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.

Over the past year or so, my team (Application Services at InterSystems - tasked with building and maintaining many of our internal applications, and providing tools and best practices for other departmental applications) has embarked on a journey toward building Angular/REST-based user interfaces to existing applications originally built using CSP and/or Zen. This has presented an interesting challenge that may be familiar to many of you - building out new REST APIs to existing data models and business logic.

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:

So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.

There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.

Hello everyone,

I created a Class with this 3 properties

Class TestDynamic Extends (%RegisteredObject, %XML.Adaptor)
{

Property number As %xsd.string;

Property exam As %xsd.string;

Property result As list Of %DynamicObject;

}

I'm adding objects to list normally

set objTest=##class(TestDynamic).%New()
set objDynamic={"field":"value"}
do objTest.result.Insert(objDynamic)

But when i use this method to convert to JSON

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.

Let's imagine if you would like to write some real web application, for instance, some simple clone of medium.com. Such sort of application can be written using any different language on the backend side, or with any framework on the frontend side. So many ways to do the same application, and you can look at this project. Which offers a bunch of frontends and backends realizations for exactly the same application. And you can easily mix them, any chosen frontend should work with any backend.

Let me introduce the same application realization for InterSystems IRIS on a backend side.

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).

Basic JSON Compare

Hi Dev Community

I thought i would share a little method I knocked together to traverse and compare 2 JSON objects for basic equivilance. I'm currently working on some data migration, and wanted a basic sanity check to validate that the JSON output is basically equivliant between the old and new, excluding a few things like timestamps.

It's a basic little recurvsive method, that will bubble up any differences over a nested structure. It's very low tech, as that's all I need it to do, but I thought it might be useful for others?

Hi All

It's been 6 weeks since my original article sad
- - - - -but I have been busy on this project

I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago.
Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail.
Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly.
And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit.
