用go来驱动redis 存一个 key-value 键值对到redis里，其中value是一个json数组

package main

import (
    "encoding/json"
    "fmt"
    "github.com/garyburd/redigo/redis"
)

type RewardInfo struct {
    Type      uint32 `json:Type`
    Uin       uint64 `json:Uin`
    OrderId   string `json:OrderId`
    Username  string `json:Username`
    Desc      string `json:Desc`
    Cmoney    uint64 `json:Cmoney`
    ScriptId  uint32 `json:ScriptId`
    AuthorUin uint64 `json:AuthorUin`
}

func main() {
    c, err := redis.Dial("tcp", "127.0.0.1:6379")
    if err != nil {
        fmt.Println("Connect to redis error", err)
        return
    }
    defer c.Close()

    var tmp_data []*RewardInfo
    for i := 0; i < 10; i++ {

        })
    }
    data, _ := json.Marshal(tmp_data)
    _, err = c.Do("SET", "script_reward_01", data, "EX", 86400)
    if err != nil {
        fmt.Println(err)
    }
    t_data, err := redis.Bytes(c.Do("GET", "script_reward_01"))

    var show_data []*RewardInfo
    err = json.Unmarshal(t_data, &show_data)
    if err != nil {
        fmt.Println(err)
    }
    //fmt.Println(fmt.Sprintf("%+v", show_data))

    for _, v := range show_data {
        fmt.Println(fmt.Sprintf("%+v", *v))
    }
}
