redigo 怎么监听redis键的过期和删除事件呢?

在文档里也没找到, 偶然发现其实监听主题,然后我这样做 psc := redis.PubSubConn{Conn: red} psc.Subscribe("__keyspace@1__:del") for { switch v := psc.Receive().(type) { case redis.Message: fmt.Printf("%s: message: %s\n", v.Channel, v.Data) case redis.Subscription: fmt.Printf("%s: %s %d\n", v.Channel, v.Kind, v.Count) case error: fmt.Println("error") } }  监听一号库的删除事件,好像也不行啊,?
