NAME¶
Dancer::Serializer::Mutable - Serialize and deserialize content using the
appropriate HTTP header
VERSION¶
version 1.3132
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 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
serializer | content types
----------------------------------------------------------
Dancer::Serializer::YAML | text/x-yaml, text/html
Dancer::Serializer::XML | text/xml
Dancer::Serializer::JSON | text/x-json, application/json
EXPORTABLE FUNCTIONS¶
template_or_serialize( $template, $data, $options )¶
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" 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,
};
};
INTERNAL METHODS¶
The following methods are used internally by "Dancer" 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, XML, 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, XML, JSON.
content_type¶
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".
