　　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。
