Laravel使用RabbitMQ的方法示例

這篇文章主要介紹了Laravel使用RabbitMQ的方法示例，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨着小編來一起學習學習吧

導語

RabbitMQ 想必大家都有了解，不做多介紹來。這裏實現的是用 RabbitMQ 作爲 Larvel 隊列的驅動，替代 Redis。下面以 Laradock 中安裝示例。

安裝

1. 切換到 laradock 目錄，將 .env 中關於 INSTALL_AMQP 的值修改爲 true
2. docker-compose stop workspace php-fpm php-worker
3. docker-compose build workspace php-fpm php-worker rabbitmq
4. docker-compose up -d workspace php-fpm php-worker rabbitmq

擴展包安裝以及配置

1. 進入到 workspace 容器中，在項目目錄安裝擴展包 composer require vladimir-yuldashev/laravel-queue-rabbitmq
2. 接下來在 config/queue.php 文件中 connections 添加 rabbitmq 配置，根據情況自行修改

'rabbitmq' => [

  'driver' => 'rabbitmq',

  /*
   * Set to "horizon" if you wish to use Laravel Horizon.
   */
  'worker' => env('RABBITMQ_WORKER', 'default'),

  'dsn' => env('RABBITMQ_DSN', null),

  /*
   * Could be one a class that implements \Interop\Amqp\AmqpConnectionFactory for example:
   * - \EnqueueAmqpExt\AmqpConnectionFactory if you install enqueue/amqp-ext
   * - \EnqueueAmqpLib\AmqpConnectionFactory if you install enqueue/amqp-lib
   * - \EnqueueAmqpBunny\AmqpConnectionFactory if you install enqueue/amqp-bunny
   */

  'factory_class' => Enqueue\AmqpLib\AmqpConnectionFactory::class,

  'host' => env('RABBITMQ_HOST', '127.0.0.1'),
  'port' => env('RABBITMQ_PORT', 5672),

  'vhost' => env('RABBITMQ_VHOST', '/'),
  'login' => env('RABBITMQ_LOGIN', 'guest'),
  'password' => env('RABBITMQ_PASSWORD', 'guest'),

  'queue' => env('RABBITMQ_QUEUE', 'default'),

  'options' => [

    'exchange' => [

      'name' => env('RABBITMQ_EXCHANGE_NAME'),

      /*
       * Determine if exchange should be created if it does not exist.
       */

      'declare' => env('RABBITMQ_EXCHANGE_DECLARE', true),

      /*
       * Read more about possible values at https://www.rabbitmq.com/tutorials/amqp-concepts.html
       */

      'type' => env('RABBITMQ_EXCHANGE_TYPE', \Interop\Amqp\AmqpTopic::TYPE_DIRECT),
      'passive' => env('RABBITMQ_EXCHANGE_PASSIVE', false),
      'durable' => env('RABBITMQ_EXCHANGE_DURABLE', true),
      'auto_delete' => env('RABBITMQ_EXCHANGE_AUTODELETE', false),
      'arguments' => env('RABBITMQ_EXCHANGE_ARGUMENTS'),
    ],

    'queue' => [

      /*
       * Determine if queue should be created if it does not exist.
       */

      'declare' => env('RABBITMQ_QUEUE_DECLARE', true),

      /*
       * Determine if queue should be binded to the exchange created.
       */

      'bind' => env('RABBITMQ_QUEUE_DECLARE_BIND', true),

      /*
       * Read more about possible values at https://www.rabbitmq.com/tutorials/amqp-concepts.html
       */

      'passive' => env('RABBITMQ_QUEUE_PASSIVE', false),
      'durable' => env('RABBITMQ_QUEUE_DURABLE', true),
      'exclusive' => env('RABBITMQ_QUEUE_EXCLUSIVE', false),
      'auto_delete' => env('RABBITMQ_QUEUE_AUTODELETE', false),
      'arguments' => env('RABBITMQ_QUEUE_ARGUMENTS'),
    ],
  ],

  /*
   * Determine the number of seconds to sleep if there's an error communicating with rabbitmq
   * If set to false, it'll throw an exception rather than doing the sleep for X seconds.
   */

  'sleep_on_error' => env('RABBITMQ_ERROR_SLEEP', 5),

  /*
   * Optional SSL params if an SSL connection is used
   * Using an SSL connection will also require to configure your RabbitMQ to enable SSL. More details can be founds here: https://www.rabbitmq.com/ssl.html
   */

  'ssl_params' => [
    'ssl_on' => env('RABBITMQ_SSL', false),
    'cafile' => env('RABBITMQ_SSL_CAFILE', null),
    'local_cert' => env('RABBITMQ_SSL_LOCALCERT', null),
    'local_key' => env('RABBITMQ_SSL_LOCALKEY', null),
    'verify_peer' => env('RABBITMQ_SSL_VERIFY_PEER', true),
    'passphrase' => env('RABBITMQ_SSL_PASSPHRASE', null),
  ],

],

在 .env 中修改 QUEUE_CONNECTION 爲 rabbitmq ，並添加以下值

RABBITMQ_WORKER=horizon
RABBITMQ_HOST=rabbitmq
RABBITMQ_PORT=5672
RABBITMQ_LOGIN=guest
RABBITMQ_PASSWORD=guest
RABBITMQ_QUEUE=default

有兩個值說明一下，因爲是在 Laradock 中，所以 RABBITMQ_HOST 設置爲 rabbitmq ；如果之前使用了Laravel Horizon，那麼 RABBITMQ_WORKER 的設置爲 horizon 就可以了。
