Thanks Julian Matthews for your reply because it is helpful and it let us try to understand a little bit what is happening

How would you recommend or suggest to convert a hexadecimal to Ascii?

Would you share an example or documentation with us, please?

Thanks for your time, and it is a great tool to share with us what is happening behind scenes.

If you could points us to some code or functions in ensemble to convert hexadecimal to ascii, it would be great.

Hello Eduard thanks for your reply

msg is a %GlobalCharacterStream

it is defined before, here is the code:

                            set msg=##class(%GlobalCharacterStream).%New()
                            if ('tSC) || (response.error '= "")||(response.informacion.mensaje '= "") {
                                do msg.Write("<br></br><H1>No existe el informe solicitado</H1>")
                            } else {
                                do ..Adapter.AssignOneSetting("Pdf","1","")
                                Do msg.Write($SYSTEM.Encryption.Base64Decode(response.datos.pdf))
                            }

Hello, thanks for your time reading our questions and doubts,

We have studied how to use the following data types: %Stream.TmpCharacter and %Stream.TmpBinary

We have used both as follows:

               

               set pOutput = ##class(%Stream.TmpBinary).%New()
                //set pOutput = msg
                while(msg.AtEnd=0){
                    do pOutput.Write(msg.Read())
                }
                do msg.Clear()
                Quit $$$OK
 
                do pOutput.Clear()
                $$$LOGWARNING("Despues de borrar en el Servicio: pOutput.Clear()")

However we still observing a .stream being created at: /opt/ensemble/ESBHCDSNS/stream

How could we delete a .stream which represents a pdf being returned from a REST Service to POSTMAN?

Thanks for your help 🙇‍♂️  and time reading our questions and code ⌚️

➡️ We would need some help if you could explain to us how would you recommend to delete a .stream in a REST Service? , please.

Thanks Jeffrey for your kind help, and thanks for your time.

We have wrote your method in a class called "Util.FuncionesComunes"

Namespace "ESBSSCC"

We have wrote in the terminal:

ESBSSCC 2e1>Set hosts=##class(Util.FuncionesComunes).GetHostsByAdapter("Producion.ESBSSCC","EnsLib.HTTP.InboundAdapter")
 

We observe:


SET hosts=##class(Util.FuncionesComunes).GetHostsByAdapter("Produccion.ESBSSCC",
^
"EnsLib.HTTP.InboundAdapter")
<COMMAND>^Util.FuncionesComunes.1
ESBSSCC 2e1>

Production's name is: Producion.ESBSSCC

How could we debug this to be able to execute the code and list all REST services in the current namespace?

Thanks for your help, time and replies Jeffrey

Yone Moreno · May 28, 2021

Thanks Jeffrey

We have placed your function in a class called "Util.FuncionesComunes"

We have tried to execute it as follows:

Set hosts=##class(Util.FuncionesComunes).GetHostsByAdapter("Produccion.ESBSSCC","EnsLib.HTTP.InboundAdapter")

It shows:

SET hosts=##class(Util.FuncionesComunes).GetHostsByAdapter("Produccion.ESBSSCC",
^
"EnsLib.HTTP.InboundAdapter")
<COMMAND>^Util.FuncionesComunes.1

When we write: "w $ZERROR" it outputs:

SET hosts=##class(Util.FuncionesComunes).GetHostsByAdapter("Produccion.ESBSSCC",
^
"EnsLib.HTTP.InboundAdapter")
<COMMAND>^Util.FuncionesComunes.1

How could we solve this?

GetAck is a "Method"

How should we call it using method syntax, Marc Mundt?

Thanks for your replies

Yone Moreno · Mar 8, 2021

Thanks Marc Mundt for your attention, and your helpful reply

 
Our current code is:

When we dig deeper using Whireshark:

First, we find that the method in the example that uses GET, the retrievePerson, does answers with a JSON to POSTMAN, so it works:

GET request:

GET response:

In POSTMAN:

However,

Our custom method: consultarImagen which is a POST

Shows nothing in POSTMAN

Why?

POST request:

POST response:

In POSTMAN:

Could you help us?

Thanks for your replies

Yone Moreno · Mar 8, 2021

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

Yone Moreno · Jan 29, 2021

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:

    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)

    set url      = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","url")
    set path     = ##class(Util.TablasMaestras).getValorMaestra("MISCS.PARAMETRIZACIONES","path")

    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)

    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?

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,

We are using the following Java version:

java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

If we execute the command with our jar (which includes the Java program and its dependencies):

jar -tf "AppSeguimientoAnadidaReferenciaJARSexternos.jar"

We see:

If we execute the command to locate the jar where is the class which generates the NoClassDefFoundError :

jar -tf "bcprov-jdk15on-1.58.jar"

We get:

...

org/bouncycastle/util/io/pem/PemObjectParser.class
org/bouncycastle/util/io/pem/PemReader.class
org/bouncycastle/util/io/pem/PemWriter.class
org/bouncycastle/util/test/

...

As you would notice it outputs the name of the missing class:

org/bouncycastle/util/io/pem/PemReader.class

What could we do?

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
}
