## Caso de uso { #use-case }

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

Pero si los datos no existieran, quieres crearlos y devolver un código de estado HTTP de "CREATED" `201`.

Pero todavía quieres poder filtrar y convertir los datos que devuelves con un `response_model`.

Para esos casos, puedes usar un parámetro `Response`.

## Usa un parámetro `Response` { #use-a-response-parameter }

     * @param userToolchainsSource The {@link Source} pointing to the user toolchains, must not be {@code null}
     * @throws ToolchainsBuilderException if the project cannot be created
     * @throws IllegalArgumentException if an argument is {@code null} or invalid
     * @see #build(ToolchainsBuilderRequest)

Sie möchten aber auch, dass sie neue Artikel akzeptiert. Und wenn die Artikel vorher nicht vorhanden waren, werden diese Artikel erstellt und der HTTP-Statuscode 201 „Created“ zurückgegeben.

Um dies zu erreichen, importieren Sie `JSONResponse`, und geben Sie Ihren Inhalt direkt zurück, indem Sie den gewünschten `status_code` setzen:

Но вы также хотите, чтобы она принимала новые элементы. И если элементы ранее не существовали, она создаёт их и возвращает HTTP статус-код 201 «Created».

Чтобы добиться этого, импортируйте `JSONResponse` и верните туда свой контент напрямую, установив нужный вам `status_code`:

	Text     string      `json:"text,omitempty"`
	Mail     bool        `json:"mail,omitempty"` // Be an MX record. Priority becomes Preference.
	TTL      uint32      `json:"ttl,omitempty"`

	// Holds info about when the entry was created first.
	CreationDate time.Time `json:"creationDate"`

	// When a SRV record with a "Host: IP-address" is added, we synthesize
	// a srv.Target domain name.  Normally we convert the full Key where
