- `media_type` - Une `str` donnant le media type. Par exemple « text/html ».

FastAPI (en fait Starlette) inclura automatiquement un en-tête Content-Length. Il inclura aussi un en-tête Content-Type, basé sur `media_type` et en ajoutant un charset pour les types textuels.

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.
