* Documentation automatique des modèles de données avec <a href="http://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (comme OpenAPI est aussi basée sur JSON Schema).
* Conçue avec ces standards après une analyse méticuleuse. Plutôt qu'en rajoutant des surcouches après coup.

* Otomatik olarak data modelinin <a href="http://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> ile beraber dokümante edilmesi (OpenAPI'n kendisi zaten JSON Schema'ya dayanıyor).

standardmäßig jedes enthaltene Element überprüft und sicherstellt, dass es als JSON serialisierbar ist, und zwar unter Verwendung desselben [JSON-kompatiblen Encoders](../tutorial/encoder.md){.internal-link target=_blank}, der im Tutorial erläutert wurde. Dadurch können Sie **beliebige Objekte** zurückgeben, zum Beispiel Datenbankmodelle.

Wenn Sie jedoch sicher sind, dass der von Ihnen zurückgegebene Inhalt **mit JSON serialisierbar** ist, können Sie ihn direkt an die Response-Klasse übergeben...

	"encoding/xml"

	Key     string   `xml:"Key,omitempty" json:"Key,omitempty"`
	Value   string   `xml:"Value,omitempty" json:"Value,omitempty"`
}

	errInvalidTagKey   = Errorf("The TagKey you have provided is invalid")

You can return *enum members* from your *path operation*, even nested in a JSON body (e.g. a `dict`).

They will be converted to their corresponding values (strings in this case) before returning them to the client:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

In your client you will get a JSON response like:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"

Ellos serán convertidos a sus valores correspondientes (strings en este caso) antes de devolverlos al cliente:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

En tu cliente obtendrás una respuesta en JSON como:

```JSON
{
  "model_name": "alexnet",

		return
