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 am using MDX2JSON do display data, it uses CSP REST to retrieve data and uses Password Authentication. I enabled LDAP authentication for this applicaiton, but it does not work.
Let's imagine if you would like to write some real web application, for instance, some simple clone of medium.com. Such sort of application can be written using any different language on the backend side, or with any framework on the frontend side. So many ways to do the same application, and you can look at this project. Which offers a bunch of frontends and backends realizations for exactly the same application. And you can easily mix them, any chosen frontend should work with any backend.
Let me introduce the same application realization for InterSystems IRIS on a backend side.
I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.
If you could point me to any information, that'd be great.
In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.
In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.
Earlier this year, the AppS.REST package was released. AppS.REST is a framework for easily exposing existing persistent classes in IRIS as REST resources. AppS.REST-enabled classes support CRUD operations with little effort from the developer, bridging the gap between persistent data in IRIS and data consumers, such as an Angular front end application.
But IRIS classes are much more than just a definition for loading and saving individual records! This article aims to highlight a few ways to leverage the power of IRIS in your REST applications. Using the Phone.Contact sample app, we'll look at out-of-the-box query support, use of class queries and finally ObjectScript methods.
I have a vendor that is sending an HL7 message. But when I asked for more detail about their mapping tables, they told me they typically don't supply that but supply an API for customers to call so they don't have to define tables and it is more dynamic.
So with that being said I am creating my first REST operation. I understand the gist of how a REST operation works in working with other types out Non HL7 Operations (SOAP, SQL) before. You send a request and get a response back, that part I understand.
We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager.
Our aim is to implement a Microservices Architechture where Services are small in size, bounded by contexts, autonomously developed, and independently deployable.
We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.
I am trying to figure out if we can extend a business process in IRIS. My Use Case is that I am developing RESTful Interfaces and my each REST Interface needs to go through certain processes before getting to the actual action.
e.g. I have 2 REST Interfaces, GetPatient and GetEncounter. Both of these need to invoke "GetToken" Business Operation to go to the Authentication server to get an authentication token before they go ahead and hit the Business Operation to Get the data i.e. Patient or Encounter.
InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.
Hi All, I am implementing REST API's in IRIS using the below link as a guide. I chose this approach so i could have a single entry point for requests regardless of namespace
a sample form the HIHLib.REST.Server class i am using is below. my question is does IRIS and CSP cache responses for requests to the CSP.REST class? and if so what parameters or properties do i need to enable?
I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />
My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.
Bulid REST API application built with ObjectScript in InterSystems IRIS. It also has OPEN API spec, can be developed with Docker and VSCode, can be deployed as ZPM module. can be used as Overbooking System data REST api.
In the previous article, we discussed the development of business processes, which are part of the components required for system integration and serve as a production coordinator.
Enjoy watching the presentation of the IRIS-REST-API-DATABASEMANAGER app that allows you to create persistent Tables and Data in InterSystems Cache Database:
In this article, I would like to talk about the spec-first approach to REST API development.
While traditional code-first REST API development goes like this:
Writing code
REST-enabling it
Documenting it (as a REST API)
Spec-first follows the same steps but reverse. We start with a spec, also doubling as documentation, generate a boilerplate REST app from that and finally write some business logic.
This is advantageous because:
You always have relevant and useful documentation for external or frontend developers who want to use your REST API
Specification created in OAS (Swagger) can be imported into a variety of tools allowing editing, client generation, API Management, Unit Testing and automation or simplification of many other tasks
Improved API architecture. In code-first approach, API is developed method by method so a developer can easily lose track of the overall API architecture, however with the spec-first developer is forced to interact with an API from the position if API consumer which usually helps with designing cleaner API architecture
Faster development - as all boilerplate code is automatically generated you won't have to write it, all that's left is developing business logic.
Faster feedback loops - consumers can get a view of the API immediately and they can easier offer suggestions simply by modifying the spec
InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.
In this article, we would use InterSystems API Management to Load Balance an API.
In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.
There are many different reasons why we might want to do that, such as:
Load balancing to spread the workload across servers
Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
Canary deployment: we might publish the new version only on one server and move 1% of clients there
Hi Community!
Today I'd like to share with you a link to some exercises from a workshop about developing REST APIs and how to manage them using InterSystems API Manager.
In the first installment of this article series, we discussed how to read a “big” chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a class. Now let’s look at how to save such data and metadata in JSON format.
