NAME
SOAP::WSDL - SOAP with WSDL support
NOTICE
This module is not recommended for new application development. Please use XML::Compile::SOAP or
SOAP::Lite instead if possible.
This module has a large number of known bugs and is not being actively developed. This 3.0 release is
intended to update the module to pass tests on newer Perls. This is a service to existing applications
already dependent on this module.
SYNOPSIS
my $soap = SOAP::WSDL->new(
wsdl => 'file://bla.wsdl',
);
my $result = $soap->call('MyMethod', %data);
DESCRIPTION
For creating Perl classes instrumenting a web service with a WSDL definition, read SOAP::WSDL::Manual.
For using an interpreting (thus slow and somewhat troublesome) WSDL based SOAP client, which mimics
SOAP::Lite's API, read on.
Creating Interface classes is the recommended usage.
Did I say you should create interface classes following the steps in SOAP::WSDL::Manual?
If you're migrating from earlier versions of SOAP::WSDL, you should read the MIGRATING documentation.
The stuff below is for users of the 1.2x SOAP::WSDL series. All others, please refer to
SOAP::WSDL::Manual
SOAP::WSDL provides easy access to Web Services with WSDL descriptions.
The WSDL is parsed and stored in memory.
Your data is serialized according to the rules in the WSDL.
The only transport mechanisms currently supported are http and https.
METHODS
new
Constructor. All parameters passed are passed to the corresponding methods.
call
Performs a SOAP call. The result is either an object tree (with outputtree), a hash reference (with
outputhash), plain XML (with outputxml) or a SOAP::SOM object (with neither of the above set).
call() can be called in different ways:
• Old-style idiom
my $result = $soap->call('method', %data);
Does not support SOAP header data.
• New-style idiom
my $result = $soap->call('method', $body_ref, $header_ref );
Does support SOAP header data. $body_ref and $header ref may either be hash refs or
SOAP::WSDL::XSD::Typelib::* derived objects.
Result headers are accessible via the result SOAP::SOM object.
If outputtree or outputhash are set, you may also use the following to access response header data:
my ($body, $header) = $soap->call('method', $body_ref, $header_ref );
wsdlinit
Reads the WSDL file and initializes SOAP::WSDL for working with it.
Is called automatically from call() if not called directly before.
servicename
portname
call
You may set servicename and portname by passing them as attributes to wsdlinit:
$soap->wsdlinit(
servicename => 'MyService',
portname => 'MyPort',
);
CONFIGURATION METHODS
outputtree
When outputtree is set, SOAP::WSDL will return an object tree instead of a SOAP::SOM object.
You have to specify a class_resolver for this to work. See class_resolver
class_resolver
Set the class resolver class (or object).
Class resolvers must implement the method get_class which has to return the name of the class name for
deserializing a XML node at the current XPath location.
Class resolvers are typically generated by using the generate_typemap method of a SOAP::WSDL::Generator
subclass.
Example:
XML structure (SOAP body content):
<Person>
<Name>Smith</Name>
<FirstName>John</FirstName>
</Person>
Class resolver
package MyResolver;
my %typemap = (
'Person' => 'MyPersonClass',
'Person/Name' => 'SOAP::WSDL::XSD::Typelib::Builtin::string',
'Person/FirstName' => 'SOAP::WSDL::XSD::Typelib::Builtin::string',
);
sub get_class { return $typemap{ $_[1] } };
1;
You'll need a MyPersonClass module in your search path for this to work - see
SOAP::WSDL::XSD::ComplexType on how to build / generate one.
servicename
$soap->servicename('Name');
Sets the service to operate on. If no service is set via servicename, the first service found is used.
Returns the soap object, so you can chain calls like
$soap->servicename->('Name')->portname('Port');
portname
$soap->portname('Name');
Sets the port to operate on. If no port is set via portname, the first port found is used.
Returns the soap object, so you can chain calls like
$soap->portname('Port')->call('MyMethod', %data);
no_dispatch
When set, call() returns the plain request XML instead of dispatching the SOAP call to the SOAP service.
Handy for testing/debugging.
ACCESS TO SOAP::WSDL's internals
get_client / set_client
Returns the SOAP client implementation used (normally a SOAP::WSDL::Client object).
EXAMPLES
See the examples/ directory.
Differences to previous versions
• WSDL handling
SOAP::WSDL 2 is a complete rewrite. While SOAP::WSDL 1.x attempted to process the WSDL file on the
fly by using XPath queries, SOAP:WSDL 2 uses a Expat handler for parsing the WSDL and building up a
object tree representing it's content.
The object tree has two main functions: It knows how to serialize data passed as hash ref, and how to
render the WSDL elements found into perl classes.
Yup you're right; there's a builtin code generation facility. Read SOAP::WSDL::Manual for using it.
• no_dispatch
call() with no_dispatch set to true now returns the complete SOAP request envelope, not only the
body's content.
• outputxml
call() with outputxml set to true now returns the complete SOAP response envelope, not only the
body's content.
• servicename/portname
Both servicename and portname can only be called after calling wsdlinit().
You may pass the servicename and portname as attributes to wsdlinit, though.
Differences to previous versions
The following functionality is no longer supported:
Operation overloading
The SOAP standard allows operation overloading - that is, you may specify SOAP operations with more than
one message. The client/server than can choose which message to send. This SOAP feature is usually used
similar to the use of methods with different argument lists in C++.
