大佬教程收集整理的这篇文章主要介绍了Arduino ESP8266 HTTPS 服务器如何安装 SSL 证书，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我使用 ESP8266WebServer 库在我的 NodeMCU ESP8266 板上制作了 http 服务器。我想将其转换为httpS服务器，所以我使用了ESP8266WebServerSecure库，购买了SSL证书并获得了3个文件：
certificate.cert
dv_ca.pem
private.pem
有人能解释一下我应该如何在我的服务器上安装它吗？当我尝试使用自生成的证书启动 https 服务器时，在我的代码下方，但使用 androID 应用程序连接它时出现问题（未找到 AndroID SSL 连接的信任锚点）。

代码来自 ESP8266 的示例。除测试目的外，更改证书。您可以从 Internet 获取证书或使用位于 @H_427_5@make-self-signed-cert.sh 的 ESP8266WiFi/examples/WiFihttpSServer 生成证书。在执行 @H_427_5@make-self-signed-cert.sh 之前，修改脚本。找到 your-name-here 并将其替换为您的姓名或组织名称。然后执行脚本。在执行结束时，将出现名为 key.h 和 x509.h 的新文件。证书代码位于两个新文件中。将它们复制并粘贴到 arduino 代码中。
