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

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('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

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

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"

does not require you to follow these restrictions.

There is only one restriction in

You may only use transport classes whose name is either the module name or the module name with '::Client' appended.

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.
