## Как запретить дополнительные заголовки { #forbid-extra-headers }

В некоторых случаях (не особо часто встречающихся) вам может понадобиться **ограничить** заголовки, которые вы хотите получать.

Вы можете использовать возможности конфигурации Pydantic-модели для того, чтобы запретить (`forbid`) любые дополнительные (`extra`) поля:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}

Dépendances optionnelles supplémentaires pour Pydantic :

* [`pydantic-settings`](https://docs.pydantic.dev/latest/usage/pydantic_settings/) - pour la gestion des paramètres.
* [`pydantic-extra-types`](https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/) - pour des types supplémentaires à utiliser avec Pydantic.

Dépendances optionnelles supplémentaires pour FastAPI :

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

erhält er eine Error-Response, die ihm mitteilt, dass das Feld `extra` nicht erlaubt ist:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
}
```

## Résumer { #summary }

你可以在 `/docs` 页面的 UI 中查看查询参数：

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 禁止额外的查询参数 { #forbid-extra-query-parameters }

在一些特殊的使用场景中（可能不是很常见），你可能希望**限制**你要接收的查询参数。

你可以使用 Pydantic 的模型配置来 `forbid` 任何 `extra` 字段：

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

假设有一个客户端尝试在**查询参数**中发送一些**额外的**数据，它将会收到一个**错误**响应。

## Agregar información extra { #add-extra-information }

Puedes declarar información extra en `Field`, `Query`, `Body`, etc. Y será incluida en el JSON Schema generado.

Aprenderás más sobre cómo agregar información extra más adelante en la documentación, cuando aprendamos a declarar ejemplos.

## Ek Query Parameter'ları Yasaklayın { #forbid-extra-query-parameters }

Bazı özel kullanım senaryolarında (muhtemelen çok yaygın değil), almak istediğiniz query parameter’ları **kısıtlamak** isteyebilirsiniz.

Pydantic’in model konfigürasyonunu kullanarak `extra` field’ları `forbid` edebilirsiniz:

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

- The API server and client-go libraries have been fixed to support additional non-alpha-numeric characters in UserInfo "extra" data keys. Both should be updated in order to properly support extra data containing "/" characters or other characters disallowed in HTTP headers.
