#REST API

I am trying to use postman to start the restapi classes from a json openapi2.0.0 file.

POST: https://myserver.com/api/mgmnt/v2/requestAPI. The body contains the openapi2.0.0. The application api/mgmnt has in security settings: password. JWT is not selected. I set postman authentication to basis authentication and gave username and password. I also set in headers IRISUsername and IRISPassword. I have 401 Unauthorized.

Is the only way to go through is to build an oauth token? or do I miss something?

Thank you very much.

Hi all,

For a requirement of the customer, we have a BS Rest api with a lot of methods, we need to get the IP of the caller, the method and what is the time that the API has taken to process.

I've found the event onPreDispatch where I can take the IP, ClassMethod, etc.. I'm using a global variable to save this information.

ClassMethod OnPreDispatch(pUrl As%String, pMethod As%String, ByRef pContinue As%Boolean) As%Status
{
	set^CallApi($CLASSNAME(),$JOB,"url") = pUrl
	set^CallApi($CLASSNAME(),$JOB,"method") = pMethod
	set^CallApi($CLASSNAME(),$JOB,"Start") = $HOROLOGset^CallApi($C

Dear,

I'm trying to configure a new interface that reads HL7, transform them into FHIR messages and then send POST or PUT or DELETE depending on HL7 doc type.

1-I added an HL7 TCP service that reads ADTs messages

2a-Send ADTs to a process to transform them into SDA  (using the following command:  do ##class(HS.Gateway.HL7.HL7ToSDA3).GetSDA(request,.con))

2b-Extract the patient MRN and add it to the AdditionalInfo property  (using the following request message class: HS.Message.XMLMessage)

3-Send the SDA message to the built in process: HS.FHIR.DTL.Util.HC.SDA3.FHIR.Process.

4-Send FHIR request to

Hello,
First of all thanks for your time and help with this question.

We wonder how could we convert a String which represents an XML, to a class which extends from Ens.Response

Our context is a REST Operation, where we currently split the String with $PIECE and set each propertie as follows:

set codigo = $PIECE($PIECE(httpResponse,"<error><codigo>",2),"</codigo><descripcion>",1)
        set descripcion = $PIECE($PIECE(httpResponse,"<descripcion>",2),"</descripcion>",1)
        set codigoSERAM = $PIECE($PIECE(httpResponse,"</error><codigo>",2),"</codigo></resultado>",1)

Hello everyone!
So, I am supposed to receive a REST-request into my production, and I need to send it, exactly as I received it, to another server.
I am struggling to find any good info on this, and have a hard time coming up with a good approach.
What would be the easiest way to do this?
- I have so far thought about possibly doing it with an EnsLib.REST.GenericService and then sending it with an EnsLib.REST.GenericOperation.
- I have also thought about manually creating a rest-service and somehow using %request and sending it directly if that would be possible.

I would be very thankful if I could

Hi all,

As you know, it is very complicated to debug a Business Service Rest API because the object is created when the applications receive a request, so we cannot have the JobId that we can use to debug.

https://docs.intersystems.com/iris20211/csp/docbook/DocBook.UI.Page.cls…

So, I'm trying to get the JobId when the class is being created, write a trace in OnInit() method and write the JobId in a log info

Method OnInit() As%Status
{
	$$$LOGINFO("JobId: "_$JOB)
	hang20breakQuit..OnInit()
}

Unfortunately, it seems to ignore this method because it doesn't show any traces

Hello,

I have a problem with a FHIR Interop scenario that the HTTP Header Value content-type between IRIS and client changes in case of an error (HTTP 422). If I set the status in the response to 200 OK as the last step in the service class, the return transmission works.

Within my operation class, the error code is taken from the source system and entered in the HS.FHIRServer.Interop.Response message. 

Within the CSP gateway I am also shown that the content type is 422 application/fhir+xml and is returned.

When I look at the packet in Wireshark, it is already text/html. 
A URL rewrite is not

Hello Everyone,

The Certification Team of InterSystems Learning Services is developing an InterSystems IRIS Developer Professional certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.

Note: This exam will replace the current InterSystems IRIS Core Solutions Developer Specialist exam when it is released.

How do I provide my input?

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.

    set vProfile = %request.Get("testprofile")
    set vFilen 

Hello everyone!
I am receiving a HTTP multipart/form-data request into my rest service.
How can I read the values for each Key in the form?
The key "Profile" is sent to my service as a String data type.
The code I have below does not seem to work, where I try to read the Key profile in the form.

I appreciate all the help I can get! :)

I am using Intersystems Iris Community Edition. I have created a Rest Api to post HL7 message directly through postman. It is working fine, But I want to create the business service to read the HL7 message from Rest- Api. I tried to create this, but I am not understanding how to do that. Can anybody help me?

So far, we have covered how to use ObjectScript to manage users, roles, resources, and applications.

I've created a Rest Service as described here 

Configured the webapplication as described in the previous link, and now have a URL which I call in PostMan

http://VIR-HC-DEV-01.gmmh.nhs.uk:52773/api/mgmnt/v2/parisconnect/PCRest

Which returns the JSON spec as I would expect:

{
    "swagger": "2.0",
    "info": {
        "version": "1.0.0",
        "title": "Swagger Petstore",
        "description": "A sample API to demonstrate features in the swagger-2.0 specification",
        "termsOfService": "http://swagger.io/terms/",
        "contact": {
            "name": "Swagger API Team"

Update - I answered my own question, so I'll just leave this here in case it can help someone.

