SOAP MTOM Attachment

[fedale]

I have this WSDL https://service.pmpay.it/payPA/services/PayPA?wsdl
When call operation "PagamentoEsistenteBollettino" fromZeep it returns something like that, only if I set raw_response:

HTTP/1.1 200 OK
Content-Type: multipart/related; type="text/xml"; start=""; boundary="----=_Part_187_56733036.1531119409567"

[...SNIP...]

Without "raw_response", it will return a NoneType, generating a parse error.

Is there a way to manage this type of response with Zeep?

Thanks in advance

I saw URL-encoded attachment id in some cases. The raw response. And, of course, I got parse error.

I am also facing same issue where my SOAP response contains XML + Binary, Will this patch resolve this issue so that it will extract the attachment
