我嘗試連接到 REDIS SENTINEL 的代碼。由于我是 golang 新手，想澄清我出了什么問題？REDIS SENTINEL 已配置并正常工作。package mainimport (    "fmt"    "github.com/go-redis/redis")func main() {    rdb:=redis.NewFailoverClient(&redis.FailoverOptions(            MasterName: "mymaster",            SentinelAddrs: "XXX.XXX.XXX.XXX:26379","XXX.XXX.XXX.XXX:26379","XXX.XXX.XXX.XXX:26379",    ))    rdb.Ping()}跑步：$ go run redis.go**# command-line-arguments**>./redif.go:11:12: syntax error: unexpected :, expecting comma or )**
