Android从OceanConnect上获取数据
接口文档下载：https://developer.huawei.com/ict/cn/rescenter/CMDA_FIELD_OCEAN_CONNECT?developlan=Other
主要看第九章
第一步：Auth(鉴权)，获取accessToken。

} 第二步：查询设备历史数据
调用方法
GET
接口路径
https://server:port/iocm/app/data/v1.1.0/deviceDataHistory?deviceId={deviceId}&
gatewayId={gatewayId}&serviceId ={serviceId}&pageNo={pageNo}&pageSize
={pageSize}&startTime={startTime}&endTime={endTime}&property={property}&appId={appId}
官方api文档中有{}，但我觉得{}要去掉。
注意事项
携带头域信息
Header：
"app_key:{appId}"
"Authorization:Bearer {accessToken}"
Content-Type:application/json;
