Go语言实现redis的封装及一些使用
最近在学习Golang，所以将学习过程记为笔记，以后翻阅的时候也方便，顺便也给大家做一点分享，希望能坚持下去。
学习与交流：
现在就开始你的Go语言学习之旅吧！人生苦短，let’s Go.
go redis 集合操作--sadd
redis的go语言包，我们使用官方推荐的redigo，https://github.com/garyburd/redigo
安装redigo
$ go get github.com/garyburd/redigo
带密码的redis操作
package main
import (
"log"
"github.com/garyburd/redigo/redis"
)
func main() {
server := "127.0.0.1:6379"
option := redis.DialPassword("123456")
c, err := redis.Dial("tcp", server, option)
if err != nil {
log.Println("connect server failed:", err)
return
}
defer c.Close()
v, err := redis.Int64(c.Do("SADD", "myset", "10.8.37.98"))
if err != nil {
log.Println("SADD failed:", err)
return
}
log.Println("value:", v)
}
批量添加
package main
import (
"log"
"github.com/garyburd/redigo/redis"
)
func main() {
server := "127.0.0.1:6379"
option := redis.DialPassword("123456")
c, err := redis.Dial("tcp", server, option)
if err != nil {
log.Println("connect server failed:", err)
return
}
defer c.Close()
setKey := "myset"
args := []interface{}{setKey}
args = append(args, "10.1")
args = append(args, "10.2")
v, err := redis.Int64(c.Do("SADD", args...))
if err != nil {
log.Println("SADD failed:", err)
return
}
log.Println("value:", v)
}
无密码redis操作
package main
import (
"fmt"
"github.com/gomodule/redigo/redis"
)
func main() {
c, err := redis.Dial("tcp", "127.0.0.1:6379")
if err != nil {
fmt.Println(err)
return
}
defer c.Close()
c.Do("SET", "hello", "world")
s, err := redis.String(c.Do("GET", "hello"))
redis封装包
package redis
import (
"autumn/tools/cfg"
"fmt"
"github.com/gomodule/redigo/redis"
"log"
)
var REDIS redis.Conn
func InitRedis() {
REDIS = redis_connect("default")
}
func CloseRedis() {
REDIS.Close()
}
func redis_connect(project string) redis.Conn {
server := fmt.Sprintf("%s:%s",
cfg.Get("redis", project+".host").String(),
cfg.Get("redis", project+".port").String())
var err error
option := redis.DialPassword(cfg.Get("redis", project+".passwd").String())
c, err := redis.Dial("tcp", server, option)
if err != nil {
log.Fatal("[GIN-MYSQL(" + project + ")] connect to redis error:" + err.Error())
}
log.Println("[GIN-Redis(" + project + ")] connected success")
return c
}
