NAME¶
Dancer2::Core::Role::Headers - Role for handling headers
VERSION¶
version 0.152000
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¶
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¶
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.
