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`

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

/// tip

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

///

type RequestRecorder struct {
	// Data source to record
	io.Reader
	// Response body should be logged
	LogBody bool

	// internal recording buffer
	buf bytes.Buffer
	// total bytes read including header size
	bytesRead int
}

// Close is a no operation closer
func (r *RequestRecorder) Close() error {
	// no-op
	return nil
}

// Read reads from the internal reader and counts/save the body in the memory

## `examples` im JSON-Schema – OpenAPI

Bei Verwendung von:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

können Sie auch eine Gruppe von `examples` mit zusätzlichen Informationen deklarieren, die zu ihren **JSON-Schemas** innerhalb von **OpenAPI** hinzugefügt werden.

import (
	"github.com/tinylib/msgp/msgp"
)

// MarshalMsg implements msgp.Marshaler
func (z *MetricDescription) MarshalMsg(b []byte) (o []byte, err error) {
	o = msgp.Require(b, z.Msgsize())
	// map header, size 5
	// string "Namespace"
	o = append(o, 0x85, 0xa9, 0x4e, 0x61, 0x6d, 0x65, 0x73, 0x70, 0x61, 0x63, 0x65)
	o = msgp.AppendString(o, string(z.Namespace))
	// string "Subsystem"

## Contents properties

All properties except the file size are tied to the zip file. This means that modification date, headers, tags, etc. can only be set for the zip file as a whole. In similar fashion, replication will replicate the zip file as a whole and not individual files.

## Code Examples

		apiErr.Description = err.Error()
		writeErrorResponse(ctx, w, apiErr, url)
		return
	}
}

// Parses x-amz-copy-source-range for CopyObjectPart API. Its behavior
// is different from regular HTTP range header. It only supports the
// form `bytes=first-last` where first and last are zero-based byte
// offsets. See
// http://docs.aws.amazon.com/AmazonS3/latest/API/mpUploadUploadPartCopy.html

/// tip | "Dica"

Tenha em mente que cabeçalhos proprietários personalizados podem ser adicionados <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">usando o prefixo 'X-'</a>.

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`

De hecho, puedes devolver cualquier `Response` o cualquier subclase de la misma.

/// tip | Consejo

`JSONResponse` en sí misma es una subclase de `Response`.

COPY ./app /code/app

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]

# Если используете прокси-сервер, такой как Nginx или Traefik, добавьте --proxy-headers
# CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80", "--proxy-headers"]
