## 代码模式
|
||
|
||
### API 响应格式 (FastAPI)
|
||
|
||
```python
|
||
from pydantic import BaseModel
|
||
from typing import Generic, TypeVar, Optional
|
||
|
||
T = TypeVar('T')
|
||
|
||
class ApiResponse(BaseModel, Generic[T]):
|
||
success: bool
|
||
data: Optional[T] = None
|
||
error: Optional[str] = None
|
||
|
||
@classmethod
|
||
def ok(cls, data: T) -> "ApiResponse[T]":
|
||
return cls(success=True, data=data)
|
||
|
||
@classmethod
|
||
def fail(cls, error: str) -> "ApiResponse[T]":
|
||
return cls(success=False, error=error)
|
||
```
|
||
|
||
### 前端 API 调用 (TypeScript)
|
||
|
||
```typescript
|
||
interface ApiResponse<T> {
|
||
success: boolean
|
||
data?: T
|
||
error?: string
|
||
}
|
||
|
||
async function fetchApi<T>(
|
||
endpoint: string,
|
||
options?: RequestInit
|
||
): Promise<ApiResponse<T>> {
|
||
try {
|
||
const response = await fetch(`/api${endpoint}`, {
|
||
...options,
|
||
headers: {
|
||
'Content-Type': 'application/json',
|
||
...options?.headers,
|
||
},
|
||
})
|
||
|
||
if (!response.ok) {
|
||
return { success: false, error: `HTTP ${response.status}` }
|
||
}
|
||
|
||
return await response.json()
|
||
} catch (error) {
|
||
return { success: false, error: String(error) }
|
||
}
|
||
}
|
||
```
|
||
|
||
### Claude AI 集成 (结构化输出)
|
||
|
||
```python
|
||
from anthropic import Anthropic
|
||
from pydantic import BaseModel
|
||
|
||
class AnalysisResult(BaseModel):
|
||
summary: str
|
||
key_points: list[str]
|
||
confidence: float
|
||
|
||
async def analyze_with_claude(content: str) -> AnalysisResult:
|
||
client = Anthropic()
|
||
|
||
response = client.messages.create(
|
||
model="claude-sonnet-4-5-20250514",
|
||
max_tokens=1024,
|
||
messages=[{"role": "user", "content": content}],
|
||
tools=[{
|
||
"name": "provide_analysis",
|
||
"description": "Provide structured analysis",
|
||
"input_schema": AnalysisResult.model_json_schema()
|
||
}],
|
||
tool_choice={"type": "tool", "name": "provide_analysis"}
|
||
)
|
||
|
||
# Extract tool use result
|
||
tool_use = next(
|
||
block for block in response.content
|
||
if block.type == "tool_use"
|
||
)
|
||
|
||
return AnalysisResult(**tool_use.input)
|
||
```
|
||
|
||
### 自定义 Hooks (React)
|
||
|
||
```typescript
|
||
import { useState, useCallback } from 'react'
|
||
|
||
interface UseApiState<T> {
|
||
data: T | null
|
||
loading: boolean
|
||
error: string | null
|
||
}
|
||
|
||
export function useApi<T>(
|
||
fetchFn: () => Promise<ApiResponse<T>>
|
||
) {
|
||
const [state, setState] = useState<UseApiState<T>>({
|
||
data: null,
|
||
loading: false,
|
||
error: null,
|
||
})
|
||
|
||
const execute = useCallback(async () => {
|
||
setState(prev => ({ ...prev, loading: true, error: null }))
|
||
|
||
const result = await fetchFn()
|
||
|
||
if (result.success) {
|
||
setState({ data: result.data!, loading: false, error: null })
|
||
} else {
|
||
