Laravel中间件增强了路由模型绑定的安全性

Question

任何人都可以想到一种灵活的中间件方式或者如果＆＃39;如果＆＃39;声明，以便我们可以更安全地使用路由模型绑定？

Route::get('/channel-groups/{channelGroup}/channels/{channel}', [
    'as'   => 'channel-groups',
    'uses' => function(\App\Distribution\UserConfigurations\ChannelGroup $channelGroup, \App\Distribution\UserConfigurations\Channel $channel){

        //@todo: middleware
        if(!$channelGroup->Channels->contains($channel)){
            return abort(401, 'Unauthorized');
        }

        return $channel;
    }
]);
