	if err!=nil{
		fmt.Println("redis.Dial err=",err)
		return
	}
	defer conn.Close()   //延迟关闭

	//2.通过go向redis写入数据hset map
	_,err=conn.Do("HMSet","user002","name","孙悟空","age",500)
	if err!=nil{
		fmt.Println("hset err=",err)
		return

	//_,err=conn.Do("HSet","user001","age",40)
	//if err!=nil{
	//	fmt.Println("hset err=",err)
	//	return
	//}


	//3.通过go向redis读取数据string[key-val]
	//redis.Strings--->这里重点是redis.Strings---是复数“Strings”
	r,err:=redis.Strings(conn.Do("HMGet","user002","name","age"))

	//r,err:=redis.Int(conn.Do("Get","age"))
	if err!=nil{
		fmt.Println("hget err=",err)
		return
	}


	for i,v:=range r{
		fmt.Printf("r[%d]=%s\n",i,v)
	}


	//r1,err:=redis.Int(conn.Do("HGet","user001","age"))
	//
	r,err:=redis.Int(conn.Do("Get","age"))
	//if err!=nil{
	//	fmt.Println("hget err=",err)
	//	return
	//}

	/*
	1.因为返回r是interfce{},name对应的值是string，因此我们
	需要转换nameString,redis.String()
	*/

	//fmt.Printf("操作ok:r=%v r2=%v\n",r,r1)    //查询结果：操作ok:tom and jerry
