Golang提供html文件

I have some html files in folder /html (for example main.html,page1.html, page2.html,etc ). And I serve it, using next Go code

r := mux.NewRouter()
r.PathPrefix("/").Handler(http.StripPrefix("/", http.FileServer(http.Dir(htmlDir))))

So if I open address http://127.0.0.1/page1.html, then page1.html will be shown( it is what I need). But I also want to bind address http://127.0.0.1/ to main.html. How can I do it?

I can rename main.html to index.html, but I think it is not true way.

    You could additionally add a HandlerFunc to handle that:

    r := mux.NewRouter()
    r.HandleFunc("/", homeHandler)
    r.PathPrefix("/").Handler(http.StripPrefix("/", http.FileServer(http.Dir(htmlDir))))
    

    In the homeHandler you serve the file you want to serve:

    func homeHandler(w http.ResponseWriter, r *http.Request) {
        http.ServeFile(w, r, fmt.Sprintf("./%s/index.htm", htmlDir))
    }
    

    There might be other options...
