这是我最后通过将字符串文字（带有时间戳）转换为类型time来解决此问题的方法。
timestamp = "2017-10-09T13:25:00.000Z"tsAfter,err = time.Parse(model.TimeLayout, timestamp)if err != nil { errs = append(errs, err.Error())}log.Printf("GET param [id = %s]", idStr)log.Printf("GET param [after = %s]", tsAfter.String())m := map[string]interface{}{}query := "SELECt id, time, type, val FROM events WHERe id = ? AND time >= ?"iterable := cql.Session.Query(query, idStr, tsAfter).Consistency(gocql.One).Iter()for iterable.MapScan(m) { eventList = append(eventList, model.Event{ ID: m["id"].(string), Time: m["time"].(time.Time), Type: m["type"].(string), Val: m["val"].(float64), }) m = map[string]interface{}{}}
