Array to string conversion error in Laravel
提问by sesc360
I want to use the Queue in Laravel to push messages to a Queue. Therefore I wanted to try out the basic flow first, which throws errors at the moment.
我想使用 Laravel 中的队列将消息推送到队列。因此，我想先尝试一下基本流程，但目前它会引发错误。
As I am using the CommandBus in Laravel, I created A listener:
当我在 Laravel 中使用 CommandBus 时，我创建了一个侦听器：
Listener - IncidentNotifier.php
监听器 - IncidentNotifier.php
<?php
namespace App\Listeners;
use App\Events\Incident\IncidentWasPosted;
use App\Events\EventListener;
use App\Http\Traits\SearchResponder;
use App\Jobs\SendAlarmToResponder;
use Illuminate\Foundation\Bus\DispatchesJobs;
class IncidentNotifier extends EventListener {
use DispatchesJobs, SearchResponder;
public function whenIncidentWasPosted(IncidentWasPosted $event) {
$responders = $this->getResponderInRange($event);
$this->dispatch(new SendAlarmToResponder($responders));
}
}
This listener should queue a job (not yet done) to use the push notification service as this would block my system at the moment without using Queues.
此侦听器应将作业（尚未完成）排队以使用推送通知服务，因为这会在不使用队列的情况下阻塞我的系统。
Job - SendToAlarmResponder.php
工作 - SendToAlarmResponder.php
<?php
namespace App\Jobs;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendAlarmToResponder extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue, SerializesModels;
protected $responders = array();
public function __construct($responders)
{
$this->$responders = $responders;
}
public function handle($responders)
{
var_dump($responders);
}
}
searchResponder method
searchResponder 方法
public function getResponderInRange($event) {
$position[] = array();
$position['latitude'] = $event->incident->latitude;
$position['longitude'] = $event->incident->longitude;
$queryResult = ResponderHelper::searchResponder($position);
return $queryResult;
}
The responders array is the variable I would like to pass over to the job to be handled there later on. This is an array of objects I received from my Database and works well. But I get the error message:
响应者数组是我想传递给稍后在那里处理的工作的变量。这是我从我的数据库收到的一组对象并且运行良好。但我收到错误消息：
ErrorException in SendAlarmToResponder.php line 19:
Array to string conversion
How can I hand over this array to the job?
我怎样才能把这个数组交给工作？

This
这个
$this->$responders = $responders;
should be:
应该：
$this->responders = $responders;
with no $sign after ->
$之后没有任何迹象->

In your Job - SendToAlarmResponder.php
在您的工作中 - SendToAlarmResponder.php
<?php
namespace App\Jobs;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendAlarmToResponder extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue, SerializesModels;
protected $responders = array();
public function __construct($responders)
{
$this->$responders = $responders;
}
public function handle($responders)
{
var_dump($responders);
}
}
Change it this -
改成这个——
public function __construct($responders)
{
$this->$responders = $responders;
}
to --
到 -
public function __construct($responders)
{
$this->responders = $responders; // here is the line that you need to change
}
Thanks. Same error i got and it work.
谢谢。我遇到了同样的错误，它可以工作。
