阿里云物联网管理SDK使用示例

概述

目前阿里云的绝大部分服务都提供了管理资源的Rest API，针对相应的API也做了SDK的封装，且版本也在不断的迭代更新。管理API SDK的统一GitHub地址链接。关于IoT SDK的使用，之前官方也给出了示例参考，但是该示例使用的SDK版本为5.0.0，且这个版本的SDK中没有DeleteProductRequest类的实现，下面演示使用目前最新版本:6.5.0关于产品的创建及删除操作，新建Topic间的消息路由关系、查询向指定Topic订阅消息的目标Topic操作，其它操作类似。

注意

当前阶段国内只有上海地区支持IoT服务，用户只需要根据需求替换AK及IoT的信息即可。删除产品的前提是产品中没有设备，管理门户目前删除产品需要短信验证码，直接使用SDK调用不需要验证码。
