Catalyst::Plugin::SmartURI(3) Configurable URIs for Catalyst

SYNOPSIS

In your lib/MyApp.pm, load the plugin and your other plugins, for example:


use Catalyst qw/
-Debug
ConfigLoader
Static::Simple
Session
Session::Store::Memcached
Session::State::Cookie
Authentication
Authorization::Roles
+CatalystX::SimpleLogin
SmartURI
/;

In your .conf:

    <Plugin::SmartURI>
        disposition host-header   # application-wide
        uri_class   URI::SmartURI # by default
    </Plugin::SmartURI>

Per request:

    $c->uri_disposition('absolute');

Methods on URIs:

    <a href="[% c.uri_for('/foo').relative %]" ...

DESCRIPTION

Configure whether "$c->uri_for" and "$c->req->uri_with" return absolute, hostless or relative URIs, or URIs based on the 'Host' header. Also allows configuring which URI class to use. Works on application-wide or per-request basis.

This is useful in situations where you're for example, redirecting to a lighttpd from a firewall rule, instead of a real proxy, and you want your links and redirects to still work correctly.

To use your own URI class, just subclass URI::SmartURI and set "uri_class", or write a class that follows the same interface.

This plugin installs a custom "$c->request_class", however it does so in a way that won't break if you've already set "$c->request_class" yourself, ie. by using Catalyst::Action::REST (thanks mst!).

There is a minor performance penalty in perls older than 5.10, due to Class::C3, but only at initialization time.

METHODS

$c->uri_for

$c->req->uri_with

Returns a "$c->uri_class" object (URI::SmartURI by default) in the configured "$c->uri_disposition".

$c->req->uri

Returns a "$c->uri_class" object. If the context hasn't been prepared yet, uses the configured value for "uri_class".

"$c->req->uri->relative" will be relative to "$c->req->base".

$c->req->referer

Returns a "$c->uri_class" object for the referer (or configured "uri_class" if there's no context) with reference set to "$c->req->uri" if it comes from "$c->req->base".

In other words, if referer is your app, you can do "$c->req->referer->relative" and it will do the right thing.

CONFIGURATION

In myapp.conf:

    <Plugin::SmartURI>
        disposition absolute
        uri_class   URI::SmartURI
    </Plugin::SmartURI>
disposition
One of 'absolute', 'hostless', 'relative' or 'host-header'. Defaults to 'absolute'.

The special disposition 'host-header' uses the value of your 'Host:' header.

uri_class
The class to use for URIs, defaults to URI::SmartURI.

PER REQUEST

    package MyAPP::Controller::RSSFeed;
    ...
    sub begin : Private {
        my ($self, $c) = @_;
        $c->uri_class('Your::URI::Class::For::Request');
        $c->uri_disposition('absolute');
    }
$c->uri_disposition('absolute'|'hostless'|'relative'|'host-header')
Set URI disposition to use for the duration of the request.
$c->uri_class($class)
Set the URI class to use for "$c->uri_for" and "$c->req->uri_with" for the duration of the request.

EXTENDING

"$c->prepare_uri" actually creates the URI, which you can override.

I'd like to extend on Catalyst::Plugin::RequireSSL, and make a plugin that rewrites URIs for actions with an SSL attribute.
