• Robust messaging for applications• Easy to use• Runs on all major operating systems• Supports a huge number of developer

platforms• Open source and commercially supported• Multiplatform for Windows, Linux and Mac OS• Erlang

The Advanced Message Queuing Protocol (AMQP) is an open standard application layer protocol for message-oriented middleware. The defining features of AMQP are message orientation, queuing, routing (including point-to-point and publish-and-subscribe), reliability and security.

AMQP

To become the standard protocol for interoperability between all messaging

Características do RabbitMQ• Queue• Consumer

• Public/Subscriber• Exchange• Channel• Persitent

• Durável / Transiente• Atomicidade• Round-Robin• Acknolodge

• Ack/Nack• TTL (Time to Live)

Tipos de fila do RabbitMQ

• Basic• Work• Topic• Route• Fanout• RPC

Basic - RabbitMQ

P – ProducerC – ConsumerQueue in Red

The simplest thing that does something

Work - RabbitMQ

Distributing tasks among workers

Automatic - Round-Robin

Publish/Subscribe (FanOut)- RabbitMQ

Sending messages to many consumers at once

Exchange Types: direct, topic, headers and fanoutchannel.exchange_declare(exchange='direct_logs', type=‘fanout')

Routing - RabbitMQ

Receiving messages selectivelychannel.exchange_declare(exchange='direct_logs', type='direct')channel.basic_publish(exchange='direct_logs', routing_key=severity, body=message)

Topics - RabbitMQ

Receiving messages based on a patternchannel.exchange_declare(exchange='direct_logs',

type=‘topic')

RPC Async WorkFlow - RabbitMQ

Remote procedure call implementationDefine properties: CorrelationId and ReplyTo (QueueName to reply

message)

Install Client - RabbitMQ{ "require": { "php-amqplib/php-amqplib": "2.5.*" }}

$composer install or update

Fluxo da API de Autorização

Sending message with PHP

require_once __DIR__ . '/vendor/autoload.php';use PhpAmqpLib\Connection\AMQPStreamConnection;use PhpAmqpLib\Message\AMQPMessage;

$connection = new AMQPStreamConnection('localhost', 5672, 'guest',

'guest');$channel = $connection->channel();

Sending message with PHP

$channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello World!');$channel->basic_publish($msg, '', 'hello');

$channel->close();$connection->close();

Receiving message with PHP$callback = function($msg) { echo " [x] Received ", $msg->body, "\n"; };

$channel->basic_consume('hello', '', false, true, false, false, $callback);

while(count($channel->callbacks)) { $channel->wait();}

Sending message with C# .Netusing RabbitMQ.Client;

var factory = new ConnectionFactory() { HostName = "localhost"

};

using(var connection = factory.CreateConnection())using(var channel = connection.CreateModel()){ }

Sending message with C# .Netchannel.QueueDeclare(

queue: "hello", durable: false, exclusive: false, autoDelete: false, arguments: null);

Sending message with C# .Netvar body = Encoding.UTF8.GetBytes(message);

channel.BasicPublish(exchange: "", routingKey: "hello", basicProperties: null, body: body);
