Hi Guys, 

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

 

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

Hi There ,

Hi!

We are using Rest Service with inheritance of  %CSP.Rest, and we are having the following problem: when we receive 100 request from single IP adress - this creates 100 CSP sessions and takes 100 user licence for each request for few seconds. What can we do do about this? We've  set this parameter:

Parameter UseSession As Integer = 1;

Thank you in advance!

Hi All,

I am trying to get JSON data from a REST api.  I am using my web browser to get the data by hitting the URL.

The data is receiving properly, but the JSON contains a few HTML tags.

These tags are not not receiving in the browser while hitting the url. Is there any way to overcome this issue ?

Thanks,

Hello Cache Developers:  I was curious if anyone has ever created a TWAIN interface to their Cache Application?   I am new to TWAIN and hence the reason for this question.  From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application.   I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table.    Any input, sample code, or suggestions is apprec

Is there any good documentation/tutorials on creating gateways in both directions between FHIR and Hl7v2 (for Health Connect)?

the scenarios I'm most interested in

1. Client application sends a FHIR demographic query to Health Connect - and the interface has to convert this to Hl7v2 QBP^Q11 message to the PAS.

2. Health connect sends a PDF document (from a file or HL7v2 interface) to an EPR over FHIR.

Thanks

Stephen

3) EWD(Enterprise web development)

Thanks in advance.

Hello,

I want to convert a json, which passed on in the a REST call, into a request message. 

I use method %ConvertJSONToObject of the %ZEN.Auxiliary.altJSONProvider class.

Set sc = ##class(%ZEN.Auxiliary.altJSONProvider).%ConvertJSONToObject(%request.Content, "TestRequest", .request)

Is there an alternative for this? I want to avoid to use the %ZEN library.

Best Regards

Roger de Coninck

Hi.. I have an issue where we are using OAuth2.0 with the ZAUTHENTICATE routine.  Once our token is validated we are using a users lan id (passed on the ID token) to find a software defined username in a Cache Global.

That is all working fine in ZAUTHENTICATE.. I am setting the software defined username in the Properties("Comment") array and wanting to reference it in the Rest Service Dispatch class.

I'm sending data via ajax to my REST service, and while retrieving any information sent in the url parameter is easy when they're defined in the route, I can't get anything if I store information in the data parameter. For example:

$.ajax({
               url: "ServerURL",
               data: { "some": "json" } //How do I get this information?

...

I've looked at many common solutions such as here:

Suppose I have a web application named "/my/api", with a dispatch class configured (a subclass of %CSP.REST), and I want to be able to respond to:

GET /my/api/something/:id

by loading an object with the specified ID and returning it as JSON

GET /my/api/another-thing/data.js
