#REST API

Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.

REST and CSP Sessions

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!

Proper Role Permissions for Executing Queries via REST

Good afternoon - I am in the process of writing a AngularJS front-end for some CoS functions that my integration team uses for auditing, analyzing and various other purposes. I have re-tooled the functions to return JSON results that AngularJS can then interpret and display. Many kudos to the AngularJS series on this site for giving me a jump start.

Bearer Token Authorization issue with RESTFul API from Ensemble REST Operation EnsLib.REST.Operation

Hi dev community,

I am currently working on a project to send documents to a RESTful based API that supports bearer
Token Authorization.

When we try to fire a JSON request from our EnsLib.Rest.Operation towards the 3rd party API with a
valid Token we keep receiving Authorization Error codes HTTP 401 back.

If we use the same request and same Token from a test utility such as Postman the request is
successful and we are able to move past the authorization stage.

How to expose Cache data as an OData API?

We have a Cache database in Azure, and want to expose it as an OData source (link).

My first attempt was to use Microsoft's Visual Studio 2017 and Entity Framework to create the data models...but it seems as if EF and Cache don't work together. (I do have those instructions from 2013, but they don't work. (See other post. Best answer seems to be "migrate to IRIS 2019.1.")

Is there any other form of OData support?

FHIR Documentation/tutorials

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

JSON Syntax

Hi,

I'm using InterSystem Cache v2015.2.5 and I'm implementing a REST API and returning JSON.

Following the documentation I see examples like this

Set obj = {"destinations": ["London","Madrid","Tokyo"]}
Write obj.%ToJSON()

However, I have a compilation error

ERROR #1054: Invalid expression : '{"destinations":'

Is there something that needs to be enabled on Studio to allow this syntax?

Thank you,

I am trying to use the automated unittest class for a %CSP.Rest service.

So my Unittest code set's %request and %response from %CSP.Req/resp respectively

I build a tProxy with the fields I need for the post and set it %ToJson... I have tried seting %request.Content = tProxy (and not)

I call the method for the post url directly...

When that method calls %fromJson to set an object with the info. I passed...

 ],
 "code": 404,

I want to do something like the above sample from a Google Storage JSON API. I have a call to Write obj.%ToJSON() followed by return ..ReportHttpStatusCode(..#HTTP404NOTFOUND) however the HTTP Status code is always 200. If I remove the Write obj.%ToJSON() statement it returns a 404 status with no body. How do I return both?

REST POST 405 error

I'm testing out the new %CSP.REST way of creating an api and having a problem with a POST getting a 405 error.

I get data returned when I do a GET, so I don't think it's a configuration issue or a class issue.

I have no problem with %CSP.Page when creating a REST type method. So what am I missing?

Can someone give me some advice?

Thank you.
