大猩猩mux子域

Question

How can I add a subdomain using gorilla mux and do something like:

http://api.localhost:8080/

I have tried

r := mux.NewRouter()
r.HandleFunc("/path", method).Methods("POST").Host("api.example.com")

But I don't want to pass the domain, because I need to change the domain each time I upload it to app engine, plus I think the above code will not work using the app engine framework.

You can define a subrouter for the subdomain:

s := r.Host("www.domain.com").Subrouter()
s.HandleFunc("/path", method).Methods("POST")
