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 $/; <STDIN> };
length($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 <http://rt.cpan.org> to report and view bugs.
