EXPIREAT key timestamp

自1.2.0起可用。

时间严重年夜度: O(1)

EXPIREA T与 EXPIRE 具有类似的效果和语义,但不是指定体现TTL(生计时间)的秒数,而是须要相对的 Unix时间戳(1970年1月1日以来的秒数)。之前的时间戳会急速删除密钥。

有关该敕令的详细语义,请参阅 EXPIRE 的文档。

配景

华夏棋牌引入 EXPIREAT 是为了将相对超时转换为 AOF 耐久形式的相对超时。虽然,它可以直接用来指定给定密钥将在特准时间到期。

前往值

整数回复,详细为:

  • 1 假定超时被设置。

  • 0假定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
