【中文标题】如何在 LUMEN 中使用 GATE 立面(Laravel 6.2)【英文标题】:How to use GATE facades in LUMEN (Laravel 6.2) 【发布时间】:2020-04-02 10:16:33 【问题描述】:我正在尝试使用 Lumen 创建 ACL。 我想使用内置的门/策略来做到这一点。 我一直在关注官方的 Lumen Docs: https://lumen.laravel.com/docs/6.x/authorization
和 Laravel 文档: https://laravel.com/docs/6.x/authorization
这样做。他们说我需要同时注册门面和门面才能使用 Gates。
我的 AuthServiceProvider.php 中有以下代码:
<?php
namespace App\Providers;
use App\User;
use Firebase\JWT\JWT;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Gate;
//use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Illuminate\Http\Request;
class AuthServiceProvider extends ServiceProvider
/**
* Register any application services.
*
* @return void
*/
public function register()
//
/**
* Boot the authentication services for the application.
*
* @return void
*/
public function boot()
// Here you may define how you wish users to be authenticated for your Lumen
// application. The callback which receives the incoming request instance
// should return either a User instance or null. You're free to obtain
// the User instance via an API token or any other method necessary.
$this->app['auth']->viaRequest('api', function ($request)
$key = 'pawifjopawiejfpoaiwejfpoji';
$jwt = preg_replace('/^Bearer (.*)/', '$1', $request->header('Authorization'));
$decoded = JWT::decode($jwt, $key, ['HS256']);
return User::where('email', $decoded->email)->first();
);
$this->registerPolicies();
Gate::define('edit-settings', function($user)
return $user->isAdmin;
);
我的 bootstrap/app.php 设置如下,$app->withFacades()
未注释:
<?php
require_once __DIR__.'/../vendor/autoload.php';
(new Laravel\Lumen\Bootstrap\LoadEnvironmentVariables(
dirname(__DIR__)
))->bootstrap();
/*
|--------------------------------------------------------------------------
| Create The Application
|--------------------------------------------------------------------------
|
| Here we will load the environment and create the application instance
| that serves as the central piece of this framework. We'll use this
| application as an "IoC" container and router for this framework.
|
*/
$app = new Laravel\Lumen\Application(
dirname(__DIR__)
);
$app->withFacades();
$app->withEloquent();
/*
|--------------------------------------------------------------------------
| Register Container Bindings
|--------------------------------------------------------------------------
|
| Now we will register a few bindings in the service container. We will
| register the exception handler and the console kernel. You may add
| your own bindings here if you like or you can make another file.
|
*/
$app->singleton(
Illuminate\Contracts\Debug\ExceptionHandler::class,
App\Exceptions\Handler::class
);
$app->singleton(
Illuminate\Contracts\Console\Kernel::class,
App\Console\Kernel::class
);
/*
|--------------------------------------------------------------------------
| Register Middleware
|--------------------------------------------------------------------------
|
| Next, we will register the middleware with the application. These can
| be global middleware that run before and after each request into a
| route or middleware that'll be assigned to some specific routes.
|
*/
// $app->middleware([
// App\Http\Middleware\ExampleMiddleware::class
// ]);
$app->routeMiddleware([
'auth' => App\Http\Middleware\Authenticate::class,
]);
/*
|--------------------------------------------------------------------------
| Register Service Providers
|--------------------------------------------------------------------------
|
| Here we will register all of the application's service providers which
| are used to bind services into the container. Service providers are
| totally optional, so you are not required to uncomment this line.
|
*/
// $app->register(App\Providers\AppServiceProvider::class);
$app->register(App\Providers\AuthServiceProvider::class);
// $app->register(App\Providers\EventServiceProvider::class);
/*
|--------------------------------------------------------------------------
| Load The Application Routes
|--------------------------------------------------------------------------
|
| Next we will include the routes file so that they can all be added to
| the application. This will provide all of the URLs the application
| can respond to, as well as the controllers that may handle them.
|
*/
$app->router->group([
'namespace' => 'App\Http\Controllers',
], function ($router)
require __DIR__.'/../routes/web.php';
);
return $app;
当我现在使用 RESTClient (www.restclient.net) 对我的 Lumen API 运行任何 http 请求时,我收到以下错误:
Call to undefined method App\Providers\AuthServiceProvider::registerPolicies()
我在这个问题上搜索了很多,并找到了一些解决方案,但没有一个对我有用。 请帮忙
【问题讨论】:
因为你的 AuthServiceProvider 没有那个方法......它没有扩展 Laravel 使用的提供者,它只是扩展了基础服务提供者 @lagbox 谢谢,但是我如何/在哪里可以在流明代码库中处理这个问题? 如果您没有任何政策,即使registerPolicies
确实存在,也没有理由运行它
【参考方案1】:
您的提供商没有该方法。这是 Laravel 用作 AuthServiceProvider
基础的整个 AuthServiceProvider
:
use Illuminate\Support\Facades\Gate;
use Illuminate\Support\ServiceProvider;
class AuthServiceProvider extends ServiceProvider
/**
* The policy mappings for the application.
*
* @var array
*/
protected $policies = [];
/**
* Register the application's policies.
*
* @return void
*/
public function registerPolicies()
foreach ($this->policies() as $key => $value)
Gate::policy($key, $value);
/**
* Get the policies defined on the provider.
*
* @return array
*/
public function policies()
return $this->policies;
registerPolicies
没有做任何特别的事情。它只是通过$policies
旋转并注册它们;你可以自己做。
“与 Laravel 不同,Lumen 在其
AuthServiceProvider
上没有$policies
数组。但是,您仍然可以从提供者的boot
方法中调用Gate
外观上的policy
方法” - @ 987654321@
