简介 Go语言开发redis封装及简单使用详解_Golang_

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 }
