Hello everyone,

I would like to know if it is possible to connect to a REST API through production, without having to write a class that extends %CSP.REST. Is there a GUI based way where I can configure my GetRest and then use EnsLib.REST.GenericService and EnsLib.REST.GenericOperation to configure my production and perform transformations? 

While reviewing our documentation for our ^pButtons (in IRIS renamed as ^SystemPerformance) performance monitoring utility, a customer told me: "I understand all of this, but I wish it could be simpler… easier to define profiles, manage them etc.".

After this session I thought it would be a nice exercise to try and provide some easier human interface for this.

The first step in this was to wrap a class-based API to the existing pButtons routine.

I was also able to add some more "features" like showing what profiles are currently running, their time remaining to run, previously running processes and more.

The next step was to add on top of this API, a REST API class.

With this artifact (a pButtons REST API) in hand, one can go ahead and build a modern UI on top of that.

For example -

Hi guys,

has anyone done a simple angular searchbar with a REST API on Caché in the back?

I've done this Let's write an Angular 1.x app with a Caché REST backend here in the community and it

works fine for me.

The REST in Caché is already developed but im hanging at the searchbar in Angular, don't know how to solve this.

Has somebody an example to help me out?

Any help would be appreciated.

Hi Community,

This post is a introduction of my open exchange iris-fhir-client application.

 iris-fhir-client can connect to any open FHIR Server by using embedded python with the help of fhirpy Library.
Get Resource information by terminal and by using CSP web application.

Hey Community,

Exciting results from a massive workload to test InterSystems API. We'll describe how we're trying to push the boundaries of the current technology in the public cloud:

Hello All,

I am just wondering if there is any inbuilt function or utility available in IRIS to clean up "null" elements from JSON e.g. I want to remove "null" elements from payload below before I do any processing with it.

What it the best method to call an object without ID but having RowID

SET task.Title = ##class(RESTAPI.TITLE).%OpenId(obj.Title)

I have tried using %OpenId() but it returns null

Any help would be grateful thank you.

Given I have a property 

Class All.AllBooks Extends %Library.Persistent
{

Property ID As %Integer;

Property Title As User.Book;

}

In the class method

ClassMethod GetABookById(id As %Integer) As %Status
{

SET MyBooks = ##class(All.Allbooks).%OpenId(id)

SET obj = {

     "ID" : (MyBooks.%Id())

     "Title" : (MyBooks.Title)

}

WRITE obj.%ToJSON()

Quit 1
}

How do Access the foreign key in JSON() data

Recently I needed to generate a Swagger spec from persistent and serial classes, so I'm publishing my code (it's not complete - you still need to hash out the application specifics, but it's a start). It's available here.

Let's say you have these classes:

Class REST.Test.Person Extends %Persistent
{

/// Person's name.
Property Name As %String [ Required ];

/// Person's Social Security number. This is validated using pattern match.
Property SSN As %String [ Required ];

/// Person's Date of Birth.
Property DOB As %Date;

/// Person's home address. This uses an embedded object.
Property Home As Address;

/// Person's office address. This uses an embedded object.
Property Office As Address;

/// Person's spouse. This is a reference to another persistent object.
Property Spouse As Person;

/// A collection of strings representing the person's favorite colors.
Property FavoriteColors As list Of %String;

/// A collection of strings representing the person's favorite colors.
Property FavoriteNumbers As array Of %Integer;

/// Person's age.<br>
/// This is a calculated field whose value is derived from <property>DOB</property>.
Property Age As %Integer;

}

Class REST.Test.Address Extends %SerialObject
{

/// The street address.
Property Street As %String(MAXLEN = 80);

/// The city name.
Property City As %String(MAXLEN = 80);

/// The 2-letter state abbreviation.
Property State As %String(MAXLEN = 2);

/// The 5-digit U.S. Zone Improvement Plan (ZIP) code.
Property Zip As %String(MAXLEN = 5);
}

The GA release is now published for the 1.5 version of the InterSystems API Manager (IAM).

Hi Team,

I got a 404 status code(fhirResponse.Status) in the below code while inserting patient resources. Other resources data are successfully inserted.

Class HS.FHIRServer.Interop.Operation Extends (Ens.BusinessOperation, HS.HC.Util.Trace.Helper)
{ Parameter SETTINGS As %String; XData MessageMap
{
<MapItems>
<MapItem MessageType="HS.FHIRServer.Interop.Request">
<Method>DispatchRequest</Method>
</MapItem>
</MapItems>
} Method DispatchRequest(pInteropRequest As HS.FHIRServer.Interop.Request, Output pInteropResponse As HS.FHIRServer.Interop.

