+# Push Server (开发用)
+
+这是一个用于本地开发与调试的轻量 Node.js 推送后端（mock）。
+
+功能：
+- 注册/更新设备：`POST /api/v1/push/register` { cid, user_id, platform }
+- 注销设备：`POST /api/v1/push/unregister` { cid | user_id }
+- 列出设备：`GET /api/v1/push/devices?user_id=...&active=true|false`
+- 发送推送（模拟）：`POST /api/v1/push/send` { cids:[], user_id, notification, payload }
+
+如果你有真实的推送服务端 API，可以设置环境变量 `PUSH_PROXY_URL`（和可选的 `PUSH_PROXY_TOKEN`），服务器会将 `/api/v1/push/send` 请求代理到该 URL。
+
+快速使用：
+
+```bash
+cd server
+npm install
+npm start
+```
+
+默认监听端口：`7301`，可通过 `PORT` 环境变量修改。
+
+设备存储在 `server/data/push_devices.json`，用于本地持久化。
