然后，**FastAPI** 会在后台将这些兼容 JSON 的数据（比如字典）放到一个 `JSONResponse` 中，该 `JSONResponse` 会用来发送响应给客户端。

但是你可以在你的 *路径操作* 中直接返回一个 `JSONResponse`。

直接返回响应可能会有用处，比如返回自定义的响应头和 cookies。

## 返回 `Response`

事实上，你可以返回任意 `Response` 或者任意 `Response` 的子类。

!!! tip "小贴士"
    `JSONResponse` 本身是一个 `Response` 的子类。

当你返回一个 `Response` 时，**FastAPI** 会直接传递它。

Luego, tras bastidores, pondría esos datos compatibles con JSON (por ejemplo, un `dict`) dentro de una `JSONResponse` que se usaría para enviar la respuesta al cliente.

Pero puedes devolver una `JSONResponse` directamente de tu *operación de path*.

Esto puede ser útil, por ejemplo, para devolver cookies o headers personalizados.

## Devolver una `Response`