If I add the same patient data with a different unique ID then it inserts as new data using a POST request.
So, In the FHIR server How can I prevent this kind of thing by using POST requests?
Note:- I don't want to use a PUT request for the same. The main thing is I want to get a unique patient record.
Que:- Is there any way to check data duplication on each FHIR resource?

Thanks & Regards,

Harshdeep Acharya

I have the " FHIR Production" which converts HL to FHIR, CDA to FHIR and accepts FHIR rest API to insert data into the FHIR repository.

When data is added by the above production, The Repository Stores that data as new data.

Is there any way to check resource duplication before inserting them into the repository?

Thanks,

Vivek Nayak

Hi,

Working on integrating with O365 Sharepoint REST API. I would want to know if anyone can share their experience with integration with Sharepoint REST API and how they implemented security?

Thanks
Kiran Kumar

User calls my REST service. I need:

• Redirect him to a POST url
• Provide request body

Is it possible? How?

Creating REST API using InterSystems ObjectScript is very easy, but some recipes can help you into this process:

1) To create your REST API extends %CSP.REST and Go to System Administration > Security > Applications > Web Applications > Click the button Create New Web Application and set the Name, REST Dispatch Class with your package and classname and choose the Allowed Authetication Methods. See this example:

Edit Web Application

2) Configure your REST API using ZPM configuration. To do this follow this sample (watch the tag <CSPApplication>):

Spring Boot is the most used Java framework to create REST API and microservices. It can be used to deploy web or executable web or desktop self-contained apps, where the application and another dependencies are packaged toghether. Springboot allows you do to a lot of functions, see:

Note: to learn about SpringBoot see official site - https://spring.

If your REST API need return a file to the client download, this is the source code that you could write (P.S.: extracted from the question https://community.intersystems.com/post/download-file-rest and its responses):

If you need create a upload REST API with IRIS is very simple. Do these procedures:

From Postman client you send a file

P.S.: It is a multipart form with a file type using "file" in the name. The request type is form/multipart. See the http request:

POST /image-analyzer/postFile HTTP/1.1
Host: localhost:52773
Content-Length: 213
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="/C:/Users/yurim/OneDrive/Imagens/salesschema.png"
Content-Type: image/png

(data)
----WebKitFormBoundary7MA4YWxkTrZu0gW

I'm trying to send an HTTP POST request with form-data from an Angular app to a Cache backend, but my request fails with a 406 Not Acceptable error.

httpRequestHeaders = new HttpHeaders({
  Authorization: 'Bearer ' + sessionStorage.getItem('access_token'),
  Accept: ''
}); 

uploadFile(file: File) {
  const formData: FormData = new FormData();
  formData.append("file", file);
  const req = new HttpRequest("POST", this.postURL, formData, {
    reportProgress: true,
    responseType: "json",
    headers: this.httpRequestHeaders,
  });
  return this.http.request(req);
}

Hello everyone,

I want to see all properties from a %Net.HttpRequest, I tried to use:

zw objHttpRequest

It's show all the properties, but I want something more easy to analyse like a curl command, is it possible?

Thanks.

Our previous lesson ended with us serving a Message value obtained from a Caché REST service to the client, using Angular as a runtime.  While there is a lot of moving parts involved in this process, the page is not especially exciting at the moment.  Before we can start adding new features, we should take a step back and review our tools.

This tutorial is using the JSON functionality built into 2016.2+ versions of Caché.  This functionality is partially available in 2016.

The XData (https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GOBJ_XDATA) is a powerful feature to set documentation and metadata information for classes and methods. The %CSP.REST class uses XDATA to mapping REST calls (), so in this article you will see how to use XData into your apps as code, not only as documentation.

When you write XData comments/definitions, the IRIS store it into %Dictionary.ClassDefinition (for classes) %Dictionary.MethodDefinition (for methods).

For those that, at some point, need to test what means that of ECP for horizontal escalability (computing power and/or users and processes concurrency), but they're lazy o have no much time to build the environment, configure the server nodes, etc..., I've just published in Open Exchange the app/sample OPNEx-ECP Deployment .

What about having your IRIS REST APIs scanned every push you did and being reported on possible vulnerabilities? This is what I am going to show you in this article.

Recently, we had the Security Contest with amazing applications and examples showing how to improve security on your IRIS solutions. One of such examples was the , made by me and my colleague Henrique Dias. Our application shows how to use the OWASP ZAP API scanner to perform security tests on your REST APIs OpenAPI definitions generated by IRIS.
