laravel8-rabbitmq消息队列-实时监听跨服务器消息

使用场景介绍：

1）用于实时监听远程服务器发出的消息（json格式消息），接受并更新消息状态，存储到本地服务器

2）环境：lNMP（laravel8）

3）服务器需要开启rabbitmq驱动队列

1、composer安装rabbitmq扩展包

vladimir-yuldashev/laravel-queue-rabbitmq

参考文档：[https://blog.csdn.net/u012321434/article/details/126246141\]

2、安装配置文件

1. 打开app/config/queue.php中connections数组中添加以下代码，根据实际情况填写相关配置信息

   'rabbitmq' => [
   'driver' => 'rabbitmq',
   'queue' => env('RABBITMQ_QUEUE', 'default'),
   'connection' => PhpAmqpLib\Connection\AMQPLazyConnection::class,
   'hosts' => [
   [
   'host' => env('RABBITMQ_HOST', '127.0.0.1'),
   'port' => env('RABBITMQ_PORT', 5672),
   'user' => env('RABBITMQ_USER', 'guest'),
   'password' => env('RABBITMQ_PASSWORD', 'guest'),
   'vhost' => env('RABBITMQ_VHOST', '/'),
   ],
   ],
   'options' => [
   'ssl_options' => [
   'verify_peer' => env('RABBITMQ_SSL_VERIFY_PEER', false),
   ],
   'queue' => [
   //此处直接添加到自定义的job任务中
   'job' => App\Jobs\Rabbitmq\RabbitMQJob::class,

                    //以下配置是rabbitmq 广播模式(direct)
                    'exchange' => 'amq',
                    'exchange_type' => 'direct',
                    'exchange_routing_key' => '',
                ],
            ],
   
            /*
             * Set to "horizon" if you wish to use Laravel Horizon.
             */
            'worker' => env('RABBITMQ_WORKER', 'default'),
        ],

2. .env文件中配置相关参数信息

   RABBITMQ_HOST=127.0.0.1
   RABBITMQ_PORT=5672
   RABBITMQ_USER=testuser
   RABBITMQ_PASSWORD=test
   RABBITMQ_VHOST=/project
   RABBITMQ_QUEUE=que_project

3. 在app/config/logging.php文件channels选项中添加自定义log日志，记录报错日志信息

   'rabbitmq' => [
   'driver' => 'daily',
   'path' => storage_path('logs/rabbitmq.log'),
   'level' => env('LOG_LEVEL', 'debug'),
   'days' => 14,
   ],

4. RabbitMQJob.php

   namespace App\Jobs\Rabbitmq;

   use Illuminate\Support\Str;
   use VladimirYuldashev\LaravelQueueRabbitMQ\Queue\Jobs\RabbitMQJob as BaseJob;
   use App\Services\Rabbitmq\RabbitmqService;

   class RabbitMQJob extends BaseJob
   {
   public tries = 1; public timeout = 3600;
   public $maxExceptions = 3;

    public function fire()
    {
        $payload = $this->payload();
        (new RabbitmqService())->handle($payload['data']);
        $this->delete();
    }
   
    /**
     * Get the decoded body of the job.
     * 接收消息体并自定义处理
     * @return array
     */
    public function payload()
    {
        return [
            'uuid' => (string) Str::uuid(),
            'job'  => '\App\Services\Rabbitmq\RabbitmqService@handle',
            'maxTries' => $this->tries,
            'maxExceptions' => $this->maxExceptions,
            'timeout' => $this->timeout,
            'data' => json_decode($this->getRawBody(), true)
        ];
    }
   
    /**
     * Process an exception that caused the job to fail.
     *
     * @param  \Throwable|null  $e
     * @return void
     */
    protected function failed($e)
    {
        (new RabbitmqService())->failed($e);
   
    }

   }

5. RabbitmqService.php

   namespace App\Services\Rabbitmq;

   use Illuminate\Support\Facades\Log;

   class RabbitmqService
   {
   protected logName = 'rabbitmq'; protected connection;
   protected channel; public messageService;

    /**
     * 处理消息状态
     * @param $message .接收到的消息
     * @return bool
     */
    public function handle($message='')
    {
        //1.判断接收的消息情况
        Log::channel($this->logName)->info('接收的消息体：'.json_encode($message));
    	//接收到的消息
        $message = json_decode(json_encode($message), true);
        //2.消息自定义处理
    		
    }
   
    /**
     * 异常扑获
     * @param \Exception $exception
     */
    public function failed(\Exception $exception)
    {
        Log::channel($this->logName)->info('异常：'.json_encode($exception->getMessage()));
    }

   }

6. 服务器开启rabbitmq队列驱动，开始监听消息

   php artisan queue:work rabbitmq
