Sie können einen „Closing“-Code verwenden, aus den <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">gültigen Codes, die in der Spezifikation definiert sind</a>.

### WebSockets mit Abhängigkeiten ausprobieren

Como isso é um WebSocket, não faz muito sentido levantar uma `HTTPException`, em vez disso levantamos uma `WebSocketException`.

Você pode usar um código de fechamento dos <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">códigos válidos definidos na especificação</a>.

///

### Tente os WebSockets com dependências

Se seu arquivo for nomeado `main.py`, execute sua aplicação com:

{!> ../../docs_src/websockets/tutorial002.py!}
```

////

/// info

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<a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">规范中定义的有效代码</a>。

///

### 尝试带有依赖项的 WebSockets

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```console
$ uvicorn main:app --reload

/// info

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">valid codes defined in the specification</a>.

///

### Try the WebSockets with dependencies

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

<mxfile host="65bd71144e">
    <diagram id="BkDNbdtn8_9fWQybnc8v" name="Page-1">
        <mxGraphModel dx="741" dy="1167" grid="1" gridSize="10" guides="1" tooltips="1" connect="1" arrows="1" fold="1" page="1" pageScale="1" pageWidth="1920" pageHeight="1200" math="0" shadow="0">
            <root>
                <mxCell id="0"/>
                <mxCell id="1" parent="0"/>

WebSocket で `HTTPException` を発生させることはあまり意味がありません。したがって、WebSocketの接続を直接閉じる方がよいでしょう。
