這樣訪問沒有問題

Route::get('/register', 'index/register/register')->middleware('Login');
Route::get('/login', 'index/login/login')->middleware('Login');

手冊(cè)上也說了支持路由組的中間件形式

但是改成下面路由組的形式再訪問時(shí)就報(bào)錯(cuò)了 這是怎么回事？

Route::group('/test', function(){
    Route::get('/login', 'index/login/login');
    Route::get('/register', 'index/register/register');
})->middleware('Login');

中間件

<?php
namespace app\http\middleware;
use think\facade\Cookie;
use think\response;
use think\facade\Request;
class Login
{
    public function handle($request, \Closure $next)
    {
        if (Cookie::has('uid')) {
            return redirect('/');
        }else{
            return redirect('/login');
        }
        return $next($request);
    }
}
