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.

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

Poor cookie banners with all their effort to get your consent for the <abbr title="This is another joke. Don't pay attention to me. Have some coffee for your cookie. ☕">API to reject it</abbr>. 🍪

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.

In your WebSocket route you can `await` for messages and send messages.

{* ../../docs_src/websockets/tutorial001_py39.py hl[48:52] *}

You can receive and send binary, text, and JSON data.

## Try it { #try-it }

If your file is named `main.py`, run your application with:

<div class="termy">

```console
$ fastapi dev main.py

`PUT` is used to receive data that should replace the existing data.

### Warning about replacing { #warning-about-replacing }

That means that if you want to update the item `bar` using `PUT` with a body containing:

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.

O dicionário `scope` e a função `receive` são ambos parte da especificação ASGI.

E essas duas coisas, `scope` e `receive`, são o que é necessário para criar uma nova instância de `Request`.
