在线状态库里没有、会话也判定不了 —— session 的 TTL 是 7 天且每次请求续期, 「有会话」只说明这人一周内来过。新开一个 Redis sorted set(auth/presence.ts) 记最后活动时间,5 分钟内有活动算在线。 写入全搭在已有的 pipeline 上,不多一趟往返:登录、每个带鉴权请求的续期、 以及 touchSession —— 只挂着 WebSocket 不发请求的人靠最后这条,sweepSessions 每 60 秒一轮,所以窗口取 5 分钟,明显大于那个间隔。登出、改密码、禁用账号 会立刻把人摘掉;过期成员在后台读列表时顺手清理(整个 key 不能设 TTL, ZADD 不重置 key 的 TTL,到期会把还在线的人一起抹掉)。 排序 orderBy=-online 先捞在线 id,SQL 里 case when 分两档,档内继续按 最近登录排;没人在线时那个 case 恒等于 1,直接省掉。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017xu912Rv5JUUuy6MqMcQW2
