Спойлер: вы также можете использовать Pydantic-модели для группировки кук (cookies) и заголовков (headers), но об этом вы прочитаете позже. 🤫

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.
