前言

该支付就是调用他们的支付页面，绑卡无需我们操作，所有支付操作都有他们控制。对接的支付是，一键快捷支付，参考的文档是他们的demo，这个官方的demo不是springboot项目不是idea，需要自己配置tomcat运行。该篇文章中所涉及的代码，是本人自己根据官方demo以及GitHub上的开源项目所自己写的。

对接杉德的一键快捷支付

官方文档

杉德的商家中心

问题

根据文档上的调用接口，苹果端、postman测试工具均无法跳转到杉德的官网支付页面
解决：服务端做个跳转页面，让安卓、ios端调用自身浏览器访问

测试只能通过静态页面（demo里有）发送（从后端拿到sign和data封装的数据）
