## 创建 `websocket`

在您的 **FastAPI** 应用程序中，创建一个 `websocket`：

{* ../../docs_src/websockets/tutorial001.py hl[1,46:47] *}

/// note | 技术细节

您也可以使用 `from starlette.websockets import WebSocket`。

**FastAPI** 直接提供了相同的 `WebSocket`，只是为了方便开发人员。但它直接来自 Starlette。

///

## 等待消息并发送消息

在您的 WebSocket 路由中，您可以使用 `await` 等待消息并发送消息。

{* ../../docs_src/websockets/tutorial001.py hl[2,6:38,41:43] *}

## `websocket` 생성하기

**FastAPI** 응용 프로그램에서 `websocket`을 생성합니다:

{* ../../docs_src/websockets/tutorial001.py hl[1,46:47] *}

/// note | 기술적 세부사항

`from starlette.websockets import WebSocket`을 사용할 수도 있습니다.

**FastAPI**는 개발자를 위한 편의를 위해 동일한 `WebSocket`을 직접 제공합니다. 하지만 이는 Starlette에서 가져옵니다.

Und die Anrufe an den Client sind ebenfalls normale Anrufe, die nicht `await` verwenden.

Dadurch können Sie `pytest` ohne Komplikationen direkt nutzen.

Sie könnten auch `from starlette.testclient import TestClient` verwenden.

## Дополнительные данные OpenAPI { #openapi-extra }

Когда вы объявляете *операцию пути* в своём приложении, **FastAPI** автоматически генерирует соответствующие метаданные об этой *операции пути* для включения в схему OpenAPI.

/// note | Технические детали

В спецификации OpenAPI это называется <a href="https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object" class="external-link" target="_blank">Объект операции</a>.

Es war eines der ersten Beispiele für **automatische API-Dokumentation**, und dies war insbesondere eine der ersten Ideen, welche „die Suche nach“ **FastAPI** inspirierten.

    `--no-cache-dir` é apenas relacionado ao `pip`, não tem nada a ver com Docker ou contêineres.

    ///

    A opção `--upgrade` diz ao `pip` para atualizar os pacotes se eles já estiverem instalados.

```bash
helm install --set persistence.enabled=false minio/minio

If a Persistent Volume Claim already exists, specify it during installation.
