from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


@app.get("/")
async def root():
    return {"message": "Hello World"}


# 需求：新闻接口 → 响应数据格式 id、title、content
class News(BaseModel):
    id: int
    title: str
    content: str


@app.get("/news/{id}", response_model=News)
async def get_news(id: int):
    return {
        "id": id,
        "title": f"这是第{id}本书",
        "content": "这是一本好书"
    }
