# Go-Redis（二）gopkg-redis基本操作 #

gopkg-redis也是一个操作redis的go客户端

安装

go get gopkg.in/redis.v5

## 基本使用 ##

不得不说，go比Java简洁多了

### 连接redis ###

// 连接redis
    func ConnectToRedis() *redis.Client{
        
    	client := redis.NewClient(&redis.Options{
        
    		Addr: "localhost:6379",
    		Password: "123456",
    		DB: 0,
    	})
    	_,err := client.Ping().Result()
    	if err != nil{
        
    		fmt.Println("连接失败,",err)
    	}
    	return client
    }

### 数据结构操作 ###

gopkg-redis提供的API我个人觉得要比redigo更加方便些，redigo类似于指定cli指令。

参考了这篇博客对API的整理，辛苦这位大佬：

// -------------------------
    	// ------- string操作 -------
    	// -------------------------
    	// set k v expire time
    	client.Set("gopkg","redis",3 * time.Second)
    	// get k
    	var v1 string
    	client.Get("gopkg").Scan(&v1)
    	fmt.Println("get gopkg：",v1)

#### list ####

    	client.LSet("list2",0,"list21")
    	client.LSet("list2",1,"list22")
    	// lpush
    	client.LPushX("list2","list23")
    	client.LPushX("list2","list26")
    	client.LPushX("list2","list25")
    	// rpush
    	client.LPush("list2","list27")
    	client.LPush("list2","list24")
    	// lpop
    	res1,_ := client.LPop("list2").Result()
    	fmt.Println("list lpop: ", res1)
    	// rpop
    	res2,_ := client.RPop("list2").Result()
    	fmt.Println("list rpop: ", res2)
    	// lrange list start end
    	l,e:= client.LRange("list2",0,3).Result()
    	if e != nil{
        
    		panic(e)
    	}
    	for _,val := range l{
        
    		fmt.Println(val," ")
    	}

#### set和hash ####
