SOAP Server and XML

[rppowell]

I have posted this earlier, see SOAP::Transport::HTTP::Daemon and XML, but I still need help getting SOAP::Lite to return the correct XML information.
This is for a SOAP Server, not the SOAP Client.
Here is the code for the Fake SOAP Server:

use strict;

use SOAP::Lite + "trace";
use SOAP::Transport::HTTP;
use Data::Dumper;

my $serverinfo = {
    version => "0.1.dev",
    validTypes => [
        filetype => "txt",
        filetype => "html",
    ],
    statistics => {
        documentsProcessed => 0,
    },
};

sub FileQueue::getServerInfo {
    return SOAP::Data->name( info => $serverinfo );
}

my $daemon = SOAP::Transport::HTTP::Daemon
    -> new (LocalPort => 88)
    -> dispatch_to('FileQueue')
    ;
print "Contact to SOAP server at ", $daemon->url, "\n";
$daemon->handle;

This is the XML that is generated:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/env
+elope/" xmlns:namesp2="http://xml.apache.org/xml-soap" xmlns:xsi="htt
+p://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENC="http://schema
+s.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/1999/XMLSc
+hema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encodin
+g/">
  <SOAP-ENV:Body>
    <namesp1:getServerInfoResponse xmlns:namesp1="http://www.perlmonks
+.org/FileQueue">
      <info xsi:type="namesp2:SOAPStruct">
        <statistics xsi:type="namesp2:SOAPStruct">
          <documentsProcessed xsi:type="xsd:int">0</documentsProcessed
+>
        </statistics>
        <version xsi:type="xsd:string">0.1.dev</version>
        <validTypes xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="xsd:
+string[4]">
          <item xsi:type="xsd:string">filetype</item>
          <item xsi:type="xsd:string">txt</item>
          <item xsi:type="xsd:string">filetype</item>
          <item xsi:type="xsd:string">html</item>
        </validTypes>
      </info>
    </namesp1:getServerInfoResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I am trying to generate the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/env
+elope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xm
+lns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http:/
+/www.w3.org/1999/XMLSchema" xmlns:pmq="http://www.perlmonks.com/FileQ
+ueue">
  <SOAP-ENV:Body>
    <pmq:getServerInfoResponse>
      <info>
        <version>0.1.dev</version>
        <validTypes>
          <filetype>txt</filetype>
          <filetype>txt</filetype>
        </validTypes>
        <statistics>
          <documentsProcessed>0</documentsProcessed>
        </statistics>
      </info>
    </pmq:getServerInfoResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

How do I get it to generate the XML without the xsi:type attributes?

How do I modify the XML headers? -rppowell

Just reading through the SOAP::Lite gives a few pointers...

I think you can have the "pmq" namespace registered in the SOAP Envelope by doing something like (updated):

  # add this to your service instantiation
  $daemon->envelope(
    register_ns => 'http://www.perlmonks.com/FileQueue', 'pmq');

  # force the 'pmq' prefix to be used
  sub FileQueue::getServerInfo {
    return SOAP::Data->name(info => $serverinfo)->prefix('pmq');
  }

I'm not sure if that's the exact syntax but please have a play around with it (update: if that sets the 'pmq' prefix for 'info' rather than 'getServerInfoResponse', then you probably need to do something at the service level, rather than at the method level).

I don't know how to suppress sending xsi:type attributes for elements inside the SOAP Body.
SOAP::Lite probably allows you to do it... probably with a custom serialiser.

Maybe SOAP::XML::Client would be easier for you.

[erroneousBollock]

I think the OP is looking for help with method result serialisation in his SOAP::Lite server code.

Have you tried this?

SOAP::Data->name( info => $serverinfo )->type('');

I've figured out how to output raw XML into the SOAP envelope:
Read more... PMServer.pl (1043 Bytes)
Using the same client as before:
Read more... PMClient.pl (477 Bytes)
It produces the following SOAP response:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/1999/XMLSchema-instanc
+e" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:S
+OAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http:/
+/www.w3.org/1999/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xm
+lsoap.org/soap/encoding/">
  <SOAP-ENV:Body>
    <namesp1:getServerInfoResponse xmlns:namesp1="http://www.perlmonks
+.org/FileQueue">
      <info>
        <statistics>
          <documentsProcessed>0</documentsProcessed>
        </statistics>
        <validTypes>
          <filetype>html</filetype>
          <filetype>txt</filetype>
        </validTypes>
        <version>0.1.dev</version>
      </info>
    </namesp1:getServerInfoResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This is closer to the real SOAP server response:
Read more... Read SOAP Server Response (1458 Bytes)
I am still trying to figure out how to get rid of the xmlns:namesp1="http://www.perlmonk.org/FileQueue" and the envelope headers.

Ugh, the message was posted when I wasn't logged in.

That'd probably work for the 'info' node, but rppowell wants to (for reasons unknown) strip type attributes from all nodes descending from the Soap::Body.

To do that, it'd need to be done either at the $daemon level, or with a custom(ised?) serialiser.