Operation overloading is no longer supported. The WS-I Basic profile does not operation overloading. The
same functionality as operation overloading can be obtained by using a choice declaration in the XML
Schema.
readable
Readable has no effect any more. If you need readable debug output, copy the SOAP message to your
favorite XML editor and run the source format command. Outputting readable XML requires lots of
programming for little use: The resulting XMl is still quite unreadable.
on_action
Setting on_action is not required any more, the appropriate value is automatically taken from the WSDL.
on_action is a no-op, and is just here for compatibility issues.
Differences to SOAP::Lite
readable
readable is a no-op in SOAP::WSDL. Actually, the XML output from SOAP::Lite is hardly readable, either
with readable switched on.
If you need readable XML messages, I suggest using your favorite XML editor for displaying and
formatting.
Message style/encoding
While SOAP::Lite supports rpc/encoded style/encoding only, SOAP::WSDL currently supports document/literal
style/encoding.
autotype / type information
SOAP::Lite defaults to transmitting XML type information by default, where SOAP::WSDL defaults to leaving
it out.
autotype(1) might even be broken in SOAP::WSDL - it's not well-tested, yet.
Output formats
In contrast to SOAP::Lite, SOAP::WSDL supports the following output formats:
• SOAP::SOM objects.
This is the default. SOAP::Lite is required for outputting SOAP::SOM objects.
• Object trees.
This is the recommended output format. You need a class resolver (typemap) for outputting object
trees. See class_resolver above.
• Hash refs
This is for convenience: A single hash ref containing the content of the SOAP body.
• xml
See below.
outputxml
SOAP::Lite returns only the content of the SOAP body when outputxml is set to true. SOAP::WSDL returns
the complete XML response.
Auto-Dispatching
SOAP::WSDL does does not support auto-dispatching.
This is on purpose: You may easily create interface classes by using SOAP::WSDL::Client and implementing
something like
sub mySoapMethod {
my $self = shift;
$soap_wsdl_client->call( mySoapMethod, @_);
}
You may even do this in a class factory - see wsdl2perl for creating such interfaces.
Debugging / Tracing
While SOAP::Lite features a global tracing facility, SOAP::WSDL allows one to switch tracing on/of on a
per-object base.
This has to be done in the SOAP client used by SOAP::WSDL - see get_client for an example and
SOAP::WSDL::Client for details.
BUGS AND LIMITATIONS
The bug tracker is at <https://rt.cpan.org/Dist/Display.html?Queue=SOAP-WSDL>.
This module is in legacy maintenance mode. Only show stopper bugs are being fixed, until/unless someone
wishes to resume active development on it. Scott Walters, "scott@slowass.net" has obtained co-mainter
from the CPAN admins for the purpose of applying existing fixes people have submit to the RT tracker, and
to apply other fixes as needed to get the module to install and run on newer Perls. Non show-stopper
bugs reports without fixes will be added to this list of limitations. Of course, fixes for these and
other bugs are welcome. Scott does not get email from rt.cpan.org, so please drop an email to him at
"scott@slowass.net" if you open a ticket there.
• Breaks the idiom "$package->can("SUPER::method")" in your code
If you redefine "UNIVERSAL::can()", and someone tries to do "$package->can("SUPER::method")", it'll
look at your packages @ISA, not theirs. This module does precicely that, by way of its dependency on
"Class::Std::Fast".
• $obj == undef does not work in perl 5.8.6 and perl 5.8.7
Due to some strange behaviour in perl 5.8.6 and perl 5.8.7, stringification overloading is not
triggered during comparison with undef.
While this is probably harmless in most cases, it's important to know that you need to do
defined( $obj->get_value() )
to check for undef values in simpleType objects.
• perl 5.8.0 or higher required
SOAP::WSDL needs perl 5.8.0 or higher. This is due to a bug in perls before - see
http://aspn.activestate.com/ASPN/Mail/Message/perl5-porters/929746 for details.
• Apache SOAP datatypes are not supported
You can't use SOAP::WSDL with Apache SOAP datatypes like map.
• Incomplete XML Schema definitions support
This section describes the limitations of SOAP::WSDL, that is the interpreting SOAP client. For
limitations of wsdl2perl generated SOAP clients, see SOAP::WSDL::Manual::XSD.
XML Schema attribute definitions are not supported in interpreting mode.
The following XML Schema definitions varieties are not supported in interpreting mod:
group
simpleContent
The following XML Schema definition content model is only partially supported in interpreting mode:
complexContent - only restriction variety supported
See SOAP::WSDL::Manual::XSD for details.
• Serialization of hash refs does not work for ambiguous values
If you have list elements with multiple occurrences allowed, SOAP::WSDL has no means of finding out
which variant you meant.
Passing in item => [1,2,3] could serialize to
<item>1 2</item><item>3</item>
<item>1</item><item>2 3</item>
Ambiguous data can be avoided by providing data as objects.
• XML Schema facets
Almost no XML schema facets are implemented. The only facets currently implemented are:
fixed
default
The following facets have no influence:
minLength
maxLength
minInclusive
maxInclusive
minExclusive
maxExclusive
pattern
enumeration

Related projects
• SOAP::Lite
Full featured SOAP-library, little WSDL support. Supports rpc-encoded style only. Many protocols
supported.
• XML::Compile::SOAP
Creates parser/generator functions for SOAP messages. Includes SOAP Client and Server
implementations. Can validate XML messages.
You might want to give it a try, especially if you need to adhere very closely to the XML Schema /
WSDL specs.
