call
$soap->call( \%method, \@parts );
%method is a hash with the following keys:
Name Description
----------------------------------------------------
operation operation name
soap_action SOAPAction HTTP header to use
style Operation style. One of (document|rpc)
use SOAP body encoding. One of (literal|encoded)
The style and use keys have no influence yet.
@parts is a list containing the elements of the message parts.
For backward compatibility, call may also be called as below:
$soap->call( $method, \@parts );
In this case, $method is the SOAP operation name, and the SOAPAction header is guessed from the first
part's namespace and the operation name (which is mostly correct, but may fail). Operation style and body
encoding are assumed to be document/literal
Configurationmethodsoutputxml
$soap->outputxml(1);
When set, call() returns the raw XML of the SOAP Envelope.
set_content_type
$soap->set_content_type('application/xml; charset: utf8');
Sets the content type and character encoding.
You probably should not use a character encoding different from utf8: SOAP::WSDL::Client will not convert
the request into a different encoding (yet).
To leave out the encoding, just set the content type without appending charset like this:
$soap->set_content_type('text/xml');
Default:
text/xml; charset: utf8
set_prefix
$soap->set_prefix('ns2');
If set, alters the serialization of the request XML such that the supplied value is used as a namespace
prefix for SOAP method calls. By way of example, the default XML serialization returns something like
this:
<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<getElementId xmlns="http://services.exmaple.org/">
<elementId>12345</elementId>
</getElementId>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
If the sample set_prefix() call above is used prior to calling your SOAP method, the XML serialization
returns this instead:
<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns2="http://services.example.org/">
<SOAP-ENV:Body>
<ns2:getElementId>
<elementId>12345</elementId>
</ns2:getElementId>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
This is useful in cases where, for instance, one is communicating with a JAX
<https://jax-ws.dev.java.net/> webservice, which tends to understand the latter but not the former. Note
that this implementation is currently limited to a single additional namespace; if you require multiple
custom namespaces, you should probably look into creating your own serializer.
FeaturesdifferentfromSOAP::Lite
SOAP::WSDL does not aim to be a complete replacement for SOAP::Lite - the SOAP::Lite module has its
strengths and weaknesses and SOAP::WSDL is designed as a cure for the weakness of little WSDL support -
nothing more, nothing less.
Nonetheless SOAP::WSDL mimics part of SOAP::Lite's API and behaviour, so SOAP::Lite users can switch
without looking up every method call in the documentation.
A few things are quite different from SOAP::Lite, though:
SOAPrequestdata
SOAP request data may either be given as message object, or as a hash ref (in which case it will
automatically be encoded into a message object).
Returnvalues
The result from call() is not a SOAP::SOM object, but a message object.
Message objects' classes may be generated from WSDL definitions automatically - see
SOAP::WSDL::Generator::Typelib on how to generate your own WSDL based message class library.
Faulthandling
SOAP::WSDL::Client returns a fault object on errors, even on transport layer errors.
The fault object is a SOAP1.1 fault object of the following "SOAP::WSDL::SOAP::Typelib::Fault11".
SOAP::WSDL::SOAP::Typelib::Fault11 objects are false in boolean context, so you can just do something
like:
my $result = $soap->call($method, $data);
if ($result) {
# handle result
}
else {
die $result->faultstring();
}
outputxml
SOAP::Lite returns only the content of the SOAP body when outputxml is set to true. SOAP::WSDL::Client
returns the complete XML response.
Auto-Dispatching
SOAP::WSDL::Client doesnot 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.
