域可以被安全地验证并自动生成证书。 这还允许自动更新这些证书。

我们的想法是自动获取和更新这些证书，以便你可以永远免费拥有**安全的 HTTPS**。

## 面向开发人员的 HTTPS

这里有一个 HTTPS API 看起来是什么样的示例，我们会分步说明，并且主要关注对开发人员重要的部分。


### 域名

第一步我们要先**获取**一些**域名(Domain Name)**。 然后可以在 DNS 服务器（可能是你的同一家云服务商提供的）中配置它。

你可能拥有一个云服务器（虚拟机）或类似的东西，并且它会有一个<abbr title="That isn't Change">固定</abbr> **公共IP地址**。

在 DNS 服务器中，你可以配置一条记录（“A 记录”）以将 **你的域名** 指向你服务器的公共 **IP 地址**。

这个操作一般只需要在最开始执行一次。

            buffer.putInt(4);
            buffer.putInt(1024);

            // When
            fileFsSizeInfo.decode(buffer.array(), 0, 24);

            // Then - multiple calls should return same values
            assertEquals(2000L * 4 * 1024, fileFsSizeInfo.getCapacity());
            assertEquals(2000L * 4 * 1024, fileFsSizeInfo.getCapacity());
            assertEquals(1000L * 4 * 1024, fileFsSizeInfo.getFree());
