#JSON

12

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write.

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

Long JSON values

I have JSON object which contains file references. I need to replace the file reference with base64 encoded file which is up to 10MB.

I tried the following but it did not work as expected:

0 9
0 86

I have an API that does not have all the data. Like it is truncated. Magic number of characters seems to be 163,280

I do an <assign>

context.RawBundle=##class(%DynamicObject).%FromJSON(context.FHIRResponse.Body)

The error does not happen when the response is < 163,280 chars. And when < 163,280 chars, it is a complete FHIR Bundle. Have anyone experienced this? If so, what is the resolution?

I am working on JSON and want to be prepared to handle large Objects. I try this code:

ClassMethod MaxLen() As %Status

{

set longStr=""

for i=1:1:$SYSTEM.SYS.MaxLocalLength() { set longStr = longStr_"x" }

write "Maximum string length = "_$LENGTH(longStr)

;

set longObject = {"a":(longStr),"b":(longStr)}

set file=##class(%File).%New("/tmp/longObjectFile.txt")

do file.Open("WSN")

do longObject.%ToJSON(file)

do file.Close()

;

do file.Open("RS")

HI,

I'm migration an existing integration to InterSystems. The upstream (external) system calls a JSON web service hosted in the interface engine, which converts the JSON data received to an HL-7 messages to send to the downstream system. I'm looking for direction and example of how to do the equivalent in InterSystems, so the the upstream system only has to modify the URL of the web service they call.

I suppose in IS we'll need to create a business service that is a JSON web service? How to access the JSON data (parameters in the web service call) in the Transformation?

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

I use a swagger file and ##class(%REST.API).CreateApplication to create the rest api.

There is an interesting post: https://community.intersystems.com/post/download-file-rest-api-operation, but it is code, not a swagger configuration. disp.cls returns always a header content : application/json that of course fails as I am not always returning a json

I can not figure out what to put in swagger. Some examples I tried:
