goredis操作redis,[https://github.com/go-redis/redis][https_github.com_go-redis_redis]

安装：

go get github.com/go-redis/redis/v7

go存放二维数组到redis

package main

    					DB:                 0,
    				})
    
    	pong, err := client.Ping().Result()//心跳
    	fmt.Println(pong, err)
    
    	//设置60秒过期的key
    	setResultExpire  := client.Set("hello","world! "+time.Now().Format("2006-01-02 15:04:05"),60*time.Second)
    	setResultForever := client.Set("notExpire","This key not expire !",0)//设置不过期的key
    
    	fmt.Println(setResultExpire)

    	getValue,_ := client.Get("hello").Result()//获取key的结果
    	fmt.Println(getValue)

    	//计数
    	incrStatus,_ := client.Incr("incrKey").Result()
    	fmt.Println(incrStatus)
    
    	//把info二维数组存到redis里面
    	info := [][]string{
       {"ID","姓名", "密码","加入时间"},{"1","DennyYang", "123456","2020-01-01 01:02:03"}}
    	//info数组转换成json
    	inforByte,infoError := json.Marshal(info)

    		if infoErrorStatus!=nil{
    			fmt.Println("设置info出错：",infoErrorStatus)
    		}else{

    		}
    	}
    
    	getInfo,getinfoErr := client.Get("info").Result()
    	if getinfoErr != nil{
    		fmt.Println("没有获取到数据",getinfoErr)
    	}else{
    		//获取到json字符串,反序列化,原来是二维数组的,反序列化的时候也要用二维数组接收
    		var getInfoResult[][]string
    		unmarsha1Err := json.Unmarshal([]byte(getInfo),&getInfoResult)
    
    		if unmarsha1Err !=nil{
    			fmt.Println("反序列化失败:",unmarsha1Err)
    		}else{
    			//迭代数据
    			for key,value := range getInfoResult{

    		}
    
    	}
