/**
 * 富友 支付 通知实现
 * 说明：信息通过 http 或 https 形式 post 请求递交给前置系统，编码必须为 UTF-8
 * Json 格式参数名：如下表
 * 参数值：如下表
 * 测试地址：商户提供
 * 生产地址：待定
 * <p>
 * 如图中第 6 步中异步回调，下单(主扫)交易的结果是以异步的形式进行回调的。富友在接受到支付宝等支付通道的回调结果以
 * 后再回调商户。商户接收回调成功处理成功后返回字符串”1” , 后富友停止回调给商户。最多回调 5 次，每次间隔 30S。
 * （重要~重要~重要：不保证通知最终一定能成功，在订单状态不明或者没有收到微信，支付结果通知的情况下，
 * 建议商户主动调用【2.3 订单查询】确认订单状态）
 * 只有主扫、公众号/服务窗支付会通过此接口发异步通知，条码支付没有异步通知。
