reading JSON file

#Ensemble

Hi Guys,

I'm using the below so I can put JSON file in an object and read each property:

  d ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(JSONString3,,.list)
 S Job= list.jobGUID

but because the JSON starts and ends with [ ] my list is empty, and I had to remove them to get a good list.

So is there a way that I can handle this which having me removing those brackets each time, because I thought %ConvertJSONToObject to be able to handle this anyway?

FYI I'm running Ensemble 2014

 

[{"routeGuid":"531318d8-9967-445a-ae42-14e04244e0fb","sensorType":"MEMS TRIAXIAL","startDateTime":"2022-05-20T23:04:51.159Z","myProperty":0,"callbackHost":"https://vibra-api-dev.azurewebsites.net/api/sensors/vibration","collectionQuantity":1,"collectionInterval":0,"collectionTimeout":28140,"locationName":"Test Plant 1","locationGuid":"286c2dac-597d-41b0-8f6e-55f19fce9a9e","sensors":[{"equipmentName":"TestAsset 1","equipmentGuid":"ca62ff12-37fe-47a3-a315-95a4c011d835","componentName":"TestMOTORComponent 1","componentGuid":"3a291bf6-1ffd-4e14-b265-4b973c7660df","jobGUID":"0b955ee7-9a54-4b13-9af1-7019721faeab","sensorId":"MY0088","sampleRate":5000,"numberOfSamples":30000}]

Thanks

From your JSON-String, someone stripped off two chars at the end: "}]"

So if you add those chars, everything will be OK

d ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(JSONString3_"}]",,.list)
w list.GetAt(1).sensors.GetAt(1).jobGUID --> 0b955ee7-9a54-4b13-9af1-7019721faeab

what I sent is just a part of the full JSON as an example so it's not because it's missing part of it here is the full string, where I had to remove the brackets from beginning and end

read json <now, Cntrl-V here the above string, press enter>, then

w ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(json,,.list1) --> 1
w list1 --> 42@%Library.ListOfObjects
w list1.GetAt(1).sensors.GetAt(1).jobGUID --> 0b955ee7-9a54-4b13-9af1-7019721faeab

where is the problem?

Ok I see, I did add the GetAt(1).

Thanks Julius

To get all the jobGUIDs you need two loops:

f i=1:1:list1.Size f j=1:1:list1.GetAt(i).sensors.Size w list1.GetAt(i).sensors.GetAt(j).jobGUID,!
