브라우저 클라이언트로 데이터를 스트리밍하려면 **Server-Sent Events**(SSE)를 사용할 수 있습니다.

이는 [JSON Lines 스트리밍](stream-json-lines.md)과 비슷하지만, 브라우저가 기본적으로 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)를 통해 지원하는 `text/event-stream` 형식을 사용합니다.

## Server-Sent Events란 { #what-are-server-sent-events }

 * is a basic description of the algorithm. For a more complete description
 * we recommend reading the section on Access Control in Keith Brown's
 * "The .NET Developer's Guide to Windows Security" (which is also
 * available online).
 * <p>
 * Direct ACEs are evaluated first in order. The SID of the user performing
 * the operation and the desired access bits are compared to the SID

# WebSockets { #websockets }

**FastAPI**で[WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)が使用できます。

## `websockets`のインストール { #install-websockets }

[仮想環境](../virtual-environments.md)を作成し、それを有効化してから、「WebSocket」プロトコルを簡単に使えるようにするPythonライブラリの`websockets`をインストールしてください。

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets クライアント { #websockets-client }

* その後、`response` を返す前にさらに `response` を変更することもできます。

**Pydantic v2**의 이 기능 덕분에 API 문서는 더 **정밀**해지고, 자동 생성된 클라이언트와 SDK가 있다면 그것들도 더 정밀해져서 더 나은 **developer experience**와 일관성을 제공할 수 있습니다. 🎉

## 스키마를 분리하지 않기 { #do-not-separate-schemas }

이제 어떤 경우에는 **입력과 출력에 대해 같은 스키마를 사용**하고 싶을 수도 있습니다.
