Pero hay situaciones donde podrías necesitar acceder al objeto `Request` directamente.

## Detalles sobre el objeto `Request` { #details-about-the-request-object }

Como **FastAPI** es en realidad **Starlette** por debajo, con una capa de varias herramientas encima, puedes usar el objeto de Starlette [`Request`](https://www.starlette.dev/requests/) directamente cuando lo necesites.

	if crypto.S3.IsRequested(r.Header) || crypto.S3KMS.IsRequested(r.Header) { // If SSE-S3 or SSE-KMS present -> AWS fails with undefined error
		writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrBadRequest), r.URL)
		return
	}

	zipPath, object, err := splitZipExtensionPath(object)
	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in [ISO format](https://en.wikipedia.org/wiki/ISO_8601).

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

You can use `jsonable_encoder` for that.
