En este ejemplo, no declaramos ningún modelo Pydantic. De hecho, el cuerpo del request ni siquiera se <abbr title="convertido de algún formato plano, como bytes, a objetos de Python">parse</abbr> como JSON, se lee directamente como `bytes`, y la función `magic_data_reader()` sería la encargada de parsearlo de alguna manera.

Sin embargo, podemos declarar el esquema esperado para el cuerpo del request.

вы получите текстовую версию:
