**FastAPI** will make sure to read that data from the right place instead of JSON.

/// note | Technical Details

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded` when it doesn't include files.

But when the form includes files, it is encoded as `multipart/form-data`. If you use `File`, **FastAPI** will know it has to get the files from the correct part of the body.

**FastAPI** se certificará de ler esses dados do lugar certo, ao invés de JSON.

/// note | Detalhes Técnicos

Dados de formulários normalmente são codificados usando o "media type" (tipo de mídia) `application/x-www-form-urlencoded` quando não incluem arquivos.

Mas quando o formulário inclui arquivos, ele é codificado como `multipart/form-data`. Se você usar `File`, o **FastAPI** saberá que tem que pegar os arquivos da parte correta do corpo da requisição.
