我就废话不多说了，大家还是直接看代码吧~

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 1user name: robot2 1

补充：Redis中zset的golang实现

zset

初衷是在不用Redis的前提下实现排行榜

项目地址https://github.com/liyiheng/zset

Installation

go get -u github.com/liyiheng/zset

Usage

Removed RWLock in the SortedSet.

Just implement it yourself if you need.

s := zset.New()// add datas.Set(66, 1001, "test1")s.Set(77, 1002, "test2")s.Set(88, 1003, "test3")s.Set(100, 1004, "liyiheng")s.Set(99, 1005, "test4")s.Set(44, 1006, "test5")// update datas.Set(44, 1001, "test1")// get rank by idrank, score, extra := s.GetRank(1004, false)// get data by rankid, score, extra := s.GetDataByRank(0, true)// get data by iddat, ok := s.GetData(1001)// delete data by ids.Delete(1001)
