How can I remove index.html
from my url string eg.localhost:8000/index.html
package main
import (
"net/http"
"io/ioutil"
)
func main() {
http.Handle("/", new(MyHandler))
http.ListenAndServe(":8000", nil)
}
type MyHandler struct {
http.Handler
}
func (this *MyHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
path := "public" + req.URL.Path
data, err := ioutil.ReadFile(string(path))
if err == nil {
w.Write(data)
} else {
w.WriteHeader(404)
w.Write([]byte("404 - " + http.StatusText(404)))
}
}

Add a condition to serve index.html if the URL path is empty:
path := "public"
if req.URL.Path == "/" {
path += "/index.html"
} else {
path += req.URL.Path
}
Also, it would be nice to use it net/http.ServeFile
to manually write data to the output stream (see net/http#ServeContent
to see why it's a good idea).
It's also worth noting that there is a built-in handler for serving files .
