Plack::App::Path::Router - A Plack component for dispatching with Path::Router
VERSION
version 0.08
SYNOPSIS
use Plack::App::Path::Router;
use Path::Router;
my $router = Path::Router->new;
$router->add_route('/' =>
target => sub {
my ($request) = @_;
# use the Plack::Request to
# create a Plack::Response ...
my $response = $request->new_response( 200 );
$response->content_type('text/html');
$response->body('<html><body>HELLO WORLD</body></html>');
}
);
$router->add_route('/:action/?:id' =>
validations => {
id => 'Int'
},
target => sub {
# matches are passed to the target sub ...
my ($request, $action, $id) = @_;
# return a PSGI response ...
[
200,
[ 'Content-Type' => 'text/html' ],
[ '<html><body>', $action, $id, '</body></html>' ]
]
}
);
$router->add_route('/:action/edit/:id' =>
validations => {
id => 'Int'
},
target => sub {
my ($r, $action, $id) = @_;
# return a string (we will wrap
# it in a PSGI response for you)
"This is my action($action), and I am editing this id($id)";
}
);
$router->add_route('/foo' =>
# target objects are also supported
# as long as the object responds to
# the ->execute method
target => MyApp::Action->new( type => 'FOO' )
);
# now create the Plack app
my $app = Plack::App::Path::Router->new( router => $router );
DESCRIPTION
This is a Plack::Component subclass which creates an endpoint to dispatch using Path::Router.
This module expects an instance of Path::Router whose routes all have a target
that is a CODE ref or an object which responds to the execute
method. The CODE ref or execute
method will be called when a match is found and passed a Plack::Request instance followed by any path captures that were found. It is expected that the target return one of the following; an object which responds to the finalize
method (like Plack::Response), a properly formed PSGI response or a plain string (which we will wrap inside a PSGI response with a status of 200 and a content type of "text/html").
This thing is dead simple, if my docs don't make sense, then just read the source (all ~75 lines of it).
ATTRIBUTES
router
This is a required attribute and must be an instance of Path::Router.
request_class
This is a class name used to create the request object. It defaults to Plack::Request but anything that will accept a PSGI-style $env
in the constructor and respond correctly to path_info
will work.
