This is an adaption of the ACL strategy described here: [ http://ollieread.com/blog/2014/03/18/a-simplified-laravel-acl/ ] for Laravel 5.

##angular.js

In order to the `$request->ajax();` method work properly with angular.js, you must set the `X-Requested-With` header to `XMLHttpRequest` on every ajax requests.

This can be done on the configuration phase of your app, like so:

    // change 'app' to your module's name
    angular.module('app').config( ['$httpProvider', function ( $httpProvider) {
        // sets the X-Request-With to be sent on every ajax request with a value of XMLHttpRequest
        $httpProvider.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
    } ] );

AclPermitted.php

<?php namespace App\Services;

use App\User;

class AclPermitted
{
    public static function verify( $permission )
    {
        /** @var User $user */
        $user = app( 'auth' )->user();

        $user->load( 'groups', 'groups.permissions' );

        foreach ( $user->groups as $group )
        {
            if ( $group->permissions->contains( $permission ) )
            {
                return TRUE;
            }
        }

        return FALSE;
    }
}

AclPermittedMiddleware.php

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Contracts\Routing\Middleware;

use App\Services\AclPermitted;

class AclPermittedMiddleware implements Middleware
{
    public function handle( $request, Closure $next )
    {
        $route     = $request->route();
        $permitted = AclPermitted::verify( $route->getName() );

        if ( !$permitted )
        {
            if ( $request->ajax() )
            {
                return response()->make( 'Forbidden.', 403 );
            }
            else
            {
                return redirect()->back()->withErrors( 'Not authorized.' );
            }
        }

        return $next( $request );
    }
}

Kernel.php

<?php namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel {

	/**
	 * The application's global HTTP middleware stack.
	 *
	 * @var array
	 */
	protected $middleware = [
		'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
		'Illuminate\Cookie\Middleware\EncryptCookies',
		'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
		'Illuminate\Session\Middleware\StartSession',
		'Illuminate\View\Middleware\ShareErrorsFromSession',
		'App\Http\Middleware\VerifyCsrfToken',
	];

	/**
	 * The application's route middleware.
	 *
	 * @var array
	 */
	protected $routeMiddleware = [
		'auth' => 'App\Http\Middleware\Authenticate',
		'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
		'guest' => 'App\Http\Middleware\RedirectIfAuthenticated',
		'acl.permitted'  => 'App\Http\Middleware\AclPermittedMiddleware', // register an alias to our middleware
	];

}

routes.php

<?php

// sample usage

$router->get('api/articles', [
	'uses' => 'Api\ArticleController@index',
	'as' => 'articles.index',
	'middleware' => ['auth', 'acl.permitted'],
]);
