Thanks Marc Mundt for your reply

Yes you are right, we should use POST

We have changed it:

<Route Url="/consultarImagen" Method="POST" Call="consultarImagen"/>

However we do not see the response in POSTMAN:

And the headers are:

Content-Type: text/html

Content-Length: 0

CACHE-CONTROL: no-cache

PRAGAM: no-cache

We send the POST to the following URL:

http://localhost:19622/aplicaciones/scs/test/miscs/consultarImagen
 

Besides we observe the response message being converted from Ensemble object to JSON in the service:

We do see the Response Message from the Operation to the Service

Why we do not see the JSON being replied from the Service in POSTMAN?

How could we debug this behaviour?

Thanks for your replies

Thanks Marc Mundt for your help,

We have tried to make objetoSalida.binario as %Binary

Exactly we do the following:

1) We read the image as binary directly from the external system in the REST Operation:

set linea=""
    if (tResponse.Data.AtEnd = 0) {
        set linea = tResponse.Data.Read()
    }
    
    set pResponse.binario = linea
    
    $$$LOGINFO("pResponse.binario: "_pResponse.binario)

We observe the binary correctly written in the LOGINFO:

2) In the Service, we have a LOGINFO  before writing it to JSON

 $$$LOGINFO("objetoSalida.binario: "_objetoSalida.binario)        

 set tSC = claseAux.%WriteJSONStreamFromObject(.pOutput,.objetoSalida,,,,"aeloqtuw")

We see it correctly:

3) However when we convert it to JSON we see that there are strange characters like "\x00"

set tSC = claseAux.%WriteJSONStreamFromObject(.pOutput,.objetoSalida,,,,"aeloqtuw")

$$$LOGINFO("pOutput.Read(): "_pOutput.Read())

How would you recommend us to continue?

What documents or code examples would you study or write to handle this issue?

Thanks for your help

Hello,

We have continued the development,

The output system now replies to us

However we do see that the 2nd MIME part, the image, is being sent from ENSEMBLE, different than the image sent with POSTMAN

1 Let's see what we send from Ensemble:

2 The following image show us what POSTMAN correctly sends:

If we examine and compare both images, we observe that the image sent with Postam is being recognized as a JPEG, however the one sent with Ensemble is not being sent as a JPEG

The code which we have written is:

Hello,

Thanks Marc Mundt for your help,

1 We have tried with the following code which reads a String which represents an image in pRequest.imagen and we send it into a MIME:

Class Operaciones.REST.miSCS.miSCSSubirImagenJPGlocal Extends EnsLib.REST.Operation { Parameter INVOCATION = "Queue";

/// 📤 Subir la imagenSanitaria
Method SubirImagen(pRequest As Mensajes.Request.miSCS.SubirImagen, pResponse As Mensajes.Response.miSCS.SubirImagen) As %Library.Status
{
    
    Set httpRequest=##class(%Net.HttpRequest).%New()
    set tResponse = ##class(%Net.HttpResponse).%New()
    
    Set msg=##class(%Net.MIMEPart).%New()
     Set msg.Body=##class(%GlobalCharacterStream).%New()
    Do msg.Body.Write(pRequest.imagen)
    Set msg.ContentType="multipart/form-data"
    
    // create MIME writer; write root MIME message
    Set writer=##class(%Net.MIMEWriter).%New()

    // Prepare outputting to the HttpRequestStream
    Set status=writer.OutputToStream(httpRequest.EntityBody)
    if $$$ISERR(status) {do $SYSTEM.Status.DisplayError(status) Quit}

    // Now write down the content
    Set status=writer.WriteMIMEBody(msg)
    if $$$ISERR(status) {do $SYSTEM.Status.DisplayError(status) Quit}
    
    set url      = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","url")
    set path     = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","path")
    set servicio = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","servicio")
    set recurso  = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","subirImagen")
            
    set URL = "http://"_url_path_servicio_recurso
    $$$LOGINFO("URL: "_URL)

    set tFormVarNames = "expediente,imagen"
    set tData("expediente") = pRequest.expediente
    set tData("imagen") = pRequest.imagen

    set tSC = ..Adapter.SendFormDataArray(.tResponse,"POST",httpRequest,.tFormVarNames,.tData,URL)
    $$$LOGINFO("tSC: "_tSC)
    
    if $$$ISERR(tSC){
            $$$ThrowOnError(tSC)
    }
    if (tResponse.Data.AtEnd = 0) {
        $$$LOGINFO("En SubirImagen, tamaño de tResponse: "_tResponse.Data.Size)
        set linea = tResponse.Data.Read()
        $$$LOGINFO("Linea: "_linea)
    }
    
    set pResponse = ##class(Mensajes.Response.miSCS.SubirImagen).%New()
    do pResponse.return.Write(linea)

    Quit pResponse
}

However when we see it using Whireshark we observe that it is being sent as text/html

2 We have also used the following approach, to read a JPG directly and send it into the MIME:

Class Operaciones.REST.miSCS.miSCSSubirImagenJPGlocal Extends EnsLib.REST.Operation
{

Parameter INVOCATION = "Queue";

/// 📤 Subir la imagenSanitaria
Method SubirImagen(pRequest As Mensajes.Request.miSCS.SubirImagen, pResponse As Mensajes.Response.miSCS.SubirImagen) As %Library.Status
{
    
    //Crear Request y Response HTTP
    Set httpRequest=##class(%Net.HttpRequest).%New()
    set tResponse = ##class(%Net.HttpResponse).%New()
    
    //Crear MIME
    Set msg=##class(%Net.MIMEPart).%New()
     Set msg.Body=##class(%GlobalCharacterStream).%New()
     
