#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.

REST API Request Logging

I am working on my first REST operation to send a API Request to an internal server within our Network. I have finally got past the point of being able to connect using a SSL/TLS Configuration, but I am getting a ERROR <Ens>ErrHTTPStatus: Received non-OK status 403 from remote HTTP server: 'HTTP/1.1 403 Forbidden'.

Still working on my first External REST API call, and I am struggling to find the exact answer I am looking for... I get a JSON response from my API call but I am not quite sure how to dynamically get the JSON response into the Ens.Response Object with its lists of Arrays that I have defined.

set tSC = ..Adapter.SendFormDataArray(.tHTTPResposne,"POST",tHTTPRequest,,,tURL)

Hi,

Hello everyone!
I need to build something that will receive a REST request. As of now I have tried my luck with using an EnsLib.HTTP.InboundAdapter. But i am not so sure how I am supposed to configure it to be able to receive the REST request together with the JSON body.
I have specified the OnProcessInput in the adapter so that it receives a GlobalCharacterStream. However, I have not had any good luck finding out to actually make the request to the EnsLib.HTTP.InboundAdapter.

After installing IRIS 2023.1 on a live copy of our production machine our REST Service now consumes a CSP Session with every request. The request is handled as expected, but uses one of the 5 CSP Session per license. So after 25 requests, the license is used up. The Grace time always shows 0 and the session stay for very long. (Maybe the 900 Seconds timeout).
On Caché 2018, we had the same settings for the Webapp and there, only a single Session was set for all requests. The Caché request didn't use any cookies.

It is clear how to get the request header value with a specific name:

Class My.RestController Extends %CSP.REST
{

ClassMethod processRequest() As %Status
{
    #dim request as %CSP.Request 
    set request = %request
    set h = ##class(%REST.Impl).%GetHeader("...")
    ...    
    return $$$OK
}

But I can't figure out how to enumerate ALL the request headers (and also get all values).

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.

Hi,

I have a scenario where I recognize that I have a duplicate patient in FHIR , both have a different set of data attached to them (Specimens / Observations / Conditions) and I want to transfer all the data from patient X to patient Y, and maybe mark patient X as not relevant or delete it IDK yet.

since Patch currently supports only single patch,

"The Conditional Patch query identified more than one resource."

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)

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.

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.

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.

Good morning:


Thank you very much for reading the doubt and above all thank you very much for answering.

Given the following use case:

If we have a Destination Service that through a HTTP GET by REST gives us a certain JSON response, where it should be noted that it is a list of objects where each object in the list does NOT have a key:

I built my rest api with ^%REST and update with CreateApplication.
Postman works fine and I suppose production server will work fine as UI and rest api will be on the same domain, but for now in dev, I need to have access from my local to the Iris rest api. I have a CORS error.

I do not know how to configure my swagger file to have either Parameter HandleCorsRequest=1 or <route Cors=true in the generated displ,cls.

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.

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
