redis五种数据结构

  • 字符串 (String): 使用 SET key value 命令设置字符串类型的键值对。

    例如：SET mykey "Hello"

  • 列表 (List): 使用 LPUSH key value1 value2 或 RPUSH key value1 value2

命令在列表左侧或右侧添加元素。

例如：LPUSH mylist "World"

  • 集合 (Set): 使用 SADD key member1 member2 命令向集合添加成员。

例如：SADD myset "one"

  • 哈希 (Hash): 使用 HSET key field1 value1 field2 value2 命令为哈希表设置字段和值。

例如：HSET myhash field1 "value1"

  • 有序集合 (Sorted Set): 使用 ZADD key score1 member1 score2 member2 命令向有序集合添加成员，每个成员都有一个分数。

例如：ZADD myzset 1 "member1"
