问题描述

我在课堂上尝试使用 IlluminateHttpRequest 时遇到以下错误.

I am getting following error when I try to use IlluminateHttpRequest in my class.

错误:

PHP Fatal error:  Uncaught RuntimeException: A facade root has not been set. in /home/sasha/Documents/OffProjects/vetnearme/vetnearme/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:218

有问题的课程:

namespace AppAppComponents;

use IlluminateHttpRequest;

/**
 * This class will be used to build menu for admin panel based on the user role
 */
class AdminPanelMenu {

    static function menu(Request $request){

        $user = $request->user();

        if($user->hasRole['super_admin'])
            return self::superAdmin();

        if($user->hasRole['admin'])
            return self::admin();

        if($user->hasRole['user'])
            return self::user();

        return [];

    }

    private static function superAdmin()
    {
        return [
            'MAIN NAVIGATION',
        ];
    }

    private static function admin()
    {
        return [
            'MAIN NAVIGATION',
        ];
    }

    private static function user()
    {
        return [
            'MAIN NAVIGATION',
        ];
    }

}

我在这里做错了什么?

推荐答案

您需要创建一个新的应用容器,然后将其绑定到 Facade.

You need to create a new app container and then bind it to the Facade.

use IlluminateContainerContainer as Container;
use IlluminateSupportFacadesFacade as Facade;

/**
* Setup a new app instance container
*
* @var IlluminateContainerContainer
*/
$app = new Container();
$app->singleton('app', 'IlluminateContainerContainer');

/**
* Set $app as FacadeApplication handler
*/
Facade::setFacadeApplication($app);

流明:引导程序/app.php

in lumen:bootstrap/app.php

$app->withFacades();

祝你好运!
