// Each is a utility function to iterate over all hits. It saves you from // checking for nil values. Notice that Each will ignore errors in // serializing JSON and hits with empty/nil _source will get an empty // value func (r *SearchResult) Each(typ reflect.Type) []interface{} { if r.Hits == nil || r.Hits.Hits == nil || len(r.Hits.Hits) == 0 { return nil } slice := make([]interface{}, 0, len(r.Hits.Hits)) for _, hit := range r.Hits.Hits { v := reflect.New(typ).Elem() if hit.Source == nil { slice = append(slice, v.Interface()) continue } //if json.Unmarshal err，no err message，no data and Not easy to find //if json.Unmarshal err，no err message，no data and Not easy to find //if json.Unmarshal err，no err message，no data and Not easy to find //if json.Unmarshal err，no err message，no data and Not easy to find //if json.Unmarshal err，no err message，no data and Not easy to find //if json.Unmarshal err，no err message，no data and Not easy to find if err := json.Unmarshal(hit.Source, v.Addr().Interface()); err == nil { slice = append(slice, v.Interface()) } } return slice }
