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 always struggled with Iterating through a JSON response to pull out certain fields into a Data Class Structure to use to populate fields in a DTL. So I defined the whole structure for the following JSON, with the base structure extending Ens.Response, %XML.Adaptor, and %JSON.Adaptor.
In my previous HttpRequests, I have used Content-Type = application/json but I have a vendor that is requesting we send application/x-www-form-urlencoded. How would I go about formatting the Payload as x-www-form-urlencoded?
Defining my first REST API within InterSystems using iris-rest-Api-template as a basis and I am seeing if someone could provide me some guidance to see if I can make it work.
There is a Master Table within IRIS that I am populating from Epic but want to share it with our Enterprise Application Development Team (Web). As a test I was able to use _SYSTEM from postman to execute the following.
Some languages have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.
The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?
I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.
I am trying to help another group within our organization access a SQL Table that I have created to populate Epic Department Data within our environment and came across the ability to use SQL Seach REST Interface using iKnow.
However, I am having issues trying to get it to work via POSTMAN before I hand off the solution...
the POST URL... https://<servername>/api/iKnow/latest/TESTCLIN/table/osuwmc_Epic_Clarity.DepartmentMaster/search
where osuwmc_Epic_Clarity.DepartmentMaster is the table
I am currently conducting a comparative evaluation of FHIR clients as part of my bachelor thesis in health informatics. One of my evaluation criteria is the response time to support inquiries.
Therefore, I would like to kindly ask the following question as part of my analysis: How can I read and write custom FHIR extensions using your client library?
If available, could you point me to any documentation or examples?
I’m working on an InterSystems IRIS production that needs to call an external API using OAuth client credentials (client_id and client_secret). For security reasons, I must pass these credentials via environment variables in my Docker container.
I have built a REST operation to submit a JSON Request Body, and in the JSON Response Object, I need to pull out certain values like pureID, portalURL, and under the identifiers array the ClassifiedID that has a term."en_US" = "Scopus Author ID"
Is there a programmatic method or specific property to differentiate system-defined (/csp/altelier , /api/mgmnt and so on) or user-defined web applications in IRIS?
I have a rest API Class used for getting data from Cache 2018 version. I have single route '/callfuntions' I send the following parameters to the API :- className, methodName, params I use $CLASSMETHODto execute and send the result back to the client.
If I make more that 10 to 12 requests in quick succession, then it stops sending data.
I am trying to replicate a REST call that I am able to make via a Postman call within a EnsLib.REST.GenericOperation.
It's been a while since I have messed around with trying to make external REST calls. When I execute my REST call, tSC is coming back with an error and I am trying to pinpoint why. I tried turning on ISCLOG = 5 but when calling the REST Operation from the Testing tool it is not logging anything to the ISC log.
While developing web apps the security practice I consider safe and convenient is to create a special Role (e.g. equal application name) which contains security resources which application will need (SQL tables, priviledges, database access, etc) and assign it to the Web Application. So the user gets this role once it loggs in to the application (via password, no password or delegated).
Convenient, right?
So, the question is, when I deploy the app as an IPM module what should I put as a database access?
I deployed an IRIS REST application using Installer class. I think I created the namespace FEEDER database with %DB_Default resource and I used the same resource in Web Application roles. I allowed Unauthenticated Authentication method. I used ^%ISCLOG and reviewed ^ISCLOG. I do not understand why I get 403 Forbidden response.
We are calling a REST web-service from Ensemble using EnsLib.HTTP.OutboundAdapter and redefining the adapter class to set custom headers as described by @Eduard Lebedyuk here: How to set Content-Type
I have set up an EnsLib.REST.GenericService with an EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process.
I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.
As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do :
Hello, I have a problem with a call and I would need some help.
When I call an API with the SendFormDataArray method of the EnsLib.HTTP.OutboundAdapter adapter, I pass it a %Net.HttpRequest object and I receive the following error:
I have correctly entered the url in my business operation and I pass it in the last parameter of the SendFormDataArray method. Do you have any idea, please?
I have a primary dispatch class that implements %CSP.REST.AccessCheck() for some high level access checks before the route table forwards the request to the implementation classes which also implement %CSP.REST.AccessCheck() for some lower level access checks. The idea is that we know where we are in the implementation class and what the user is trying to do, so it makes more sense to check some lower level items there rather than trying to parse out the request at the dispatch class.
I'm modifying a REST interface for a client but it seems impossible to me to modify HTTP Response Status and including custom HTTP Headers either.
My dispatch class (extending %CSP.REST) is contacted through a POST request and the latter is processed in a custom class (extending %CSP.REST as well) accessed as shown in the example below:
I have an API set up in IRIS which is secured using an IRIS authentication service, so there is a bearer token being passed down in the request header.
I sent a http post message with a large message body (approx. 200 kB) to a standard EnsLib.REST.GenericService using a standard EnsLib.HTTP.InboundAdapter.
When inspecting the message in the message viewer I expected to see a HTTPMessage XML in the Contents preview, but I found a GenericMessage with no HTTPHeaders section. After a while, I found out that the display in the message's Visual Trace differs from what is shown, when going to the View Full Contents view in the Contents tab of the message viewer.
