`example` と `examples`について...

JSON Schemaの最新バージョンでは<a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>というフィールドを定義していますが、OpenAPIは`examples`を持たない古いバージョンのJSON Schemaをベースにしています。

## Sobre "Campos de formulário" { #about-form-fields }

A forma como os formulários HTML (`<form></form>`) enviam os dados para o servidor normalmente usa uma codificação "especial" para esses dados, é diferente do JSON.

O **FastAPI** fará a leitura desses dados no lugar certo em vez de JSON.
