My simple web application was working fine, except for the part that it was showing directory listings, which I'd like to avoid.
After searching, came to this solution https://groups.google.com/forum/#!msg/golang-nuts/bStLPdIVM6w/hidTJgDZpHcJ using a virtual file-system. My app has the following structure ~/go | |___ go binary (or go source files) | |___ static/css, static/js, static/images | |___ html/ where index.html, kit1.html, other html files are This was working fine, but a user could point to http://mysite/static and get a directory listing which I’d like to prevent. Tried to adapt my code to that virtual filesystem solution above: func main() { //fs := http.FileServer(http.Dir("static/")) (old, working) http.HandleFunc("/", indexHandler) http.HandleFunc("/kit1", indexHandler) fs := justFilesFilesystem{http.Dir("")} http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(fs))) log.Fatal(http.ListenAndServe(":8090", http.FileServer(fs))) // second parameter was nil before } 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 } The handler begins with func indexHandler(w http.ResponseWriter, r *http.Request) { path, err := filepath.Abs(filepath.Dir(os.Args[0])) // error checking surpressed switch r.Method { case "GET": f := urlToFile(r.URL.Path) fmt.Println("f: ", f) if f == "" { f = "index.html" } fmt.Println("f_after: ", f) http.ServeFile(w, r, "html/"+f) Although it seems to load around 150Kb, it shows a blank page having just <pre> </pre> If `index.html` is copied from html/index.html to /home/lupe/go/ the server renders it. The function `indexHandler` doesn’t seem to be called whenever `/`, `index.html` or `/kit1.html` is chosen, as the `fmt.Println` function doesn't print anything on the console. Without changing the html/ and static/ files locations, what changes should I do to the code? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
