本文详细介绍了RabbitMQ中Direct和Fanout两种消息传递模式，并提供了具体的PHP实现示例。Direct模式允许通过指定的路由键精确投递消息，而Fanout模式则将消息广播到所有绑定的队列中。

direct类型：

provider 端代码

//设置你的连接
$conn_args = array('host' => 'localhost', 'port' => '5672', 'login' => 'guest', 'password' => 'guest','vhost' =>'/');
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
	echo "连接建立失败";
	exit;
}
$channel = new AMQPChannel($conn);
$e_name = 'e_exchange'; //交换机名
$key = 'key_one'; //路由key
//创建交换机
$ex = new AMQPExchange($channel);
$ex->setName($e_name);//设置交换机名称
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化

$ex->declareExchange(); //声明交换机

echo $ex->publish('hello world',$key)."\n";
}

consumer 端代码

$key='key_one';
//连接RabbitMQ
$conn_args = array( 'host'=>'127.0.0.1' , 'port'=> '5672', 'login'=>'guest' , 'password'=> 'guest','vhost' =>'/');
$conn = new AMQPConnection($conn_args);
$conn->connect();

$channel = new AMQPChannel($conn);
$q = new AMQPQueue($channel);
$q->setName('queue'); //设置队列名称
$q->setFlags(AMQP_DURABLE); //持久化设置
$q->declareQueue();//声明队列


$q->bind('e_exchange',$key); //绑定交换机

while(True){

	$q->consume('consumer'); //回调方法为consumer
}



$conn->disconnect();

function consumer($envelope, $queue) {

	$msg = $envelope->getBody();
	echo $msg."\n"; //处理消息
	$queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答

fanout 模式

provider

/设置你的连接
$conn_args = array('host' => 'localhost', 'port' => '5672', 'login' => 'guest', 'password' => 'guest','vhost' =>'/');
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
	echo "连接建立失败";
	exit;
}
$channel = new AMQPChannel($conn);
$e_name = 'ex_fanout'; //交换机名

//创建交换机
$ex = new AMQPExchange($channel);
$ex->setName($e_name);//设置交换机名称
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化

$ex->declareExchange(); //声明交换机

echo $ex->publish('hello world')."\n";

consumer

//连接RabbitMQ
$conn_args = array( 'host'=>'127.0.0.1' , 'port'=> '5672', 'login'=>'guest' , 'password'=> 'guest','vhost' =>'/');
$conn = new AMQPConnection($conn_args);
$conn->connect();

$channel = new AMQPChannel($conn);
$q = new AMQPQueue($channel);
$q->setName('queue_one'); //设置队列名称
$q->setFlags(AMQP_DURABLE); //持久化设置
$q->declareQueue();//声明队列


$q->bind('ex_fanout'); //绑定交换机

while(True){

	$q->consume('consumer'); //回调方法为consumer
}



$conn->disconnect();

function consumer($envelope, $queue) {

	$msg = $envelope->getBody();
	echo $msg."\n"; //处理消息
	$queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答
}
