feat(通知): 系统级 Webhook 通知子系统(事件目录 + 可插拔适配器 + 防刷屏)
平台此前出了问题只能靠人盯页面。现在各组件统一走 `notifier.notify(事件, **字段)`, 推到企业微信 / 自建服务;**所有可通知点都登记进事件目录,默认全关,用户按 webhook 勾选**。 ## 架构(`core/notifier.py` + `core/notify_events.py`) 业务线程调 `notify()` → 只做内存操作(读配置快照/匹配订阅/入队)→ 返回; 后台 1 个 dispatcher(聚合 + 每 hook 限流 + 折叠摘要)+ 3 个 sender(真实 HTTP、退避重试) 负责真正发出去。硬约束:**notify 零 DB、零 HTTP、零阻塞、异常不冒泡**——所以任务线程里 可以直接调(不用 app_context、不用 try/except),但**必须放在所有 `with self._lock` 之外**。 - **事件目录 36 条**(任务批次/单设备/设备/Worker/业务/安装/系统/AI),支持 `task.*` 通配订阅; 语义分工避免重复告警:`worker.*` 是单次尝试级,`task.device.success/failed` 是唯一权威结论。 - **适配器可插拔**:`wecom`(markdown,按 4096 **字节**截断、超限不截半个汉字)+ `json`(模板占位符,替换值按 JSON 转义,保存前干跑校验);钉钉/飞书留了插槽(前端置灰)。 - **防打爆四层**:聚合窗口(默认 30s,同批次合并成一条并带样本)→ 令牌桶限流(默认 18/分, 对齐企微硬限 20)→ 被限流的**折叠成摘要不丢弃** → 有界队列背压。取舍:失败通知最多延迟 一个窗口,换来群不被刷屏。 ## 安全与存储 - 配置只落 `app_meta.notify_webhooks` 一个键(**不建表** → 不涉及备份覆盖红线)。 - URL 本身就是凭据(企微 `?key=`)→ 接口回显/发送记录/日志一律 `mask_url()/scrub()`; 编辑时留空即不修改;secret 永不回显。DATA_MODEL 的明文凭据告警补上了这一条。 - 发送记录:内存环形缓冲 200 条(重启清空)+ 独立 `logs/notify.log`。 ## 接入点(每个都放在锁外、不改 return 顺序) task_manager(批次开始/结束用新增的 `_BatchTracker` 统一在 finally 计数、单设备成功/失败/ 离线/重试/停止/抢占/归还/cron 停止)、device_worker 心跳看门狗、generic 任务选择器连续失效、 apk 安装开始/完成、设备上下线(**状态沿检测**,只报新变化)、备份导出/恢复、经验巡检、 用户登录、服务启停。 ## 前端 系统 Tab 新增「通知 / Webhook」子分栏:多条 webhook 列表(URL 打码)+ 编辑弹窗(格式/URL/ 密钥/事件勾选树带 ★建议/聚合/限流/自定义模板/预览)+ 发送测试 + 发送记录。 ## 自测 - 进程内逻辑 10 组断言全绿:聚合合并、限流+折叠、无配置/全局关静默丢弃、未知事件、 内部异常不外泄、JSON 转义(标题含引号换行仍合法)、URL/异常消息脱敏、配置校验。 - 端到端(假 webhook 接收端)17 项断言全绿:真实事件投递(user.login / task.batch.no_device)、 企微请求体形状、**HTTP 200 + errcode 93000 判为失败**、500 重试 3 次、记录里 URL 打码。 - 韧性:webhook 指向黑洞地址时登录耗时 100~114ms(基线 107~133ms,**异步隔离生效**); 配置写成坏 JSON 服务照常启动、通知静默不发、日志有 error(服务端实测后已复原)。 - 页面:系统 → 通知 面板/弹窗/36 个事件复选框/预览全部正常,无 JS 报错。 - 自测数据已清理(webhook、自建任务、写坏又复原的配置键)。 文档:新增 doc/NOTIFY.md(事件表/配置/格式约束/防刷屏/加事件三步骤/排障)并登记进 doc/README; API.md §2.11;DATA_MODEL 的 app_meta 键表与明文凭据告警;ARCHITECTURE 线程表/分层/扩展点; 根 README 功能索引与日志表。
