    EXPIREAT key timestamp

    自1.2.0起可用。

    时间复杂度: O(1)

    EXPIREA T与 EXPIRE 具有相同的效果和语义,但不是指定表示TTL(生存时间)的秒数,而是需要绝对的 Unix时间戳(1970年1月1日以来的秒数)。过去的时间戳会立即删除密钥。

    有关该命令的具体语义,请参阅 EXPIRE 的文档。

    背景

    引入 EXPIREAT 是为了将相对超时转换为 AOF 持久模式的绝对超时。当然,它可以直接用来指定给定密钥将在特定时间到期。

    返回值

    整数回复,具体为:

    • 1 如果超时被设置。

    • 0如果key不存在。

    例子

    redis>  SET mykey "Hello" "OK" 

    redis>  EXISTS mykey (integer) 1 

    redis>  EXPIREAT mykey 1293840000 (integer) 1 

    redis>  EXISTS mykey (integer) 0
