* `headers` - Um dicionário `dict` de strings.
* `media_type` - Uma `str` informando o media type. E.g. `"text/html"`.

O FastAPI (Starlette, na verdade) irá incluir o cabeçalho Content-Length automaticamente. Ele também irá incluir o cabeçalho Content-Type, baseado no `media_type` e acrescentando uma codificação para tipos textuais.
