NAME
XML::RPC::Fast - Fast and modular implementation for an XML-RPC client
and server

SYNOPSIS
Generic usage

use XML::RPC::Fast;

my $server = XML::RPC::Fast->new( undef, %args );
my $client = XML::RPC::Fast->new( $uri, %args );

Create a simple XML-RPC service:

use XML::RPC::Fast;

my $rpc = XML::RPC::Fast->new(
undef, # the url is not required by server
external_encoding => 'koi8-r', # any encoding, accepted by Encode
#internal_encoding => 'koi8-r', # not supported for now
);
my $xml = do { local $/; };
length($xml) == $ENV{CONTENT_LENGTH} or warn "Content-Length differs from actually received";

print "Content-type: text/xml; charset=$rpc->{external_encoding}\n\n";
print $rpc->receive( $xml, sub {
my ( $methodname, @params ) = @_;
return { you_called => $methodname, with_params => \@params };
} );

Make a call to an XML-RPC service:

use XML::RPC::Fast;

my $rpc = XML::RPC::Fast->new(
'http://your.hostname/rpc/url'
);

# Syncronous call
my @result = $rpc->req(
call => [ 'examples.getStateStruct', { state1 => 12, state2 => 28 } ],
url => 'http://...',
);

# Syncronous call (compatibility method)
my @result = $rpc->call( 'examples.getStateStruct', { state1 => 12, state2 => 28 } );

# Syncronous or asyncronous call
$rpc->req(
call => ['examples.getStateStruct', { state1 => 12, state2 => 28 }],
cb => sub {
my @result = @_;
},
);

# Syncronous or asyncronous call (compatibility method)
$rpc->call( sub {
my @result = @_;

}, 'examples.getStateStruct', { state1 => 12, state2 => 28 } );

DESCRIPTION
XML::RPC::Fast is format-compatible with XML::RPC, but may use different
encoders to parse/compose xml. Curerntly included encoder uses
XML::LibXML, and is 3 times faster than XML::RPC and 75% faster, than
XML::Parser implementation

METHODS
new ($url, %args)
Create XML::RPC::Fast object, server if url is undef, client if url is
defined

req( %ARGS )
Clientside. Make syncronous or asyncronous call (depends on UA).

If have cb, will invoke $cb with results and should not croak

If have no cb, will return results and croak on error (only syncronous
UA)

Arguments are

call => [ methodName => @args ]
array ref of call arguments. Required

cb => $cb->(@results)
Invocation callback. Optional for syncronous UA. Behaviour is same
as in call with $cb and without

url => $request_url
Alternative invocation URL. Optional. By default will be used
defined from constructor

headers => { http-headers hashref }
Additional http headers to request

external_encoding => '...,
Specify the encoding, used inside XML container just for this
request. Passed to encoder

call( 'method_name', @arguments ) : @results
Clientside. Make syncronous call and return results. Croaks on error.
Just a simple wrapper around "req"

call( $cb->(@res), 'method_name', @arguments ): void
Clientside. Make syncronous or asyncronous call (depends on UA) and
invoke $cb with results. Should not croak. Just a simple wrapper around
"req"

receive ( $xml, $handler->($methodName,@args) ) : xml byte-stream
Serverside. Process received XML and invoke $handler with parameters
$methodName and @args and returns response XML

On error conditions $handler could set $XML::RPC::Fast::faultCode and
die, or return "rpcfault($faultCode,$faultString)"

->receive( $xml, sub {
# ...
return rpcfault( 3, "Some error" ) if $error_condition
$XML::RPC::Fast::faultCode = 4 and die "Another error" if $another_error_condition;

return { call => $methodname, params => \@params };
})

registerType
Proxy-method to encoder. See XML::RPC::Enc

registerClass
Proxy-method to encoder. See XML::RPC::Enc

OPTIONS
Below is the options, accepted by new()

ua
Client only. Useragent object, or package name

->new( $url, ua => 'LWP' ) # same as XML::RPC::UA::LWP
# or
->new( $url, ua => 'XML::RPC::UA::LWP' )
# or
->new( $url, ua => XML::RPC::UA::LWP->new( ... ) )
# or
->new( $url, ua => XML::RPC::UA::Curl->new( ... ) )

timeout
Client only. Timeout for calls. Passed directly to UA

->new( $url, ua => 'LWP', timeout => 10 )

useragent
Client only. Useragent string. Passed directly to UA

->new( $url, ua => 'LWP', useragent => 'YourClient/1.11' )

encoder
Client and server. Encoder object or package name

->new( $url, encoder => 'LibXML' )
# or
->new( $url, encoder => 'XML::RPC::Enc::LibXML' )
# or
->new( $url, encoder => XML::RPC::Enc::LibXML->new( ... ) )

internal_encoding NOT IMPLEMENTED YET
Specify the encoding you are using in your code. By default option is
undef, which means flagged utf-8 For translations is used Encode, so the
list of accepted encodings fully derived from it.

external_encoding
Specify the encoding, used inside XML container. By default it's utf-8.
Passed directly to encoder

->new( $url, encoder => 'LibXML', external_encoding => 'koi8-r' )

ACCESSORS
url
Get or set client url

encoder
Direct access to encoder object

ua
Direct access to useragent object

FUNCTIONS
rpcfault(faultCode, faultString)
Returns hash structure, that may be returned by serverside handler,
instead of die. Not exported by default

CUSTOM TYPES
sub {{ 'base64' => encode_base64($data) }}
When passing a CODEREF as a value, encoder will simply use the returned
hashref as a type => value pair.

bless( do{\(my $o = encode_base64('test') )}, 'base64' )
When passing SCALARREF as a value, package name will be taken as type
and dereference as a value

bless( do{\(my $o = { something =>'complex' } )}, 'base64' )
When passing REFREF as a value, package name will be taken as type and
XML::Hash::LX"::hash2xml(deref)" would be used as value

customtype( $type, $data )
Easily compose SCALARREF based custom type

BUGS & SUPPORT
Bugs reports and testcases are welcome.

It you write your own Enc or UA, I may include it into distribution

If you have propositions for default custom types (see Enc), send me
patches

See to report and view bugs.
