无法在Go Gorilla服务器中提供静态文件

Question

I am playing with a small toy server to learn Go web programming.

My project directory structure has the following public directory:

public\
  | style.css

The permissions on public and style.css are r-x and r-- for everyone.

In main.go, I have the following lines:

router := mux.NewRouter()
router.Handle("/static/",
  http.StripPrefix("/static/", http.FileServer(http.Dir("public"))))
log.Fatal(http.ListenAndServe(":3001", router))

Every time I call http://localhost:3001/static/style.css the server returns a 404.

I have tried all combinations of leading and trailing slashes in the paths, but none make any difference.

I am running Go v1.5.3 on Ubuntu 15.10 (x64).

Here's an example of how you can serve any requests to a file in /static/ from a folder called public.

router := mux.NewRouter()
//router.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.Dir("public"))))
router.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir("public/"))))
log.Fatal(http.ListenAndServe(":3001", router))
