ESP8266 – WiFiServerSecure库 – WiFiServerSecure

位置导航: ESP8266库 / WiFiServerSecure库 / 本页

说明

通过WiFiServerSecure语句，我们可以建立WiFiServerSecure对象从而使用ESP8266建立支持HTTPS协议的物联网服务器。

语法

WiFiServerSecure server(port)

参数

– port: 此参数用于设置服务端口号。(类型:uint16_t)

返回值

无

示例程序

为了演示本实例程序的运行结果，我在这里使用基于Chrome内核的Microsoft Edge浏览器来进行示例程序操作演示。

请务必注意：本示例程序所使用的证书和密钥只能用于测试使用。您在自己搭建ESP8266物联网项目时，需要自行建立证书密钥而不要使用本示例中的证书和密钥。

当您将以下示例程序中的WiFi连接信息修改并且将本示例程序上传ESP8266开发板后，开发板随即会自动连接WiFi。WiFi连接成功后，您将可以从串口监视器获取当前ESP8266开发板的IP地址。此时，ESP8266已经成功建立了支持HTTPS协议的网络服务器。您可以通过ESP8266的IP地址来访问该网络服务器。

假设您的ESP8266开发板IP地址是192.168.0.111。那么接下来您可以通过浏览器输入

https://192.168.0.111。

注意一定要在ESP8266的IP地址前面加上“https//”。这一操作将会让浏览器通过https协议访问ESP8266所建立的服务器。如果不输入这一信息，浏览器默认会使用http协议而不是https协议。也就达不到我们想要实现的效果。（如下图所示）

当您如上图所示输入完IP地址后，接下来请按下回车键。您将在浏览器中看到如下警告信息。这很正常，因为ESP8266的服务器证书不是CA颁布的证书，所以浏览器会警告我们，它无法确定ESP8266服务器的身份信息。请忽略这一警告信息，并按照下图所示，点击按钮。

接下来您将看到如下图所示的信息。该信息正是详细说明为何无法验证ESP8266服务器身份的原因。我们需要继续忽略这一警告信息，并按照下图所示，点击链接。

如下图所示，您将看到浏览器中出现了“Hello from ESP8266”信息。这一信息是由ESP8266服务器发来的。说明我们的ESP8266服务器已经可以通过HTTPS协议进行数据通讯了。

关于如何使用WiFiServerSecure来建立对象这一操作，请见以下程序中的高亮语句部分。
