天猫精灵接入 并调用OneNet接口控制ESP8266（NodeMcu开发板）

• 准备工作
• NodeMcu开发板
• 天猫精灵（我用的是方糖89一个）
• 服务器（找个自己熟悉的都可以 我用的是本地搭建的Tomcat服务器）
• OneNet账号 

控制过程    天猫精灵  -》 AliGenie平台   -》  Tomcat服务器   -》 OneNet  -》  NodeMcu  -》你要控制的设备

OAuth2授权部分  :

 

首先就是OAuth2认证部分 天猫精灵通过H5页面的账号去调用你的服务器校验是否正确 正确就返回Token相关数据 不正确就返回错误 这部分由于需要校验账号 就需要使用数据库部分 但是我通过网上其他代码简化了下  砍掉了数据库和校验的部分 直接返回Token 就是AliGenie请求过来后我们不校验账号 你说什么都是对的 

代码分为几个类

• Authorize.java //账户授权连接部分 Servlet类
• GetToken.java //获取token  这一步其实就是校验账户和授权是否过期  Servlet类
• ReadMessage.java  //AliGenie调用  控制我们NodeMcu就会通过这个接口告诉我们 Servlet类
• AliGenieBean.java  //bean类  把获取到的json转换成对象 Bean类

 

不知道说什么了  直接上代码吧
