You can use Pydantic's model configuration to `forbid` any `extra` fields:

If a client tries to send some **extra** data in the **query parameters**, they will receive an **error** response.

A `Request` also has a `request.receive`, that's a function to "receive" the body of the request.

The `scope` `dict` and `receive` function are both part of the ASGI specification.

And those two things, `scope` and `receive`, are what is needed to create a new `Request` instance.

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

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

They will receive an error response telling them that the field `extra` is not allowed:

```json

    "detail": [

`Request`에는 `request.scope` 속성이 있는데, 이는 요청과 관련된 메타데이터를 담고 있는 Python `dict`입니다.

`Request`에는 또한 `request.receive`가 있는데, 이는 요청의 바디를 "받기(receive)" 위한 함수입니다.

`scope` `dict`와 `receive` 함수는 모두 ASGI 명세의 일부입니다.

그리고 이 두 가지, `scope`와 `receive`가 새로운 `Request` 인스턴스를 만드는 데 필요한 것들입니다.

`Request`에 대해 더 알아보려면 [Starlette의 Requests 문서](https://www.starlette.dev/requests/)를 확인하세요.

У `Request` также есть `request.receive` — функция для «получения» тела запроса.

И `dict` `scope`, и функция `receive` являются частью спецификации ASGI.

Именно этих двух компонентов — `scope` и `receive` — достаточно, чтобы создать новый экземпляр `Request`.
