func FindNearTruck(ctx context.Context, long, lat float64, r float64, sort string) []string {
    //
    q := &redis.GeoSearchQuery{
        Member:    "FROMLONLAT",
        Longitude: long,
        Latitude:  lat,
        //Radius:     r,
        //RadiusUnit: "km",
        Sort:      sort,
        BoxWidth:  200,
        BoxHeight: 200,
        BoxUnit:   "km",
    }
    log.WithField("q", q).Info("=================q")
    //result := make([]string, 0)
    result, err := db.RDB.GeoSearch(ctx,"geohash", q).Result()
    if err != nil {
        log.Fatal(err)
        return nil
