## 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。

/// tip

域名这部分发生在 HTTPS 之前，由于这一切都依赖于域名和 IP 地址，所以先在这里提一下。

Der Client **vertraut** bereits der Entität, die das TLS-Zertifikat generiert hat (in diesem Fall Let's Encrypt, aber wir werden später mehr darüber erfahren), sodass er **verifizieren** kann, dass das Zertifikat gültig ist.
