问题描述

我正在其中一个中间件(用于 Laravel Web 应用程序)中覆盖 session.timeout 值，但它似乎不会影响会话超时.虽然如果我调试它会显示我已经覆盖的值.

I am overwriting session.timeout value in one of the middleware (for Laravel web app) but it doesn't seem to be affecting in terms of timing out a session. Though if I debug it shows value I have overwritten.

Config::set('session.lifetime', 1440);

默认值如下:

'lifetime' => 15,

我正在开发的网站对大多数用户的会话生命周期非常短，但对于选定的用户，我想提供更长的会话生命周期.

Website that I am working on has very short session lifetime for most of the users but for selected users I want to provide extended session lifetime.

推荐答案

似乎实现动态 lifetime 值的唯一方法是在会话启动之前在中间件中设置该值.否则为时已​​晚，因为应用程序 SessionHandler 已经使用默认配置值进行了实例化.

It seems the only way to accomplish a dynamic lifetime value, is by setting the value in middleware, before the session gets initiated. Otherwise its too late, as the application SessionHandler will have already been instantiated using the default config value.

namespace AppHttpMiddleware;

class ExtendSession
{
    /**
     * Handle an incoming request.
     *
     * @param  IlluminateHttpRequest  $request
     * @param  Closure  $next
     * @return mixed
     */
    public function handle($request, $next)
    {
        $lifetime = 2;
        config(['session.lifetime' => $lifetime]);
        return $next($request);
    }
}

然后在kernel.php文件中，在StartSession之前添加这个类.

Then in the kernel.php file, add this class prior to StartSession.

AppHttpMiddlewareExtendSession::class,
IlluminateSessionMiddlewareStartSession::class,
