使用大猩猩Mux子路由器时如何获取完整的请求路径？

I am using the gorilla toolkit mux to route requests, i have a couple of subroutes using path prefix, problem is i want to get the full request path but req.URL.path only has the part of the url after the path prefix so how do i get a path including the path prefix? thanks in advance

Try req.Referer()

It is retrieved from an header value and you are not guaranteed that it is not spoofed.
