#JSON

12

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

Hi all,

We faced a problem where we would like to map a $lb object to its corresponding data model structure in order to later on export it as JSON.

So imagin that we have something like this that actually maps to a persistent table with its structure. 

$lb("",,,,,"",,,"BOOLEAN","0",2,2,"1",,"bla",$lb(,,"bla","20050502123400"),"",1,"bla",,0)

Is there a way to transform this $lb (without the need of openig the object itself) to a JSON object with the proper table fields as properties?

Many thanks

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.

Hello Intersystems-Community,

I build an API and there I use $order to get the Data from my Globals.
When I first time use that API it's get an error (504 Gateway-Timout > 60 Sec.).

After 2 reloads it works with a loading time of 2 Sec.! Sounds for me like the $order is cached and it works faster. Is it true $order will be cached?

When it works, I only get the error at the next day. So it's very hard to reproduce that error. Is it possible to delete the cache for $order?

Example:

Still working on my first External REST API call, and I am struggling to find the exact answer I am looking for... I get a JSON response from my API call but I am not quite sure how to dynamically get the JSON response into the Ens.Response Object with its lists of Arrays that I have defined.

set tSC = ..Adapter.SendFormDataArray(.tHTTPResposne,"POST",tHTTPRequest,,,tURL)

Hey Intersystems Community,

I have a Problem with the Session Handling in .csp.

I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.

After that the Web Service response is in JSON.

I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html.
Everything Works Fine with the session Handling via Cookie.

FHIR Bulk Data and ndjson

Hi all,

I am testing asynchronous Bulk Data retrieve with a large EHR vendor. When I retrieve the bulk data, they are returning ndjson (CONTENT-TYPE of "application/fhir+ndjson; charset=utf-8"). If I attempt to process that content using JSON functions - I get

ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

For example, the following generates the error

s objArray={}.%FromJSON(quickStreamOut)

The error makes sense in that ndjson is not a valid json format (I assume at least).

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

Dear Colleagues and Friends,

is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.

I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:

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.

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).

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.

Hi There,

I'm fairly new to ObjectScript/Ensemble and I'm sure I may be fundamentally misunderstanding how the %JSONImport/%JSONExport and XDATA mapping work and I was hoping you good folks could help me out. I'm essentially trying to create an object that I can use to translate from one JSON schema to another.

First my class:

2015.2.2 .json format

Is it possible to produce a .json format using Ensemble 2015.2.2? Not sure what the trigger will be as of yet, but we have our local Department of Health trying to develop a reporting piece using .json.

Not sure how this will work with our Ensemble instance not being in the DMZ to send outside our network, but I thought I would ask anyway to see if it is possible.

Thanks

Hi there,

I'm passing a JSON object to the server as such:

{"key":"value","key":"value","key":"value"}

From the client:

- Build object

object=JSON.stringify(object)

-pass to server side method as %String

On the server:

s object={}.FromJSON(object)

Instead of getting something like

object=<OBJECT REFERENCE>[2@%Library.DynamicObject]

I get

object="991@%Library.DynamicObject"

I can't access that object using %Get as if says invalid OREF.
