IoTチームのために、何かお役にたてば、、とブログだけ。。
まず、Python2の復習。
エスケープシーケンスを使うのでメモ掲載、
改行とか。表は下記参考に。
(figure1)
で、さて、まずは、Deviceの登録をします。
マニュアルによると、「Create」から。。。。。
Linuxでのコマンドは。下記。
ID、Passをそのまま載せているけど悪さしないでね＞見ている人
デバイス名は「HelloWorldDevice2017/01/24」にとりあえず。
==================
(#1)
curl -v -u yoshihara20161226:A******6 \
-H ‘Accept: application/vnd.com.nsn.cumulocity.managedObject+json; charset=UTF-8; ver=0.9’ \
-H ‘Content-type: application/vnd.com.nsn.cumulocity.managedObject+json; charset=UTF-8; ver=0.9’ \
-X POST \
-d ‘{“c8y_IsDevice”:{},”name”:”HelloWorldDevice2017/01/24“}’ \
https://iot05.cumulocity.com/inventory/managedObjects
さて、入ってみましょう！
https://iot05.cumulocity.com/
右上メニューからDeveice Managementをクリック
(figure 2)
connectionができれば、簡単に「dvice登録」されました！
ALLDeveicesをみると、、「HelloWorldDevice2017/01/24」が登録されてます。
で、デバイスをクリックすると、、
デバイスのInfo画面がでます。。。
右下に下がって、そこにデバイスIDが割振りされます。
これを使って、RESTで送ると、飲み込んでくれる仕組みです。
さて、次にwebでdeviceのIDを「デバイスID」に設定して、
pythonファイルを作成します。。。。
==================
ID=31124 ＜＝＝＝＝これが私のデバイスのID！！！
==================

print “————————–\\”
cmd1 = “curl -v -u yoshihara20161226:A******6 “
cmd2 = “-H ‘Accept: application/vnd.com.nsn.cumulocity.measurement+json; charset=UTF-8; ver=0.9’ “

cmd10 = “https://iot05.cumulocity.com/measurement/measurements/”
os.system(cmd1+cmd2+cmd3+cmd4+cmd5+cmd6+cmd7+cmd8+cmd9+cmd10)
コマンドファイルができたら、送ってみます！！Pythonで実行！！

最後に、周期的やらせるため、crontabを設定。
あとは様子見。。。。。
