Disable directory listing with ServeFiles about httprouter

[gadelkareem]

There is a config option for this DirectoryIndex = False

[junxie6]

I have added a middleware to disable directory listing:

package main

import (
        "log"
        "net/http"
        "strings"
)

import (
        "github.com/julienschmidt/httprouter"
)

const (
        gStaticDir = "static"
)

var (
        gMux *httprouter.Router
)

func main() {
        gMux = httprouter.New()

        // Serving the static files - use this if you would like to work with some middlewares.
        // NOTE: FileServer calls path.Clean() to clean up path.
        gMux.Handler("GET", "/"+gStaticDir+"/*filepath", NoDirListingHandler(http.StripPrefix("/"+gStaticDir+"/", http.FileServer(http.Dir(gStaticDir)))))

        srv := &http.Server{
                Handler: gMux,
                Addr:    ":8080",
        }

        if err := srv.ListenAndServe(); err != nil {
                log.Fatal("http.ListenAndServe: ", err)
        }
}

func NoDirListingHandler(h http.Handler) http.Handler {
        return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
                if strings.HasSuffix(r.URL.Path, "/") {
                        http.NotFound(w, r)
                        return
                }
                h.ServeHTTP(w, r)
        })
}

Hi, I solved this problem through http://stackoverflow.com/questions/13302020/rendering-css-in-a-go-web-application this answer. I'm a beginner and probably couldn't patch it for now. I did define funcs as in the answer.

type justFilesFilesystem struct {
fs http.FileSystem
}

func (fs justFilesFilesystem) Open(name string) (http.File, error) {
f, err := fs.fs.Open(name)
if err != nil {
return nil, err
}
return neuteredReaddirFile{f}, nil
}

type neuteredReaddirFile struct {
http.File
}

func (f neuteredReaddirFile) Readdir(count int) ([]os.FileInfo, error) {
return nil, nil
}

and before http.ListenAndServe

fs := justFilesFilesystem{http.Dir("/path/to/")}

router.Handler("GET", "/static/*filepath", http.StripPrefix("/static", http.FileServer(fs)))

It works properly, no directory listing, and access js, cs etc. files.

ServeFiles just wraps http.FileServer. I don't think it has a way to disable directory listing.
