SOAP::Transport::HTTP::Daemon and XML

rppowell has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to fake SOAP server functions for testing purposes. I use a the following code as a SOAP client:

SOAP return:

use strict;

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

my $soap = SOAP::Lite
    -> uri('http://www.perlmonks.org/FileQueue')
    -> proxy('http://localhost:88')
    ;

my $rslt = $soap->getServerInfo()->result;
[download]

This generates the following output from the Real SOAP server:

<?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:lwq="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>
[download]

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 $serverinfo;
}

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

This produces the following SOAP response:

<?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>
    <namesp3:getServerInfoResponse xmlns:namesp3="http://www.perlmonks
+.org/FileQueue">
      <s-gensym6 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="namesp2:SOAPStruct">
          <filetype xsi:type="xsd:string">html</filetype>
        </validTypes>
      </s-gensym6>
    </namesp3:getServerInfoResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
[download]

How can I get precise control on the generated XML?

In the Real SOAP response, in the SOAP-ENV:Body, there is <pmq:getServerInfoResponse> node, how do I generate on in the Fake SOAP response?

In some of the XML code, there are xsi:type="xsd:string" values, how do I generate XML without it?

Any help would be appreciated;

Request Copy the real service's WSDL description, then serve it from `http://fakeserver/service?WDSL`. Then you can use SOAP::WSDL to make the request. Because it gets the same WSDL from both services, it will send the same request to both. Response `validTypes` and `statistics` should probably be returned as array refs, rather than hash refs. The main problem seems to be that you're not returning the node name `info` with your data, so SOAP::Lite is using a gensym value. I can't remember exactly the incantation (I mainly deal with .NET services), but try: `return bless { info => $serverinfo }, 'getServerInfoResponse';` -David	[reply] [d/l] [select]

I have the `WSDL` description, but only in file form. Is it necessary that `WSDL` file be web served? I don't see how to use it as local file, is it possible?	[reply] [d/l] [select]

I have the WSDL description, but only in file form. Are you sure? Web-services commonly serve their WSDL from the proxy URL with '?WSDL' appended. The SOAP::Transport::HTTP::Server subclasses don't make it easy to serve your WSDL from the same service, so what I do is the following: use the `HTTP::Request->parse` constructor from HTTP::Request to build a request from the raw incoming request, then (depending on the $request->uri) I either: build a response containing WSDL, or pass $request directly to SOAP::Transport::HTTP::Server like this: `my $soap = SOAP::Transport::HTTP::Server -> new(%args) -> dispatch_to(@classes); $soap->request($request); $soap->handle; my $response = $soap->response;` [download] Is it necessary that `WSDL` file be web served? I don't see how to use it as local file, is it possible? Sure, do something like this: `my $soap = SOAP::WSDL->new(); $soap->wsdl('file:/path/to/file.wsdl'); $soap->proxy('http://server/service.cgi'); $soap->wsdlinit(caching => 1);` [download] Loading from the file saves some time on script startup, using caching saves a lot of work on each request. Update: Fixed my URLs. -David	[reply] [d/l] [select]
