实现方法

实现流程

  1. 用户在电脑桌面端的浏览器中发起微信支付
  2. 商户系统调用 OTT Pay API 进行支付，OTT Pay 服务器返回 支付链接
  3. 商户系统前端页面根据 支付链接 生成 支付二维码，并在电脑桌面端浏览器中显示
  4. 用户用微信扫描 支付二维码 会调起微信钱包进行支付
  5. 应用程序通过 查询支付状态 API 获得支付结果

data.put("amount", 1);
data.put("callbackURL", "https://your.callback.url");
data.put("remark", "this is remark");
