我想使用事件和监听器在laravel 5.5中发送电子邮件。但是当在控制器上调用Event时，我收到了此错误消息。
类型错误：传递给App \ Events \ EMailNotif \ UserWorkflowEmail :: __ construct（）的参数1必须是App \ Events \ EMailNotif \ App \ WFApprover的实例，给定的Illuminate \ Support \ Collection实例，在C中调用：第289行\ wamp64 \ www \ B2BSite \ app \ Http \ Controllers \ OrdersController.php
我在网上搜索，但无法找到解决方案。我希望我能在这个论坛找到解决方案。请帮助。
这是我的控制器

/**
* Create a new event instance.
*
* @return void
*/
public function __construct(App\WFApprover $wf_apprv)
{
$this->wf_apprv = $wf_apprv;
}
}
这是我的倾听者
<?php
namespace App\Listeners\EmailNotif;
use App\Events\EmailNotif\UserWorkflowEmail;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendWorkflowEmail
{
/**
* Create the event listener.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* @param UserWorkflowEmail $event
* @return void
*/
public function handle(UserWorkflowEmail $event)
{
dd($event);
}
}
答案 0 :(得分：0)
我在EventServiceProvider中使用它：
protected $listen = [
'App\Events\Signature\*' => [
HandleSignature::class
],
];
原来我不得不：
protected $listen = [
InitiatedSuccessfully::class => [
HandleSignature::class
],
SignedSuccessfully::class => [
HandleSignature::class
],
];
不知道为什么。我从Laravel 5.3升级到5.5并浪费了一个多小时。
