NAME

Mojo::RabbitMQ::Client::Publisher - simple Mojo::RabbitMQ::Client based publisher

SYNOPSIS

  use Mojo::RabbitMQ::Client::Publisher;
  my $publisher = Mojo::RabbitMQ::Client::Publisher->new(
    url => 'amqp://guest:guest@127.0.0.1:5672/?exchange=mojo&routing_key=mojo'
  );

  $publisher->publish_p(
    {encode => { to => 'json'}},
    routing_key => 'mojo_mq'
  )->then(sub {
    say "Message published";
  })->catch(sub {
    die "Publishing failed"
  })->wait;

DESCRIPTION

ATTRIBUTES

Mojo::RabbitMQ::Client::Publisher has following attributes.

url

Sets all connection parameters in one string, according to specification from https://www.rabbitmq.com/uri-spec.html.

For detailed description please see Mojo::RabbitMQ::Client#url.

METHODS

Mojo::RabbitMQ::Client::Publisher implements only single method.

publish_p

  $publisher->publish_p('simple plain text body');

  $publisher->publish_p({ some => 'json' });

  $publisher->publish_p($body, { header => 'content' }, routing_key => 'mojo', mandatory => 1);

Method signature

  publish_p($body!, \%headers?, *@params)
body

First argument is mandatory body content of published message. Any reference passed here will be encoded as JSON and accordingly content_type header will be set to application/json.

headers

If second argument is a HASHREF it will be merged to message headers.

params

Any other arguments will be considered key/value pairs and passed to the Client's publish method as arguments overriding everything besides body argument.

So this:

  $publisher->publish({ json => 'object' }, { header => 'content' });

is similar to this:

  $publisher->publish({ json => 'object' }, header => { header => 'content' });

But beware - headers passed as a HASHREF get merged into the header constructed by the Publisher, but params override values; so if you pass header as a param like this, it will override the header constructed by the Publisher, and the message will lack the content_type header, even though you passed a reference as the body argument! With the first example, the content_type header would be included.
