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.
