       wemall-mobile是基于WeMall的Android app商城,只需要在原商城目录下上传接口文件即可完成服务端的配置,客户端可定制修改。本文分享Native(原生)支付模式一demo,供技术员参考学习。

 

wemall官网地址:http://www.wemallshop.com

 

模式一:商户按固定格式生成链接二维码,用户扫码后调微信

 * 会将productid和用户openid发送到商户设置的链接上,商户收到

 * 请求生成订单,调用统一支付接口下单提交到微信,微信会返回

 * 给商户prepayid。

 * 本例程对应的二维码由native_call_qrcode.php生成;

 * 本例程对应的响应服务为native_call.php;

 

 * 需要两者配合使用。

 

native_call.php
