Have you looked at the gorilla/mux documentation about middlewares?
There are examples there: https://godoc.org/github.com/gorilla/mux
You need to change the validateToken func:
func getTokenMW(srv *server.Server) func(http.Handler) http.Handler {
return func(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
}
}
}
Then:
router.Use(getTokenMW(server))
Or, you can define a struct, put the server pointer in it, and use a
member function of that struct as the middleware.
