在Magento 2.2上，我无法获得MagestyApps的答案。我需要添加一些其他文件。因为：
- 付款方式的购物车价格规则已从管理员中删除（如DaFunkyAlex所指出）；
- 在Magento 2.2并没有被应用在报价折扣，因为该方法
\Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address\PaymentMethod::generateFilterText（实际上它退到\Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address::generateFilterText），期待该数据payment_method要在引用地址设置;
- 即使将控制器从MagestyApps的答案更改为
payment_method在报价地址上设置数据，当报价成为订单时，也没有用，因为它不会持久payment_method；
以下模块为我解决了问题（感谢MagestyApps的回答，它基于此基础）：
