laravel 5.6 使用RabbitMQ作为消息中间件

1、Composer安装laravel-queue-rabbitmq
composer require vladimir-yuldashev/laravel-queue-rabbitmq
2、在config/app.php文件中，providers中添加：
VladimirYuldashev\LaravelQueueRabbitMQ\LaravelQueueRabbitMQServiceProvider::class,
3、在app/config/queue.php配置文件中的connections数组中加入以下配置

'rabbitmq' => [

            'driver' => 'rabbitmq', '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), ], ],

4、修改 .env 文件

QUEUE_CONNECTION=rabbitmq    #这个配置env一般会有先找到修改为这个

#以下是新增配置

RABBITMQ_HOST=rabbitmq #mq的服务器地址，我这里用的是laradock，具体的就具体修改咯 RABBITMQ_PORT=5672 #mq的端口 RABBITMQ_VHOST=/ RABBITMQ_LOGIN=guest #mq的登录名 RABBITMQ_PASSWORD=guest #mq的密码 RABBITMQ_QUEUE=queue_name #mq的队列名称

5、创建任务类
php artisan make:job Queue
执行之后会生成一个文件app/Jobs/Queue.php

例子：

namespace App\Jobs; use App\Entities\Posts; use Illuminate\Bus\Queueable; use Illuminate\Foundation\Bus\Dispatchable; use Illuminate\Queue\SerializesModels; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Queue\ShouldQueue; class Queue implements ShouldQueue { use Dispatchable, InteractsWithQueue, Queueable, SerializesModels; private $data; /** * Queue constructor. * @param $data */ public function __construct($data) { $this->data = $data; } /** * Execute the job. * * @return void */ public function handle() { try{ $insert = [ 'title'=>$this->data->title, 'author_id'=>$this->data->author_id, 'content'=>$this->data->content, 'description'=>$this->data->description, ]; $result = Posts::create($insert); echo json_encode(['code' => 200, 'msg' => $result]); }catch (\Exception $exception) { echo json_encode(['code'=>0,'msg'=>$exception->getMessage()]); } } }

6、生产，把数据放进mq队列

namespace App\Http\Controllers; use App\Entities\CostaNews; use App\Jobs\Queue; class IndexController extends Controller { public function index() { $data = CostaNews::get(); foreach ($data as $item) { $this->dispatch(new Queue($item)); } return response()->json(['code'=>0, 'msg'=>"success"]); } }

7、消费队列
执行命令进行消费：
php artisan queue:work rabbitmq
效果如下：

root@9e99cf9fba73:/var/www/blog# php artisan queue:work rabbitmq [2018-12-24 07:34:32][5c208bf66e63b3.56379160] Processing: App\Jobs\Queue {"code":200,"msg":{"title":1,"author_id":2,"content":"\u5185\u5bb9","description":"\u63cf\u8ff0","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":1}}[2018-12-24 07:34:32][5c208bf66e63b3.56379160] Processed: App\Jobs\Queue [2018-12-24 07:34:32][5c208bf66ff7c3.20969590] Processing: App\Jobs\Queue {"code":200,"msg":{"title":2,"author_id":2,"content":"\u5185\u5bb92","description":"\u63cf\u8ff02","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":2}}[2018-12-24 07:34:32][5c208bf66ff7c3.20969590] Processed: App\Jobs\Queue [2018-12-24 07:34:32][5c208bf6702695.93123122] Processing: App\Jobs\Queue {"code":200,"msg":{"title":3,"author_id":2,"content":"\u5185\u5bb93","description":"\u63cf\u8ff03","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":3}}[2018-12-24 07:34:32][5c208bf6702695.93123122] Processed: App\Jobs\Queue [2018-12-24 07:34:32][5c208bf6706e24.78015170] Processing: App\Jobs\Queue {"code":200,"msg":{"title":4,"author_id":2,"content":"\u5185\u5bb94","description":"\u63cf\u8ff04","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":4}}[2018-12-24 07:34:32][5c208bf6706e24.78015170] Processed: App\Jobs\Queue [2018-12-24 07:34:32][5c208bf6709be0.07998731] Processing: App\Jobs\Queue {"code":200,"msg":{"title":5,"author_id":2,"content":"\u5185\u5bb95","description":"\u63cf\u8ff05","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":5}}[2018-12-24 07:34:32][5c208bf6709be0.07998731] Processed: App\Jobs\Queue

注意：使用这个laravel-queue-rabbitmq这个包需要开启sockets拓展，不然会报错
