NAME
SOAP::WSDL::Factory::Transport - Factory for retrieving transport objects
SYNOPSIS
# from SOAP::WSDL::Client:
$transport = SOAP::WSDL::Factory::Transport->get_transport( $url, @opt );
# in transport class:
package MyWickedTransport;
use SOAP::WSDL::Factory::Transport;
# register class as transport module for httpr and https
# (httpr is "reliable http", a protocol developed by IBM).
SOAP::WSDL::Factory::Transport->register( 'httpr' , __PACKAGE__ );
SOAP::WSDL::Factory::Transport->register( 'https' , __PACKAGE__ );DESCRIPTION
SOAP::WSDL::Transport serves as factory for retrieving transport objects for SOAP::WSDL.
The actual work is done by specific transport classes.
SOAP::WSDL::Transport tries to load one of the following classes:
the class registered for the scheme via register()
the SOAP::Lite class matching the scheme
the SOAP::WSDL class matching the scheme
METHODS
register
SOAP::WSDL::Transport->register('https', 'MyWickedTransport');Globally registers a class for use as transport class.
proxy
$trans->proxy('http://soap-wsdl.sourceforge.net');Sets the proxy (endpoint).
Returns the transport for this protocol.
set_transport
Sets the current transport object.
get_transport
Gets the current transport object.
WRITING YOUR OWN TRANSPORT CLASS
Registering a transport class
Transport classes must be registered with SOAP::WSDL::Factory::Transport.
This is done by executing the following code where $scheme is the URL scheme the class should be used for, and $module is the class' module name.
SOAP::WSDL::Factory::Transport->register( $scheme, $module);To auto-register your transport class on loading, execute register() in your tranport class (see SYNOPSIS above).
Multiple protocols or multiple classes are registered by multiple calls to register().
Transport plugin package layout
You may only use transport classes whose name is either the module name or the module name with '::Client' appended.
Methods to implement
Transport classes must implement the interface required for SOAP::Lite transport classes (see SOAP::Lite::Transport for details, SOAP::WSDL::Transport::HTTP for an example).
To provide this interface, transport modules must implement the following methods:
new
send_receive
Dispatches a request and returns the content of the response.
code
Returns the status code of the last send_receive call (if any).
message
Returns the status message of the last send_receive call (if any).
status
Returns the status of the last send_receive call (if any).
is_success
Returns true after a send_receive was successful, false if it was not.
SOAP::Lite requires transport modules to pack client and server classes in one file, and to follow this naming scheme:
Module name:
"SOAP::Transport::" . uc($scheme)
Client class (additional package in module):
"SOAP::Transport::" . uc($scheme) . "::Client"
Server class (additional package in module):
"SOAP::Transport::" . uc($scheme) . "::Client"SOAP::WSDL does not require you to follow these restrictions.
There is only one restriction in SOAP::WSDL:
You may only use transport classes whose name is either the module name or the module name with '::Client' appended.
SOAP::WSDL will try to instantiate an object of your transport class with '::Client' appended to allow using transport classes written for SOAP::Lite.
This may lead to errors when a different module with the name of your transport module suffixed with ::Client is also loaded.
