|
|
## 文件 1: backend/app/__init__.py
|
|
空文件。
|
|
|
|
## 文件 2: backend/app/config.py
|
|
```python
|
|
"""应用配置 — 从环境变量 / .env 读取。"""

|
from pydantic_settings import BaseSettings
|
|
|
|
|
|
class Settings(BaseSettings):
|
|

|
|
jwt_secret: str = "change-me"
|
|
jwt_algorithm: str = "HS256"
|
|
jwt_expire_minutes: int = 1440
|
|
hermes_cli_path: str = "/home/enzo/.local/bin/hermes"
|
|
hermes_profiles_root: str = "/home/enzo/.hermes/profiles"
|
|
admin_email: str = "admin@zhiwei.local"

## 文件 3: backend/app/database.py
|
|
```python
|
|
"""异步 SQLAlchemy 引擎 + session 工厂。"""
|
|
from sqlalchemy.ext.asyncio import create_async_engine, async_sessionmaker, AsyncSession

|
|
from app.config import settings
|
|
|
|

|
|
async_session = async_sessionmaker(engine, class_=AsyncSession, expire_on_commit=False)
|
|
|
|
|
|
class Base(DeclarativeBase):
|
|
pass
|
|
|
|
|
|
async def get_db() -> AsyncSession:
|
|
async with async_session() as session:
|
|
yield session
|
|
```
|
|
|
|
## 文件 4: backend/app/main.py
|
|
```python
|
|
"""FastAPI 应用入口。"""
|
|
from contextlib import asynccontextmanager
|
|
from fastapi import FastAPI
|
|
from fastapi.middleware.cors import CORSMiddleware
|
|
|
|
from app.database import engine, Base
|
|
|
|
|
|
@asynccontextmanager
|
|
async def lifespan(app: FastAPI):
|
|
async with engine.begin() as conn:
|
|
await conn.run_sync(Base.metadata.create_all)
|
|
yield
|
|
await engine.dispose()
|
|
|
|
|
|
app = FastAPI(
|
|
title="Hive Manage v3",
|
|
version="0.1.0",
|
|
lifespan=lifespan,
|
|
)
|
|
|
|
app.add_middleware(
|
|
CORSMiddleware,
|
|

|
|
allow_credentials=True,
|
|
allow_methods=["*"],
|
|
allow_headers=["*"],
|
|

|
|
|
|
|
|
@app.get("/api/v1/health")
|
|
async def health_check():
|
|
return {"status": "ok"}
|
|
```
|
|
|
|
创建完成后，执行以下验证：
|
|
1. `cat` 检查每个文件内容
|
|
2. `cd backend && pip install -e ".[dev]"` 安装依赖
|
|
3. `cd backend && python -c "from app.main import app; print('FastAPI app created OK')"` 验证导入
|
|
4. git add + git commit -m "feat: FastAPI skeleton with config, database, health endpoint"
