Question

我正在尝试使用中间件类从数据库检索导航栏数据，以便我可以在应用程序中的任何位置访问它数据正常，但类将数据作为ajax响应打印而不是将其作为数组传递当我尝试导航应用程序中的任何路线时，它会打印出数据并消失并且未显示正确的视图

 <?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Response;
use App\Navigation;
use App\PrimaryNavigation ;
use Illuminate\Http\Request;
class NavigationMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $mainNavi = Navigation::with('PrimaryNavigation')->get() ;
        $subNavi = PrimaryNavigation::with('SubNavigation')->get() ;
        $navigation = [
            'main' => $mainNavi,
            'sub' =>$subNavi
        ];
        return Response($navigation);

    }
}

在内核类中注册的中间件类

<?php

namespace App\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 = [
        \App\Http\Middleware\TrustProxies::class,
        \App\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \App\Http\Middleware\NavigationMiddleware::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    ];
