登录挡板只拦新登录,已登录的超限会话(如 pro 已连 5 台)永远不被提示 → 限制形同虚设。
补服务端连接卡点:超限账户连接直接拒,兜住已登录设备(下次一连即被拦,无需重登)。
服务端:
- Entitlement 加 MaxDevices(EntitlementForUser 查 p.max_devices;free 默认 1)
- NodeStore.CountActiveDevices(近 30d 活跃)+ SQLNodeStore/mock 实现
- ConnectNode:activeCount > MaxDevices → 403 {code:DEVICE_LIMIT_EXCEEDED, max_devices}
客户端:
- ConnectApiException 解析 code/max_devices(结构化错误体)
- _connect 遇 DEVICE_LIMIT_EXCEEDED → 置 deviceLimitProvider → 顶层路由弹「移除设备」页
(设备列表走 devicesProvider),移除到上限内自动放行
后端 go test(store/nodes/httpapi/devices)全过;前端 analyze 干净 + 66 测试过。
