I am redigo to connect from Go to a redis database. How can I convert a type of []interface {}{[]byte{} []byte{}}
to a set of strings? In this case I'd like to get the two strings Hello
and World
.
package main
import (
"fmt"
"github.com/garyburd/redigo/redis"
)
func main() {
c, err := redis.Dial("tcp", ":6379")
defer c.Close()
if err != nil {
fmt.Println(err)
}
c.Send("SADD", "myset", "Hello")
c.Send("SADD", "myset", "World")
c.Flush()
c.Receive()
c.Receive()
err = c.Send("SMEMBERS", "myset")
if err != nil {
fmt.Println(err)
}
c.Flush()
// both give the same return value!?!?
// reply, err := c.Receive()
reply, err := redis.MultiBulk(c.Receive())
if err != nil {
fmt.Println(err)
}
fmt.Printf("%#v
", reply)
// $ go run main.go
// []interface {}{[]byte{0x57, 0x6f, 0x72, 0x6c, 0x64}, []byte{0x48, 0x65, 0x6c, 0x6c, 0x6f}}
// How do I get 'Hello' and 'World' from this data?
}
