Dancer::Serializer::JSON - serializer for handling JSON data
SYNOPSIS DESCRIPTION
This class is an interface between Dancer's serializer engine abstraction layer and the JSON module.
In order to use this engine, use the template setting:
serializer: JSON
This can be done in your config.yml file or directly in your app code with the set keyword. This serializer will also be used when the
serializer is set to mutable and the correct Accept headers are supplied.
The JSON module will pass configuration variables straight through. Some of these can be useful when debugging/developing your app: pretty
and canonical, and others useful with ORMs like DBIx::Class: allow_blessed and convert_blessed. Please consult the JSON documentation for
more information and a full list of configuration settings. You can add extra settings to the engines configuration to turn these on. For
example:
engines:
JSON:
allow_blessed: '1'
canonical: '1'
convert_blessed: '1'
METHODS
serialize
Serialize a data structure to a JSON structure.
deserialize
Deserialize a JSON structure to a data structure
content_type
Return 'application/json'

Dancer::Serializer - serializer wrapper for Dancer
DESCRIPTION
This module is the wrapper that provides support for different serializers.
USAGE
Configuration
The serializer configuration variable tells Dancer which serializer to use to deserialize request and serialize response.
You change it either in your config.yml file:
serializer: "YAML"
Or in the application code:
# setting JSON as the default serializer
set serializer => 'JSON';
In your routes you can access parameters just like any route.
When in a route you return a Perl data structure, it will be serialized automatically to the respective serialized engine (for instance,
"JSON").
For "PUT" and "POST" methods you can access the "request-"body> as a string, and you can unserialize it, if you really need. If your
content type is recognized by the serializer, "request-"body> will be unserialized automatically, and it will be available as a standard
parameter.
For instance, if you call
curl -X POST -H 'Content-Type: application/json -d "{'id':'bar'}" /foo
your "foo" route can do something like:
post "/foo" => {
my $id = param('id'); # gets "bar"
# ...
}
