NAME

Prancer::Context

SYNOPSIS

The context gives you access to all pieces of a request from request parameters to cookies, sessions and headers. It can be used by calling context from anywhere in a package that extends Prancer::Application. Otherwise you must pass it to other packages to make it available.

    use Prancer::Application qw(:all);
    use parent qw(Prancer::Application);

    sub handle {
        my ($self, $env) = @_;

        mount('GET', '/', sub {
            context->header(set => 'Content-Type', value => 'text/plain');
            context->body("hello world");
            context->finalize(200);
        });

        return dispatch;
    }

METHODS

env

Returns the PSGI environment for the request.

template

This is a magical wrapper to Prancer::template() in that it works by calling Prancer::template but it will merge params, config, and session into the list of template variables using their respective names as the first key. This allows you to write this in your template:

    <% params.bar %>
    <% config.foo.bar %>
    <% session.asdf.fdsa %>

session

This gives access to the session in various ways. For example:

    my $does_foo_exist = context->session->has('foo');
    my $foo = context->session->get('foo');
    context->session->set('foo', 'bar');
    context->session->remove('foo');

Changes made to the session are persisted immediately to whatever medium backs your sessions.

request

Returns the Prancer::Request object for the request.

response

Returns the Prancer::Response object that will be used to generate the response.

header

This gives access request and response headers. For example:

    # get a request header
    my $useragent = context->header(get => 'user-agent');

    # set a response header
    context->header(set => 'Content-Type', value => 'text/plain');

cookie

This gives access to request and response cookies. For example:

    # get a request cookie
    my $foo = context->cookie(get => 'foo');

    # set a response cookie
    context->cookie(set => 'foo', value => {
        'value' => 'bar',
        'domain' => '.example.com',
    });

uploads
