not very nice way to iterate over a struct using reflect in golang

reflect_struct.go

// ...
type Config struct {
  Db    Conf `json:"db"`
  Relay Conf `json:"relay"`
  Redis Conf `json:"redis"`
}
type Conf struct {
  Path   string `json:"path"`
  Port   string `json:"port"`
  Server string `json:"server"`
}

// ...
typ := reflect.TypeOf(co)
val := reflect.ValueOf(co)

for i := 0; i < val.NumField(); i++ {
  fn := typ.Field(i).Name // Db, Redis ...

  log.Debug(fn)
    for j := 0; j < val.FieldByName(fn).NumField(); j++ {
      ttyp, _  := typ.FieldByName(fn)

      log.Debug( ttyp.Type.Field(j).Name) // Path, Port ..
      log.Debug( val.FieldByName(fn).Field(j).String()) // values
  }
}
// ...
