Get full URL from http request in go

fullURL.go

func fullURL(r *http.Request, overridePath ...string) string {
	scheme := "http"
	if r.TLS != nil {
		scheme = "https"
	}
	if len(overridePath) != 0 {
		return fmt.Sprintf("%s://%s%s", scheme, r.Host, overridePath[0])
	}
	return fmt.Sprintf("%s://%s%s?%s#%s", scheme, r.Host, r.URL.Path, r.URL.RawQuery, r.URL.Fragment)
}

Is there already a package which provides that?

@guettli Let me know if you find one. I can post the link here if anybody else finds this.

This version handles empty query and fragment

func fullURL(r *http.Request) string {
	builder := strings.Builder{}

	if r.TLS != nil {
		builder.WriteString("https://")
	} else {
		builder.WriteString("http://")
	}

	builder.WriteString(r.Host)
	builder.WriteString(r.URL.Path)

	if r.URL.RawQuery != "" {
		builder.WriteString("?" + r.URL.RawQuery)
	}

	if r.URL.Fragment != "" {
		builder.WriteString("#" + r.URL.Fragment)
	}

	return builder.String()
}
