经过一番努力，我终于能够构建一个用Java实现的简单的HTTPS示例服务器，如下所示。它接受客户端连接并发回一段有关套接字信息的文本。所以到目前为止我有一个工作服务器示例；干净整洁。如何使其成为双向连接，以便客户端也能够以交互模式发送/接收信息？我应该如何实现后退和前进的步骤？
基本上，我希望在连接到服务器后在浏览器上显示这样的表单(这很简单；就像现在，我将发送与表单的 html 代码相对应的文本)。但我需要客户端将填写的数据发送回服务器。服务器会对这些原始数据进行一些处理，并将结果返回给客户端显示。
PS:如果您想测试该程序，请不要忘记创建 keystore 证书并提供以下信息。

最佳答案
您的表单还应包含 <BUTTON type = "submit"...>用于发送填写好的表格，以及 <FORM action="http://somesite..." method="post">让您确定地点和方式。浏览器处理客户端(验证除外 - 您需要一些 JavaScript 代码或等效代码)。
来自 http://www.w3.org/ 的 HTML 4 或 5 规范包含很多示例。
