SYNOPSIS

# preparation
use XML::Compile::WSDL11;      # use WSDL version 1.1
use XML::Compile::SOAP11;      # use SOAP version 1.1
use XML::Compile::Transport::SOAPHTTP;

my $wsdl = XML::Compile::WSDL11->new($wsdlfile);
$wsdl->addWSDL(...more WSDL files...);
$wsdl->importDefinitions(...more schemas...);

# during initiation, for each used call (slow)
my $call = $wsdl->compileClient('GetStockPrice', ...);

# at "run-time", call as often as you want (fast)
my $answer = $call->(%request);

# capture useful trace information
my ($answer, $trace) = $call->(%request);

# when you like, get all operation definitions
my @all_ops = $wsdl->operations;

# Install XML::Compile::SOAP::Daemon
my $server  = XML::Compile::SOAP::HTTPDaemon->new;
$server->actionsFromWSDL($wsdl);

# For debug info, start your script with:
use Log::Report mode => 'DEBUG';

DESCRIPTION

This module implements WSDL version 1.1. An WSDL file defines a set of messages to be send and received over (SOAP) connections.

As end-user, you do not have to worry about the complex details of the messages and the way to exchange of them: it's all simple Perl for you. Also faults are handled automatically. The only complication you have to worry about, is to shape a nested HASH structure to the sending message structure. XML::Compile::Schema::template() may help you.

When the definitions are spread over multiple files, you will need to use addWSDL() (wsdl), or importDefinitions() (additional schema's) explicitly, because XML::Compile::Schema does not wish dynamic internet download magic to happen.

METHODS

XML::Compile::WSDL11->new(XML, OPTIONS)

    The XML is the WSDL file, which is anything accepted by XML::Compile::dataToXML(). All options are also passed to create an internal XML::Compile::Schema object. See XML::Compile::Schema::new()

Extension

$obj->addWSDL(XMLDATA)

    Some XMLDATA, accepted by XML::Compile::dataToXML() is provided, which should represent the top-level of a (partial) WSDL document. The specification can be spread over multiple files, which each have a definition root element.

$obj->compileClient([NAME], OPTIONS)

    Creates temporarily an XML::Compile::Operation object with operation(), and then calls compileClient() on that; an usual combination.

    As OPTIONS are available the combination of all possibilities for

    .

    operation() (i.e. service and port), and all of

    .

    XML::Compile::Operation::compileClient() (a whole lot, for instance transport_hook and server), plus

    .

    everything you can pass to XML::Compile::Schema::compile(), for instance check_values => 0, hooks, and typemaps.

    example:

    $wsdl->compileClient
      ( operation => 'HelloWorld'
      , port      => 'PrefillSoap' # only needed when multiple ports
      , sloppy_integers => 1       # X::C::compile() option
      );

$obj->namesFor(CLASS)

    Returns the list of names available for a certain definition CLASS in the WSDL.

$obj->operation([NAME], OPTIONS)

    Collect all information for a certain operation. Returned is an XML::Compile::Operation object.

    An operation is defined by a service name, a port, some bindings, and an operation name, which can be specified explicitly and often left-out (in any situation where there are no alternative choices).

    When not specified explicitly via OPTIONS, each of the CLASSes are only permitted to have exactly one definition. Otherwise, you must make a choice explicitly. There is a very good reason to be not too flexible in this area: developers need to be aware when there are choices, where some flexibility is required.

    Option   --Default
    operation  <required>
    port       <only when just one>
    service    <only when just one>

    . operation => NAME

      Ignored when the parameter list starts with a NAME (which is an alternative for this option). Optional when there is only one operation defined within the portType.

    . port => NAME

      Required when more than one port is defined.

    . service => QNAME

      Required when more than one service is defined.

Introspection

All of the following methods are usually NOT meant for end-users. End-users should stick to the operation() and compileClient() methods.

$obj->findDef(CLASS, [QNAME|NAME])

    With a QNAME, the HASH which contains the parsed XML information from the WSDL template for that CLASS-NAME combination is returned. Otherwise, NAME is considered to be the localName in that class. When the NAME is not found, an error is produced.

    Without QNAME in SCALAR context, there may only be one such name defined otherwise an error is produced. In LIST context, all definitions in CLASS are returned.

$obj->index([CLASS, [QNAME]])

    With a CLASS and QNAME, it returns one WSDL definition HASH or undef. Returns the index for the CLASS group of names as HASH. When no CLASS is specified, a HASH of HASHes is returned with the CLASSes on the top-level.

$obj->operations(OPTIONS)

    Return a list with all operations defined in the WSDL.

DETAILS

Initializing SOAP operations via WSDL

When you have a WSDL file, then SOAP is simple. If there is no such file at hand, then it is still possible to use SOAP. See the DETAILS chapter in XML::Compile::SOAP.

The WSDL file contains operations, which can be addressed by name. In this WSDL file, you need to find the name of the port to be used. In most cases, the WSDL has only one service, one port, one binding, and one portType and those names can therefore be omitted. If there is a choice, then you are required to select one explicitly.

use XML::Compile::WSDL11 ();

# once in your program
my $wsdl   = XML::Compile::WSDL11->new('def.wsdl');

# XML::Compile::Schema does not want to follow "include" and
# "import" commands, so you need to invoke them explicitly.
# $wsdl->addWSDL('file2.wsdl');            # optional
# $wsdl->importDefinitions('schema1.xsd'); # optional

# once for each of the defined operations
my $call   = $wsdl->compileClient('GetStockPrice');

# see XML::Compile::SOAP chapter DETAILS about call params
my $answer = $call->(%request);

DIAGNOSTICS

Error: cannot find pre-installed name-space files

    Use $ENV{SCHEMA_LOCATION} or new(schema_dirs) to express location of installed name-space files, which came with the XML::Compile distribution package.

Error: don't known how to interpret XML data
