go-zero can't support two different Methods with the same path.

[cliffwoodave14]

Describe the bug
If I define two routes with the same path content, but with different Method, then go-zero always returns 405 Method Not Allowed for one method. As we know, for a resource, we should support GET, PUT, even HEAD method on the same resource. We should not expect 405 error unless the method is not in the list(Head, Get, Put, Patch, Post...).

To Reproduce
Steps to reproduce the behavior, if applicable:

1. The code is

   server.AddRoutes(
   []rest.Route{
   {
   Method: http.MethodHead,
   Path: "/subscriptions/:ID/groups/:groupName",
   Handler: HeadGroupHandler(serverCtx),
   },
   {
   Method: http.MethodPut,
   Path: "/subscriptions/:ID/groups/:groupName",
   Handler: GetGroupHandler(serverCtx),
   },

2. The error is
   PUT https://xxxx.com/subscriptions/8ecadfc9-d1a3-4ea4-b844-0d9f87e4d7c8/groups/test-group\n--------------------------------------------------------------------------------\nRESPONSE 405: 405 Method Not Allowed\nERROR CODE

Expected behavior
Should not return 405 error.

Screenshots
If applicable, add screenshots to help explain your problem.

Environments (please complete the following information):

• OS: [e.g. Linux]
  Linux
• go-zero version [e.g. 1.2.1]
• 1.6.5
• goctl version [e.g. 1.2.1, optional]

hi, I tested your route without 405. Do you need to check the path of the request, or the request method? @cliffwoodave14

routers.go

func RegisterHandlers(server *rest.Server, serverCtx *svc.ServiceContext) {
	server.AddRoutes(
		[]rest.Route{
			{
				Method:  http.MethodGet,
				Path:    "/from/:name",
				Handler: TestHandler(serverCtx),
			},
			{
				Method:  http.MethodHead,
				Path:    "/subscriptions/:ID/groups/:groupName",
				Handler: HeadGroupHandler(serverCtx),
			},
			{
				Method:  http.MethodPut,
				Path:    "/subscriptions/:ID/groups/:groupName",
				Handler: GetGroupHandler(serverCtx),
			},
		},
	)
}

test.api

type Request {
	Name string `path:"name,options=you|me"`
