问题描述

我正在尝试在Laravel 5.3中创建一个自定义错误页面.我想要检索存储在 Session 中的某些变量，例如 Session :: get("username")，但是我得到的是一个空变量.

I am trying to create a custom error page in Laravel 5.3. I wanted the retrieve some variable stored in the Session like Session::get("username"), however what I get is an empty variable.

我应该如何在Laravel的自定义错误页面中获取任何 Session 变量，还是不可能?

How am I suppose to get any Session variable in a custom error page in Laravel or is it not possible?

推荐答案

由于Laravel找不到路由，因此您没有通过中间件 \ Illuminate \ Session \ Middleware \ StartSession (即默认情况下位于 web 中间件组中)，因此不会启动会话.

As Laravel did not find the route, you did not pass through the middleware \Illuminate\Session\Middleware\StartSession (which is by default in web middleware group), so your session is not started.

要初始化会话，请将 \ Illuminate \ Session \ Middleware \ StartSession :: class 从 web 移到 $ middleware 中，code> Kernel.php :

To have your session initialized, move \Illuminate\Session\Middleware\StartSession::class, from web to $middleware in Kernel.php:

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Session\Middleware\StartSession::class,
],

$ midleware 中的中间件始终运行，因此即使未找到路由，您的会话也会被初始化.

Middlewares in $midleware are always run so your session will be initialized, even if the route is not found.
