laravel实现AMQP(rabbitmq)生产者以及消费者

基于php-amqplib/php-amqplib组件适配laravel框架的amqp封装库

支持便捷可配置的队列工作模式官网详情

在此基础上可支持延迟消息、死信队列等机制。

环境要求：

PHP版本: ^7.3|^8.0

需要开启的扩展: socket

其他:

如果需要实现延迟任务需要安装对应版本的rabbitmq延迟插件，以rabbitmq3.9.0版本为例:

wget https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/3.9.0/rabbitmq_delayed_message_exchange-3.9.0.ez
cp rabbitmq_delayed_message_exchange-3.9.0.ez /opt/rabbitmq/plugins/
rabbitmq-plugins enable rabbitmq_delayed_message_exchange

用法：

第一步安装组件：

composer require sai97/laravel-amqp

第二步发布服务以及配置：

php artisan vendor:publish --provider="Sai97\LaravelAmqp\AmqpQueueProviders"

执行完后会分别在app/config目录下生成amqp.php(amqp连接配置等)、app/QueueJob/DefaultQueueJob.php(默认队列任务)

amqp.php

<?phpuse App\QueueJob\DefaultQueueJob;return ["connection" => ["default" => ["host" => env("AMQP_HOST", "127.0.0.1"),"port" => env("AMQP_PORT", 5672),"user" => env("AMQP_USER", "root"),"password" => env("AMQP_PASSWORD", "root")]],"event" => ["default" => DefaultQueueJob::class,]
];

connection为amqp连接配置，可根据自身业务去调整，完全对应php-amqplib/php-amqplib相关配置项， event是队列实例标识，最好和connection用相同的key以便管理。

目前可支持相关接口项：

 //获取连接名称public function getConnectName(): string;//获取交换机名称public function getExchangeName(): string;//获取交换机类型public function getExchangeType(): string;//获取队列名称public function getQueueName(): string;//获取路由KEYpublic function getRoutingKey(): string;//获取ContentTypepublic function getContentType(): string;//是否开启死信模式public function isDeadLetter(): bool;//获取死信交换机名称public function getDeadLetterExchangeName(): string;//获取死信路由KEYpublic function getDeadLetterRoutingKey(): string;//获取死信队列名称public function getDeadLetterQueueName(): string;//是否开启延迟任务public function isDelay(): bool;//获取延迟任务过期时长public function getDelayTTL(): int;//获取队列附加参数public function getQueueArgs(): array;//获取回调函数public function getCallback(): callable;//是否自动提交ACKpublic function isAutoAck(): bool;

当然你也可以自定义队列实例，只要继承Sai97\LaravelAmqp\Queue基类即可，具体功能配置参数参考Sai97\LaravelAmqp\QueueInterface。

代码示例:

生产者:

$message = "This is message...";
$amqpQueueServices = new AmqpQueueServices(QueueFactory::getInstance(DefaultQueueJob::class));
$amqpQueueServices->producer($message);

消费者:

利用laravel自带的Command去定义一个RabbitMQWorker自定义命令行，仅需要定义一次，后续只需要更改amqp.php配置文件添加不同的队列实例绑定关系即可，以下是RabbitMQWorker演示代码：

<?phpnamespace App\Console\Commands;use Illuminate\Console\Command;
use Sai97\LaravelAmqp\AmqpQueueServices;
use Sai97\LaravelAmqp\QueueFactory;class RabbitMQWorker extends Command
{/*** The name and signature of the console command.** @var string*/protected $signature = 'rabbitmq:worker {event}';/*** The console command description.** @var string*/protected $description = 'rabbitmq worker 消费进程';/*** Create a new command instance.** @return void*/public function __construct(){parent::__construct();}/*** Execute the console command.** @return mixed*/public function handle(){try {$event = $this->argument("event");$eventConfig = config("amqp.event");if (!isset($eventConfig[$event]) || empty($entity = $eventConfig[$event])) {return $this->error("未知的事件: {$event}");}$this->info("rabbitmq worker of event[{$event}] process start ...");$amqpQueueServices = new AmqpQueueServices(QueueFactory::getInstance($entity));$amqpQueueServices->consumer();} catch (\Throwable $throwable) {$event = $event ?? "";$this->error($throwable->getFile() . " [{$throwable->getLine()}]");return $this->error("rabbitmq worker of event[{$event}] process error:{$throwable->getMessage()}");}$this->info("rabbitmq worker of event[{$event}] process stop ...");}
}

完成RabbitMQWorker消费者命令后，我们只需执行php artisan rabbitmq:worker default 完成监听，其中default是可变的，请根据的amqp.php配置中的队列实例绑定标识去输入。

因为队列的消费者都需要是守护进程，所以我们可以依托supervisord进程管理器去定义RabbitMQWorker消费者命令，这样可以保证进程可后台允许以及重启启动等，以下是supervisord.conf配置文件示例：

[program:rabbitmq-worker-default]
#process_name=%(program_name)s_%(process_num)d
process_name=worker_%(process_num)d
numprocs=3
command=/usr/local/bin/php /app/www/laravel8/artisan rabbitmq:worker default
autostart=true
autorestart=true
startretries=3
priority=3
stdout_logfile=/var/log/rabbitmq-worker-default.log
redirect_stderr=true

搭配supervisord来进行管理消费者进程有许多便捷的方面：
