#REST API

19

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.

Hello All,

I am compiling a REST Operation to call our hospital Administration system, following tutorials around the REST API's etc. First time we have integrated like this so not much knowledge around our hospital - hoping someone on here can help.

I have been using the JSONStreamToObject Method which is working as i expected, apart from trying to get a specific item in the example JSON Response as follows:

{"test":"abc","name":[{"use":"usual","family":"Matest","given":["Mia"]}]}

I have an interoperability production that functions as a FHIR proxy. I have a need to add an HTTP Header value to the outbound request. I've subclassed HS.FHIRServer.Interop.HTTPOperation, but I cannot find a way to add an HTTP Header to the request. The HTTP class used in HS.FHIRServer.Interop.HTTPOperation is HS.FHIRServer.RestClient.HTTP. That RestClient class does not seem to expose or allow modification of the actual HttpRequest.

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?

Hello everyone!
I am wondering how I can retrieve multipart form-data from a request that is coming into my REST-service.
I am supposed to retrieve a string and a file. The file is being retrieved without issues, but the "testprofile" string is not being retrieved at all.
It just logs a an empty entry.
The request that is sent to my REST-service has the Content-Type: multipart/form-data
Thanks beforehand for the help! :)

Down below is the code I use right now to retrieve the string and file from Form-data Rest HTTP-request to my service.

I am attempting to make a FHIR call against the Epic Repository through Intersystems. I have setup a Service client per Create FHIR REST Client | InterSystems Developer Community | Business

but I have set it up using OAuth and HTTPS.

I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG

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.

Hi All,

I am trying to get JSON data from a REST api. I am using my web browser to get the data by hitting the URL.

The data is receiving properly, but the JSON contains a few HTML tags.

These tags are not not receiving in the browser while hitting the url. Is there any way to overcome this issue ?

Thanks,

I use a swagger file and ##class(%REST.API).CreateApplication to create the rest api.

There is an interesting post: https://community.intersystems.com/post/download-file-rest-api-operation, but it is code, not a swagger configuration. disp.cls returns always a header content : application/json that of course fails as I am not always returning a json

I can not figure out what to put in swagger. Some examples I tried:

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.
