Avec `Query` et `Path` (et d'autres que vous verrez plus tard) vous pouvez déclarer des contraintes numériques.

Ici, avec `ge=1`, `item_id` devra être un nombre entier "`g`reater than or `e`qual" à `1`.

## Definir Parâmetros `File`

Crie parâmetros de arquivo da mesma forma que você faria para `Body` ou `Form`:
