Laravel 5.6中间件似乎不起作用

Question

有人可以检查我的代码吗，我不知道为什么它不起作用。 网站上有带有密码字段的正在建设中的页面。只允许受邀用户访问其他页面，他们必须输入发送给他们的密码。 如果密码不正确或丢失，它们将被重定向回构建页面。这部分没问题。但是，当用户输入正确的密码时，他将获得“找不到页面”。 我的中间件：

    namespace App\Http\Middleware;

    use Closure; 
    use Illuminate\Support\Facades\Cookie;

    class CheckInvitation
    {
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        \Log::debug($_COOKIE['invitation']);
        if ($request->hasCookie('invitation')) {
            \Log::info('Found cookie');
            return $next($request);
        } else {
            return redirect('/under-construction');
        }

    }
}

控制器

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Cookie;

class UnderConstructionController extends Controller
{
public function create() {
    return view('construction');
}

public function check(Request $request) {

    if ($request->invitation_pass === 'somepass') {
        //dd('pass works');
        \Log::info($_COOKIE);
        Cookie::queue(Cookie::make('invitation', 'You are invited', 
180));
        return redirect('/home');
    } else {
        return redirect('/under-construction');
    }
}
}
