golang静态停止index.html重定向

package main

import (
  "log"
  "net/http"
)

func main() {
  fs := http.FileServer(http.Dir("."))
  http.Handle("/", fs)

  log.Println("Listening...")
  http.ListenAndServe(":3000", nil)
}

So I have a index.html file and want server to stop showing it.

The docs for FileServer state that:

As a special case, the returned file server redirects any request ending in "/index.html" to the same path, without the final "index.html".

So /index.html is redirected to /, /foo/bar/index.html is redirected to /foo/bar/.

To avoid this register an additional handler for the special case.

http.HandleFunc("/index.html", func(w http.ResponseWriter, r *http.Request) {
    f, err := os.Open("index.html")
    if err != nil {
        // handle error
        return
    }
    http.ServeContent(w, r, "index.html", time.Now(), f)
})

Please note I'm using ServeContent insead of ServeFile because ServeFile handles /index.html requests the same way as FileServer.

There's no redirection going on, the default file to render when requesting a directory is index.html. The directory listing is a fallback for when this file isn't found, so you can't get a directory listing without removing the index.html file.

If you want a directory listing, you'll have to write it out yourself, which you can then format and style however you choose. The basic structure is very simple if you want to write it directly, take the internal dirList function for example:

w.Header().Set("Content-Type", "text/html; charset=utf-8")
fmt.Fprintf(w, "<pre>
")
for _, d := range dirs {
    name := d.Name()
    if d.IsDir() {
        name += "/"
    }
    url := url.URL{Path: name}
    fmt.Fprintf(w, "<a href=\"%s\">%s</a>
", url.String(), htmlReplacer.Replace(name))
}
fmt.Fprintf(w, "</pre>
")
