The form-data is actually resides in MimeData property and the query parameters are in Data property in %request object. You can you use GetMimeData method to retrieve a single from-data or use NextMimeData  for series fetch and The form-data value is in the form of stream. Get method is used to get query parameters from the %request.


ClassMethod SampleCode() As %Status
{
	write "query parameter: ",%request.Get("testParam")
	set mime=""
	while 1{
		set mime = %request.NextMimeData(mime) q:mime=""
		write mime,!
	}
	return $$$OK
}

Hello @Nimisha Joseph 

Can you try the below

XData BPL [ XMLNamespace = "http://www.intersystems.com/bpl" ]
{
<process language='objectscript' request='Ens.Request' response='Ens.Response' height='2000' width='2000' >

}

Hello @Michael Wood 

If those values are not part of the response. Then don't need to worry about it. Code will skip by default. Incase if the property is not defined . Then you have to declare the %JSONIGNOREINVALIDFIELD value as 1 to prevent from that ERROR #9406: Unexpected format for value of field.

Parameter %JSONIGNOREINVALIDFIELD As BOOLEAN = 1;

Hello @Enrico Parisi 

That's right, However Instead of creating a custom datatype to fix this. create/use the auto generated method for that property "OPDTLogicalToXSD" and implement the code logic.

ClassMethod OPDTLogicalToXSD(%val As %TimeStamp) As %String [ ServerOnly = 1 ]
{
	Set %val=##class(%Library.TimeStamp).LogicalToXSD(%val)
	Quit $translate(%val,"TZ"," ")
}

Hello @water huang 

As You can create a class method with name of your property " OPDTLogicalToXSD" and add the code conversion for the datetime as mentioned by @Enrico Parisi at XML export time.

It's suitable for both XML and JSON adaptor.

Sample code.

Class Samples.NewClass2 Extends (%Persistent, %Populate, %JSON.Adaptor, %XML.Adaptor)
{
Property OPDT As %Library.DateTime;

ClassMethod OPDTLogicalToXSD(%val As %TimeStamp) As %String [ ServerOnly = 1 ]
{
	Set %val=##class(%Library.TimeStamp).LogicalToXSD(%val)
	Quit $translate(%val,"TZ"," ")
}
}

output

 <NewClass2><OPDT>2023-11-30 11:07:02</OPDT></NewClass2>

Hello @Michael Wood

It won't allow to import the array values directly from the response/payload If you're using %JSONImport  in %JSON.Adaptor due to the datatype validation while import. So, You may define the list of properties in separate class definition and use that Property Messages As list of class if the array has object values and It allows to import. Or if it's literal string inside an array then it allows without any issues. 

Sample: Literal string values inside array

Class Samples.NewClass2 Extends (%Persistent, %Populate, %JSON.Adaptor)
{

Property email As list Of %String;

Parameter %JSONIGNOREINVALIDFILED = 1;

Property FirstName As %String;

Property LastName As %String;

ClassMethod test()
{
    set json={"FirstName":"test","LastName":"lastname","email":["test@gmail.com","test2@gmail.com"]}
    set obj= ..%New()
    set st= obj.%JSONImport(json)
    if $$$ISERR(st) write $SYSTEM.OBJ.DisplayError(st)
    write obj.%JSONExport()
}

}

output

LEARNING>d ##Class(Samples.NewClass2).test()
{"email":["test@gmail.com","test2@gmail.com"],"FirstName":"test","LastName":"lastname"}

Hello @Nimisha Joseph 
As per you're SQL implementation. It's actually straightforward and you took and store "Forename" and "Surname" in to context.  haven't taken any SQL resultset object to loop. You can execute only embedded sql in the <sql> BPL element.

So, If you want to execute the query you can assign the SQL object by using <assign> or you can use code block to write executable codes. I have added some sample code below for reference.

  • Assign the SQL result set object to context variable
  • while the result set
    • process and result and do your implementation
/// BPL Definition
XData BPL [ XMLNamespace = "http://www.intersystems.com/bpl" ]
{
<process language='objectscript' request='Ens.Request' response='Ens.Response' height='2000' width='2000' >
<context>
<property name='Forename' type='%String' instantiate='0' >
<parameters>
<parameter name='MAXLEN'  value='50' />
</parameters>
</property>
<property name='Surname' type='%String' instantiate='0' >
<parameters>
<parameter name='MAXLEN'  value='50' />
</parameters>
</property>
<property name='ReportDiscipline' type='%String' instantiate='0' >
<parameters>
<parameter name='MAXLEN'  value='50' />
</parameters>
</property>
<property name='tResult' type='%SQL.StatementResult' instantiate='0' />
</context>
<sequence xend='200' yend='950' >
<trace name='TEMP trace element' value='"In business process "_request.StringValue' xpos='200' ypos='250' />
<assign property="context.ReportDiscipline" value="request.StringValue" action="set" xpos='200' ypos='350' />
<trace value='"ReportDiscipline value: "_context.ReportDiscipline' xpos='200' ypos='450' />
<assign property="context.tResult" value="##Class(%SQL.Statement).%ExecDirect(,&quot;select * from table&quot;)" action="set" xpos='200' ypos='550' />
<while condition='context.tResult.%Next()' xpos='200' ypos='650' xend='200' yend='450' >
<assign property="context.surname" value="context.tResult.%Get(&quot;surname&quot;)" action="set" xpos='200' ypos='250' />

</process>
}

Hello @Colin Brough 

Can you try is this approach is suitable. Create a Business Service with Ens.InboundAdapter or without adapter. Call your BPL process as usual interoperability production flow.  Eventually Create your custom Task and invoke your Business service from the OnTask Inherited Method

Class HL7Task.Test Extends %SYS.Task.Definition
{
Method OnTask() As %Status
{
    Set status =  $$$OK
    Try {
        #dim service As Ens.BusinessService 
        Set status = ##class(Ens.Director).CreateBusinessService("HL7.Feed.TriggerService",.service)
        if $isobject(service) {
            do service.OnProcessInput(pInput,.pOutpt)
        }
    }
    Catch(ex) {
        Set status = ex.AsStatus()
    }
    return status
}
}

Business service

Class HL7.Feed.TriggerService Extends Ens.BusinessService
{

Parameter ADAPTER = "Ens.InboundAdapter";
Property TargetConfigName As Ens.DataType.ConfigName;
Parameter SETTINGS = "TargetConfigName:Basic";
Method OnProcessInput(pInput As %RegisteredObject, Output pOutput As %RegisteredObject) As %Status
{
	Do ..SendRequestSync(..TargetConfigName,pInput,.pOutput)
	Quit $$$OK
}

}

Hi @Prasanth Annamreddy 
If you're using Interoperability production to publish your FHIR resources. Then you may instantiate the object for the class HS.FHIRServer.Interop.Request to process the request and production expects this object as a input . Otherwise it will throw "ERROR <Ens>ErrRequestNotHandled: Request message not handled"
