需要注意，如果你直接反馈一个response对象，而不是使用`Response`入参，FastAPI则会直接反馈你封装的response对象。

所以你需要确保你响应数据类型的正确性，如：你可以使用`JSONResponse`来兼容JSON的场景。

同时，你也应当仅反馈通过`response_model`过滤过的数据。

///

### 更多信息 { #more-info }

/// note | 技术细节

你也可以使用`from starlette.responses import Response` 或者 `from starlette.responses import JSONResponse`。

为了方便开发者，**FastAPI** 封装了相同数据类型，如`starlette.responses` 和 `fastapi.responses`。不过大部分response对象都是直接引用自Starlette。
