#REST API

17

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.

This earlier article already announced the new iKnow REST APIs that are included in the 2017.1 release, but since then we've added extensive documentation for those APIs through the OpenAPI Specification (aka Swagger), which you'll find in the current 2017.1 release candidate. Without wanting to repeat much detail on how the APIs are organised, this article will show you how you can consult that elaborate documentation easily with Swagger-UI, an open source utility that reads OpenAPI specs and uses it to generate a very helpful GUI on top of your API.

As many of you, our partners, are more widely using modern UI frameworks to create client front-end, you may have encountered a question, "So how do I secure my data when I just finished developing all new fancy browser based client experience?"

The answer is easy. Use a standard, proven OAuth2 and OpenID!

"OK, but how can I do it? I have never done it before."

No problem, just have a look here, if your client is Angular (not AngularJS) based, there is a demo project available for you to review and get inspired!

A framework yes, but a suitable framework

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

login failure

I am still working on iris-for-money app: https://github.com/oliverwilms/iris-for-money

Account.csp posts a rest call with _SYSTEM username and the password.

xhttp.open("POST", "/restapi/sql/" + query, true,"_SYSTEM","SYS");
xhttp.send();

/restapi web application has Password Authentication Method enabled.

SYS is the correct password for _SYSTEM user.

I do not understand why I see login failure in Audit database.

RESTful Exception Handling

A beginner’s guide to Exception Handling in RESTful web services. The article gives an example how the various error conditions during processing a service request can be handled.

We expect our client – server communication working in a flawless operational condition, running error free software. But we are prepared to handle exceptions. Are we? So far in the examples of the previous sessions were not. We did not care about exceptions. The result? In any error incident it took ages to figure out what the problem is and more importantly how to fix it.

If I add the same patient data with a different unique ID then it inserts as new data using a POST request.
So, In the FHIR server How can I prevent this kind of thing by using POST requests?
Note:- I don't want to use a PUT request for the same. The main thing is I want to get a unique patient record.
Que:- Is there any way to check data duplication on each FHIR resource?

Thanks & Regards,

Forwarding Requests in a REST Service

One useful feature of our REST framework is the ability for a dispatch class to identify request prefixes and forward them to another dispatch class. This approach of modularizing your URL map will improve code readability, enable you to easily maintain separate versions of an interface, and provide a means to protect API calls that only certain users will be allowed to access.

Hi-

Im curious if there is any specific configuration that has to be done on an IIS web server to serve up RESTful web services.

I have a server that has IIS installed, with the CSP gateway. a second server that has Cache installed on it.

I have configured a web application using the Cache System Management Portal for the web services that has a dispatch class pointing to my dispatch class.

I have created an application mapping in my CSP Gateway Management Portal on the web server such that url's with /webservices prefix are routed to my cache server.

I'm working with isc.rest and am going through the tutorial right now. My project directory exists on my IRIS server. When I try to create a module.xml file in the root package, I get a #16006 error. I see that there is a "generate" command for zpm that should create a module.xml for me on my local filesystem. How can I create this module.xml in the same folder that holds my code living on the IRIS server?

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?

Applications that work with bill payments and receipts, as well as the delivery and inventory of items, generally require the use of barcodes or QR Codes. The latter is used in even broader scenarios since the QR Code can store more information than a simple bar code. Thus, it is important to have the ability to generate barcodes and QR Codes or read the data stored in them from an image or a PDF. This article will show you how to do this using Python and some of its free libraries.

404 Not Found

{
"error": {
 "errors": [
  {
   "domain": "global",
   "reason": "notFound",
   "message": "Not Found"
  }
 ],
 "code": 404,
 "message": "Not Found"
 }
}

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?
