果用户登录并且已经有其他会话，则这些其他会话将被取消，最好是通过一种方式来提醒他们为什么?

Eg, so if User logs in and already has other Sessions, those other Sessions are cancelled, preferably with a way to alert them why?

如果有帮助，我正在Amazon ElastiCache上使用Redis会话驱动程序.

I'm using the Redis session driver on Amazon ElastiCache if that helps as well.

推荐答案

是的，我为我的项目做过类似的事情.

Yeah, I did similar for my project.

因此，在这种情况下，您需要向用户模型添加另一个属性:last_sessid.

So, you need add to your user model another attribute in this case: last_sessid.

public function swapping($user) {
    $new_sessid   = \Session::getId(); //get new session_id after user sign in
    $last_session = \Session::getHandler()->read($user->last_sessid); // retrive last session

    if ($last_session) {
        if (\Session::getHandler()->destroy($user->last_sessid)) {
            // session was destroyed
        }
    }

    $user->last_sessid = $new_sessid;
    $user->save();
}

现在，如果用户有一个活动会话，并且登录了另一个浏览器，则第一个会话将被删除.

Now, if the user has an active session, and signs in another browser, the first session will be removed.
