Lumen开发：简单实现auth用户认证

打开bootstrap/app.php，取消下面两段代码的注释，

$app->middleware([
   App\Http\Middleware\ExampleMiddleware::class
]);

$app->routeMiddleware([
   'auth' => App\Http\Middleware\Authenticate::class,
]);

打开router/web.php，加入以下路由代码，

$app->group(['middleware' => 'auth'], function ($app){
	$app->get('hello', function() {
	    echo 'hello, world';
	});
});

访问 域名/hello，显示 hello, world。
