    Abs:                      jurl.NewBool(true),  // Require the URL to be absolute
    AllowedSchemes:           []string{"https"},   // Only allow scheme https
    NormalizePort:            jurl.NewBool(false), // Remove port if it is the default port for the URL.
    StripFragment:            true,
    StripQuery:               true,                // Remove query string.

if err != nil {
    log.Fatal(err)
