how to capture a Not Allowed method error

[l12ab]

当定义了一个路由，method限制为GET，如果使用其他方式访问，比如POST，会输出Forbidden。 因为想要用一个统一的错误页面来展示错误信息，包括panic、其他400以上的status代码、以及这个MethodNotAllowed 。

尝试过使用中间件来实现，用自带的后置中间件ghttp.MiddlewareHandlerResponse，还是自己改写的前置中间件，都无法捕捉到这个Forbidden。 请问如何实现？

另外，用过其他框架，比如fiber，它有个默认的错误处理controller，所有的错误、异常都会用这个controller展示，并且可以自定义这个controller。那么gf能不能也实现这个

When a route is defined, the method is limited to GET. If accessed using other methods, such as POST, Forbidden will be output. Because I want to use a unified error page to display error information, including panic, other status codes of more than 400, and this MethodNotAllowed.

I have tried to use middleware to implement it, whether using the built-in post-middleware ghttp.MiddlewareHandlerResponse or the pre-middleware I rewrote, but I can't catch this Forbidden. How to achieve this?

In addition, I have used other frameworks, such as fiber, which has a default error handling controller. All errors and exceptions will be displayed using this controller, and this controller can be customized. So can gf also achieve this?
