NAME

Dancer2::Core::Role::Headers - Role for handling headers

VERSION

version 0.10

DESCRIPTION

When a class consumes this role, it gets a headers attribute and all the helper methods to manipulate it.

This logic is contained in this role in order to reuse the code between Dancer2::Core::Response and Dancer2::Core::Request objects.

ATTRIBUTES

headers

The attribute that store the headers in a HTTP::Headers object.

That attribute coerces from ArrayRef and defaults to an empty HTTP::Headers instance.

METHODS

header($name)

Return the value of the given header, if present. If the header has multiple values, returns the list of values if called in list context, the first one if in scalar context.

push_header

Add the header no matter if it already exists or not.

$self->push_header( 'X-Wing' => '1' );

It can also be called with multiple values to add many times the same header with different values:

$self->push_header( 'X-Wing' => 1, 2, 3 );

headers_to_array

Convert the headers attribute to an ArrayRef.
