Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass

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()?

Is there any way that I can check the native type of an object script variable? (similar to the typeof check in javascript)

I see that the DynamicArray class uses the type of the variable for its output, I would like to do something similar when I receive a value as an argument to my method.

USER>s var1 = 123 //No quotes, number type

USER>s var2 = "123" //quotes, string type

Recently i've been using Restforms2 to create a CRUD API for a project. But it lacks some advanced functionality that we need, so we have created a production with a REST WS which handles those advanced methods. That works great but there's a drawback, it does not have authentication.

I would want to use the same authentication method as Restforms2 which is a basic auth using IRIS users and passwords.

Hi,

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.

Backport %JSON.* to Caché

Attention:

This is a coding example working on Caché 2018.1.3
It will not be kept in sync with new versions 
It is also NOT serviced by InterSystems Support !

Full backport from IRIS for Windows (x86-64) 2020.1 (Build 215U) Mon Mar 30 2020 20:14:33 EDT

IRIS brought us an excellent %JSON.Package
It is an essential component of the Project Manager (ZPM)
This backport makes it available also in Caché and builds a base to eventually backport also ZPM.

Hello...

I need to convert a array (JSON) in a List Of String. I think, there is some method that does it directly.

Something like that:

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map frm %Library.Array instance to %Library.ListOfDataTypes

I have reading about this but I don't found some trick to help me.

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.

Hi guys,

How do you deal with underscore characters when using jsonProvider and exporting or importing ?

for example:

USER>s jsonString="{""what"":""1"",""up"":""2"",""test_test"":""3""}"
 
USER>set status = ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(jsonString,,.outputObj)
 
USER>w outputObj.what
1
USER>w outputObj.up
2
USER>w outputObj.test_test
 
W outputObj.test_test
^
<UNDEFINED> *test

we found out that we can access it like this, but not sure if it's the recommended method-

GlobalToJSON-embeddedPython-pure

I have created a package to export a Global into JSON object file and to re-create it by reloading from this file
embeddedPython refers to the new available technologies. It should be understood as a learning exercise of
how to handle the language interfaces. Only Global nodes containing data are presented in the generated JSON file.
Differently from the previous example, this one is using embedded Python only, no ObjectScript. Therefore PURE

Hello All,

I am compiling a REST Operation to call our hospital Administration system, following tutorials around the REST API's etc. First time we have integrated like this so not much knowledge around our hospital - hoping someone on here can help.

I have been using the JSONStreamToObject Method which is working as i expected, apart from trying to get a specific item in the example JSON Response as follows:

{"test":"abc","name":[{"use":"usual","family":"Matest","given":["Mia"]}]}

I'm revisiting some older projects that can benefit from the new JSON support and dynamic object capabilities in 2016.1 FT / 2016.2 FT. (Particularly, some of the really new features in the latest 2016.2 FT.)
For the particular thing I'm working on, it would be very handy to be able to merge objects, similarly to https://api.jquery.com/jquery.extend/. The closest thing I've found so far (in 2016.2 only) is:

Set o1 = {"a":1,"c":2}, o2 = {"b":1,"c":1}
Write "o1: ",o1.$toJSON(),!

Hello, I tried to convert HL7 message to JSON in a business process and I got errors. Has anybody converted HL7 to JSON? Are certain characters not allowed in JSON?

I just tried to set a property to quote request.RAWContent and quote. I will try to put example in GitHub and share here later.

Hello everyone!
I have to build a REST service that receives a POST HTTP-request, collect a file from that request in the Form data and then send it in another HTTP Post request through Form Data. However I can't really seem to send the file, and I do not know where it has gone wrong. All I am getting told is that no file is being received from my HTTP Post request. I am reaching the REST Service I am supposed to send the request to, but nothing is being sent.

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 ''

The code is in this GitHub repo:

most of my jSON data is single words, but when it comes to sending chunks of a memo/email via JSON, that totally different

which is the correct conversion process to prepare data ready to insert into the data part of a JSON string so that all problem characters are converted

JSON of course crashes if you use the wrong format of quotes (single or double) and you ned up having to use &QUOT and \' to get around that but is there a simple call to something that will just take care of preparing the data from the JSON string both on the inward and outward part of JSON

In this article we are going to see how we can use the WhatsApp instant messaging service from InterSystems IRIS to send messages to different recipients. To do this we must create and configure an account in Meta and configure a Business Operation to send the messages we want.

Let's look at each of these steps in more detail.

Setting up an account on Meta

This is possibly the most complicated point of the entire configuration, since we will have to configure a series of accounts until we can have the messaging functionality.
