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
