NAME

Dancer::Plugin::RESTModel - REST model class for Dancer apps

SYNOPSIS

set the REST endpoint in your Dancer configuration file:

plugins:
  RESTModel:
    MyData:
      server: http://localhost:5000
      type: application/json
      clientattrs:
        timeout: 5

then use it from any of your routes/controllers:

use Dancer ':syntax';
use Dancer::Plugin::RESTModel;

get '/' => sub {
    my $res = model('MyData')->post( 'foo/bar/baz', { meep => 'moop' } );

    my $code = $res->code; # e.g. 200 
    my $data = $res->data;

    ...
};

DESCRIPTION

This plugin lets you talk to a REST server as a separate model from within your Dancer app. It is useful for keeping your API decoupled from your app while still being able to manage it through the configuration file.

It is a thin wrapper over Role::REST::Client.

INTERFACE

model()

The exported model() function returns a REST Model object which provides the standard HTTP 1.1 verbs as methods:

post
get
put
delete
options
head

All methods take these parameters:

  • url - the REST service being accessed

  • data - The data structure to send (hashref, arrayref). The data will be encoded according to the value of the type attribute

  • args - optional hashref with arguments to augment the way the call is handled. It currently provides the 'deserializer' key to change the deserializer if you know that the response's content-type is incorrect, and also the 'preserve_headers' which, if set to true, will keep the headers between calls:

    my $res = model('MyData')->post(
    'users/123',
    { foo => 'bar' },
    { deserializer => 'application/yaml', preserve_headers => 1 },
);

The third parameter, args, is an optional hashref which lets you give extra information to the object. It currently provides
