	+ [OpenAPI响应对象](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responseObject)，您可以直接在 `responses` 参数中的每个响应中包含任何内容。包括 `description` 、 `headers` 、 `content` （其中是声明不同的媒体类型和JSON Schemas）和 `links` 。...

* Proporcionar los datos recibidos en el parámetro `item`.
    * Como lo declaraste en la función como de tipo `Item`, también tendrás todo el soporte del editor (autocompletado, etc.) para todos los atributos y sus tipos.

// ParseHTTP parses the SSE-S3 related HTTP headers and checks
// whether they contain valid values.
func (sses3) ParseHTTP(h http.Header) error {

}

But you can return a `JSONResponse` directly from your *path operations*.

It might be useful, for example, to return custom headers or cookies.

## Return a `Response` { #return-a-response }

In fact, you can return any `Response` or any sub-class of it.

/// tip

`JSONResponse` itself is a sub-class of `Response`.
