简介
FastAPI是流行的Python web框架，适用于开发高吞吐量API和微服务（直接支持异步编程）
FastAPI的优势之一：通过提供高级抽象和自动数据模型转换，简化请求数据的处理（用户不需要手动处理原始请求数据），并能根据路由和 Pydantic 模型自动生成 OpenAPI 接口文档。
- Swagger UI
- ReDoc

) -> UserOut:user.request_id = uuid.uuid4()print(user.request_id)return userif __name__ == '__main__':uvicorn.run(app=app, access_log=True, port=9988)运行后，会提示Uvicorn running on http://127.0.0.1:9988 (Press CTRL+C to quit)
在浏览器输入http://127.0.0.1:9988/redoc（ ReDoc）,http://127.0.0.1:9988/docs（Swagger UI ）即可查看
ReDoc 页面如下：
ReDoc vs. Swagger UI
ReDoc更美观，Swagger UI更注重交互（用户直接从界面中发送请求，查看响应，这对于测试和调试 API 非常有用。）
