Setting XML prefix for tags with SOAP::Lite

[TheFluffyOne]

I'm currently playing around with accessing a WSDL service (RealOps AMP/BMC RBA for those interested) using SOAP::Lite and need to craft a request in the right format.

I managed to find an old post that almost did what I needed and munged the code into the following:

#!/usr/bin/perl -w

use strict;
use SOAP::Lite +trace => 'debug', maptype => {  };

my $userId = "admin";
my $password = "adminpw";

my $wsdl = "http://10.50.50.132:9080/ws/workflow";

my $gridName = SOAP::Header->name("grid-name" => SOAP::Data->type('' =
+> 'SampleGrid1'));
my $rba = SOAP::Lite->uri('urn:realops.com:amp:workflow')->proxy($wsdl
+);

my $wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-ws
+security-secext-1.0.xsd";
my $securityHeader = SOAP::Header->name(
    Security => {
        UsernameToken => {
            Username => SOAP::Data->type('' => $userId)->prefix('wsse'
+),
            Password => SOAP::Data->type('' => $password)->prefix('wss
+e'),
          }
    })->uri($wsse)->prefix('wsse');

my $result = $rba->getAllSOAPServices($gridName, $securityHeader)

This code results in a soap header as follows:

<soap:Header>
    <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/
+oasis-200401-wss-wssecurity-secext-1.0.xsd">
        <UsernameToken>
            <wsse:Password>adminpw</wsse:Password>
            <wsse:Username>admin</wsse:Username>
        </UsernameToken>
    </wsse:Security>
    <grid-name>SampleGrid1</grid-name>
</soap:Header>

The header needs to look like this:

<soapenv:Header>
    <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/
+oasis-200401-wss-wssecurity-secext-1.0.xsd">
        <wsse:UsernameToken>
            <wsse:Username>admin</wsse:Username>
            <wsse:Password>adminpw</wsse:Password>
        </wsse:UsernameToken>
    </wsse:Security>
    <grid-name xmlns="urn:realops.com:amp:workflow">SampleGrid1</grid-
+name>
</soapenv:Header>

How can I get the "wsse" prefix on the UsernameToken tag? I also need to add the xmlns attribute to grid-name, but I haven't finished RTFMing on that one yet...

How can I get the "wsse" prefix on the UsernameToken tag?

my $securityHeader = SOAP::Header->new(
    name   => 'Security',
    uri    => $wsse,
    prefix => 'wsse',
    value  => \SOAP::Data->new(
        name   => 'UsernameToken',
        prefix => 'wsse',
        value  => {
            Username => SOAP::Data->type( '' => $userId )->prefix('wss
+e'),
            Password => SOAP::Data->type( '' => $password )->prefix('w
+sse'),
        }
      )
);

Update: sorry, missed your second issue...

I also need to add the xmlns attribute to grid-name

my $gridName = SOAP::Header->new(
    name   => 'grid-name',
    value  => 'SampleGrid1',
    uri    => 'urn:realops.com:amp:workflow',
    prefix => '',
    type   => '',
);

Fantastic, thanks Altblue. That's exactly what I needed.

With the SOAP call in better shape, I had to work around an issue with the Username and Password being in the wrong order (the WSDL specifies them as a sequence).

I think I just have one more hurdle to overcome. The current version of the script results in the SOAP body:

<soap:Body>
   <DirList xmlns="Test_Module" xsi:nil="true" />
</soap:Body>

But in order to work it seems that it should be:

<soap:Body>
   <tra:DirList />
</soap:Body>

(Where tra is a namespace defined as "Test_Module"). Additionally, I'll want to add a couple of parameters like so:

<soap:Body>
   <tra:DirList>
      <param1>value1</param1>
      <param2>value2</param2>
   </tra:DirList>
</soap:Body>

My recent attempts at adding the parameters have resulted in lots of c-gensym tags added, which I think is an indication that I'm not referencing the data correctly

The code as it currently stands (without the attempt at adding parameters):

#!/usr/bin/perl -w

use strict;
use SOAP::Lite +trace => 'debug', maptype => {  };
use Tie::IxHash;

my $userId = "admin";
my $password = "adminpw";

my %authHash;
tie %authHash, "Tie::IxHash";
%authHash = (
            Username => SOAP::Data->type( '' => $userId )->prefix('wss
+e'),
            Password => SOAP::Data->type( '' => $password )->prefix('w
+sse'),
    );

my $wsdl = "http://10.50.50.132:9080/ws/workflow";

my $rba = SOAP::Lite->uri('Test_Module')->proxy($wsdl);
$rba->on_action(sub { return '"execute-workflow"'; } );

my $wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-ws
+security-secext-1.0.xsd";

my $gridName = SOAP::Header->new(
    name   => 'grid-name',
    value  => 'Amsterdam',
    uri    => 'urn:realops.com:amp:workflow',
    prefix => '',
    type   => '',
);
my $securityHeader = SOAP::Header->new(
    name   => 'Security',
    uri    => $wsse,
    prefix => 'wsse',
    value  => \SOAP::Data->new(
        name   => 'UsernameToken',
        prefix => 'wsse',
        value  => \%authHash
      )
);

my $result = $rba->DirList($gridName, $securityHeader)->result();

print "\n\n\n$result\n";

Well as I was cleaning up my parameter-adding code to post, I had some inspiration and have found a way to do it (though it seems clunky). I have also realised that it wasn't the lack of prefix causing the problem, it was that I was using the wrong method name (d'oh!). New code:

my @params = (
    SOAP::Data->new(
        prefix => '',
        name => 'param1',
        value => SOAP::Data->type('' =>'value1')
        ),
    SOAP::Data->new(
        prefix => '',
        name => 'param2',
        value => SOAP::Data->type('' =>'value2')
        )
    );
my $result = $rba->DirList(@params, $gridName, $securityHeader)->resul
+t();

Which results in:

  <soap:Body>
    <DirList xmlns="Test_Module">
      <param1>value1</param1>
      <param2>value2</param2>
    </DirList>
  </soap:Body>

The tag "DirList" needs to be "DirList-Request", but I can't use this directly in my current code as I get bareword errors...
