"The HTTP POST, PUT, and OPTIONS methods will all automatically

-C<< $c->request->body >> into the C<< $c->request->data >> hashref", based on
+C<< $c->request->body >> into the C<< $c->request->data >> hashref", based on
the request's C<Content-type> header. A list of understood serialization
formats is L<below|/AVAILABLE SERIALIZERS>.
L<JSON::XS> installed. The C<text/x-json> content type is supported but is
deprecated and you will receive warnings in your log.
+You can also add a hash in your controller config to pass options to the json object.
+For instance, to relax permissions when deserializing input, add:
+ __PACKAGE__->config(
+ json_options => { relaxed => 1 }
+ )
+
=item * C<text/javascript> => C<JSONP>
If a callback=? parameter is passed, this returns javascript in the form of: $callback($serializedJSON);
$c->response->body( $output );
return 1; # important
}
-
+
sub serialize {
my ( $self, $data ) = @_;
return $serialized;
}
+=item * Callback
+
+For infinite flexibility, you can provide a callback for the
+deserialization/serialization steps.
+
+ __PACKAGE__->config(
+ map => {
+ 'text/xml' => [ 'Callback', { deserialize => \&parse_xml, serialize => \&render_xml } ],
+ }
+ );
+
+The C<deserialize> callback is passed a string that is the body of the
+request and is expected to return a scalar value that results from
+the deserialization. The C<serialize> callback is passed the data
+structure that needs to be serialized and must return a string suitable
+for returning in the HTTP response. In addition to receiving the scalar
+to act on, both callbacks are passed the controller object and the context
+(i.e. C<$c>) as the second and third arguments.

Returns a "202 ACCEPTED" response. Takes an "entity" to serialize.
+Also takes optional "location" for queue type scenarios.
Example:

}

+=item status_forbidden

+Returns a "403 FORBIDDEN" response. Takes a "message" argument

Returns a "404 NOT FOUND" response. Takes a "message" argument
The C<begin> method uses L<Catalyst::Action::Deserialize>. The C<end>
method uses L<Catalyst::Action::Serialize>. If you want to override
either behavior, simply implement your own C<begin> and C<end> actions
-and use MRO::Compat:
+and forward to another action with the Serialize and/or Deserialize
+action classes:
