I was just wondering if anyone knew how to check for session timeout in Laravel.

我只是想知道是否有人知道如何在Laravel中检查会话超时。

You can check whether the session has a specific item:

您可以检查会话是否有特定的项目：

if (Session::has('name'))
{
     $name = Session::get('name');
}

But you can't check whether the session has expired. It would be nice so that I can report back to the user in a more specific way. "Your session has timed out, please start again."

但您不能检查会话是否已过期。这将是很好的，这样我就可以以更具体的方式向用户报告。您的会话已超时，请重新开始。

Any thoughts?

有什么想法吗？

Just use the same logic as the session class itself.

只需使用与会话类本身相同的逻辑即可。

if ((time() - Session::activity()) > (Config::get('session.lifetime') * 60))
{
   // Session expired
}

Place this in your 'before' filter - and it will run on every request.

把它放在你的“之前”过滤器中--它就会在每次请求时运行。

Why not do this?

为什么不这样做呢？

if (!Session::has('name'))
{
     $sessionTimeout = 1;
}

If a session times out then the name will no longer be set. You can then write some code to respond to $sessionTimeout == 1;

如果会话超时，则不再设置名称。然后您可以编写一些代码来响应$sessions. exe == 1;

BTW,
Specifically if you need the session lifetime,

顺便说一句，特别是如果您需要会话生存期，

Use this:

使用这个：

{{ session('lifetime') }}

When describing this,

在描述这一点时，

Use this:

使用以下命令：

session(['User' => $user, 'lifetime' => 3600]);

In Laravel 8 onwards, the best solution seems to be something like this:

从Laravel 8开始，最好的解决方案似乎是这样的：

if(session()->missing("name") && session()->missing("email")) {
   // Replace with your own logic to handle the missing session       
   throw SessionNotFoundException;
}

...where both name and email are two session keys that should always be present in the session. Checking two keys is more robust and prevents the condition triggering when just one of them may be missing due to a bug.

...其中姓名和电子邮件都是应该始终出现在会话中的两个会话密钥。检查两个键更可靠，并防止在其中一个键由于错误而丢失时触发条件。
