#JSON

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:

IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) Tue Apr 30 2024 16:06:39 EDT [HealthConnect:7.2.0-1.r1]

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.

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:

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 a 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 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?

Good morning, 🙂

I would like to ask a question, which has to do with how to manage %GlobalCharacterStream representing JSONS.

Thank you for reading this question, thank you for your help, and thank you for your time and attention.

Specifically, in a certain Process, we were querying 2 Operations, whose response we were converting to a Property called "informesAutorizadosRangoFechas" (reportsAuthorizedInRangeDates) which is %GlobalCharacterStream whose content is a JSON with the same structure.

Is there a way to use the %JSON.Adaptor to project readable JSON when a property is defined as a %Integer but with a DISPLAYLIST ?

Hi community,

I'm calling to a API that it is retrieving the content of a file as Content of response. I'm catching the binary but I need to convert this Stream to a Base64 string.

I'm trying to convert a %Stream.GlobaBinary to a Base64 string using the following code, but it doesn't work.

You may have heard about our mg-dbx-napi interface for IRIS which provides insanely fast access from Node.js. If you've been following recent developments in the server-side JavaScript world, you'll be excited to know that mg-dbx-napi also works with Bun.js, the latter proving to be significantly faster than Node.js for many/most purposes.

Of course, if you're a Node.js user, you'll probably wonder how mg-dbx-napi compares with the Native API for Node.js that is included with IRIS.

JSON is a lightweight data interchange format for representing and exchanging data between a server and a web application. Its popularity has led to its widespread use in applications based on InterSystems technology, as well as demand for a converter that transforms globals to JSON and back. Therefore, @Evgeny Shvarov suggested developing Global->JSON->Global converter. Implementing such a converter is important to ensure interoperability, simplify data exchange, support web services, and provide a standardized approach to data representation across different software ecosystems. This article, the second in the "Implemented Ideas" series, focuses on several projects created by the legend of InterSystems Developer Community @Robert Cemper that deal with this task:

• GlobalToJSON-Compact
• GlobalToJSON-Efficient
• GlobalToJSON-Academic
• GlobalToJSON-embeddedPython
• GlobalToJSON-ePython-pure
• GlobalToJSON-XLA
• JSONfile-to-Global.

We have JSON type data in a Dynamic Object. Is there a simple way to export / dump that data to a delimited string or file?

e.g.

Results={"ClassA":{"ClassName":"ClassA","ACount":367191880,"BCount":367191880,"CurrentDiff":0,"PreviousDiff":0,"ReportDate":"2024-03-02 00:00:00"}
"ClassB":{"ClassName":"ClassB","ACount":5352149227,"BCount":5352149227,"CurrentDiff":0,"PreviousDiff":0,"ReportDate":"2024-03-02 00:00:00"}}

I am sending an httpRequest from ObjectScript to a python server. I am not receiving a response in OS

OS config On the client side

// Create an HTTP request object
Set httpRequest = ##class(%Net.HttpRequest).%New()

// Set the server URL
Set httpRequest.Server = "http://127.0.0.1:8080"

// Set content type to JSON
Set httpRequest.ContentType = "application/json"

There is an interesting new feature in the recently announced 2024.1 preview, JSON_TABLE. JSON_TABLE is one of a family of functions introduced by the 2016 version of the SQL Standard (ISO Standard, published in early 2017). It allows for JSON values to be mapped to columns and queried using SQL. JSON_TABLE is valid in the FROM clause of some SQL statements.

The syntax of JSON_TABLE is quite large, allowing for exceptional conditions where the provided JSON values don't match expectations, nested structures and so on.

Hi all,

We have a class response inherited from %JSON.Adaptor with the following properties, also dependent classes:
