Dancer2::Serializer::Mutable

Serialize and deserialize content based on HTTP header

version 0.166001

    # 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 valid content type found from the following list and use its related serializer.

  • The content_type from the request headers
  • the accept from the request headers
  • The default is application/json

The content-type/serializer mapping that "Dancer2::Serializer::Mutable" uses is

    serializer                  | content types
    ----------------------------------------------------------
    Dancer2::Serializer::YAML   | text/x-yaml, text/html
    Dancer2::Serializer::Dumper | text/x-data-dumper
    Dancer2::Serializer::JSON   | text/x-json, application/json

INTERNAL METHODS

The following methods are used internally by "Dancer2" and are not made accessible via the DSL.

Serialize a data structure. The format it is serialized to is determined automatically as described above. It can be one of YAML, Dumper, 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, Dumper, 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".
