文字

SETEX key seconds value

自2.0.0起可用。

時間復雜度: O(1)

設置key為保留字符串valuekey在給定秒數后設置為超時。該命令相當于執行以下命令:

SET mykey value
EXPIRE mykey seconds

SETEX 是原子的,可以通過使用 MULTI / EXEC 塊內的前兩個命令來重現。它作為給定操作序列的一個更快的替代方式提供,因為當 Redis 用作緩存時,此操作非常常見。

seconds無效時返回錯誤。

返回值

簡單字符串回復

例子

redis>  SETEX mykey 10 "Hello" "OK" redis>  TTL mykey (integer) 10 redis>  GET mykey "Hello"
