【问题描述】：

我想在我的网站标题和其他一些视图中显示未读消息的数量。为此，我编写了一个全局中间件，但该中间件无法访问已注册用户的身份验证信息。

<?php

namespace PTA_OIMS\Http\Middleware;

use Illuminate\View\Factory;
use Closure;
use Illuminate\Contracts\Auth\Guard;
use PTA_OIMS\Kartable;
use Session;

class UnreadMessage

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */

    protected $auth;
    protected $view;

    public function __construct(Guard $auth, Factory $view)
    
        $this->auth = $auth;
        $this->view = $view;
    

    public function handle($request, Closure $next)
    
        $unreadMessage = NULL;
        $user = $this->auth->check();
        if (!empty($user)) 
            $unreadMessage = Kartable::
            where('id_reciver', '=',
                Session::get('personnel_info.0')->box_id)
                ->whereBetween('status', [1, 2])
                ->where('view_date', '=', Null)
                ->count();
        
        $this->view->share('unreadMessage', $unreadMessage);
        return $next($request);
    

更新：

<?php

namespace PTA_OIMS\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel

    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array
     */
    protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \PTA_OIMS\Http\Middleware\UnreadMessage::class,

    ];

    /**
     * The application's route middleware groups.
     *
     * @var array
     */
    protected $middlewareGroups = [
        'web' => [
            \PTA_OIMS\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \PTA_OIMS\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

    /**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \PTA_OIMS\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

    ];

【问题讨论】：

从外观使用`\Auth`

Auth::check() 返回一个布尔值，而不是用户实例，您希望在检查后使用 Auth::user() 获取用户。

这不属于中间件。中间件用于处理 HTTP 请求和响应。它更适合放在 view composer 中：laravel.com/docs/master/views#view-composers

【参考方案1】：

尝试使用全局auth() helper：

$user = auth()->check();

@RohullahRajaeeRad 请显示app\Http\Kernel.php你使用。
