Zum Beispiel, wenn der Client versucht, folgende Formularfelder zu senden:

* `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": [
        {

Si un client tente d'envoyer des données supplémentaires, il recevra une **réponse d'erreur**.

Par exemple, si le client essaie d'envoyer les champs de formulaire :

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

Il recevra une réponse d'erreur lui indiquant que le champ `extra` n'est pas autorisé :

```json
{
    "detail": [
        {

///

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

{* ../../docs_src/request_form_models/tutorial002_an_py310.py hl[12] *}

如果客户端尝试发送一些额外的数据，他们将收到**错误**响应。

例如，客户端尝试发送如下表单字段：

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

他们将收到一条错误响应，表明字段 `extra` 不被允许：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

    end

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Rick")
        function ->> execute: execute function code
        execute ->> code: return the result
    end

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Rick", salutation="Mr.")
        function ->> execute: execute function code
        execute ->> code: return the result
    end

    end

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Rick")
        function ->> execute: execute function code
        execute ->> code: return the result
    end

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Rick", salutation="Mr.")
        function ->> execute: execute function code
        execute ->> code: return the result
