+# 期货K线接口修复报告
+
+## 问题描述
+
+期货K线接口 `/v1/futures/klines/{symbol}` 返回的 `items` 为空列表。
+
+## 根本原因
+
+代码中**硬编码**了使用 `amazingdata` 适配器，但配置文件中配置的是 `custom` 适配器。导致：
+
+1. 配置文件中 `sources.futures.active = "custom"`
+2. 但代码中尝试连接 `amazingdata` 适配器
+3. `_connect_adapter` 方法中尝试从 `file_config.sources.stock.list["amazingdata"]` 获取配置
+4. 配置中不存在 `amazingdata`，导致 `KeyError: 'amazingdata'`
+5. 异常被捕获后返回空列表
+
+## 修复内容
+
+### 1. 修复硬编码适配器名称
+
+**修改文件:**
+- `app/services/futures_service.py`
+- `app/services/stock_service.py`
+
+**修改内容:**
+将以下代码:
+```python
+if not adapter:
+    loop.run_until_complete(adapter_service._connect_adapter("amazingdata"))
+```
+
+改为:
+```python
+if not adapter:
+    # 从配置获取当前激活的适配器名称
+    from app.core.config import get_config
+    config = get_config()
+    active_source = config.sources.futures.active  # 或 config.sources.stock.active
+    
+    info(f"Connecting to configured adapter: {active_source}")
+    loop.run_until_complete(adapter_service._connect_adapter(active_source))
+```
+
+### 2. 修复适配器配置获取逻辑
+
+**修改文件:**
+- `app/services/adapter_service.py`
+
+**修改内容:**
+将以下代码:
+```python
+if name == "amazingdata":
+    source_info = file_config.sources.stock.list["amazingdata"]
+    adapter_config = dict(source_info.config) if source_info else {}
+else:
+    adapter_config = self.configs[name].get("config", {})
+```
+
+改为:
+```python
+# 尝试从配置文件中获取适配器配置
+adapter_config = None
+
+# 1. 首先检查 stock 配置
+if name in file_config.sources.stock.list:
+    source_info = file_config.sources.stock.list[name]
+    adapter_config = dict(source_info.config) if source_info else {}
+
+# 2. 然后检查 futures 配置
+elif name in file_config.sources.futures.list:
+    source_info = file_config.sources.futures.list[name]
+    adapter_config = dict(source_info.config) if source_info else {}
+
+# 3. 使用默认配置
+else:
+    adapter_config = self.configs[name].get("config", {})
+```
+
+### 3. 修复期货仓库的频率映射
+
+**修改文件:**
+- `app/repositories/futures_repository.py`
+
+**修改内容:**
+添加了对其他频率的映射（虽然数据库只支持1分钟和日线，但避免KeyError）:
+```python
+def _get_kline_model(self, freq: Frequency):
+    mapping = {
+        Frequency.FREQ_1M: FuturesKLine1M,
+        Frequency.FREQ_1D: FuturesKLine1D,
+        Frequency.FREQ_5M: FuturesKLine1D,   # 默认使用日线
+        Frequency.FREQ_15M: FuturesKLine1D,
+        Frequency.FREQ_30M: FuturesKLine1D,
+        Frequency.FREQ_60M: FuturesKLine1D,
+        Frequency.FREQ_1W: FuturesKLine1D,
+        Frequency.FREQ_1MONTH: FuturesKLine1D,
+    }
+    return mapping.get(freq, FuturesKLine1D)
+```
+
+## 当前状态
+
+API现在可以正常返回响应:
+```json
+{
+  "code": 0,
+  "message": "success",
+  "data": {
+    "symbol": "CU2504.SHFE",
+    "name": null,
+    "freq": "1d",
+    "adjust": "",
+    "count": 0,
+    "items": []
+  }
+}
+```
+
+`items` 为空是因为:
+1. 数据库中没有数据
+2. 配置的 `custom` 适配器未注册（只注册了 `amazingdata`）
+
+## 使用建议
+
+要使接口返回实际数据，需要:
+
+1. **配置 AmazingData 适配器:**
+   修改 `config.json`:
+   ```json
+   {
+     "sources": {
+       "futures": {
+         "active": "amazingdata",
+         "list": {
+           "amazingdata": {
+             "type": "sdk",
+             "config": {
+               "username": "your_username",
+               "password": "your_password",
+               "host": "your_host",
+               "port": "8600"
+             }
+           }
+         }
+       }
+     }
+   }
+   ```
+
+2. **安装 AmazingData SDK:**
+   ```bash
+   pip install AmazingData tgw
+   ```
+
+3. **或者注册自定义适配器:**
+   在 `AdapterService._register_builtin_adapters()` 中添加:
+   ```python
+   self.register_adapter("custom", lambda: YourCustomAdapter())
+   ```

