        # controller
        sub foo : Local {
                my ($self, $c) = @_;
                my $res = $c->model('MyData')->post('/foo/bar/baz', {foo => 'bar'});
                my $code = $res->code;

                ...
        }

DESCRIPTION

This REST Client role makes REST connectivety easy.

Role::REST::Client will handle encoding and decoding when using the HTTP verbs.

        GET
        PUT
        POST
        DELETE
        OPTIONS
        HEAD

Currently Role::REST::Client supports these encodings

        application/json
        application/x-www-form-urlencoded
        application/xml
        application/yaml

x-www-form-urlencoded only works for GET and POST, and only for encoding, not decoding.

NAME

Role::REST::Client - REST Client Role

METHODS

methods

Role::REST::Client implements the standard HTTP 1.1 verbs as methods

        post
        get
        head
        put
        delete
        options

All methods take these parameters

        url - The REST service
        data - The data structure (hashref, arrayref) to send. The data will be encoded
                according to the value of the I<type> attribute.
        args - hashref with arguments to augment the way the call is handled.

args - the optional argument parameter can have these entries

        deserializer - if you KNOW that the content-type of the response is incorrect,
        you can supply the correct content type, like
        my $res = $self->post('/foo/bar/baz', {foo => 'bar'}, {deserializer => 'application/yaml'});

        preserve_headers - set this to true if you want to keep the headers between calls

All methods return a response object dictated by _rest_response_class. Set to Role::REST::Client::Response by default.

ATTRIBUTES

user_agent

  sub _build_user_agent { HTTP::Thin->new }

A User Agent object which has a ->request method suitably compatible with HTTP::Tiny. It should accept arguments like this: $ua->request($method, $uri, $opts), and needs to return a hashref as HTTP::Tiny does, or an HTTP::Response object. To set your own default, use a _build_user_agent method.

server

URL of the REST server.

e.g. 'http://localhost:3000'

type

MIME Content-Type header,

e.g. application/json

httpheaders

  $self->set_header('Header' => 'foo', ... );
  $self->get_header('Header-Name');
  $self->has_no_headers;
  $self->clear_headers;

You can set any http header you like with set_header, e.g. $self->set_header($key, $value) but the content-type header will be overridden.

persistent_headers

  $self->set_persistent_header('Header' => 'foo', ... );
  $self->get_persistent_header('Header-Name');
  $self->has_no_persistent_headers;
  $self->clear_persistent_headers;

A hashref containing headers you want to use for all requests. Use the methods described above to manipulate it.

To set your own defaults, override the default or call set_persistent_header() in your BUILD method.

  has '+persistent_headers' => (
    default => sub { ... },
  );

clientattrs

Attributes to feed the user agent object (which defaults to HTTP::Thin)

e.g. {timeout => 10}
