NAME

XML::Compile::SOAP::Server - server-side SOAP message processing

INHERITANCE

XML::Compile::SOAP::Server is extended by
  XML::Compile::SOAP11::Server
  XML::Compile::SOAP12::Server

SYNOPSIS

# used by distribution XML::Compile::SOAP::Daemon

my $soap   = XML::Compile::SOAP11::Server->new;
my $input  = $soap->compileMessage('RECEIVER', ...);
my $output = $soap->compileMessage('SENDER', ...);

$soap->compileHandler
  ( name => $name, input => $input, output => $output
  , callback => \$my_handler
  );

my $daemon = XML::Compile::SOAP::HTTPDaemon->new(...);
$daemon->addHandler($type => $daemon);

DESCRIPTION

This class defines methods that each server for the SOAP message exchange protocols must implement.

METHODS

Instantiation

This object can not be instantiated, but is only used as secundary base class. The primary must contain the new.

XML::Compile::SOAP::Server->new(OPTIONS)

-Option--Default
 role    'NEXT'

role => URI

In SOAP1.1, the term is 'actor', but SOAP1.2 has renamed this into 'role': the role [this daemon] plays in the transport protocol.

Please use the role abbreviations as provided by the protocol implementations when possible: they will be translated into the right URI on time. See XML::Compile::SOAP::roleAbbreviation() and the constants defined in XML::Compile::SOAP::Util

Accessors

$obj->role()

Returns the URI of the role (actor) of this server.

Actions

$obj->compileFilter(OPTIONS)

This routine returns a CODE reference which can be used for compileHandler(selector); so see whether a certain message has arrived. On the moment, only the first body element is used to determine that.

-Option--Default
 body    []
 fault   <undef>
 header  <undef>

body => ARRAY-of-TYPES

fault => ARRAY-of-TYPES

header => ARRAY-of-TYPES

$obj->compileHandler(OPTIONS)

Returns an HTTP status code and an XML::LibXML::Document pair.

-Option  --Default
 callback  <fault: not implemented>
 decode    <undef>
 encode    <undef>
 name      <required>
 selector  sub {0}

callback => CODE

As input, the SERVER object and the translated input message (Perl version) are passed in. As output, a suitable output structure must be produced. If the callback is not set, then a fault message will be returned to the user.

decode => CODE

The CODE reference is used to decode the (parsed) XML input message into the pure Perl request. The reference is a READER, created with XML::Compile::Schema::compile(). If no input decoder is specified, then the callback handler will be called with the un-decoded XML::LibXML::Document node.

encode => CODE

The CODE reference is used to encode the Perl answer structure into the output message. The reference is a WRITER. created with XML::Compile::Schema::compile(). If no output encoder is specified, then the callback must return an XML::LibXML::Document, or only produce error messages.

name => STRING

The identification for this action, for instance used for logging. When the action is created via a WSDL, the portname will be used here.

It is a pitty that the portname is not passed in the SOAP message, because it is not so easy to detect which handler must be called.

selector => CODE

One way or the other, you have to figure-out whether a message addresses a certain process. The callback will only be used if the CODE reference specified here returns a true value.

The CODE reference will be called with the XML version of the message, and a HASH which contains the information about the XML collected with XML::Compile::SOAP::messageStructure() plus the soap_version entry.

XML::Compile::SOAP::Server->faultWriter()

Returns a CODE reference which can be used to produce faults.
