How do I get and set data from redis in Go?

Question

var rdb *redis.Client
var ctx = context.Background()


    rdb = redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "", // no password set
        DB:       0,  // use default DB
    })

// set for 24 hours
err := rdb.Set(ctx, topics, data, 86400).Err()

// err is nil

val, err := rdb.Get(ctx, topics).Result()

// val is empty

when i check redis manually there's nothing there.

Answer 1

cannot use integers for time

24 * time.Hour works but 86400 does not.
