I trying to connect redis with go using redigo, redis-server is running.
I want to create a list of strings, append one string , then get all the elements from the server and print them out.
this , what I tried
package main
import (
"fmt"
"github.com/garyburd/redigo/redis"
)
func main() {
c, err := redis.Dial("tcp", ":6379")
check(err)
defer c.Close()
_, err = c.Do("LPUSH", "bars", "foo")
check(err)
n, err := redis.Values(c.Do("LRANGE", "bars", 0, 10))
check(err)
fmt.Println(n)
}
func check(err error) {
if err != nil {
panic(err)
}
}
I get [[102 111 111]] printed instead of foo, it seems that
How can I convert []interface{} (Values return type) to []string ?
I'm not familiar with the package you're using, but the documentation suggests that using redis.Strings() instead of redis.Values() will do what you're after:
Strings is a helper that converts a multi-bulk command reply to a []string. If err is not equal to nil, then Strings returns nil, err. If one if the multi-bulk items is not a bulk value or nil, then Strings returns an error.
