关于使用Predix Tool Kit上传和查询timeseries数据

首先需要一个predix账号，然后去https://www.predix.io/catalog/services创建一个UAA(User Account and Authentication)和Time Series服务，创建完以后你需要下载一个Application，通过这个Application来查询UAA和Timeseries里面的predix-zone-id等参数信息：

下载一个Application:git clone  https://github.com/PredixDev/predix-nodejs-starter.git

下载完有个manifest.yml文件，需要修改：

services下面填入创建的服务名称。

然后登陆cf账号以后，在predix-nodejs-starter目录下使用cf push命令将Application传到云端。

成功以后 cf env application-name查询UAA和Timeseries相关参数：

然后还需要在console里面打开Open Service Instance查找你的UAA URL以登陆predix tool kit

准备工作做好以后介绍使用Predix-Tool-Kit:进入https://predix-toolkit.run.aws-usw02-pr.ice.predix.io/

然后完成Create Client ID，Get Client ID，Update Client ID：

Update Client ID的作用是给发送和接收Timeseries数据权限，加上三段：

timeseries.zones.<your-timeseries-zone-id>.ingest

timeseries.zones.<your-timeseries-zone-id>.query

timeseries.zones.<your-timeseries-zone-id>.user

切换到API Explorer,在Time series Ingest下添上predix-zone-id,Open Socket发送TimeSeries格式数据：

202表示发送成功。

然后在Time Series查看云上的数据：
