# Séparer les schémas OpenAPI pour l'entrée et la sortie ou non { #separate-openapi-schemas-for-input-and-output-or-not }

Depuis la sortie de **Pydantic v2**, l'OpenAPI généré est un peu plus précis et **correct** qu'avant. 😎

En fait, dans certains cas, il y aura même **deux schémas JSON** dans OpenAPI pour le même modèle Pydantic, pour l'entrée et pour la sortie, selon s'ils ont des **valeurs par défaut**.

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}

/// info | Informação

`Body` também possui todas as validações adicionais e metadados de parâmetros como em `Query`,`Path` e outras que você verá depois.

///

## Declare um único parâmetro de corpo indicando sua chave { #embed-a-single-body-parameter }

Suponha que você tem um único parâmetro de corpo `item`, a partir de um modelo Pydantic `Item`.

此處查詢參數 `needy` 是必填的 `str`。

如果你在瀏覽器中開啟如下的 URL：

```
http://127.0.0.1:8000/items/foo-item
```

...沒有加上必填的 `needy` 參數，你會看到類似這樣的錯誤：

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
