Laravel 5路线不起作用

I'm migrating from Laravel 4 to Laravel 5.

Only following is working:

Route::get('/some-url', function(){
    echo "Some text";
});

Following is not working:

Route::get('/get-customer-info', 'CustomerController@info');

I created the controller in: app\Http\Controllers\CustomerController.php

So, whenever I redirect to a controller, it always set object not found Here is my controller:

<?php
namespace App\Http\Controllers;

class CustomerController extends Controller
{
   function __construct()
   {
       View::share('root', URL::to('/'));
   }

   public function info()
   {
       echo "ok";
   }
}

I moved index.php file to the root. Here is the index.php file on the

<?php

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(

$response->send();

$kernel->terminate($request, $response);
