因為這是 WebSocket，拋出 `HTTPException` 並沒有意義，因此我們改為拋出 `WebSocketException`。

你可以使用規範中定義的[有效關閉代碼](https://tools.ietf.org/html/rfc6455#section-7.4.1)之一。

### 用依賴試用 WebSocket { #try-the-websockets-with-dependencies }

執行你的應用：

<div class="termy">

```console
$ fastapi dev

{* ../../docs_src/websockets_/tutorial002_an_py310.py hl[68:69,82] *}

/// info | 정보

WebSocket이기 때문에 `HTTPException`을 발생시키는 것은 적절하지 않습니다. 대신 `WebSocketException`을 발생시킵니다.

명세서에 정의된 [유효한 코드](https://tools.ietf.org/html/rfc6455#section-7.4.1)를 사용하여 종료 코드를 설정할 수 있습니다.

### 종속성을 가진 WebSockets 시도해보기 { #try-the-websockets-with-dependencies }

애플리케이션을 실행합니다:

<div class="termy">

```console

/// info | 情報

これはWebSocketであるため、`HTTPException` を発生させることはあまり意味がありません。代わりに `WebSocketException` を発生させます。

クロージングコードは、[仕様で定義された有効なコード](https://tools.ietf.org/html/rfc6455#section-7.4.1)の中から使用することができます。
