NAME
CatalystX::Controller::PSGI - use a PSGI app in a Catalyst Controller
SYNOPSIS
package TestApp::Controller::File;
use Moose;
use namespace::autoclean;
BEGIN { extends 'CatalystX::Controller::PSGI'; }
use Plack::App::File;
use Plack::Response;
has 'app_file' => (
is => 'ro',
default => sub {
return Plack::App::File->new(
file => __FILE__,
content_type => 'text/plain',
)->to_app;
},
);
sub call {
my ( $self, $env ) = @_;
$self->app_file->( $env );
}
my $hello_app = sub {
my ( $self, $env ) = @_;
my $res = Plack::Response->new(200);
$res->content_type('text/plain');
$res->body("hello world");
return $res->finalize;
};
__PACKAGE__->mount( '/hello/world' => $hello_app );
__PACKAGE__->meta->make_immutable;
DESCRIPTION
Use PSGI apps inside Catalyst Controllers.
Combine this with Catalyst::Component::InstancePerContext if you want to access $c in your psgi app
Usage
call method
If this method is provided, it will be called as the root action of that controller.
package TestApp::Controller::File;
use Moose;
use namespace::autoclean;
BEGIN { extends 'CatalystX::Controller::PSGI'; }
use Plack::App::File;
has 'app_file' => (
is => 'ro',
default => sub {
return Plack::App::File->new(
file => __FILE__,
content_type => 'text/plain',
)->to_app;
},
);
sub call {
my ( $self, $env ) = @_;
$self->app_file->( $env );
}
__PACKAGE__->meta->make_immutable;
E.g. in the above example it will be /file/
Works similar to Plack::Component, except that as well as $env being passed in, $self is as well. Where $env is the psgi env, and $self is the Catalyst Controller.
mount
Mount a path within the controller to an app.
package TestApp::Controller::Hello;
use Moose;
use namespace::autoclean;
BEGIN { extends 'CatalystX::Controller::PSGI'; }
use Plack::Response;
my $hello_app = sub {
my ( $self, $env ) = @_;
my $res = Plack::Response->new(200);
$res->content_type('text/plain');
$res->body("hello world");
return $res->finalize;
};
__PACKAGE__->mount( '/world' => $hello_app );
__PACKAGE__->meta->make_immutable;
In the above example the url /hello/world will be bound to the $hello_app. As with call, $self and $env will be passed in.
