     * Serialize the inbound Model instance to a StringWriter, perform the regex replacement to resolve

Crea un response como se describe en [Retorna un Response Directamente](response-directly.md) y pasa los headers como un parámetro adicional:

{* ../../docs_src/response_headers/tutorial001_py310.py hl[10:12] *}

/// note | Detalles Técnicos

También podrías usar `from starlette.responses import Response` o `from starlette.responses import JSONResponse`.

Isso permitiria que você **reutilizasse o modelo** em **diversos lugares**, e também declarasse validações e metadados de todos os parâmetros de uma única vez. 😎

/// note | Nota

Isso é suportado desde o FastAPI versão `0.115.0`. 🤓

And we can add a list of `dependencies` that will be added to all the *path operations* in the router and will be executed/solved for each request made to them.

/// tip

Note that, much like [dependencies in *path operation decorators*](dependencies/dependencies-in-path-operation-decorators.md), no value will be passed to your *path operation function*.

///

一方で、*path operation デコレータ* の `response_class` パラメータを使って、使用したい `Response`（`Response` の任意のサブクラス）を宣言することもできます。

*path operation 関数* から返したコンテンツは、その `Response` に格納されます。

/// note | 備考

メディアタイプを持たないレスポンスクラスを使用すると、FastAPIはレスポンスにコンテンツがないものと見なします。そのため、生成されるOpenAPIドキュメントにレスポンスフォーマットは記載されません。

///

## JSONレスポンス { #json-responses }

FastAPI はデフォルトでJSONレスポンスを返します。
