Outputting data other than HTML¶

JSON¶

Amon2::Plugin::Web::JSON supports output in JSON format. You can load it as:

__PACKAGE__->load_plugin(qw/JSON/);

And use it as follows:

sub dispatch {
    my $c = shift;

    my $response = $c->render_json({'data' => 'OK'});
    return $response;
}

If you want to use JSONP, you would use Plack::Middleware::JSONP.

CSV¶

Amon2 does not support CSV, but you can output CSV data using Text::CSV:

sub dispatch {
    my $c = shift;

    my $csv = Text::CSV->new ( { binary => 1 } )
        or die "Cannot use CSV: ".Text::CSV->error_diag ();

    my $output = join("\n",
        $csv->combine(qw/Foo Bar Baz/),
        $csv->combine(qw/1 2 3/),
    );

    return $c->create_response(
        200,
        [
            'Content-Disposition' => 'attachment; filename=somefilename.csv',
            'Content-Type' => 'text/csv; charset=utf-8',
        ],
        [$output]
    );
}
