Catalyst::TraitFor::Request::REST - A role to apply to Catalyst::Request giving it REST methods and attributes.


     if ( $c->request->accepts('application/json') ) {

     my $types = $c->request->accepted_content_types();


This is a Moose::Role applied to Catalyst::Request that adds a few methods to the request object to facilitate writing REST-y code. Currently, these methods are all related to the content types accepted by the client and the content type sent in the request.



If the request went through the Deserializer action, this method will return the deserialized data structure.


Returns an array reference of content types accepted by the client.

The list of types is created by looking at the following sources:

  • Content-type header

    If this exists, this will always be the first type in the list.

  • content-type parameter

    If the request is a GET request and there is a "content-type" parameter in the query string, this will come before any types in the Accept header.

  • Accept header

    This will be parsed and the types found will be ordered by the relative quality specified for each type.

If a type appears in more than one of these places, it is ordered based on where it is first found.


This returns the first content type found. It is shorthand for:


Given a content type, this returns true if the type is accepted.

Note that this does not do any wildcard expansion of types.
