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 [valid codes defined in the specification](https://tools.ietf.org/html/rfc6455#section-7.4.1).

///

### Try the WebSockets with dependencies { #try-the-websockets-with-dependencies }

Run your application:

<div class="termy">

```console
$ fastapi dev

В веб-сокете вызывать `HTTPException` не имеет смысла. Вместо этого нужно использовать `WebSocketException`.

Вы можете использовать код закрытия из [допустимых кодов, определённых в спецификации](https://tools.ietf.org/html/rfc6455#section-7.4.1).

///

### Веб-сокеты с зависимостями: проверка в действии { #try-the-websockets-with-dependencies }

Запустите приложение:

<div class="termy">

```console
$ fastapi dev

# 基准测试 { #benchmarks }

第三方机构 TechEmpower 的基准测试表明在 Uvicorn 下运行的 **FastAPI** 应用程序是 [可用的最快的 Python 框架之一](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7)，仅次于 Starlette 和 Uvicorn 本身（由 FastAPI 内部使用）。

但是在查看基准得分和对比时，请注意以下几点。

## 基准测试和速度 { #benchmarks-and-speed }

当你查看基准测试时，几个不同类型的工具被等效地做比较是很常见的情况。

具体来说，是将 Uvicorn，Starlette 和 FastAPI 一起比较（在许多其它工具中）。

但是在查看基準得分和對比時，請注意以下幾點。

當你查看基準測試時，常見到不同類型的多個工具被視為等同來比較。

具體來說，是將 Uvicorn、Starlette 和 FastAPI 同時進行比較（以及許多其他工具）。
