HGETALL key
自2.0.0起可用。
时间复杂度： O（N）其中 N 是散列的大小。
返回存储在中的哈希的所有字段和值key。在返回的值中，每个字段名称的后面跟着它的值，所以回复的长度是散列大小的两倍。
返回值
数组回复：存储在散列中的字段及其值的列表，或key不存在时的空列表。
例子
redis> HSET myhash field1 "Hello" (integer) 1
redis> HSET myhash field2 "World" (integer) 1
redis> HGETALL myhash 1) "field1" 2) "Hello" 3) "field2" 4) "World"
