How to filter some path from mux. Gorilla.Router

I would like to match only some of the routes from mux.Router and use the same handler for all the others. How can i do this?

ie: having the following paths:

/general/baz/bro
/general/foo/bar
/general/unknown

I would like to map the first one to a specific handler and all the others to the default handler.

I have tried something like:

r.Methods("GET").PathPrefix("/general").Handler(defaultHandler)
r.Methods("GET").Path("/general/baz/bro").Handler(bazBroHandler)

I expected bazBroHandler to handle the path /general/baz/bro

, and defaultHandler to handle everything else starting with/general

In the end I just realized that I need to invert the order:

r.Methods("GET").Path("/general/baz/bro").Handler(bazBroHandler)
r.Methods("GET").PathPrefix("/general").Handler(defaultHandler)


now everything works!

One way to achieve this is to use MatcherFunc . In MatcherFunc

compare / check the incoming request Path

, that is:



//Default handler
r.MatcherFunc(func(r *http.Request, rm *mux.RouteMatch) bool {
    return r.URL.Path != "/general/baz/bro" && strings.HasPrefix(r.URL.Path, "/general") && r.Method == "GET"
}).Handler(defaultHandler)

//Specific handler
r.Methods("GET").Path("/general/baz/bro").Handler(bazBroHandler)