Hello Guys,

Our cache application uses REST web services and handles single API request perfectly with response (response status and related data). But sometimes user sends multiple requests to the same API simultaneously ( ie, without waiting for the first to respond ), where one request will succeed (not necessarily the first) and the others will fail. 
So, I need to handle the requests one by one after completing and sending the response for first request in the queue then process the next request and so on.

Is there any appropriate way of handling this problem? 

I found that, cache supports mu

Hello Community,

Is there any way to avoid generating the built in validation inside the classmethod from the .disp class definition. I've added the resource with path parameter as integer in swagger 2.0 open API.  The class method(in my case getRandom is the class method) inside .disp handles the integer validation by default. Is there a way to avoid/remove by default.

Hello everyone!
I have to build a REST service that receives a POST HTTP-request, collect a file from that request in the Form data and then send it in another HTTP Post request through Form Data. However I can't really seem to send the file, and I do not know where it has gone wrong. All I am getting told is that no file is being received from my HTTP Post request. I am reaching the REST Service I am supposed to send the request to, but nothing is being sent.
I would be really thankful if someone could give some insight why nothing is being sent in my request. Thanks beforehand! :)

Welcome everybody!

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.

Generally the simplest way I have found to perform this task is to transform the file from the frontend to the Base64 format and make a POST call to our server attaching the Base64 obtained to a JSON message in which I indicate in a parameter the name of the file and in another the encoded data. Something similar to this:

{
    "file

I getting the response back to my method fine,

but it is not returning to my BPL.

What am I missing to get the response back to the BPL?

// Execute REST Call
set tHttpResponse=##class(%Net.HttpResponse).%New()
set tSC = ..Adapter.SendFormDataArray(.tHttpResponse,"POST",tHttpRequest,"","",tURL)
set tStatusCode = tHttpResponse.StatusCode
$$$TRACE("Status Code: ["_tStatusCode_"]")
do ..logJSON(tHttpResponse.Data.Read(),"Post Relation Response")

// On HTTP 200 - OK
if tStatusCode = 200 {
     do tHttpResponse.Data.Rewind()
     do pResponse.%JSONImport(tHttpResponse.Data.Read())
     quit $$$OK

Hello all,

I have downloaded the latest community edition of IRIS and have stood up a vista system with File Manager, Taskman, the RPC Broker  etc up and running just fine on the latest FOIA release.

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

That’s what the InterSystems documentation on its reference website tells us, but what do you actually have to do to deploy a production ?

Productions can be composed to connect external systems to the IRIS Data Platform.

Hello,

First of all thanks for your time, thoughts, teaching and help:

We wonder how could we get the metrics from http://[Ip]:[Port]/api/monitor/metrics and use them in Kibana to chart statistics.

We would like to ask you how do you use the api monitor metrics, and as a second question, how would you suggest to utilize them in a third party software as Kibana to chart them.
 

We have thought to do the following:

1. Retrieve Metrics from Intersystems HealthShare API: Use a tool or script to make requests to the Intersystems HealthShare REST API and obtain the list of metrics.

After some trials, I am comfortably on my way developing spec first REST APIs using /api/mgmt/, OpenAPI 2.0, testing with Postman.

My question is related to scaling up.

Assume these things:

- Our software is CSP web app and it's web application is '/csp/application'

- I created a new REST enabled web app called '/csp/application/v1' and for my first API I created a spec that defines an endpoint /getTeapots so the endpoint is localhost/csp/application/v1/getTeapots

- Using the /api/mgmt/ endpoint, I loaded the spec into API.TeapotLibrary

- The dispatch class in '/csp/application/v1' thus is

Hello,

First of all thanks for your time reading this post, and thanks for your help with your answers, thanks.

We have the following doubt: We need to create a REST Service in HealthShare, to process incoming calls with the following URL's format:

https://host:port/api/studies?patientId=11473564
 

To accomplish this task, we have previously read:

https://community.intersystems.com/post/advanced-url-mapping-rest

https://community.intersystems.com/post/how-do-i-process-querystring-pa…

https://community.intersystems.com/post/how-get-param-passed-get-rest-q…

And

I was attempting to find a solution to grant clients anonymous access to certain API endpoints while securing others within my REST API. However, when defining a Web Application, you can only secure the entire application and not specific parts of it.

I scoured the community for answers but didn't find any exact solutions, except one recommendation to create two separate web applications, one secured and the other unsecured.

I am making a POST request to an API. In the case of an error, I don't know what parameters the response JSON will contain (they will change depending on the error). I am converting the response stream to an object but then I need a way to loop through all the properties and access their values. The following code is making the POST request, reading the response, and trying to add all the error messages to an array. But I can't iterate over the properties of the tProxy.errors object because it is a %ZEN.proxyObject. Is there a better way to do this?

Set tSC=..Adapter.Post(.tHttpResponse, ,
