thinkphp6 多级控制器报错

Question

开启了多级控制器

不使用路由，按照.语法书写url。以下这样书写地址就是正常的

http://serverName/index.php/user.blog/index

但是，使用路由的时候报错

Route::get('user/blog','user.blog/index');

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.
