* 1. 异常, 返回 ("",error) 2. 正常, 但key不存在或者field不存在, 返回 ("",redisCluster.ErrNil) 3. 正常, 且key存在, filed存在, 返回 (string, nil)

func (*RedisClusterClient) HMGet added in v1.6.7 

func (r *RedisClusterClient) HMGet(key string, fields []string) ([]interface{}, error)

*

  1. 异常, 返回 (nil, error)
  2. 正常, 返回 ([]interface{}, nil), 其中slice里的值顺序与fields一一对应, 对于不存在的field, 对应值为nil 例如: HMGet("key", []string{"field1","field2","field3"}) 返回值: []interface{}{ "value1", //field1的值 nil, //field2不存在 "value3" //field3的值 },nil 备注: 若key不存在, slice里的所有值都为nil

func (r *RedisClusterClient) HScan(key string, count int64) (map[string]string, error)

* 1. 若异常, 返回 (nil, error) 2. 若正常, 返回 (map[string]string, nil)

Notice: 这个函数并不能严格的限制返回count个，简单测试看起来主要和redis用的存储结构有关。 

Hmap redis在存储的时候如果数据比较少（看文章是512）会使用ziplist，测试了下，在ziplist存储的状态下，会都返回，count不生效
如果数据超过512之后会使用hmap来存储，这时基本就是准确的了。所以这个函数只能保证返回 >= count
