We recently had an issue where we weren't able to parse a JSON HTTP request, but the issue went by unnoticed. We also did not have a trace of what the raw HTTP request was that we couldn't parse. I'm looking at improving our this by: Tracing the raw request using $$$TRACE
Raising an alert which will hit our Ens.Alert router which will compose and send an email
Hi, I'd like to ask if it is possible to use an arbitrary JSON as a DTL source. Can the IRIS DTL editor parse JSON of arbitrary structure and display it as a tree?
I am playing around with trying to make an Epic REST API call from an operation, and from what I understood because the request has to be sent as POST, I need to send the request as JSON. However when I try taking the request and running %ToJSON against it for the payload to be created I am getting an error...
I had attempted to create a REST Operation before but did not have success. As I am going through the Tutorials and Documentation everything references REST services, but I have a case where I want to create a REST Operation that makes Epic API calls against Interconnect. I have done SOAP operations before and we currently have one in our Production Namespace, but from what I understand SOAP has the wsdl which defines al the structures and etc, where REST does not.
I'm trying to figure out why I'm unable to iterate through a dynamic array and access the nested objects.
Using the NHS PDS FHIR API in the NHS sandbox environment, I'm querying the PDS endpoint using a sample NHS Number to retrieve a patient's demographics. My Business Operation reads the response data and passes it back to my Business Process where I intend on iterating through certain nested objects. The data present in these nested objects will decide what happens next in the process.
As it says in documentation %ZEN.Auxiliary.jsonProvider been deprecated. We been using it's functions like %ConvertJSONToObject, WriteJSONFromObject etc. Is there any replacement?
How many times do we find ourselves rebuilding, copy-pasting, adapting, Business Operations that make calls to REST services, and only adapting one or another part of the final code. This is annoying a lot. To resolve this our inconvenience, I present to you Interopway REST, a set of classes (a micro framework) that allows us to just add Business Operation to Production and use it.
Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?
Thank you very much for reading the doubt and above all thank you very much for answering.
Given the following use case:
If we have a Destination Service that through a HTTP GET by REST gives us a certain JSON response, where it should be noted that it is a list of objects where each object in the list does NOT have a key:
Being a programmer nowadays is basically the geek version of being a polyglot. Of course, most of us here, in the InterSystems Community, “speak ObjectScript”. Howeever, I believe this wasn’t the first language for many people. For instance, I had never heard about it prior to getting the appropriate training at Innovatium.
I'm trying to sign some custom JWT with x.509 certs but running into a problem with the signed JWT containing some information I need in the JOSE header.
Is there a way to get the "X5C:[]" header included in the signed JTW? IS this as easy as setting something like the following
I am new to ensemble development, Can anyone share me few basic Concepts which will be helpful for Converting JSON message to other message types like HL7,XML
Class pbarton.test Extends (%RegisteredObject, %JSON.Adaptor)
{
Property Version As %String;
}
The Version property could be either a string or a number in the JSON source data. If it's a string, importing it will succeed. If it's a number, importing fails.
I am trying to read binary data from HTTP Request Stream and build a Dynamic Object with multiple properties. I am getting MAXSTRING error with this code:
Saw the other day an article with the usage of the %ZEN package when working with JSON and decided to write an article describing a more modern approach. At some recent point, there was a big switch from using %ZEN.Auxiliary.* to dedicated JSON classes. This allowed to work with JSONs more organically.
Thus, at this point there are basically 3 main classes to work with JSON:
%Library.DynamicObject - provides a simple and efficient way to encapsulate and work with standard JSON documents. Also, there is a possibility instead of writing the usual code for creating an instance of a class like
set obj = ##class(%Library.DynamicObject).%New()
it is possible to use the following syntax
set obj = {}
%Library.DynamicArray - provides a simple yet efficient way to encapsulate and work with standard JSON arrays. With arrays you can use the same approach as with objects, meaning that yu can either create an instance of the class
set array = ##class(%DynamicArray).%New()
or you can do it by using brackets []
set array = []
%JSON.Adaptor is a means for mapping ObjectScript objects (registered, serial or persistent) to JSON text or dynamic entities.
Hello, I want to show a fellow DC member how to convert JSON file into HL7 message. I personally do not work with HL7. I set up a production with EnsLib.File.PassthroughService. It passes Ens.StreamContainer to BPL process. I call a DTL to transform StreamContainer to HL7 message. I run into an error:
ERROR <Ens>ErrBPTerminated: Terminating BP JSON2HL7 # due to error: ERROR #5035: General exception Name 'Parsing error' Code '3' Data '' > ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''
InterSystems IRIS versions 2022.2 and newer feature the ability to authenticate to a REST API using JSON web tokens (JWTs). This feature enhances security by limiting where and how often passwords transfer over the network in addition to setting an expiration time on access.
The goal of this article is to serve as a tutorial on how to implement a mock REST API using InterSystems IRIS and lock access to it behind JWTs.
InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.
Examining FHIR profile validation with InterSystems FHIR server. FHIR profiles is a very useful feature of FHIR standard that helps an organization or solution to establish constraints to a very disperse FHIR standards that are relevant to a particular business solution. Learn more on FHIR profiles.
I created a very simple FHIR profile with the following JSON:
The idea is that you can post a bundle to a FHIR server with a set of resources. And you can send it as a transaction, so only all the resources will be published or neither.
E.g. I send a bundle of two resources: patient and its observation.
The observation resource should reference an existing patient. But it probably doesn't exist yet on the server and goes within the same bundle.
For this purpose there is a way to have a temporary id in the bundle, to let resources reference ids.
Once again I had a challenge that costed me some time and a lot of testing to reach the best solution. And now that I've managed to solve it, I'd like to share a little bit of my knowledge.
What happened?
In a namespace there were a lot of similar classes, so to make them simpler there were a superclass with comon properties. Also, there are relationships between them. I had to export one of them to JSON, but I couldn't change the superclasses, or I would break down the flow of many other integrations.
