自定义身份验证中间件-Laravel 5

Question

The delivered auth middleware that comes with Laravel 5 is great for user-only routes and controllers, however I want to add the ability to also check if the user is an administrator.

Currently, in my controllers, I have this for every class:

if (Auth::user()->level <= 1) {
    // admin can do these actions
} else {
    // redirect
}

It's very redundant and I'd like to look at what my options are. Since I want to retain the original auth middleware for user authentication, should I be building a new one for administrator authentication, or can I make some simple change in the original auth middleware that can account for my code above?

Middleware in Laravel 5.0 do not support arguments (this will be added in the upcoming 5.1 release).

Your options are to either create a separate middleware for this, or use route filters.

You can create a route filter by putting this in your RouteServiceProvider 's boot method:

$router->filter('userLevel', function($route, $request, $level)
{
    $user = auth()->user();

    if ( ! $user || $user->level > $level)
    {
        return response('Unauthorized', 401);
    }
});

Then use that filter in your routes:

Route::group(['before' => 'userLevel:1'], function($router)
{
    // define routes...
});
