php rabbitmq yii2,yii2 使用 rabbitmq 扩展监听、发送消息
RabbitMQ是一个在AMQP基础上实现的企业级消息系统。何谓消息系统，就是消息队列系统，消息队列是“消费-生产者模型”的一个典型的代表，一端往消息队列中不断写入消息，而另一端则可以读取或者订阅队列中的消息。
在开始前确保php安装了amqp扩展，如果没有安装，可进行安装。
安装可参考：php 安装 amqp 扩展
扩展地址
扩展安装
composer require mikemadisonweb/yii2-rabbitmq "1.7.0"
配置及使用
1.新建rabbitmq.php文件，单独放其配置,在配置前，要先保证，rabbitmq的服务已经配置好
/**
* rabbitmq的配置
*/
$rabbitMq = [
'on before_consume' => function ($event){
if (isset(\Yii::$app->db)) {
$db = \Yii::$app->db;
if ($db->getIsActive()) {
$db->close();
}
$db->open();
}
},
'logger' => [
'enable' => true,
'category' => 'amqp',
'print_console' => true,
],
'class' => 'mikemadisonweb\rabbitmq\Configuration',
'connections' => [
'default' => [
'host' => '127.0.0.1',
'port' => '5672',
'user' => '你的登陆账号',
'password' => '你的密码',
'vhost' => '虚拟主机',
'heartbeat' => 0,
],
],
'producers' => [ //生产者，发送消息需要在次配置
'import_data' => [
'connection' => 'default',
'exchange_options' => [
'name' => 'import_data',
'type' => 'direct',
],
'queue_options' => [
'name' => 'import_data', // Queue name which will be binded to the exchange adove
'routing_keys' => ['import_data'], // Your custom options
'durable' => true,
'auto_delete' => false,
],
],
],
'consumers' => [ //消费者，接受消息需要再次配置
'import_data' => [
'connection' => 'default',
'exchange_options' => [
'name' => 'import_data', // Name of exchange to declare
'type' => 'direct', // Type of exchange
],
'queue_options' => [
'name' => 'import_data', // Queue name which will be binded to the exchange adove
'routing_keys' => ['import_data'], // Your custom options
'durable' => true,
'auto_delete' => false,
],
'callback' => \common\components\rabbitmq\ImportDataConsumer::class,
],
],
];
return $rabbitMq;
2.在主配置文件,common/config/main.php中添加组件
'components' => [
"rabbitmq" => require(__DIR__ . '/rabbitmq.php'),
],
3.配置回调
在\common\components\rabbitmq目录下，配置回调类
namespace common\components\rabbitmq;
use mikemadisonweb\rabbitmq\components\ConsumerInterface;
use PhpAmqpLib\Message\AMQPMessage;
class ImportDataConsumer implements ConsumerInterface{
/**
* @param AMQPMessage $msg
* @return bool
*/
public function execute(AMQPMessage $msg){
$data = unserialize($msg->body);
var_dump($data);
echo '我刚消费了消息';
return ConsumerInterface::MSG_ACK;
}
}
4.配置启动命令 在console/config/main.php中添加启动配置
'controllerMap' => [
'rabbitmq-consumer' => \mikemadisonweb\rabbitmq\controllers\ConsumerController::class,
'rabbitmq-producer' => \mikemadisonweb\rabbitmq\controllers\ProducerController::class,
],
5.启动命令
yii rabbitmq-consumer/single import_data -m=10
6.发送消息
\Yii::$app->rabbitmq->load();
$producer = \Yii::$container->get(sprintf('rabbit_mq.producer.%s', 'import_data'));
$msg = serialize(['id' => rand(1,100), 'msg' => 'hello world']);
$producer->publish($msg, 'import_data');
7.消费消息,在第三步配置的回调类中
