docs/ru/docs/how-to/configure-swagger-ui.md

Чтобы настроить их, передайте аргумент `swagger_ui_parameters` при создании объекта приложения `FastAPI()` или в функцию `get_swagger_ui_html()`.

`swagger_ui_parameters` принимает словарь с настройками, которые передаются в Swagger UI напрямую.

FastAPI преобразует эти настройки в **JSON**, чтобы они были совместимы с JavaScript, поскольку именно это требуется Swagger UI.

docs/pt/docs/advanced/response-headers.md

**FastAPI** fornece as mesmas `starlette.responses` como `fastapi.responses` apenas como uma conveniência para você, desenvolvedor. Mas a maioria das respostas disponíveis vem diretamente do Starlette.

E como a `Response` pode ser usada frequentemente para definir cabeçalhos e cookies, **FastAPI** também a fornece em `fastapi.Response`.

///

## Cabeçalhos personalizados { #custom-headers }

* El path como parámetros.
* Headers.
* Cookies.
* etc.

Y al hacerlo, **FastAPI** está validando esos datos, convirtiéndolos y generando documentación para tu API automáticamente.

Pero hay situaciones donde podrías necesitar acceder al objeto `Request` directamente.
