有沒(méi)有辦法ids []int64對(duì)數(shù)據(jù)存儲(chǔ)進(jìn)行查詢？我嘗試了以下無(wú)濟(jì)于事。錯(cuò)誤輸出q := datastore.NewQuery("Category").Filter("Id IN", ids)只為我獲取數(shù)據(jù)存儲(chǔ)中的所有類別for _, id := range ids {    q.Filter("Id =", id)}在icza的回答之后var keys []*datastore.Keyfor _, id := range ids {    keys = append(keys, datastore.NewKey(c, "Category", "", id, nil))}categories := make([]Category, len(keys))err := datastore.GetMulti(c, keys, categories)if err != nil {    return nil, err}
