Check if user is logged in laravel 4
提问by user1424508
Hi I am implementing a chat/inbox feature on my website. When users are not logged in and receive a message from another user, the website will send an email to the recipient of the message. However when the user is logged in it won't.
嗨，我正在我的网站上实施聊天/收件箱功能。当用户未登录并收到来自其他用户的消息时，网站将向消息接收者发送电子邮件。但是，当用户登录时，它不会。
My questions is how do I tell whether a user is logged in or not? For example, if a user is logged in and then closes the browser my backend wouldn't know anything.
我的问题是如何判断用户是否登录？例如，如果用户登录然后关闭浏览器，我的后端将一无所知。
Btw I'm building a Angularjs SPA with a restful API in Laravel 4.?
顺便说一句，我正在 Laravel 4 中构建一个带有宁静 API 的 Angularjs SPA。？

if you are using build-in Laravel Auth:
如果您使用内置 Laravel Auth：
if(Auth::check())
{
//do something
}
if you are using Sentry:
如果您使用的是哨兵：
if(Sentry::check())
{
//do something
}

I suggest using Ajax to pingthe DB when the user is logged in. Add a last_logged_incolumn of type DateSo when the users are logging in they update their last_logged_infield to the current date. You can do this Ajax as often as you like (very minimal performance issues). To see if a user is logged in simply check the last_logged_indate and compare it to the current date minus some time (1 minutes)..
我建议在用户登录时使用 Ajax ping数据库。添加一个last_logged_in类型为DateSo的列，当用户登录时，他们将其last_logged_in字段更新为当前日期。您可以随心所欲地执行此 Ajax（极少的性能问题）。要查看用户是否登录，只需检查last_logged_in日期并将其与当前日期减去一些时间（1 分钟）进行比较。
I would not suggest using it to email users because it may result in lots of spam.
You can use the is_logged_infield in addition but don't use it on it's own.
我不建议使用它给用户发送电子邮件，因为它可能会导致大量垃圾邮件。您可以is_logged_in另外使用该字段，但不要单独使用它。
