Ou você pode ter qualquer outra forma de comunicar com o endpoint WebSocket.

Mas para este exemplo, usaremos um documento HTML muito simples com algum JavaScript, tudo dentro de uma string longa.

Esse, é claro, não é o ideal e você não o usaria para produção.

Na produção, você teria uma das opções acima.

import org.codelibs.fess.suggest.request.Response;

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。

但是，在本示例中，我们将使用一个非常简单的HTML文档，其中包含一些JavaScript，全部放在一个长字符串中。

当然，这并不是最优的做法，您不应该在生产环境中使用它。

在生产环境中，您应该选择上述任一选项。

但这是一种专注于 WebSockets 的服务器端并提供一个工作示例的最简单方式：
