NAME

Dancer2::Serializer::Mutable - Serialize and deserialize content based on HTTP header

CONTENTS

VERSION

version 0.166001

SYNOPSIS



    # 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" };
    };



DESCRIPTION

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.
o The <B>content_typeB> from the request headers
o the <B>acceptB> from the request headers
o The default is <B>application/jsonB>
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

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

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.

    content_type

Returns the content-type that was used during the last serialize / deserialize call. <B>WARNINGB> : you must call serialize / deserialize before calling content_type. Otherwise the return value will be undef.
