I am a beginner for Go. I try to build a static web server in my local computer. Actually, I have been read How do you serve a static html file using a go web server?

My question is, if I have a Home.html. I want to open Home.html when I link localhost:7777.

It's like index.html, but I want to replace index.html with Home.html.

Here is my code:

package main
import (
    "fmt"
    "net/http"
    "log"
)

func helloHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "hello world!")
}
func main() {

    http.HandleFunc("/", helloHandler)
    // 
    err := http.ListenAndServe(":7777", nil)
    if err != nil {
        log.Fatal("ListenAndServe", err)
    } else {
        log.Println("listen 7777")
    }
}

How do I re-write this code?

What keywords for this problem?

The quoted code doesn't serve any static files, so "how do I modify this code to do something completely different" is too broad a question. Can you narrow it down to some particular issue you're having? — Adrian

To serve any static file to an endpoint, you can use http.ServeFile or http.ServeContent if you want more control.

In this case, you can write:

func helloHandler(w http.ResponseWriter, r *http.Request) {
    http.ServeFile(w,r,"Home.html")
}

Be sure to set the name to the path of Home.html. It is possible for the program to not find the file when using a relative path when running from elsewhere.
