RabbitMQ是一款消息队列中间件。他提供了几乎覆盖所有语言的SDK与文档,简直强大的不的了。要详细的去了解学习RabbitMQ,我建议还是看官方文档吧。http://www.rabbitmq.com/getstarted.html
消息队列有以下几个基本用途
消息队列的这几个用途我会在后续的文章以真实案例去表述
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel ();
与链接一个数据库概念差不多
$channel->queue_declare ('hello');
创建多个队列与创建多个数据库一样,hello则是队列名
$message = new AMQPMessage('Hello World!');
$channel->basic_publish ($message, '', 'hello');
hello 是上面创建的队列声明
$channel->close ();
$connection->close ();
释放资源
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel ();
与链接一个数据库概念差不多
$channel->queue_declare ('hello');
创建多个队列与创建多个数据库一样,hello则是队列名
$channel->basic_consume ('hello', '', false, true, false, false, function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
});
通过回调函数处理消息队列
while (count ($channel->callbacks)) {
$channel->wait ();
}
无消息时,挂起保持等待状态
$channel->close ();
$connection->close ();
释放资源
完整的按钮则是上面所有代码的整理
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel ();
$channel->queue_declare ('hello');
$message = new AMQPMessage('Hello World!');
$channel->basic_publish ($message, '', 'hello');
$channel->close ();
$connection->close ();
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel ();
$channel->queue_declare ('hello');
// basic_consume 方法第7个方法可以直接传入函数
$channel->basic_consume ('hello', '', false, true, false, false, function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
});
while (count ($channel->callbacks)) {
$channel->wait ();
}
$channel->close ();
$connection->close ();
php {生产者}.php
php {消费者}.php
RabbitMQ支持多线程处理消息队列,所有你可以开启多个消费者去执行消息队列内的任务。你可以像我这样
如果你感觉RabbitMQ这玩意还需要安装啥的感觉特麻烦,那你可以看下我的Laravel队列如何简单的玩起来。 https://segmentfault.com/a/1190000010604659
感谢你看完我这篇文章,纯手记的一篇文章,官方文档对新手的理解造成很多的误解,所以整理此文档,尽量避免新手“进”坑吧。对文章有什么问题或疑问,欢迎在评论区留言。谢谢
