使用go操作redis的有序集合(zset)_Golang_

 package main import ( "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]) } } 

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

 s := zset.New() // add data s.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 data s.Set(44, 1001, "test1") // get rank by id rank, score, extra := s.GetRank(1004, false) // get data by rank id, score, extra := s.GetDataByRank(0, true) // get data by id dat, ok := s.GetData(1001) // delete data by id s.Delete(1001)