setState({ data: null, loading: false, error: result.error! })
|
||
}
|
||
}, [fetchFn])
|
||
|
||
return { ...state, execute }
|
||
}
|
||
```
|
||
|
||
***
|
||
|
||
## 测试要求
|
||
|
||
### 后端 (pytest)
|
||
|
||
```bash
|
||
# Run all tests
|
||
poetry run pytest tests/
|
||
|
||
# Run with coverage
|
||
poetry run pytest tests/ --cov=. --cov-report=html
|
||
|
||
# Run specific test file
|
||
poetry run pytest tests/test_auth.py -v
|
||
```
|
||
|
||
**测试结构：**
|
||
|
||
```python
|
||
import pytest
|
||
from httpx import AsyncClient
|
||
from main import app
|
||
|
||
@pytest.fixture
|
||
async def client():
|
||
async with AsyncClient(app=app, base_url="http://test") as ac:
|
||
yield ac
|
||
|
||
@pytest.mark.asyncio
|
||
async def test_health_check(client: AsyncClient):
|
||
response = await client.get("/health")
|
||
assert response.status_code == 200
|
||
assert response.json()["status"] == "healthy"
|
||
```
|
||
|
||
### 前端 (React Testing Library)
|
||
|
||
```bash
|
||
# Run tests
|
||
npm run test
|
||
|
||
# Run with coverage
|
||
npm run test -- --coverage
|
||
|
||
# Run E2E tests
|
||
npm run test:e2e
|
||
```
|
||
|
||
**测试结构：**
|
||
|
||
```typescript
|
||
import { render, screen, fireEvent } from '@testing-library/react'
|
||
import { WorkspacePanel } from './WorkspacePanel'
|
||
|
||
describe('WorkspacePanel', () => {
|
||
it('renders workspace correctly', () => {
|
||
render(<WorkspacePanel />)
|
||
expect(screen.getByRole('main')).toBeInTheDocument()
|
||
})
|
||
|
||
it('handles session creation', async () => {
|
||
render(<WorkspacePanel />)
|
||
fireEvent.click(screen.getByText('New Session'))
|
||
expect(await screen.findByText('Session created')).toBeInTheDocument()
|
||
})
|
||
})
|
||
```
|
||
|
||
***
|
||
|
||
## 部署工作流
|
||
|
||
### 部署前检查清单
|
||
|
||
* \[ ] 所有测试在本地通过
|
||
* \[ ] `npm run build` 成功 (前端)
|
||
* \[ ] `poetry run pytest` 通过 (后端)
|
||
* \[ ] 没有硬编码的密钥
|
||
* \[ ] 环境变量已记录
|
||
* \[ ] 数据库迁移就绪
|
||
|
||
### 部署命令
|
||
|
||
```bash
|
||
# Build and deploy frontend
|
||
cd frontend && npm run build
|
||
gcloud run deploy frontend --source .
|
||
|
||
# Build and deploy backend
|
||
cd backend
|
||
gcloud run deploy backend --source .
|
||
```
|
||
|
||
### 环境变量
|
||
|
||
```bash
|
||
# Frontend (.env.local)
|
||
NEXT_PUBLIC_API_URL=https://api.example.com
|
||
NEXT_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
|
||
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJ...
|
||
|
||
# Backend (.env)
|
||
DATABASE_URL=postgresql://...
|
||
ANTHROPIC_API_KEY=sk-ant-...
|
||
SUPABASE_URL=https://xxx.supabase.co
|
||
SUPABASE_KEY=eyJ...
|
||
```
|
||
|
||
***
|
||
|
||
## 关键规则
|
||
|
||
1. 在代码、注释或文档中**不使用表情符号**
|
||
2. **不可变性** - 永不改变对象或数组
|
||
3. **测试驱动开发 (TDD)** - 在实现之前编写测试
|
||
4. **最低 80% 覆盖率**
|
||
5. **许多小文件** - 典型 200-400 行，最多 800 行
|
||
6. 在生产代码中**不使用 console.log**
|
||
7. 使用 try/catch 进行**适当的错误处理**
|
||
8. 使用 Pydantic/Zod 进行**输入验证**