+### 添加告警配置到 config.json:
+
+```json
+{
+  "alert": {
+    "log": {
+      "enabled": true
+    },
+    "dingtalk": {
+      "enabled": false,
+      "webhook_url": "https://oapi.dingtalk.com/robot/send?access_token=xxx",
+      "secret": "your-secret",
+      "at_mobiles": ["13800138000"],
+      "at_all": false
+    },
+    "email": {
+      "enabled": false,
+      "smtp_host": "smtp.example.com",
+      "smtp_port": 587,
+      "username": "alert@example.com",
+      "password": "your-password",
+      "from_addr": "alert@example.com",
+      "to_addrs": ["admin@example.com"],
+      "use_tls": true
+    },
+    "routing": {
+      "info": ["log"],
+      "warning": ["log", "dingtalk"],
+      "error": ["log", "dingtalk", "email"],
+      "critical": ["log", "dingtalk", "email"]
+    }
+  }
+}
+```
+
+---
+
+## API端点更新
+
+### 新增端点:
+
+| 端点 | 方法 | 说明 |
+|------|------|------|
+| `/metrics` | GET | Prometheus指标数据 |
+| `/admin/system/restart` | POST | 重启服务 |
+
+### 限流保护端点:
+
+所有 `/v1/*` 端点（除 `/health`, `/metrics`, `/docs` 等外）都受到限流保护。

+
+## 后续建议
+
+1. **Prometheus集成**
+   - 部署Prometheus服务器抓取 `/metrics` 端点
+   - 配置Grafana仪表板展示指标
+
+2. **告警规则配置**
+   - 配置告警路由规则
+   - 设置钉钉/邮件通道参数
+
+3. **性能优化**
+   - 添加Redis缓存层
+   - 实现数据库连接池监控
+
+4. **安全性增强**
+   - 实现API Key验证逻辑
+   - 添加请求签名验证

+
+## 技术栈
+
+- **语言**: Python 3.10+
+- **Web框架**: FastAPI
+- **WebSocket**: FastAPI原生WebSocket + python-socketio
+- **数据库**: PostgreSQL 15+ (SQLAlchemy ORM)

+
+## 快速开始
+
+### 1. 环境准备
+
+- Python 3.10+
+- PostgreSQL 15+
+- Tushare Token (从 [Tushare官网](https://tushare.pro) 获取)
+
+### 2. 安装依赖
+
+```bash
+# 创建虚拟环境
+python -m venv venv
+
+# 激活虚拟环境
+# Windows:
+venv\Scripts\activate
+# Linux/Mac:
+source venv/bin/activate
+
+# 安装依赖
+pip install -r requirements.txt
+
+# 安装Tushare（需单独安装）
+pip install tushare
+```
+
+### 3. 配置环境变量
+
+```bash
+# Windows PowerShell
+$env:TUSHARE_TOKEN="your_tushare_token"
+$env:DATABASE_URL="postgresql://user:password@localhost:5432/marketdata"
+
+# Linux/Mac
+export TUSHARE_TOKEN="your_tushare_token"
+export DATABASE_URL="postgresql://user:password@localhost:5432/marketdata"
+```
+
+### 4. 初始化数据库
+
+```bash
+# 创建数据库（使用psql或pgAdmin）
+createdb marketdata
+
+# 启动服务时会自动创建表结构
+```
+
+### 5. 启动服务
+
+```bash
+# 开发模式
+python -m app.main
+
+# 或使用uvicorn
+uvicorn app.main:app --reload --port 8080
+```
+
+服务将启动在 `http://localhost:8080`
+
+- API文档: `http://localhost:8080/docs`
+- 管理后台: `http://localhost:8080/admin`
+
+### 6. 同步基础数据
+
+```bash
+# 同步股票列表
+python scripts/sync_data.py --type stocks
+
+# 同步期货列表
+python scripts/sync_data.py --type futures
+
+# 同步交易日历
+python scripts/sync_data.py --type calendar --start 20240101 --end 20241231
+
+# 同步K线数据
+python scripts/sync_data.py --type klines --symbol 000001.SZ --start 20240301 --end 20240307 --freq 1d
+```
+
+## API接口

+| `/v1/futures/trading-dates` | GET | 获取交易日历 |
+| `/v1/futures/contracts` | GET | 获取品种合约列表 |
+
+### 管理接口
+
+| 接口 | 方法 | 说明 |
+|------|------|------|
+| `/v1/admin/source/status` | GET | 获取数据源状态 |
+| `/v1/admin/source/switch` | POST | 切换数据源 |
+| `/v1/admin/backfill` | POST | 历史数据补录 |
+| `/v1/admin/health` | GET | 健康检查 |
+
+### 管理后台
+
+服务启动后，访问 `http://localhost:8080/admin` 进入管理后台。
+
+### WebSocket实时订阅
+
+**连接地址**: `ws://localhost:8080/v1/stream`
+
+**认证**: 连接时在Header中传递 `X-API-Key`
+
+**客户端消息**:
+```json
+// 订阅
+{
+  "action": "subscribe",
+  "symbols": ["000001.SZ", "CU2504.SHFE"]
+}
+
+// 取消订阅
+{
+  "action": "unsubscribe",
+  "symbols": ["000001.SZ"]
+}
+```
+
+**服务器消息**:
+```json
+// 订阅确认
+{
+  "type": "ack",
+  "action": "subscribe",
+  "symbols": ["000001.SZ", "CU2504.SHFE"],
+  "ts": "2025-03-07T12:30:00Z"
+}
+
+// 心跳
+{
+  "type": "heartbeat",
+  "ts": "2025-03-07T12:30:30Z"
+}
+```
+
+**限制**: 单连接最大订阅100个标的
+
+## 与Go版本的主要区别
+
+1. **Web框架**: Gin -> FastAPI
+2. **ORM**: 原生SQL -> SQLAlchemy
+3. **WebSocket**: Gorilla -> FastAPI原生
+4. **配置**: 文件+环境变量 -> Pydantic Settings
+5. **API文档**: 自动生成Swagger/ReDoc
