如何在net / http中编写/ api / v1 / users / id / {id}？

Question

For example, I want to do /api/v1/users/id/{id}.

At the moment, I have this:

mux := http.NewServeMux()
mux.Handle("/api/v1/users", HandleUsersV1{db: db, mux: mux})
log.Fatal(http.ListenAndServe(fmt.Sprintf("%s%d", ":", portNumber), mux))

I want:

mux := http.NewServeMux()
mux.Handle("/api/v1", HandleV1{})

And then in HandleV1:

mux.HandleFunc("/users/{id}", handler)

I know Gorilla Mux can do it for me with PathPrefix, but I prefer net/http.

The standard net/http does not support dynamic path segments, so /{id} is not gonna work the way you might imagine. As for the prefix thing, you can use this https://golang.org/pkg/net/http/#StripPrefix.

v1mux := http.NewServeMux()
v1mux.HandleFunc("/users/", handler)

mux := http.NewServeMux()
mux.Handle("/api/v1/", http.StripPrefix("/api/v1", v1mux))

log.Fatal(http.ListenAndServe(fmt.Sprintf("%s%d", ":", portNumber), mux))
