QAMQP

Qt4/Qt5 implementation of AMQP 0.9.1.

Implement

Connection

work with socket connections

• start - start connection negotiation
• startok - select security mechanism and locale
• tune - propose connection tuning parameters
• tuneok - negotiate connection tuning parameters
• open - open connection to virtual host
• openok - signal that connection is ready
• close - request a connection close
• closeok - confirm a connection close

Channel

work with channels

• open - open a channel for use
• openok - signal that the channel is ready
• close - request a channel close
• closeok - confirm a channel close

Exchange

work with exchanges

• declare - verify exchange exists, create if needed
• declareok - confirm exchange declaration
• delete - delete an exchange
• deleteok - confirm deletion of an exchange

Queue

work with queues

• declare - declare queue, create if needed
• declareok - confirms a queue definition
• bind - bind queue to an exchange
• bindok - confirm bind successful
• unbind - unbind a queue from an exchange
• unbindok - confirm unbind successful
• purge - purge a queue
• purgeok - confirms a queue purge
• delete - delete a queue
• deleteok - confirm deletion of a queue

Basic

work with basic content

• qos - specify quality of service
• qosok - confirm the requested qos
• consume - start a queue consumer
• consumeok - confirm a new consumer
• publish - publish a message
• deliver - notify the client of a consumer message
• get - direct access to a queue
• getok - provide client with a message
• getempty - indicate no messages available
• ack - acknowledge one or more messages

Usage

Test::Test()	
{
	QUrl con(QString("amqp://guest:guest@localhost:5672/"));
	client_ = new QAMQP::Client(this);
	connect(client_, SIGNAL(connected()), this, SLOT(connected()));
	client_->open(con);
	exchange_ =  client_->createExchange("test.test2");
	queue_ = client_->createQueue("test.my_queue", exchange_->channelNumber());
		
	connect(queue_, SIGNAL(declared()), this, SLOT(declared()));
	connect(queue_, SIGNAL(messageReceived(QAMQP::Queue * )), this, SLOT(newMessage(QAMQP::Queue *)));	

}

void Test::connected()
{
	exchange_->declare("fanout");		
	queue_->declare();
	exchange_->bind(queue_);
}

void Test::declared()
{
	exchange_->publish("Hello world", exchange_->name());
	queue_->setQOS(0,10);
	queue_->setConsumerTag("qamqp-consumer");
	queue_->consume(QAMQP::Queue::coNoAck);
}

void Test::newMessage(QAMQP::Queue * q)
{
	while (q->hasMessage())
	{
		QAMQP::MessagePtr message = q->getMessage();
		qDebug("+ RECEIVE MESSAGE");
		qDebug("| Exchange-name: %s", qPrintable(message->exchangeName));
		qDebug("| Routing-key: %s", qPrintable(message->routeKey));
		qDebug("| Content-type: %s", qPrintable(message->property[QAMQP::Frame::Content::cpContentType].toString()));
		if(!q->noAck())
		{
			q->ack(message);
		}
	}
}
