類工作中未發現有受保護的變量

Question

我試圖創建一個工作，但是當我設置行：

protected $param; 

從__construct通過數據處理（）我開始收到此錯誤：

Class not found 

當我刪除受保護的$參數;線，工作完美。但我無法獲取數據。我能做些什麼來解決這個問題？

<?php 

namespace App\Jobs; 

use App\Jobs\Job; 
use Illuminate\Queue\SerializesModels; 
use Illuminate\Queue\InteractsWithQueue; 
use Illuminate\Contracts\Queue\ShouldQueue; 

use App\Repositories\ProductRepository; 

class ImportProducts extends Job implements ShouldQueue 
{ 
    use InteractsWithQueue, SerializesModels; 

    protected $param; 


    /** 
    * Create a new job instance. 
    * 
    * @return void 
    */ 
    public function __construct($param) 
    { 
     $this->param = $param; 
    } 

    /** 
    * Execute the job. 
    * 
    * @return void 
    */ 
    public function handle() 
    { 
     //$products = $this->param['products']; 
     exit(); 

    } 
} 

這是整個錯誤消息：

Whoops, looks like something went wrong.

當作業使用SerializesModels特質預計在構造一個雄辯的模型。

您在構造函數和laravel中給出了與Eloquent Model不同的東西，該特性是SerializeModels特性的原因，它嘗試從$ param類重建Eloquent對象，但無法找到它。

嘗試從作業的特徵中刪除SerializesModels。
