功能描述
获取空间汇总数据（Get Channel Feed Summaries）接口用于从指定空间（channel）中的所有传感器字段读取汇总数据。此方法可以返回JSON或CSV对象。每个汇总数据记录由每小时的总和、平均值、记录数量、标准差、每个字段的最大值和最小值组成。
请求地址
返回JSON对象:
https://webapi.ubibot.cn/channels/CHANNEL_ID/summary.json?parameters
返回CVS文件格式:
https://webapi.ubibot.cn/channels/CHANNEL_ID/summary.csv?parameters
将以上URL中的CHANNEL_ID替换成空间编号。
请求方式
GET
请求参数
| 名称 |
类型 |
是否必须 |
描述 |
