我正在Windows中创建一个任务调度程序，只要保证在两个月后到期，就会发送一封电子邮件。运行Trying to get property of non-object之后我收到异常php artisan schedule:run这是我创建的命令SendEndRenewal.php
<?php
namespace App\Console\Commands;
use App\Device;
use App\Mail\EndRenewal;
use Carbon\Carbon;
use Illuminate\Support\Facades\Mail;
use Illuminate\Console\Command;
class SendEndRenewal extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'send:renewals';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Email ending renewals';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
$str = "";
$devices = Device::whereYear('endDate','=',Carbon::now()->year)->whereMonth('endDate','=',Carbon::now()->month+2)->get();
if (!empty($devices)) {
foreach ($devices as $device) {
Mail::to('vjztingson@gmail.com')->send(new EndRenewal($device));
$str .= "sent " . $device->name . " ";
}
}
$this->info($str);
}
}
这是我的电子邮件对象EndRenewal.php
<?php
namespace App\Mail;
use App\Device;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
class EndRenewal extends Mailable
{
use Queueable, SerializesModels;
public $device;
/**
* Create a new message instance.
*
* @return void
*/
public function __construct(Device $device)
{
$this->device = $device;
}
/**
* Build the message.
*
* @return $this
*/
public function build()
{
return $this->view('devices.show', ['device'=>$this->device]);
}
}
当我在build()中的EndRenewal.php中返回测试空白页时，它会起作用，但是当我传递一个对象并返回该对象的视图时它不起作用。我尝试了protected $device而不是公开它仍然没有用。请帮忙。谢谢！
我尝试了print_r它返回的传递对象
