namespace AppHttpMiddleware;

use Closure;

use Auth;

class RoleMiddleware

{

/**

* Handle an incoming request.

*

* @param IlluminateHttpRequest $request

* @param Closure $next

* @return mixed

*/

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

{

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

return redirect()->route('home');

}

return $next($request);

}

}

namespace AppHttp;

use IlluminateFoundationHttpKernel as HttpKernel;

......

'role' => AppHttpMiddlewareRoleMiddleware::class,

];

}

Route::get('home', ['as'=>'home','uses'=>'HomeController@index']);


Route::group(['middleware' => 'role:admin'], function () {

});

OR

Route::get('home', ['as'=>'home','uses'=>'HomeController@index']);


Route::get('admins', ['as'=>'admins','uses'=>'HomeController@admins','middleware' => 'role:admin']);
