De nombreux packages qui la simplifient beaucoup doivent faire de nombreux compromis avec le modèle de données, la base de données et les fonctionnalités disponibles. Et certains de ces packages qui simplifient trop les choses comportent en fait des failles de sécurité sous-jacentes.

---

**FastAPI** ne fait aucun compromis avec une base de données, un modèle de données ni un outil.

Adotar temporariamente esse ponto de vista (do *desenvolvedor externo*) pode ajudar a perceber mais facilmente onde colocar os parâmetros, o modelo Pydantic para o corpo, para a resposta, etc. para essa *API externa*.

### Crie um `APIRouter` de callback { #create-a-callback-apirouter }

Primeiro crie um novo `APIRouter` que conterá um ou mais callbacks.

Вы можете объявлять примеры данных, которые ваше приложение может получать.

Вот несколько способов, как это сделать.

## Дополнительные данные JSON Schema в моделях Pydantic { #extra-json-schema-data-in-pydantic-models }

Вы можете объявить `examples` для модели Pydantic, которые будут добавлены в сгенерированную JSON Schema.
