    if verify_re is True:

        trade_no = processed_dict.get('trade_no', None)#支付宝交易号
        trade_status = processed_dict.get('trade_status', None)#交易状态

        existed_orders = OrderInfo.objects.filter(order_sn=order_sn)
        for existed_order in existed_orders:
            existed_order.pay_status = trade_status  #更新交易状态
            existed_order.trade_no = trade_no
            existed_order.pay_time = datetime.now()
            existed_order.save()

        response = redirect("index")
        response.set_cookie("nextPath","pay", max_age=2)
        return response
    else:
        response = redirect("index")
        return response

老师，请问get请求中是不是并没有trade_status，我们的trade_status更新是依赖异步的POST请求，进行的更新？
