We may need to add the Content-Disposition header in the request and there specify the file name.

In the example we had originally made with SoapUI, that header had this value:

Content-Disposition: attachment; name="application.zip"

Fine Tuning a WebClient tells you how you can specify headers in your web client using the SetHttpHeader() method that inherits from %SOAP.WebClient.

Following the explanation in the documentation, we have added:

do ..SetHttpHeader("Content-Disposition","application.zip")

We have written the line before:

Quit ..WebMethod("cargarFichero","CargarFicheroVacuRequest").Invoke($this,"http://ws.regvacuWs.ms.es/FicheroVacu/cargarFichero",.fichero,.ccaaId,.tipoFichero)

When capturing the LOGSOAP we notice that it is left without including the Content-Disposition header and the name application.zip in what we send:

Why could it be that when writing the line, it is left without including the new Content-Disposition header and the application.zip file name? 💭🤔
 

Also, in other tests, we have written 3 additional ways, to try to solve it:

set ..ContentType="application/octet-stream; name=nombre"

Using the above line, we don't see that it adds the "name" parameter.

We tried the following line and it would generate an Ensemble exception:

set ..HttpRequest.ContentType="application/octet-stream; name=nombre"

ERROR #5001: <INVALID OREF>zcargarFichero+16^WSCLIENTE.HistoriaClinica.FicheroVacuServiceSOAP.1

and using the next line:

do ..HttpRequest.SetHeader("name","nombre")

It gives us exception as well:

<INVALID OREF>zcargarFichero+16^WSCLIENTE.HistoriaClinica.FicheroVacuServiceSOAP.1

The complete class we have written of the Web Service is:

How could we understand, debug, tune, and resolve together, this situation?

If you could give us some guidance, we would appreciate it 🙇🙏🙏🙏🙏🙏

How would you recommend us to follow?

What documentation do we need to study, read, understand, to complete this part?

Thanks for your answers and time reading this question

We have been developing the Web Service following the official documentation:

Using MTOM for Attachments. Webclient

Specifically we have followed an example of a web service client where MTOMRequired property has been activated, and we have also changed the data types to %Stream.

We have written the following WebService:

The target system, asks us to implement a WebService with MTOM to send the zip with a csv inside, as follows:

When importing the WSDL of the target system, the header of the "cargarFichero" (loadFile) method was generated with "fichero" (file) as a "%xsd.base64Binary".

We changed file to "%GlobalCharacterStream".

This way the file, the csv, is sent unencoded, inside a CDATA

Being the response of the target system:

10/15/2021 08:57:24 *********************
Input to Web client with SOAP action = http://ws.regvacuWs.ms.es/FicheroVacu/cargarFichero

However, as we can see in the first image, the target system would need, would require, that we send the file encoded in binary, since it says:

Content-Transfer-Encoding: binary

When we adapt the file to be "%GlobalBinaryStream" we see the following trace, where it is encoded in binary:

When sending binary encoded, the target system also responds:

In short, the target system needs from us:

"add the "name" parameter inside the "Content-Type" header when attaching the file. Your client should generate this parameter to avoid getting this error."

Being the full comparison between what is sent by ensemble (without the "name" parameter, therefore incorrect) on the left; and what is generated by the SoapUI (with the name parameter, correct), on the right:

➡️ Please could you point us to examples, documentation, projects, code, that we can use as a reference to investigate, research and complete the development? 💭

We have also investigated the following answers:

https://community.intersystems.com/post/add-parameter-name-inside-conten...

Thank you very much for your time, reading and responding.

Thanks for your help.

Thanks Jeffrey Drumm for your help, because the answer you have proposed works as expected

In addition you have helped us to learn about the square bracket syntax [] to find a value in a field in all repeating segments

Plus you have shared with us how does it outputs the values of the repeating segments: inside a string where each field's value is inside "<...>"

Thanks
