我有一个用Laravel编写的遗留API,我正在尝试从RabbitMQ队列发布数据。我正在使用第三方库将RabbitMQ集成到本机Laravel Queue架构中。哪个工作正常,并且在侦听器控制台命令运行时正确处理消息。
但是,当我传递以下事件时,包括队列处理程序所需的作业和数据键......
{"job":"SixtyFiveContrib\\Jobs\\CreateSubmissionMetaDataJob@handle","data":{"title":"","story":"Testing 123","author":"Ewan Valentine","email":"","address":"","dob":"","phone":"","site":"The Lad Bible","legal":"The LAD bible - Facebook","agreed":false,"signature":"","files":[{"filename":"test.png","filesize":0,"filetype":""}],"agreement":{"id":"","facebook_id":""},"attempts":1036}}
我注意到处理排队事件的类,拆分类路径和方法名称(SixtyFiveContrib \ Jobs \ CreateSubmissionMetaDataJob和handle),并尝试从容器中调用该类。
但是,作业不会自动成为容器的一部分。当我尝试将作业自己添加到容器中时,我遇到了无法将队列中的“数据”动态传递到作业中的情况,例如......
$this->app->bind(\SixtyFiveContrib\Jobs\CreateSubmissionMetaDataJob::class, function() {
return \SixtyFiveContrib\Jobs\CreateSubmissionMetaDataJob(????);
});
如果我从容器中省略此条目,则队列处理程序无法再解析作业,我收到以下错误...
[照亮\合同\容器\ BindingResolutionException]
中
无法解析的依赖项解析[参数#0 [$ data]] 在类SixtyFiveContrib \ Jobs \ CreateSubmissionMetaDataJob
这是我的工作类(省略敏感业务逻辑)。
<?php
namespace SixtyFiveContrib\Jobs;
use App;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldQueue;
use SixtyFiveContrib\Jobs\Job;
/**

*/
class CreateSubmissionMetaDataJob extends Job implements SelfHandling
{
use InteractsWithQueue, SerializesModels;
/**
* @var array $data
*/
public $data;
/**
* __construct
*
* @param array $this->data
*/
public function __construct($data)
{
$this->data = $data;
}
public function handle()
{
try {
// Omitted
} catch (\Exception $e) {
\Log::error($e->getMessage() . " " . $e->getLine());
return $e->getMessage();
}
}
}
答案 0 :(得分:1)
好的,我明白了!您必须将数据作为第二个参数传递给handle
或fire
方法,第一个参数是应用程序实例。
