func save(item interface{}) {
	client, err := elastic.NewClient(elastic.SetSniff(false))
	if err != nil {
		panic(err)
	}
	jitem, err := json.Marshal(item)
	if err != nil {
		panic(err)
	}
	resp, err := client.Index().
		Index("dating_profile").
		Type("zhenai").
		BodyJson(jitem).
		Do(context.Background())
	if err != nil {
		panic(err)
	}
	fmt.Println(resp)
