go操作redis的有序集合(zset)

package mainimport (    "fmt"    "github.com/garyburd/redigo/redis")func main() {    // 连接redis数据库,指定数据库的IP和端口    conn, err := redis.Dial("tcp", "36.99.16.197:6379")    if err != nil {        fmt.Println("Connect to redis error", err)        return        } else {        fmt.Println("Connect to redis ok.")    }    // 函数退出时关闭连接    defer conn.Close()    // 执行一个有序zset插入    _, err = conn.Do("ZADD", "mykey", "INCR", 1, "robot1")    if err != nil {        fmt.Println("redis set failed:", err)    }    // 再执行一个有序zset插入    _, err = conn.Do("ZADD", "mykey", "INCR", 1, "robot2")    if err != nil {        fmt.Println("redis set failed:", err)    }    // 读取指定zset    user_map, err := redis.StringMap(conn.Do("ZRANGE", "mykey", 0, 10, "withscores"))    if err != nil {        fmt.Println("redis get failed:", err)    } else {        fmt.Printf("Get mykey: %v \n", user_map)    }    for user := range user_map {        fmt.Printf("user name: %v %v\n", user, user_map[user])    }}

输出:
Connect to redis ok.
Get mykey: map[robot1:1 robot2:1]
user name: robot1 1
user name: robot2 1
