Sending a request as "multipart/related"

Hi,   I have a requirement to send a multipart SOAP message, with attachment, to a HTTP endpoint as POST.   The endpoint I am sending to requires I use the multipart/related Content-Type header (...

May be you can try removing the existing attachment and attach the same again to see if that helps.

Hi Rao,

 

Thanks for all your replies and suggestions. I think I have figured out a workaround for this issue. It's very hacky though.

 

I realised I can set the Request window to hold the entire message I want to send, including attachment data and boundaries. I can then set the Content Type" header manually (ie through a groovy script) to point to the same boundary that I already know is in the request.

 

So for example I set the request window as

 

--KambGd0qv9bPTqokGRMcrgDlCZ7kvKx5
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: binary
Content-ID: <ROOTPART>

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <SOAP-ENV:Body>

//----
// SOAP Body XML Here
//----

    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

--KambGd0qv9bPTqokGRMcrgDlCZ7kvKx5
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: binary
Content-ID: <8639147c-2e83-4209-91fa-320eb20a2fcf>

//----
//Attachment data here (eg content of another XML file)
//----

--KambGd0qv9bPTqokGRMcrgDlCZ7kvKx5--

Then I set the Content-Type header as

 

multipart/related; boundary="KambGd0qv9bPTqokGRMcrgDlCZ7kvKx5"; type="text/xml";start="<ROOTPART>"

And the request is sent with the MIME header information I want, and the attachments in the right place:

POST http://localhost:8280/ab/service/dri HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: multipart/related; boundary="KambGd0qv9bPTqokGRMcrgDlCZ7kvKx5"; type="text/xml";start="<ROOTPART>";charset=UTF-8
Content-Transfer-Encoding: binary
Content-Length: 5763
Host: localhost:8280
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

 

Not the most graceful way to do it, but it works for my use case.

 

Thanks again for your help Rao.

 

Regards,

Dave
