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。

例如，如果客户端尝试发送一个值为 `plumbus` 的 `tool` 查询参数，如：

```http
https://example.com/items/?limit=10&tool=plumbus
```

他们将收到一个**错误**响应，告诉他们查询参数 `tool` 是不允许的：

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

Pydantic 모델은 모델 데이터를 포함한 `dict`를 반환하는 `.dict()` 메서드를 제공합니다.

따라서, 다음과 같이 Pydantic 객체 `user_in`을 생성할 수 있습니다:

```Python
user_in = UserIn(username="john", password="secret", email="john.doe@example.com")
```

그 다음, 다음과 같이 호출합니다:

```Python
user_dict = user_in.dict()
```

이제 변수 `user_dict`에 데이터가 포함된 `dict`를 가지게 됩니다(이는 Pydantic 모델 객체가 아닌 `dict`입니다).

그리고 다음과 같이 호출하면:

```Python
