流明角色中间件缺失论点

彼得

我是Lumen的新手，我正尝试通过Lumen docs中的示例获取角色中间件的功能：http : //lumen.laravel.com/docs/middleware#middleware-parameters

但是，一旦我将中间件添加到路由中，就像这样：

$app->get('/', ['middleware' => 'role:editor', 'uses' => 'IndexController@index']);

我得到错误：

at Application->Laravel\Lumen\{closure}('2', 'Missing argument 3 for App\Http\Middleware\RoleMiddleware::handle()', '/Users/peter/app/Http/Middleware/RoleMiddleware.php', '17', array('request' => object(Request), 'next' => object(Closure))) in RoleMiddleware.php line 17

当我删除中间件时，一切正常

$app->get('/', ['uses' => 'IndexController@index']);

在app.php中：

$app->middleware([
    Illuminate\Cookie\Middleware\EncryptCookies::class,
    Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    Illuminate\Session\Middleware\StartSession::class,
    Illuminate\View\Middleware\ShareErrorsFromSession::class,
    Laravel\Lumen\Http\Middleware\VerifyCsrfToken::class,
    App\Http\Middleware\RoleMiddleware::class
]);

App \ Http \ Middleware \ RoleMiddleware.php：

<?php

namespace App\Http\Middleware;

use Closure;

class RoleMiddleware
{
    public function handle($request, Closure $next, $role) // <-line 17
    {
        if (! $request->user()->hasRole($role)) {
            // Redirect...
        }
        return $next($request);
    }
}

希望有人能帮忙

似乎您必须将中间件注册为RouteMiddleware，而不是：

$app->middleware([
    Illuminate\Cookie\Middleware\EncryptCookies::class,
    Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    Illuminate\Session\Middleware\StartSession::class,
    Illuminate\View\Middleware\ShareErrorsFromSession::class,
    Laravel\Lumen\Http\Middleware\VerifyCsrfToken::class,
    App\Http\Middleware\RoleMiddleware::class
]);

它一定要是：

$app->middleware([
    Illuminate\Cookie\Middleware\EncryptCookies::class,
    Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    Illuminate\Session\Middleware\StartSession::class,
    Illuminate\View\Middleware\ShareErrorsFromSession::class,
    Laravel\Lumen\Http\Middleware\VerifyCsrfToken::class,
]);

$app->routeMiddleware([
    "role" => App\Http\Middleware\RoleMiddleware::class
]);

然后就可以了！
