Events 如何使用laravel 5.2中的事件队列？

我正在使用事件删除特定信息。 我有DeleteCourseConfirmation事件侦听器和DeleteBranchCourse事件

它很好用

以下是DeleteBranchCourse事件的代码

class DeleteBranchCourse extends Event{
use SerializesModels;

private $fee;
private $feeId;
public function __construct($fee,$feeId)
{
    $this->fee=$fee;
    $this->feeId=$feeId;

}

/**
 * Get the channels the event should be broadcast on.
 *
 * @return array
 */
public function broadcastOn()
{
    return [];
}
public function deleteCourse()
{
     $this->fee->destroy($this->feeId);
}}

以下是DeleteCourseConfirmation事件侦听器的代码

class DeleteCourseConfirmation{

public function __construct()
{

}

public function handle(DeleteBranchCourse $event)
{

    $event->deleteCourse();
}}

但是当我尝试php artisan queue:listen在DeleteCourseConfirmation中实现ShouldQueue接口后，将事件侦听器排队

class DeleteCourseConfirmation implements ShouldQueue{
use InteractsWithQueue;
public function __construct()
{

}

public function handle(DeleteBranchCourse $event)
{

    $event->deleteCourse();
}}

出现错误

没有模型[App\Modules\Branch\Models\Fee]的查询结果

我遵循Laravel 5.2文档排队事件侦听器

找到了解决方案

首先，我更改了事件火灾代码

Event::fire(new DeleteBranchCourse($fee,$feeId));

到

事件：：fire（新DeleteBranchCourse（$feeId））

因为我不需要将费用模型的对象发送给DeleteBranchCourse的构造函数

我把DeleteBranchCourse类改成这个

class DeleteBranchCourse extends Event{
use SerializesModels;

private $feeId;
public function __construct($feeId)
{
    $this->feeId=$feeId;
}

/**
 * Get the channels the event should be broadcast on.
 *
 * @return array
 */
public function broadcastOn()
{
    return [];
}
public function deleteCourse()
{
     Fee::destroy($this->feeId);
}}

public function handle(DeleteBranchCourse $event)
{

    $this->attempts($event->deleteCourse());
}}

最后从终端运行这个命令

php artisan queue:listen

或者将侦听器类的句柄函数更改为

class DeleteBranchCourse extends Event{
use SerializesModels;

private $feeId;
public function __construct($feeId)
{
    $this->feeId=$feeId;
}

/**
 * Get the channels the event should be broadcast on.
 *
 * @return array
 */
public function broadcastOn()
{
    return [];
}
public function deleteCourse()
{
     Fee::destroy($this->feeId);
}}

public function handle(DeleteBranchCourse $event)
{

    $this->attempts($event->deleteCourse());
}}

你的活动怎么样？请提供codeEvent:：fire（新DeleteBranchCourse（$fee，$feeId））；排队的数据存储在作业表中，但尝试次数为0次。当我运行php artisan queue:listen时，它尝试了多次，但没有得到模型[App\Modules\Branch\Models\Fee]错误的查询结果。您的事件引发情况如何？请提供codeEvent:：fire（新DeleteBranchCourse（$fee，$feeId））；排队的数据存储在作业表中，但尝试了0次。当我运行php artisan queue:listen时，它尝试了几次，但没有得到模型[App\Modules\Branch\Models\Fee]错误的查询结果
