[Redis-CentOS7]Redis哈希操作(五)

哈希相当于下面Python代码

{
    "person":{
    "name": "peigy",
    "age": "18",
    }
}

HSET添加哈希

127.0.0.1:6379> HSET website google "www.google.com"
(integer) 1
127.0.0.1:6379> HGET website google
"www.google.com"

删除哈希

127.0.0.1:6379> hdel website google
(integer) 1

获取所有的key value

127.0.0.1:6379> HSET website google "www.google.com"
(integer) 1
127.0.0.1:6379> HSET website baidu "www.baidu.com"
(integer) 1
127.0.0.1:6379> HGETall website
1) "google" #key
2) "www.google.com" #value
3) "baidu"
4) "www.baidu.com"

HMSET一次添加多个键值对

127.0.0.1:6379> HMSET person name xxx age 18 height 180
OK
127.0.0.1:6379> HGETall person
1) "name"
2) "xxx"
3) "age"
4) "18"
5) "height"
6) "180"

分别获取键值

127.0.0.1:6379> hkeys website
1) "google"
2) "baidu"
127.0.0.1:6379> hvals website
1) "www.google.com"
2) "www.baidu.com"

查看key是否存在

127.0.0.1:6379> HEXISTS website google
(integer) 1
127.0.0.1:6379> HEXISTS website sina
(integer) 0

获取总共的键值对

127.0.0.1:6379> HLEN website
(integer) 2
127.0.0.1:6379> HLEN person
(integer) 3
