NAME

WWW::REST - Base class for REST resources

VERSION

This document describes version 0.01 of WWW::REST, released October 21, 2003.

SYNOPSIS

    use XML::RSS;
    use WWW::REST;
    $url = WWW::REST->new("http://nntp.x.perl.org/rss/perl.par.rdf");
    $url->dispatch( sub {
        my $self = shift;
        die $self->status_line if $self->is_error;
        my $rss = XML::RSS->new;
        $rss->parse($self->content);
        return $rss;
    });
    $url->get( last_n => 10 )->save("par.rdf");
    $url->url("perl.perl5.porters.rdf")->get->save("p5p.rdf");
    warn $url->dir->as_string;    # "http://nntp.x.perl.org/rss/"
    warn $url->parent->as_string; # "http://nntp.x.perl.org/"
    $url->delete;                 # dies with "405 Method Not Allowed"

DESCRIPTION

This module is a mixin of URI, LWP::UserAgent, HTTP::Response and an user-defined dispatch module. It is currently just a proof of concept for a resource-oriented API framework, also known as REST (Representational State Transfer).

METHODS

WWW::REST->new($string, @args)

Constructor (class method). Takes an URL string, returns a WWW::REST object. The optional arguments are passed to LWP::UserAgent->new.

$url->url($string)

Constructor (instance method). Takes an URL string, which may be relative to the object's URL. Returns a WWW::REST object, which inherits the same ua and dispatcher.

$url->dispatch($coderef)

Gets or sets the dispatch code reference.

$url->_uri($uri), $url->_ua($uri), $url->_res($uri)

Gets or sets the embedded URI, LWP::UserAgent and HTTP::Response objects respectively. Note that $url can automatically delegate method calls to embedded objects, so normally you won't need to call those method explicitly.

$url->get(%args), $url->post(%args), $url->head(%args), $url->put(%args), $url->delete(%args), $url->options(%args), $url->trace(%args), $url->connect(%args)

Performs the corresponding operation to the object; returns the object itself. If dispatch is set to a code reference, the object is passed to it instead, and returns its return value.

$url->parent()

Returns a WWW::REST object with the URL of the current object's parent directory.

$url->dir()

Returns a WWW::REST object with the URL of the current object's current directory.

NOTES

This module is considered highly experimental. The API may change without notice; suggestions are most welcome.

The documentation you are reading really needs a rewrite. :-)
