我就废话不多说了，大家还是直接看代码吧~
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])
}
}
输出：
connect to redis ok. get mykey: map[robot1:1 robot2:1] user name: robot1 1 user 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
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 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)
