Dancer::Serializer::Mutable - Serialize and deserialize content using the appropriate HTTP header
version 1.3300
# in config.yml serializer: Mutable # in the app put '/something' => sub { # deserialized from request my $name = param( 'name' ); ... # will be serialized to the most # fitting format return { message => "user $name added" }; };
This serializer will try find the best (de)serializer for a given request. For this, it will pick the first content type found from the following list and use its related serializer.
The content_type from the request headers
the content_type parameter from the URL
the accept from the request headers
The default is application/json
The content-type/serializer mapping that Dancer::Serializer::Mutable uses is
Dancer::Serializer::Mutable
serializer | content types ---------------------------------------------------------- Dancer::Serializer::YAML | text/x-yaml, text/html Dancer::Serializer::XML | text/xml Dancer::Serializer::JSON | text/x-json, application/json
For instances where you want to render a template for normal browser requests, and return serialized content for AJAX calls.
If the requested content-type is text/html, template_or_serialize returns the rendered template, else it returns $data unmodified (which will then be serialized as usual).
template_or_serialize
template_or_serialize is not exported by default.
use Dancer::Serializer::Mutable qw/ template_or_serialize /; get '/greetings' => sub { ...; return template_or_serialize 'greetings' => { title => $title, name => $name, }; };
The following methods are used internally by Dancer and are not made accessible via the DSL.
Dancer
Serialize a data structure. The format it is serialized to is determined automatically as described above. It can be one of YAML, XML, JSON, defaulting to JSON if there's no clear preference from the request.
Deserialize the provided serialized data to a data structure. The type of serialization format depends on the request's content-type. For now, it can be one of YAML, XML, JSON.
Returns the content-type that was used during the last serialize / deserialize call. WARNING : you must call serialize / deserialize before calling content_type. Otherwise the return value will be undef.
