XML::Compile::SOAP11(3) User Contributed Perl Documentation XML::Compile::SOAP11(3)
 

XML::Compile::SOAP11 - SOAP 1.1 protocol

 XML::Compile::SOAP11 has extra code in
   XML::Compile::SOAP11::Encoding
 XML::Compile::SOAP11
   is a XML::Compile::SOAP
 XML::Compile::SOAP11 is extended by
   XML::Compile::SOAP11::Client
   XML::Compile::SOAP11::Server

 # use either XML::Compile::SOAP11::Client or ::Server
 # See XML::Compile::SOAP for global usage examples.

This module handles the SOAP protocol version 1.1. See http://www.w3.org/TR/2000/NOTE-SOAP-20000508/). The implementation tries to behave like described in http://www.ws-i.org/Profiles/BasicProfile-1.0.html
Two extensions are made: the SOAP11 client XML::Compile::SOAP11::Client. and server in XML::Compile::SOAP11::Server.
Extends "DESCRIPTION" in XML::Compile::SOAP.

Extends "METHODS" in XML::Compile::SOAP.

Extends "Constructors" in XML::Compile::SOAP.

To simplify the URIs of the actors, as specified with the "destination" option, you may use the STRING "NEXT". It will be replaced by the right URI.

You only call compileMessage() explicitly if you do not have a WSDL file which contains this information. In the unlucky situation, you have to dig out the defined types by hand.
But even with a WSDL, there are still a few problems you may encounter. For instance, the WSDL will not contain "mustUnderstand" and "actor" header routing information. You can add these to the compileClient call
  my $call = $wsdl->compileClient
    ( 'MyCall'
    , mustUnderstand => 'h1'
    , destination    => [ h1 => 'NEXT' ]
    );
Simplest form
In the simplest form, the "header" and "body" refer (optionally) to a list of PAIRS, each containing a free to choose unique label and the type of the element. The unique label will be used in the Perl HASH which represents the message.
 my $h1el = pack_type $myns, $some_local;
 my $b1el = 'myprefix:$other_local';
 my $encode_query = $client->compileMessage
   ( 'SENDER'
   , header   => [ h1 => $h1el ]
   , body     => [ b1 => $b1el ]
   , mustUnderstand => 'h1'
   , destination    => [ h1 => 'NEXT' ]
   );
Most powerful form
When the simple form is too simple, you can use a HASH for the header, body or both. The HASH structure is much like the WSDL structure. For example:
 my $encode_query = $client->compileMessage
   ( 'SENDER'
   , header   =>
      { use   => 'literal'
      , parts => [ { name => 'h1', element => $h1el
                   , mustUnderstand => 1, destination => 'NEXT'
                   } ]
      }
   , body     => [ b1 => $b1el ]
   );
So, the header now is one HASH, which tells us that we have a literal definition (this is the default). The optional parts for the header is an ARRAY of HASHes, each describing one part. As you can see, the mustUnderstand and destination fields are more convenient (although the other syntax will work as well).
If you feel the need to control the compilation of the various parts, with hooks or options (see XML::Compile::Schema::compile()), then have a look at XML::Compile::Cache::declare(). Declare how to handle the various types before you call compileMessage().

When faults are received, they will be returned with the "Fault" key in the data structure. So:
  my $answer = $call->($question);
  if($answer->{Fault}) { ... }
As extra service, for each of the fault types, as defined with compileMessage(faults), a decoded structure is included. The name of that structure can be found like this:
  if(my $faults = $answer->{Fault})
  {   my $name    = $faults->{_NAME};
      my $decoded = $answer->{$name};
      ...
  }
The untranslated $faults HASH looks like this:
 Fault =>
   { faultcode => '{http://schemas.xmlsoap.org/soap/envelope/}Server.first'
   , faultstring => 'my mistake'
   , faultactor => 'http://schemas.xmlsoap.org/soap/actor/next'
   , detail => { '{http://test-types}fault_one' => [ XMLNODES ] }
   , _NAME => 'fault1'
   }
The "_NAME" originates from the compileMessage(faults) option:
   $soap->compileMessage('RECEIVER', ...
     , faults => [ fault1 => '{http://test-types}fault_one' ] );
Now, automatically the answer will contain the decoded fault structure as well:
  fault1 =>
    { code => '{http://schemas.xmlsoap.org/soap/envelope/}Server.first'
    , class  => [ 'http://schemas.xmlsoap.org/soap/envelope/'
         , 'Receiver', 'first' ]
    , reason => 'my mistake',
    , role   => 'NEXT'
    , detail => { help => 'please ignore' }
    }
The "detail" is the decoding of the XMLNODES, which are defined to be of type "{http://test-types}fault_one".
The "class" is an unpacked version of the code. SOAP1.2 is using the (better) terms "Sender" and "Receiver".
"role" is constructed by decoding the "faultactor" using roleAbbreviation(). The names are closer to the SOAP1.2 specification.
If the received fault is of an unpredicted type, then the client tries to DWIM. in the worst case, "detail" will list the unparsed XMLNODEs. When the XML::Compile::SOAP::Daemon server has produced the error, the content of the reply will typically be
 { Fault =>        # SOAP version specific
    { _NAME => 'error'
    , #...more...
    }
 , error =>        # less SOAP version specific, readable
    { role    => 'NEXT'
    , reason  => 'procedure xyz for SOAP11 produced an invalid response'
    , error   => 'some explanation'
    , code    =>
        '{http://schemas.xmlsoap.org/soap/envelope/}Server.invalidResponse'
    , class   => [ SOAP11ENV, 'Receiver', 'invalidResponse' ],
    }
  }
Hence, a typical client routine could contain
  my ($answer, $trace) = $call->(message => $message);
  if(my $f = $answer->{Fault})
  {   if($f->{_NAME} eq 'error')
      {   # server implementation error
          die "SERVER ERROR:\n$answer->{error}{error}\n";
      }
      else
      {   # the fault is described in the WSDL, handle it!
          warn "FAULT:\n",Dumper $answer->{$f->{_NAME}};
      }
  }
  else
  {   # correct answer
      print Dumper $answer;
  }
Or
  my ($answer, $trace) = $call->(message => $message);
  $answer or die $trace->error;
