* @author zhangye

* @version 1.0

* @description 扫码⽀付接⼝

* @date 2019/12/19

* <p>

* ⽀付接⼝官⽅⽂档地址:pay.weixin.qq/wiki/doc/api/native.php?chapter=6_5 * 本 demo 使⽤的⽀付⽅式为: 模式⼆

* <p>

* 扫码⽀付流程说明:

* 1.需要商户⽣成订单

* 2.商户调⽤统⼀下单接⼝获取⼆维码链接 code_url (请求参数请见官⽅⽂档)

* 请求参数中的 notify_url 为⽤户⽀付成功后, 服务端回调商户的接⼝地址

* 3.商户根据 code_url ⽣成⼆维码

* 4.⽤户使⽤扫码进⾏⽀付

* 5.⽀付成功后, 服务端会调⽤ notify_url 通知商户⽀付结果

* 6.商户接到通知后, 执⾏业务操作(修改订单状态等)并告知服务端接收通知成功

* <p>

* 查询⽀付订单、关闭⽀付订单流程较为简单，请⾃⾏查阅官⽅⽂档
