Si vous ne voulez pas utiliser des modèles Pydantic, vous pouvez aussi utiliser des paramètres de **Corps**. Pour cela, allez voir la partie de la documentation sur  [Corps de la requête - Paramètres multiples](body-multiple-params.md){.internal-link target=_blank}....

여러분은 **FastAPI**에서 <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a>를 사용할 수 있습니다.

## `WebSockets` 설치

[가상 환경](../virtual-environments.md){.internal-link target=_blank)를 생성하고 활성화한 다음, `websockets`를 설치하세요:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

If you don't want to use Pydantic models, you can also use **Body** parameters. See the docs for [Body - Multiple Parameters: Singular values in body](body-multiple-params.md#singular-values-in-body){.internal-link target=_blank}....
