This article illustrates how the go language implements one of the simplest http file servers. Share with you for your reference. The specific implementation method is as follows:

package main
import (
    "net/http"
)
func main() {
    http.Handle("/", http.FileServer(http.Dir("./")))
    http.ListenAndServe(":8123", nil)
}

I hope this article has been helpful to your programming of Go language.
