is /. and / same in go? Period(.) as id is not recognised

Question

I have two route handlers

v1Router. Path("/{id}"). Methods(http.MethodGet). Handler(r.getter())

v1Router. Path("/"). Methods(http.MethodGet). Handler(r.searcher())

when i am sending request at /"some id" it is working as expected ,but when i am sending request at /. the request is going through second handler.

Can anyone explain the above behaviour?

No, they aren't. Especially not as an URL path.

Answer 2

It's mentioned in the documentation for the net/http package, underneath http.ServeMux — though it's easy to miss.

Ref: https://pkg.go.dev/net/http#hdr-Request_sanitizing

Single and double periods are stripped from the route.
