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

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

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

## Try it

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

<div class="termy">

```console
$ fastapi dev main.py

Deste modo, ao utilizar `secrets.compare_digest()` no código de sua aplicação, ela estará a salvo contra toda essa gama de ataques de segurança.

* Передаёте JSON в теле запроса, передав Python-объект (например: `dict`) через именованный параметр `json`.
* Если же Вам необходимо отправить *форму с данными* вместо JSON, то используйте параметр `data` вместо `json`.
* Для передачи *заголовков*, передайте объект `dict` через параметр `headers`.
* Для передачи *cookies* также передайте `dict`, но через параметр `cookies`.
