NAME
XML::Compile::SOAP11 - SOAP 1.1 protocol
INHERITANCE
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
SYNOPSIS
# use either XML::Compile::SOAP11::Client or ::Server
# See XML::Compile::SOAP for global usage examples.
DESCRIPTION
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.

Header and Body entries
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().
Receiving faults in SOAP1.1
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;
