php - 尝试 pushRaw 时出现 AMQP 错误：未定义的索引：名称

问题描述

我正在将 Laravel 从升级5.4.*到5.5.0. RabbitMQ 工作得非常好，5.4但现在当我尝试运行使用队列的功能时，它在日志中显示以下错误：

尝试 pushRaw 时出现 AMQP 错误：未定义的索引：名称

日志中没有其他信息。这是我的.env：

RABBITMQ_HOST=localhost
RABBITMQ_PORT=5672
RABBITMQ_VHOST=/
RABBITMQ_LOGIN=test
RABBITMQ_PASSWORD=test
RABBITMQ_QUEUE=reporting
RABBITMQ_JOB_QUEUE=dev

这是我的配置queue.php：

'worker' => [
    'driver' => 'rabbitmq',
    'factory_class' => Enqueue\AmqpLib\AmqpConnectionFactory::class,
    'host' => env('RABBITMQ_HOST'),
    'port' => env('RABBITMQ_PORT'),
    'vhost' => env('RABBITMQ_VHOST'),
    'login' => env('RABBITMQ_LOGIN'),
    'password' => env('RABBITMQ_PASSWORD'),
    'queue' => env('RABBITMQ_JOB_QUEUE'),

    'options' => [
        'exchange' => [
            'name' => env('RABBITMQ_EXCHANGE_NAME', null),
            /*
            * 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'),
        ],
    ],
],

这是RabbitMQin的版本composer.json：

"vladimir-yuldashev/laravel-queue-rabbitmq": "6.0.0",

我的 Laravel 版本是5.5.0. 我试图推入队列的任务是：

\Mail::to($user->email)->queue(new MailPriceRequest($priceRequests));

这里出了什么问题？有什么帮助吗？

编辑：

这是MailPriceRequest课程：

class MailPriceRequest extends Mailable implements ShouldQueue
{
    use Queueable, SerializesModels;

    /**
     * @var
     */
    public $title;

    /**
     * @var

    public $items;

    /**

    public $groupedPriceRequests = [];

    /**

    public $grouped;

    /**

    public $groupName = '';

    /**

    public $emailSubject;

    /**
     * MailPriceRequest constructor.
     * @param $transportOrders
     */
    public function __construct($priceRequests)
    {
        $this->items = $priceRequests;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        $this->setPriceRequests();
        $this->setTitle();
        $this->setGrouped();
        $this->setSubject();
        return $this->subject($this->emailSubject)->view('emails.price-requests.overview');
    }

    /**
     * @return $this
     */
    public function setSubject()
    {
        $this->emailSubject = $this->getOrderNumber();

        return $this;
    }

    /**
     * @return $this
     */
    public function setGrouped()
    {
        $this->grouped = $this->groupedPriceRequests;

        return $this;
    }

    /**
     * @return $this
     */
    public function setTitle()
    {
        $this->title = 'title';

        return $this;
    }

    /**
     * @return $this
     */
    public function setPriceRequests()
    {
        $this->groupByCarrier();

        return $this;
    }

    /**
     * @return $this
     */
    public function groupByCarrier()
    {
        $transformer = \App::make(PriceRequestMailTransformer::class);
        foreach ($this->items as $priceRequest) {
            if (!array_key_exists($priceRequest->carrier_name, $this->groupedPriceRequests)) {
                $this->groupedPriceRequests[$priceRequest->carrier_name] = [
                    'price_requests' => []
                ];
            }
            $transformed = $transformer->transform($priceRequest);

            $this->groupedPriceRequests[$priceRequest->carrier_name]['price_requests'][] = $transformed;
        }

        return $this;
    }

    /**
     * @return string|null
     */
    private function getOrderNumber()
    {
        if (count($this->items) > 1) {
            return ' - ' . $this->items->first()->order_number . ' - and more references';
        }

        if (count($this->items) == 1) {
            return ' - ' . $this->items->first()->order_number;
        }

        return null;
    }
}

解决方案

有关rabbitmq配置和在 Laravel .env 中设置的文档如下；

RABBITMQ_HOST=localhost
RABBITMQ_PORT=5672
RABBITMQ_VHOST=/
RABBITMQ_LOGIN=test
RABBITMQ_PASSWORD=test
RABBITMQ_QUEUE=reporting
RABBITMQ_JOB_QUEUE=dev
# Exchange name is a required field. 
RABBITMQ_EXCHANGE_NAME=yourexchangename

在您的 queue.php 文件中设置交换名称环境变量。

'worker' => [
    'driver' => 'rabbitmq',
    'factory_class' => Enqueue\AmqpLib\AmqpConnectionFactory::class,
    'host' => env('RABBITMQ_HOST'),
    'port' => env('RABBITMQ_PORT'),
    'vhost' => env('RABBITMQ_VHOST'),
    'login' => env('RABBITMQ_LOGIN'),
    'password' => env('RABBITMQ_PASSWORD'),
    'queue' => env('RABBITMQ_JOB_QUEUE'),

    'options' => [
        'exchange' => [
            // Exchange name is a required field. 
            'name' => env('RABBITMQ_EXCHANGE_NAME', null),
            /*
            * 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' => [
            'name' => env('RABBITMQ_EXCHANGE_NAME', env('RABBITMQ_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'),
        ],
    ],
],

        'worker' => env('RABBITMQ_WORKER', 'default'),

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

        /*
         * Could be one a class that implements \Interop\Amqp\AmqpConnectionFactory for example:
