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.
I have the following setup: REST broker calls inProc BO via BS. As BO initialization is time-consuming, I want to reuse the same BO during the CSP process lifetime.
I'd like to start playing around with some simple Angular app with IRIS REST Api but I'd like to do so in the best way possible, did you have any best practices and/or VSCode setup to make life easier?
Keep in mind I've never developed an Angular APP before, so also some simple example will be really useful.
Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?
In this article, we will learn how to set up a REST API for the IRIS Security Package. We will be able to create users, roles, add applications, etc... by simple HTTP requests as well as generate a client application in ObjectScript.
I am playing around with trying to make an Epic REST API call from an operation, and from what I understood because the request has to be sent as POST, I need to send the request as JSON. However when I try taking the request and running %ToJSON against it for the payload to be created I am getting an error...
I want to develop a web application in which a user can log in through the user credential of intersystems that is created in Management Portal for a specific role. How can I authenticate the user and get any token or login cookie through which user can call other apis
I want to connect IRIS system as it has all the database tables. on top of that I am creating a REST API in python. How can I connect to IRIS DB. here is my example code for connection
after this connection is created but how can I get tables data. Please let me know more about how we can integrate IRIS database into a python REST API.
One of the most common needs of our clients is the creation of REST services that allow access to the information present in IRIS / HealthConnect. The advantage of these REST services is that it allows the development of custom user interfaces with the most current technologies taking advantage of the reliability and performance of IRIS in the back-end.
I am trying to call to a website that renders a xml structure as a response.if I put the url on the browser an xml rendered page is returned but if i call to this using the below code I get an object reference error which I am finding had to understand is there anyone who could help understand this error or point me in the right direction thanks.
How many times do we find ourselves rebuilding, copy-pasting, adapting, Business Operations that make calls to REST services, and only adapting one or another part of the final code. This is annoying a lot. To resolve this our inconvenience, I present to you Interopway REST, a set of classes (a micro framework) that allows us to just add Business Operation to Production and use it.
Being a programmer nowadays is basically the geek version of being a polyglot. Of course, most of us here, in the InterSystems Community, “speak ObjectScript”. Howeever, I believe this wasn’t the first language for many people. For instance, I had never heard about it prior to getting the appropriate training at Innovatium.
I have a production with a HLv2 HTTP Listener.
For demo purposes, I need to send HL7 messages directly from a browser. Here is an example (React/typescript):
Thank you very much for reading the doubt and above all thank you very much for answering.
Given the following use case:
If we have a Destination Service that through a HTTP GET by REST gives us a certain JSON response, where it should be noted that it is a list of objects where each object in the list does NOT have a key:
I am looking for a sort of REST interoperability adapter that can forward REST calls within HealthConnect. If necessary, we need to adjust the requests or responses.
For Fhir calls, we use the FHIR Interoperability Adapter. This works perfectly; a message comes in as HS.FHIRServer.Interop.Request, and a message HS.FHIRServer.Interop.Response goes out. I can make adjustments as needed to both the request and response. I am looking for the same functionality, but then for non-FHIR REST calls.
In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.
You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.
It is clear how to get the request header value with a specific name:
Class My.RestController Extends %CSP.REST
{
ClassMethod processRequest() As %Status
{
#dim request as %CSP.Request
set request = %request
set h = ##class(%REST.Impl).%GetHeader("...")
...
return $$$OK
}
But I can't figure out how to enumerate ALL the request headers (and also get all values).
However our org requirement is for a caller to provide the API version in the HTTP request header. I am finding the cleanest way to route to the correct class using the header version. My classes are setup as
I am using the %Net.HttpRequest class to download a file from the internet .using the following code. When a file is returned in the DOM I am able to read the file content and save it to the desired location but when my response is a download dialog nothing is returned in the HttpResponse. Am I doing something wrong here is where I have gotten to so far any help appreciated.
This week I was able to demo a proof of concept for our FMS interface on traffic cop architecture to my team. We are working on modernizing an Interoperability production running on mirrored Health Connect instances. We deploy IRIS workloads on Red Hat OpenShift Container Platform using InterSystems Kubernetes Operator (IKO). We can define any number of replicas for the compute stateful set where each compute pod runs our Interoperability production. We introduced Horizontal Pod Autoscaler (HPA) to scale up the number of compute pods based on memory or CPU utilization.
InterSystems IRIS versions 2022.2 and newer feature the ability to authenticate to a REST API using JSON web tokens (JWTs). This feature enhances security by limiting where and how often passwords transfer over the network in addition to setting an expiration time on access.
The goal of this article is to serve as a tutorial on how to implement a mock REST API using InterSystems IRIS and lock access to it behind JWTs.
