逻辑：
创建连接-->创建channel-->创建交换机-->创建队列-->绑定交换机/队列/路由键-->接收消息
生产者：
$conn_args = array(
'host' => '127.0.0.1',
'port' => '5672',
'login' => 'gedai',
'password' => 'gedai',
'vhost'=>'/credithc'
);
$e_name = 'CREDITHC_CS'; //交换机名
$q_name = 'to_tel_sales'; //无需队列名
$k_route = 'to_tel_sales'; //路由key
//创建连接和channel
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
die("Cannot connect to the broker!\n");
}
$channel = new AMQPChannel($conn);
//消息内容
$message = date("Y-m-d H:i:s") . "TEST send RabbitMQ!";
//创建交换机对象
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
//发送消息
//$channel->startTransaction(); //开始事务
for($i=0; $i<5; ++$i){
echo "Send Message:".$ex->publish($message, $k_route)."\n";
}
//$channel->commitTransaction(); //提交事务
消费者：
//配置信息
$conn_args = array(
'host' => '10.100.13.142',
'port' => '5672',
'login' => 'gedai',
'password' => 'gedai',
'vhost'=>'/credithc'
);
$e_name = 'CREDITHC_CS'; //交换机名
$q_name = 'to_tel_sales'; //队列名
$k_route = 'to_tel_sales'; //路由key
//创建连接和channel
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
die("Cannot connect to the broker!\n");
}
$channel = new AMQPChannel($conn);
//创建交换机
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化
// echo "Exchange Status:".$ex->declare()."\n";
//创建队列
$q = new AMQPQueue($channel);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE); //持久化
echo "Message Total:".$q->declareQueue()."\n";
//绑定交换机与队列，并指定路由键
echo 'Queue Bind: '.$q->bind($e_name, $k_route)."\n";
//阻塞模式接收消息
echo "Message:\n";
while(True){
$q->consume('processMessage');
// $q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答
}
//get获取
$conn->disconnect();
function processMessage($envelope, $queue) {
$msg = $envelope->getBody();
echo date("Y-m-d H:i:s") . $msg."\n"; //处理消息
$queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答
}
queue对象有两个方法可用于取消息：consume和get。
前者是阻塞的，无消息时会被挂起，适合循环中使用；
后者则是非阻塞的，取消息时有则取，无则返回false。
