队列如何判断任务是成功还是失败了

照你的意思是，当走了代码：throw new xxx

class NotifyFailGetOrder implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
    protected $notify_url='';
    protected $data=[];
    protected $token='';
    public $tries = 4;
    public $backoff = 10;
    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($notify_url,$data,$token)
    {
        //
        $this->notify_url = $notify_url;
        $this->data = $data;
        $this->token = $token;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $notify_url = $this->notify_url;
        $data = $this->data;
        $token = $this->token;
        try{
                $result = send_notify_url($notify_url,$data,$token);//请求下游
                if($result != 'success'){
                    //走这里完成代码
                }else{
                    //走这里重试
                    throw new \Exception (' 回调异常！'); 
                }

        }catch(\Exception $e){
         //走这里重试
            throw new \Exception($e);
        }
    }
}

就是手动将该次队列失败，如果没到达限制次数或仅一次，就会再次重试，如果没有throw new的异常抛出，该队列就是成功的对么
