## `PATCH`로 부분 업데이트하기 { #partial-updates-with-patch }

[HTTP `PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH) 작업을 사용해 데이터를 *부분적으로* 업데이트할 수도 있습니다.

이는 업데이트하려는 데이터만 보내고, 나머지는 그대로 두는 것을 의미합니다.

/// note | 참고

`PATCH`는 `PUT`보다 덜 일반적으로 사용되고 덜 알려져 있습니다.

그리고 많은 팀이 부분 업데이트에도 `PUT`만 사용합니다.

여러분은 원하는 방식으로 **자유롭게** 사용할 수 있으며, **FastAPI**는 어떤 제한도 강제하지 않습니다.

다만 이 가이드는 의도된 사용 방식이 대략 어떻게 되는지를 보여줍니다.

You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note

For more details, check Starlette's documentation for [testing WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions).

# WebSocket 테스트하기 { #testing-websockets }

같은 `TestClient`를 사용하여 WebSocket을 테스트할 수 있습니다.

이를 위해 `with` 문에서 `TestClient`를 사용하여 WebSocket에 연결합니다:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note

자세한 내용은 Starlette의 [WebSocket 테스트](https://www.starlette.dev/testclient/#testing-websocket-sessions) 문서를 확인하세요.

要使用表单，首先安装 [`python-multipart`](https://github.com/Kludex/python-multipart)。

确保你创建一个[虚拟环境](../virtual-environments.md)，激活它，然后再安装，例如：

```console
$ pip install python-multipart
```

///

/// note | 注意

自 FastAPI 版本 `0.113.0` 起支持此功能。🤓

## 表单的 Pydantic 模型 { #pydantic-models-for-forms }

你只需声明一个 **Pydantic 模型**，其中包含你希望接收的**表单字段**，然后将参数声明为 `Form`：
