Mas se você tiver cabeçalhos personalizados desejando que um cliente em um navegador esteja apto a ver, você precisa adicioná-los às suas configurações CORS ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) usando o parâmetro `expose_headers` documentado em <a href="https://www.starlette.io/middleware/#corsmiddleware"...

headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the 'X-' prefix</a>.

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations (read more in [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md){.internal-link target=_blank}), using the parameter `expose_headers` documented in <a href="https://www.starlette.io/middleware/#corsmiddleware"...

sería válida para usar como una dependencia en **FastAPI**.

### Instalar `pydantic-settings`

Primero, asegúrate de crear tu [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo y luego instala el paquete `pydantic-settings`:

<div class="termy">

```console

[*경로 작동 데코레이터*에 `dependencies` 추가하기](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}와 유사한 방법으로 `FastAPI` 애플리케이션에 그것들을 추가할 수 있습니다.

그런 경우에, 애플리케이션의 모든 *경로 작동*에 적용될 것입니다:

{* ../../docs_src/dependencies/tutorial012_an_py39.py hl[16] *}

그리고 [*경로 작동 데코레이터*에 `dependencies` 추가하기](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}에 대한 아이디어는 여전히 적용되지만 여기에서는 앱에 있는 모든 *경로 작동*에 적용됩니다.
