Time handling and Json

I am having trouble formatting %Time to a JSON format. I have tried configuring the parameter "FORMAT" of my property but that didn't work. For some reason, it keeps putting a Z and the end of the time.

Property:

Property TimeCollected As %Time(FORMAT = "2");

Hi Community,

I have json equivalent persistent object in pjsonObj variable. Final JSON example below.

{
"Document": {
"FileExtension": "pdf",
"FileContent": "JVBERi0xLjUNCiW1tbW1DQo...(very large bsae64 string)"
}
}

Here FileContent field in json will contain converted base64 string of very large pdf(10pages). I need to submit this json as a payload to REST endpoint.

below code is working fine.

I have defined a class with a dynamic object property:

My class

The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):

Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1

Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.

$ZSTORAGE is set to -1.

FHIR Bulk Data and ndjson

Hi all,

I am testing asynchronous Bulk Data retrieve with a large EHR vendor. When I retrieve the bulk data, they are returning ndjson (CONTENT-TYPE of "application/fhir+ndjson; charset=utf-8"). If I attempt to process that content using JSON functions - I get

ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

For example, the following generates the error

s objArray={}.%FromJSON(quickStreamOut)

The error makes sense in that ndjson is not a valid json format (I assume at least).

JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

I have an issue where a Windows Reserved word, in my case CON, is causing an error when used as part of a JSON Get operation. In this case CON is the user identifier (the full identifier is CON.SURNAME) of a person and I am trying to read the employee record using a web service provided by the payroll system.

Is there a way I can get around this, some sort of encoding that would enable the inclusion of this identifier. I can't just change the identifier has it is used extensively across systems.

Parsing null values in JSON

Hello everyone,

I'm creating a REST API with InterSystems Ensemble.

I already have a POST route that parses JSON content into an object defined in a class.

To parse the JSON content, I'm using the JSONStreamToObject method in the Ens.Util.JSON class

Here is how I use it:

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this.

I am trying to find out how to count the number of elements within a dynamic abstract object and I am having some trouble using the size method.

Here is the code below:

The key value pairs are originally in JSON and I would have converted it in to an object for use.

I'm trying to set up VS Code for ObjectScript using the instructions found here. I've got both Cache 2018.1.2.309.0 and IRIS 2020.1.0.215.0. When I try to connect to either one of them the connection fails, and I get a notification in the bottom right corner that says "Unexpected token < in JSON at position 0". I've checked the JSON settings file that VS Code uses, and they're fine and formatted properly. All of the settings I've entered are correct.

Hello,

I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.

If you could point me to any information, that'd be great.

Thank you.

Hello

I am creating an import tool to convert a client's JSON data into IRIS classes. The sample file is over half a gig. I am copying the data into an instance of %Stream.FileCharacter;. My first few attempts worked fine. However I started getting an error thrown when I try to create a DynamicAbstractObject using the %FromJSON method. See the code below. The error code given is not in the documentation, at least not the doc that I was searching.

I had a challenge recently where I was asked to parse and iterate JSON to find a patient that has a forename = "Bill" and try to make the function that iterates through the code re-usable.

Being working in Healthcare there isn't much experience or demand for parsing JSON, as most of my work is HL7.

I took this on using the documentation and worked out a way to parse the JSON (see posts below for code and source data).

Hello,

We are working with a vendor who only accepts JSON as payload. We are currently still on Cache/HealthShare, not IRIS. Since we have to send Continuity of Care Documents, this raises issues with Long Strings (some CCDs can be quite large and in addition to that, they have to be b64-encoded which increases their size even more).

My question is: if we were to go on IRIS and use %JSON.Adapter, storing the encoded Stream in an object's Stream property, would calling %JSONExport() on this object produce the desired JSON? Or would we have to call %JSONExportToStream()?

What is the best way to create an HL7 message from JSON input file?

We have JSON file available with data required for building the HL7 message . I am trying to use a standard file/FTP Business service to pick up the file and convert the input %FileCharacterStream into a dynamic Object and use the stand JSON features to read /process the data and build the HL7 message.

Is there any other better way to do this? or any standard built-in functionality available in HealthShare?

Thanks you for your help

Hey Intersystems Community,

I have a Problem with the Session Handling in .csp.

I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.

After that the Web Service response is in JSON.

I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html.
Everything Works Fine with the session Handling via Cookie.
