golang-redis之sorted set类型简单操作

1：安装redigo

go get github.com/garyburd/redigo/redis

2：引用redigo

import （    "github.com/garyburd/redigo/redis")

3：连接Redis

c, err := redis.Dial("tcp", "192.168.2.225:6379")if err != nil {    fmt.Println("connect to redis err", err.Error())    return}defer c.Close()

4：命令

n,err := c.Do("zadd","key","score","member")  //写result,err := redis.Values(c.Do("zrange","key",0,-1))//读

5：sorted set简单操作

zadd(key, score1,member1,...scoreN,memberN) 向有序结合添加（更新）一个或多个成员zcard(key)：获取有序集合的成员zcount(key,start,end):计算指定区间的成员数zincrby(key,increment,member):成员member增加incrementzinterstore(dst,numkey,src1,src2..srcN)：求交集，并将结果存储新的结合zlexcount(key,start,end):计算字典区间成员数(分数都相同，按照字典排序)zrange(key,start,end):获取索引区间的成员zrangebylex (key,start,end):通过字典区间返回区间内有序集合成员zrangebyscore(key,start,end):通过分数返回区间内的有序集合zrank (key,member):返回有序结合的索引zrem(key,members1...membersN):删除一个或多个成员zremrangebylex(key,start,end):移除集合中给定字典区间的成员zremrangebyrank(key,start,end):移除有序集合中给定的排名区间的所有成员zremrangebyscore(key,start,end)：移除给定分数区间的所有元素zrevange(key,start,end):通过索引，分数由高到低，返回指定区域的元素zrevrangebyscore(key,member)：分数由高向低返回指定区间的成员数zrevrank(key,member):分数从小到大，返回指定成员的排名zscore(key,member):返回有序集中，成员的分数值zunionstore(dst,numkeys,key1...keyN):返回给定的一个或多个集合的并集，并存储在新的集合中zscan(key,cursor):迭代有序结合中的元素（包括元素成员和元素分值）
