먼저 코드를 그냥 사용해서 어떻게 동작하는지 보고, 그다음에 무슨 일이 일어나는지 이해하러 다시 돌아오겠습니다.

[`python-multipart`](https://github.com/Kludex/python-multipart) 패키지는 `pip install "fastapi[standard]"` 명령을 실행하면 **FastAPI**와 함께 자동으로 설치됩니다.

하지만 `pip install fastapi` 명령을 사용하면 `python-multipart` 패키지가 기본으로 포함되지 않습니다.

由于这是一个 WebSocket，抛出 `HTTPException` 并不是很合理，而是抛出 `WebSocketException`。

您可以使用[规范中定义的有效代码](https://tools.ietf.org/html/rfc6455#section-7.4.1)。

### 尝试带有依赖项的 WebSockets { #try-the-websockets-with-dependencies }

运行你的应用程序：

<div class="termy">

```console
$ fastapi dev

/// tip

You could use the same technique to extend the JSON Schema and add your own custom extra info.

For example you could use it to add metadata for a frontend user interface, etc.

///

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.
