#REST API

23

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.

How to send a file via JSON

I have a text file that I pick up in a Business Service and need to send it to our vendor via JSON. I assumed (probably wrongly) that I could just create a RESTful Business Operation, plug in the server IP and URL as well as complete some of the other fields on the BO to send the file. When I do this, I get the following error:

Hi all

Does anyone have an easy way of reading the cdata in the xml response returned buy a Webservice?

At the moment I have a XML class and then I use read.Correlate() to read through that XML bit.

However, depending on the message I have different things in the CData and I don't want to create a class for each one of these.

The API returns the cddata as KeyValueOfstringstring.

FIrst of all thank you for your time in reading this question and writing a response,

We would need some help,

-> Our objective is to control which method is being used in the service: GET POST PUT

We have tried to understand the example REST Service: Demo.REST.DirectoryService

After that we have tried to create our own custom rest service,

please take a few minutes to examine the following code:

Hi everyone - In IRIS we would like to arrange the access of two users in such a way that each has access to exactly one (his) database only. Which resource does this (%DB_%DEFAULT allows each of the two users access to both databases). If you create new resources (%DB_Database1 and %DB_Database2) and then add them to individual roles (each for the user to), the access for the users, for example, via a REST client does not give the desired separation (instead once Ok, other database 401 Unauthorized both OK).

Hi,

I am working with this Ensemble Business Operation, which extends the EnsLib.Rest.Operation.

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...

I built the OpenWeatherMap Rest Operation described in the article above.

I would like to access the weather.id weather.main, and weather.description. However, these objects are in a JSON Array.

How do you access these three objects in Objectscript.

I am working on an angular applications and build a web application (Rest API) on IRIS for health, the web application uses a password authentication and setup with the default csp session time out (15 minutes). If the user make an REST API call from the angular application after the session expired, it displays a login prompt...is that anyway that we can disable the login prompt and just simply return http status 401? When the angular application received the status 401, it can redirect to angular error page.

Thanks,

Hoi

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.

I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL. Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.

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.

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?

Hi Guys,

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

Hi,

I've added a REST service which worked fine on our test system but failed on the production environment because UnknownUser does not have %All set and I really don't want it set on production (in fact I've also switched it off on test).

Is there a way to allow a single REST service to have unauthorised access?

I was thinking adding a resource/role to UnknownUser specifically for that service but I've never touched on Users/Roles/Resources so I'm struggling to work out what needs adding where.

Thanks

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

https://community.intersystems.com/post/restful-exception-handling

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 send a POST request to my REST API and I'm getting this error and most likely due the lack of experience, I have no idea how to fix this issue:

"id": "JSONImportError",

"params": [

"AlertText",
