推送通知:Web Push(网页 / PWA)+ 桌面原生通知
页面 / PWA 关闭、或桌面窗口非前台时,收到文件、消息、传输完成 / 失败以系统通知提醒。
判定统一为「页面打开走应用内提示,否则系统通知」,三端各自落地;网页端的判定直接复用
Hub.SendTo 的投递结果,零额外状态。
- Web Push(VAPID,账号无关):服务端 internal/push.Sender 在事件未经 SSE 投递到目标
设备时(即该设备页面已关)发推送,文案按订阅 locale 在服务端渲染(中简 / 中繁 / 英)、
404 / 410 自动清理死订阅;新增 push_subscriptions 表(含 locale,主键为 endpoint 的
SHA-256 以幂等 upsert)+ /api/push/{vapid-key, subscribe POST/DELETE} 端点
- 事件挂接:transfer:incoming / message(离线返 202,文本随推送送达)/ transfer:state
DONE|FAILED,均未投递才推
- 配置 CDROP_VAPID_PUBLIC_KEY / CDROP_VAPID_PRIVATE_KEY(半对即拒启动,都空则推送惰性
关闭)+ just vapid-keygen 生成工具(cmd/vapidgen)
- 前端:service worker 加 push / notificationclick(仍不拦截 /api 与导航);net/push.ts
订阅管理 + push store slice + 设置页「推送通知」面板(仅浏览器 / PWA);登录后 resyncPush
把既有订阅重新登记到当前用户,换用户 / endpoint 轮换 / 切换语言皆自愈
- 桌面原生通知:platform/notify_{darwin,windows,other}.go + notify_darwin.m,仅窗口非
前台时弹原生通知(macOS UNUserNotificationCenter,未签名时安全空操作、待签名后显示;
Windows go-toast 即用);app.go ShowNotification 绑定,前端 notifyNativeIfBackground
复用 hub 事件分发 + 客户端本地化
- 文档:README / .env.example / compose 模板补 CDROP_VAPID_* 配置
注:sqlc v1.31.1 对 query 文件里的多字节字符会错位偏移、生成损坏 SQL,故 query 注释保持纯
ASCII(文件内留有警示)。
