Как получить сообщение test Message?

package main

import (
	"fmt"
	"github.com/go-redis/redis"
)


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

func handlSub(client redis.Client){
	sub := client.Subscribe("1_message")
	for{
		iface, err := sub.Receive()
		if err != nil {
			fmt.Println(err)
		}

		// Should be *Subscription, but others are possible if other actions have been
		// taken on sub since it was created.
		switch iface.(type) {
		case *redis.Subscription:
			fmt.Println("sub")
		case *redis.Message:
			fmt.Println(iface)
		case *redis.Pong:
			fmt.Println("pong")
		default:
			fmt.Println("err")
		}
	}
}
