=head1 NAME

AMF::Connection - A simple library to write AMF clients.

=head1 SYNOPSIS

  use AMF::Connection;

  my $endpoint = 'http://myserver.com/flex/amf/'; #AMF server/gateway

  my $service = 'myService';
  my $method = 'myMethod';

  my $client = new AMF::Connection( $endpoint );

  $client->setEncoding(3); # use AMF3 default AMF0

  $client->setHTTPCookieJar( HTTP::Cookies->new(file => "/tmp/mycookies.txt", autosave => 1, ignore_discard => 1 ) );

  my @params = ( 'param1', { 'param2' => 'value2' } );
  my $response = $client->call( "$service.$method", \@params );

  if ( $response->is_success ) {
        my $result_object = $response->getData();
	# ...
  } else {
        die "Can not send remote request for $service.$method method on $endpoint\n";
        };

  my @response = $client->callBatch ( { "operation" => $service.$method", "arguments" => \@params }, ... );

=head1 DESCRIPTION

I was looking for a simple Perl module to automate data extraction from an existing Flash+Flex/AMS application, and I could not find a decent client implementation. So, this module was born based on available online documentation.

This module has been inspired to SabreAMF PHP implementation of AMF client libraries.

AMF::Connection is meant to provide a simple AMF library to write client applications for invocation of remote services as used by most flex/AIR RIAs. 

The module includes basic support for synchronous HTTP/S based RPC request-response access, where the client sends a request to the server to be processed and the server returns a response to the client containing the processing outcome. Data is sent...

AMF0 and AMF3 support is provided using the Storable::AMF module. While HTTP/S requestes to the AMF endpoint are carried out using the LWP::UserAgent module. The requests are sent using the HTTP POST method as AMF0 encoded data by default. AMF3 encod...

If encoding is set to AMF3 the Flex Messaging framework is used on returned responses content (I.e. objects casted to "flex.messaging.messages.AcknowledgeMessage" and "flex.messaging.messages.ErrorMessage" are returned).

Simple batch requests and responses is provided also.

See the sample usage synopsis above to start using the module.

=head1 DATE TYPE SUPPORT

The latest 0.79 version of Storable::AMF added basic date support with the new_date() and perl_date() utilitiy functions. This is just great. Internally an AMF Date Type represents a timestamp in milliseconds since the epoch in UTC ("neutral") timezo...

#....

For other Java to ActionScript type mappings possibilities see http://livedocs.adobe.com/blazeds/1/javadoc/flex/messaging/io/amf/ActionMessageOutput.html#writeObject(java.lang.Object)

For PHP gateways at the moment there is not a known/documented way to map client to server objects.

Future versions of AMF::Connection may add a proper configurable factory for application specific ActionScript/Flex object mappings.

=head1 METHODS

=head2 new ($endpoint)

Create new AMF::Connection object. An endpoint can be specified as the only parameter. Or set in a second moment with the setEndpoint() method.

=head2 call ($operation, $arguments)

Call the remote service method with given parameters/arguments on the set endpoint and return an AMF::Connection::MessageBody response. Or an array of responses if requsted (wantarray call scope). The $arguments is generally an array reference, but t...

=head2 callBatch (@batch)

Call the remote service once in batch. Each element of @batch must be an hash like { "operation" => $operation, "arguments" => $arguments }, where $operation and $arguments are as specified in C<call>. The commands are called and responses returned i...

=head2 setEndpoint ($endpoint)

Set the AMF service endpoint.

=head2 getEndpoint ()

Return the AMF service endpoint.

=head2 setEncoding ($encoding)

Set the AMF encoding to use.

=head2 getEncoding ()

Return the AMF encoding in use.

=head2 setHTTPProxy ($proxy)
