## Tipos e Validação { #types-and-validation }

Essas variáveis de ambiente só podem lidar com **strings de texto**, pois são externas ao Python e precisam ser compatíveis com outros programas e com o resto do sistema (e até mesmo com diferentes sistemas operacionais, como Linux, Windows, macOS).

/// note | Detalles Técnicos

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 ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) using the parameter `expose_headers` documented in <a href="https://www.starlette.dev/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette's CORS docs</a>.

하지만, 여러분이 브라우저에서 클라이언트가 볼 수 있기를 원하는 커스텀 헤더가 있는 경우, CORS 설정에 이를 추가해야 합니다([CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md){.internal-link target=_blank}에서 자세히 알아보세요). `expose_headers` 매개변수를 사용하여 <a href="https://www.starlette.dev/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette의 CORS 설명서</a>에 문서화된 대로 설정할 수 있습니다....
