.TH Catalyst::Request::REST 3 "2007-07-07" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Catalyst::Request::REST \- A REST\-y subclass of Catalyst::Request

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a subclass of \f(CW\*(C`Catalyst::Request\*(C'\fR that adds a few methods to
the request object to faciliate writing REST-y code. Currently, these
methods are all related to the content types accepted by the client.
.SH "METHODS"
.IX Header "METHODS"
.RS 4
If the request went through the Deserializer action, this method will
returned the deserialized data structure.
.RE
.IP "accepted_content_types" 4
.IX Item "accepted_content_types"
Returns an array reference of content types accepted by the
client.
.Sp
The list of types is created by looking at the following sources:
.RS 4
.IP "* Content-type header" 8
.IX Item "Content-type header"
If this exists, this will always be the first type in the list.
.IP "* content-type parameter" 8
.IX Item "content-type parameter"
If the request is a \s-1GET\s0 request and there is a \*(L"content\-type\*(R"
parameter in the query string, this will come before any types in the
Accept header.
.IP "* Accept header" 8
.IX Item "Accept header"
This will be parsed and the types found will be ordered by the
relative quality specified for each type.
.RE
.RS 4
.Sp
If a type appears in more than one of these places, it is ordered based on
where it is first found.
.RE
.IP "preferred_content_type" 4
.IX Item "preferred_content_type"
This returns the first content type found. It is shorthand for:
.Sp
.Vb 1
\&  $request->accepted_content_types->[0]
.Ve
.IP "accepts($type)" 4
.IX Item "accepts($type)"
Given a content type, this returns true if the type is accepted.
.Sp
Note that this does not do any wildcard expansion of types.
