## まとめ

リクエストが単一のボディしか持てない場合でも、*path operation関数*に複数のボディパラメータを追加することができます。

しかし、**FastAPI** はそれを処理し、関数内の正しいデータを与え、*path operation*内の正しいスキーマを検証し、文書化します。

また、ボディの一部として受け取る単数値を宣言することもできます。

### Проверьте документацию

Теперь, если вы проверите документацию, вы увидите всю дополнительную информацию:

        return value;
      }
    };
  }

  private static <K extends @Nullable Object, V extends @Nullable Object> Entry<K, V> control(
      K key, V value) {
    return singletonMap(key, value).entrySet().iterator().next();
  }

  public void testToString() {
    assertEquals("foo=1", entry("foo", 1).toString());
  }

  public void testToStringNull() {
    assertEquals("null=1", entry(NK, 1).toString());

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

Cela va valider les données, montrer une erreur claire si ces dernières ne sont pas valides, et documenter le paramètre dans le schéma `OpenAPI` de cette *path operation*.

## Rajouter plus de validation

Vous pouvez aussi rajouter un second paramètre `min_length` :
