=> Middleware can also receive additional parameters. For example, if your application needs to verify that the authenticated user has a given "role" before performing a given action, you could create an EnsureUserHasRole middleware that receives a role name as an additional argument.

​

=> Additional middleware parameters will be passed to the middleware after the $next argument:

​

<?php

namespace App\Http\Middleware;

use Closure;

class EnsureUserHasRole

{

    /**

     * Handle the incoming request.

     *

     * @param  \Illuminate\Http\Request  $request

     * @param  \Closure  $next

     * @param  string  $role

     * @return mixed

     */

    public function handle($request, Closure $next, $role)

    {

        if (! $request->user()->hasRole($role)) {

            // Redirect...

        }

        return $next($request);

    }
