+### 功能
+- `POST /api/crawl/run_action`：服务端调用扩展 action，返回结果，并按 `stage` 自动入库
+- **定时任务写死配置**：`config/cron_tasks.js`（不走数据库）
+
+### 运行
+1. 安装依赖
+
+```bash
+cd server
+npm install
+```
+
+2. 配置环境变量
+
+```bash
+copy .env.example .env
+```
+
+3. 初始化/更新表结构
+
+```bash
+node scripts/db_sync.js
+```
+
+4. 启动
+
+```bash
+node app.js
+```
+
+### 定时任务
+编辑 `config/cron_tasks.js` 的 `cron_task_list`，重启服务即可生效。
+
+### 落库表
+- `crawl_run_record`：所有 action 调用的原始请求/响应
+- `amazon_product`：`stage=detail` 详情
+- `amazon_search_item`：`stage=list` 列表 item
+- `amazon_review`：`stage=reviews` 评论
