I am writing a function in golang to get the value from redis db by passing the key. The value is a list. I am using 'GET' redis command to get the value. But it is giving me error.
You can find below the code,
func GetValue(key string) []string {
var value []string
var err error
value, err = redis.Strings(conn.Do("GET", key))
if err != nil {
log.Fatal(err)
}
fmt.Println(value)
return value
}
func RetrieveValue() {
keyType, _ := conn.Do("TYPE", recentItemKey)
fmt.Println("Type", keyType)
var results []string
results = GetValue(recentItemKey)
for _, val := range results {
fmt.Println(val)
}
}
And the output is here,
Type list

Could anyone help me on this.? Thank you
Use LRANGE to get the elements of a list:
func GetValues(key string) []string {
value, err := redis.Strings(conn.Do("LRANGE", key, 0, -1))
if err != nil {
log.Fatal(err)
}
return value
}
The GET command gets the value of a string key. The GET command does not work on list keys.
