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`.

Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Body des Requests <abbr title="Englisch „receive“">empfängt</abbr>.

Das `scope`-`dict` und die `receive`-Funktion sind beide Teil der ASGI-Spezifikation.

Und diese beiden Dinge, `scope` und `receive`, werden benötigt, um eine neue `Request`-Instanz zu erstellen.

        }
    }

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.

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

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

You can define files to be uploaded by the client using `File`.

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:
