# WebSockets

您可以在 **FastAPI** 中使用 [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)。

## 安装 `WebSockets`

首先，您需要安装 `WebSockets`：

```console
$ pip install websockets

---> 100%
```

## WebSockets 客户端

### 在生产环境中

在您的生产系统中，您可能使用现代框架（如React、Vue.js或Angular）创建了一个前端。

要使用 WebSockets 与后端进行通信，您可能会使用前端的工具。

或者，您可能有一个原生移动应用程序，直接使用原生代码与 WebSocket 后端通信。

或者，您可能有其他与 WebSocket 终端通信的方式。

        assertEquals(0, ((org.codelibs.fess.crawler.client.http.RequestHeader[]) initParamMap.get("requestHeaders")).length);
        assertEquals("Mozilla/5.0 (compatible; Fess/98.76; +http://fess.codelibs.org/bot.html)", initParamMap.get("userAgent"));
        assertEquals(0, ((Authentication[]) initParamMap.get(HcHttpClient.AUTHENTICATIONS_PROPERTY)).length);

        requestBody.put("name", NAME_PREFIX + "WebConfig");
        requestBody.put("urls", urls);
        requestBody.put("included_urls", includedUrls);
        requestBody.put("user_agent", "Mozilla/5.0");
        requestBody.put("depth", 1);
        requestBody.put("num_of_thread", 1);
        requestBody.put("interval_time", 1000);
        requestBody.put("boost", 100);
        requestBody.put("available", true);

You can use <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a> with **FastAPI**.

## Install `WebSockets`

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

# WebSocket

**FastAPI**で<a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSocket</a>が使用できます。

## `WebSockets`のインストール

まず `WebSockets`のインストールが必要です。

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSocket クライアント

### 本番環境

本番環境では、React、Vue.js、Angularなどの最新のフレームワークで作成されたフロントエンドを使用しているでしょう。
