      第三版 HTTP+MQTT

    西电网页认证上网

    直接连接公网mqtt

    手机发消息,esp8266向电脑打印出来

    arduino 不支持中文汉字打印输出

    上面是 西电网页认证后返回的网页源码

    下面是从MQTT服务器接收的数据

    至此初步完成ESP8266网页认证上网模式。

    下一步,将固定的post请求信息换成网页输入可以配置的

    1. 网页输入wifi名(网页认证模式的wifi),无密码
    2. 网页输入自己的学号和密码
    3. 自动截取给网页服务器返回的 http请求和参数格式
    4. 由此配置ESO8266来网页认证上网

    关于网页服务器建立,返回页面,手动输入配置信息的教程看 ESP8266路由文件教程。
