Catalyst::Action::Serialize - Serialize Data in a Response

    package Foo::Controller::Bar;

    __PACKAGE__->config(
        'default'   => 'text/x-yaml',
        'stash_key' => 'rest',
        'map'       => {
            'text/html'          => [ 'View', 'TT', ],
            'text/x-yaml'        => 'YAML',
            'text/x-data-dumper' => [ 'Data::Serializer', 'Data::Dumper' ],
        }
    );

    sub end :ActionClass('Serialize') {}

This action will serialize the body of an HTTP Response. The serializer is selected by introspecting the HTTP Requests content-type header.

It requires that your Catalyst controller is properly configured to set up the mapping between Content Type's and Serialization classes.

The specifics of serializing each content-type is implemented as a plugin to Catalyst::Action::Serialize.

Typically, you would use this ActionClass on your end method. However, nothing is stopping you from choosing specific methods to Serialize:

  sub foo :Local :ActionClass('Serialize') {
     .. populate stash with data ..
  }

When you use this module, the request class will be changed to Catalyst::Request::REST.

Takes a hashref, mapping Content-Types to a given serializer plugin.

This is the 'fall-back' Content-Type if none of the requested or acceptable types is found in the map. It must be an entry in the map.

Specifies the key of the stash entry holding the data that is to be serialized. So if the value is "rest", we will serialize the data under:

  $c->stash->{'rest'}

Specifies the key of the stash entry that optionally holds an overriding Content-Type. If set, and if the specified stash entry has a valid value, then it takes priority over the requested content types.

This can be useful if you want to dynamically force a particular content type, perhaps for debugging.

Daisuke Maki pointed out that early versions of this Action did not play well with others, or generally behave in a way that was very consistent with the rest of Catalyst.

You likely want to look at Catalyst::Controller::REST, which implements a sensible set of defaults for doing a REST controller.
