Также можно использовать `from starlette.requests import Request` и `from starlette.responses import JSONResponse`.

**FastAPI** предоставляет тот же `starlette.responses`, что и `fastapi.responses`, просто для удобства разработчика. Однако большинство доступных ответов поступает непосредственно из Starlette. То же самое касается и `Request`.
