路由::身份验证未包含在中间件中

Route::get('/', function () {
    return view('welcome');
});
Route::auth();
Route::get('/home', 'HomeController@index');

拉维尔routes.php .因此，当我查看Laravel 5.2的身份验证示例时，我总是看到Route::auth();和Route::get('/home', 'HomeController@index')封装在Route::group(['middleware' => ['web']], function () {事物{中。但是每当我使用这些命令时php artisan make:auth它所做的就是创建我上面显示的命令。

为什么会这样做的任何线索？它工作正常，但我不是 100% 确定它是否正常运行。但我可以告诉你，我可以正确登录和注册。他们对拉拉维尔做了任何改变吗？
