Loop over map

 
func main() {
	// Allocate memory for the map
	var myMap = make(map[int]string)
	myMap[0] = "test"
	myMap[2] = "sample"
	myMap[1] = "Golang is Fun!"
	
	// Iterate over all keys
	for key, val := range myMap {
		fmt.Printf("Key: %d, Value: %s\n", key, val)
	}
}

Save Hash

Get Hash Key

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

	err := client.HMSet("hashkey", map[string]interface{}{
		"field1": "value1",
		"field2": "value2",
	}).Err()
	if err != nil {
		panic(err)
	}

	vals, err := client.HMGet("hashkey", "field1", "field2").Result()
	if err != nil {
		panic(err)
	}

	for _, v := range vals {
		fmt.Println(v)
	}
