Question

我正在关注制定访问级别限制的教程：

https://gist.github.com/amochohan/8cb599ee5dc0af5f4246

我能够以某种方式使它工作，但我需要做的事情，而不是在教程中。

前提是我已按照本教程进行操作。我已经设置了这条资源路线：

Route::group(['middleware' => ['auth', 'roles'], 'roles' => ['Administrator']], function()
{
    Route::resource('changeschedule', 'ChangeScheduleController', ['only' => ['index'], 'except' => ['create']]);
});

所以我想要的只是将roles中间件应用于资源路由，但在该资源中使用特定路由只是让我说我只想应用于index我上面有这条路线。

当我去：

http://localhost/hrs/public/changeschedule

它工作正常，中间件roles工作正常。但是当我去的时候为什么呢？

http://localhost/hrs/public/changeschedule/create

我正在

NotFoundHttpException in RouteCollection.php line 161:

所以我找不到路线错误。这是为什么？但是当我做的时候

Route::group(['middleware' => ['auth', 'roles'], 'roles' => ['Administrator']], function()
{
    Route::resource('changeschedule', 'ChangeScheduleController');
});

然后它工作正常，但中间件应用于所有：

index, create, update, edit, delete

我希望它只在索引中。

我的代码：

Kernel.php

protected $routeMiddleware = [
    'auth'          => \App\Http\Middleware\Authenticate::class,
    'auth.basic'    => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest'         => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'roles'         => \App\Http\Middleware\CheckRole::class,
];

CheckRole.php

<?php namespace App\Http\Middleware;

use Closure;

class CheckRole{

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */

    public function handle($request, Closure $next)
    {
        // Get the required roles from the route
        $roles = $this->getRequiredRoleForRoute($request->route());
        // Check if a role is required for the route, and
        // if so, ensure that the user has that role.
        if($request->user()->hasRole($roles) || !$roles)
        {
            return $next($request);
        }
        return response([
            'error' => [
                'code' => 'INSUFFICIENT_ROLE',
                'description' => 'You are not authorized to access this resource.'
            ]
        ], 401);
    }

    private function getRequiredRoleForRoute($route)
    {
        $actions = $route->getAction();
        return isset($actions['roles']) ? $actions['roles'] : null;
    }
}

您可以尝试这个，创建一个构造函数并从那里添加中间件，例如：

public function __construct()
{
    $this->middleware('auth');

    $this->middleware('roles:administrator', ['only' => ['index']]);  
}

阅读documentation。

更新（middleware :: handle方法中的第三个参数可以接受参数）：

public function handle($request, Closure $next, $role)
{
    // $role will catch the administrator or whatever you pass
}

您也可以在我的博客上查看这些examples/tutorials（关于中间件）。
