NotFoundHttpException in Laravel middleware and controller - laravel

Question

I am new to laravel and learning basics from https://www.tutorialspoint.com/laravel/laravel_middleware.htm
After installation I have created RoleMiddleware and TestController.
RoleMiddleware.php
<?php
namespace App\Http\Middleware;
use Closure;
class RoleMiddleware
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next, $role)
{
echo "Role: ".$role;
return $next($request);
}
}
and TestController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class TestController extends Controller
{
//
public function index(){
echo "<br>Test Controller.";
}
}
and app\http\ routes.php
Route::get('/role',[
'middleware' => 'Role:editor',
'uses' => 'TestController#index',
]);
and in Kernel.php
protected $routeMiddleware = [
'auth' => \App\Http\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware \AuthenticateWithBasicAuth::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'Age' => \App\Http\Middleware\AgeMiddleware::class,
'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
'Role' => \App\Http\Middleware\RoleMiddleware::class,
'terminate' => \App\Http\Middleware\TerminateMiddleware::class,
];
After written all these code I have executed this using http://localhost:8000/role but it gives NotFoundHttpException, Please help me to solve this issue..

Answer 1

First of all you are using some older version of Laravel, as your routes are listed in app\http\routes.php file because in newer versions, it is actually routes\web.php file:
Then you made a mistake in your route:
Route::get('/role', ['middleware' => 'Role:editor', 'uses' => ]);
http routes must have a callback/closure, whether it is custom function or using a controller... Try with following basic options:
Route::get('/role', function() { return "Working"; });
Also check whether your route is not listed as excepted route
If its working, then play with middlewares!!!

Answer 2

i cant send a comment to ask for hole error ( bcs of my reputation )
but i write middle ware in this way . maybe its help you :
first make sure that $role is string or put it in json_encode ( on RoleMiddleware.php )
==> echo "Role: ".json_encode($role);
then change your rout to below :
Route::get('/role', 'TestController#index')->middleware('Role');
send back to me the result
