我是 Magento 的新手，我正在 magento2.1 中实现自定义付款方式，但我完全迷路了。所需的信息流如下：
客户去结账并输入所有信息并转到付款方式，在那里他将选择我的自定义方式并按“下订单”按钮。
按下按钮后，我必须捕获订单信息、产品信息、数量、送货地址并添加其他信息，例如（'signature' - 用于验证的哈希、'urlResponse' 和 'urlConfirmation' 等），然后我需要在 Post 请求中将这些参数发送到 Gateway Provider URL。我不需要进行任何形式的验证，只需获取数据，添加更多并发送即可。
看完 Max Pronko 的教程

（由于缺少积分，我无法复制另一个链接，但在这个链接的末尾有对另一个链接的引用）。
我试图实现它，但我没有运气。据我了解，在按下“下订单”按钮后，请求被发送到一个捕获方法，我可以在其中执行必要的逻辑，然后创建一个 TransferObject 然后发送它（如何？）。
这是我的结构：
在供应商/PayU/etc/frontend/di.xml 我有：

我在实施正确的课程吗？我还需要什么其他文件？如果有人能指出我正确的方向，我将不胜感激。