    //Probamos a leer una imagen local y a enviarla
    Set stream=##class(%Stream.FileCharacter).%New()
      Set sc=stream.LinkToFile("C:\Users\ext-ymorjim\Pictures\miSCS.jpg")
      While 'stream.AtEnd {
          Set linea=stream.Read()
      }
      $$$LOGINFO("linea: "_linea)
      
      //Escribir la imagen en el mensaje MIME
     Do msg.Body.Write(linea)
    //Do msg.Body.Write(pRequest.imagen)
    Set msg.ContentType="multipart/form-data"
    
    // create MIME writer; write root MIME message
    Set writer=##class(%Net.MIMEWriter).%New()

    // Prepare outputting to the HttpRequestStream
    Set status=writer.OutputToStream(httpRequest.EntityBody)
    if $$$ISERR(status) {do $SYSTEM.Status.DisplayError(status) Quit}

    // Now write down the content
    Set status=writer.WriteMIMEBody(msg)
    if $$$ISERR(status) {do $SYSTEM.Status.DisplayError(status) Quit}
    

    set url      = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","url")
    set path     = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","path")
    set servicio = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","servicio")
    set recurso  = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","subirImagen")
            
    set URL = "http://"_url_path_servicio_recurso
    $$$LOGINFO("URL: "_URL)

    set tFormVarNames = "expediente,imagen"
    set tData("expediente") = pRequest.expediente
    set tData("imagen") = pRequest.imagen
    //set tData("imagen") = linea

    set tSC = ..Adapter.SendFormDataArray(.tResponse,"POST",httpRequest,.tFormVarNames,.tData,URL)
    $$$LOGINFO("tSC: "_tSC)
    
    if $$$ISERR(tSC){
            $$$ThrowOnError(tSC)
    }
    if (tResponse.Data.AtEnd = 0) {
        $$$LOGINFO("En SubirImagen, tamaño de tResponse: "_tResponse.Data.Size)
        set linea = tResponse.Data.Read()
        $$$LOGINFO("Linea: "_linea)
    }
    
    set pResponse = ##class(Mensajes.Response.miSCS.SubirImagen).%New()
    do pResponse.return.Write(linea)

    Quit pResponse
}

With the previous code we see that a text/html is being sent too:

In both cases, the external system gives us a HTTP code 400:

     ERROR <Ens>ErrException: <THROW>zSubirImagen+40^Operaciones.REST.miSCS.miSCS.1 *%Exception.StatusException ERROR <Ens>ErrHTTPStatus: Received non-OK status 400 from remote HTTP server: 'HTTP/1.1 400 ' -- logged as '-' number - @' Set sc=tSC Throw:('sc) ##class(%Exception.StatusException).ThrowIfInterrupt(sc)'

How could we achieve to send it in the correct way? as it is being sent when we use POSTMAN:

How could we send the image as multipart/form-data?

https://docs.intersystems.com/irisforhealthlatest/csp/docbook/Doc.View.c...

How could we send the image as multipart/form-data as it is being sent by Postman?

➡️ Could you point us to same code examples, please?

Hello Kevin,

Yes you were right we did not include "/opt/contenedor/Java/AppSeguimientoAnadidaReferenciaJARSexternos.jar"

We have just added it and the exception continues.

Hello Eduard

We would need to be able to send a REST POST meesage with the following body:

{
"provider":"provider",
"group""group",
"location""location",
"data""data",
"checkin""checkin",
"client""client",
"admin""admin",
"apiUrl""apiUrl"
}
 
 

And get the previous body inside our Service.

We have written as a Service:

Class Servicios.REST.HistoriaClinica.Videoconsulta Extends Ens.BusinessService
{ Parameter ADAPTER = "EnsLib.HTTP.InboundAdapter"; Method OnProcessInput(pInput As %RegisteredObject, Output pOutput As %RegisteredObject) As %Status
{
do ..enviarCitaCrearSala(pInput,.pOutput)
quit $$$OK
} Method enviarCitaCrearSala(pInput As %Stream.Object, Output pOutput As %Stream.Object) As %Status
{
//TODO: Get body


set tSC = ..SendRequestSync("Videoconsulta",body,.objetoSalida)
set claseAux = ##class(%ZEN.Auxiliary.jsonProvider).%New()
set tSC = claseAux.%WriteJSONStreamFromObject(.pOutput,.objetoSalida,,,,"aeloqtuw")

Quit tSC
}

Inspired by Cristiano Silva's answer, we have found the following way to get the desired property:

..%Process.%CurrentResponseHeader.SourceConfigName

Helo Alexey, Eduard:

There will be dozens of files every day. We also think that we should do it through a linux shell script, which:

1º Detects the files modified (or created) on the last day, in a series of folders (which will be in the same directory)

2º Copy the files to the folder "internal to the server" (we need to copy them and not just move them, because the original file must be recorded because they are owned by a different system)

How would you approach the shell script? We appreciate your time

Hello Eduard Lebedyuk, thanks for your answer.

We have tried to send two async calls, and then use a <sync> to wait for both responses. We thought the BPL execution flow would stop at <sync> until it gets all responses from the async calls. However we observe that both sync calls are sent and then the execution flow continues beyond <sync>.

To give more context, we are calling for specialists appointments, then for primary appointments, after that we have the sync, and finally some transformation and code as follows:

Being the trace, the following, where we see the two asyn call being sent:

However because of the execution flow continues after <sync> without having both responses, we have in our context empty responses, so then the transformation fails:

Besides we do get the responses, however they arrive after they are needed, because of primary appointments return after the Transform attempt was made, and the specialists appointments are retrieved after BPL sends a response to the service (which means we could not use the specialists appointments anymore).

The question is: how could we achieve to wait and stop BPL execution flow, until we do get both async calls' responses?
