Dancer2::Core::Role::Headers - Role for handling headers
version 0.159002
When a class consumes this role, it gets a headers attribute and all the helper methods to manipulate it.
headers
This logic is contained in this role in order to reuse the code between Dancer2::Core::Response and Dancer2::Core::Request objects.
The attribute that store the headers in a HTTP::Headers object.
That attribute coerces from ArrayRef and defaults to an empty HTTP::Headers instance.
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.
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 );
Convert the headers attribute to an ArrayRef.
