Memcached delete 命令用于删除已存在的 key(键)

语法:

delete key [noreply]
  • key : 键值对 key-value 结构中的 key,用于查找缓存值
  • noreply: 可选, 该参数告知服务器不需要返回数据

删除成功时返回 DELETED

范例

我们先设置 site 的值为 tech.souyunku.com ,存活时间 1000 秒,然后使用 delete 命令删除

flush_all
OK
set site 0 1000 11
tech.souyunku.com
STORED
get site
VALUE site 0 11
tech.souyunku.com
END
delete site
DELETED
get site
END

删除一个不存在的键(key) 会返回 NOT_FOUND key不存在信息

flush_all
OK
delete site
NOT_FOUND
