在做线上、线下销售时,可以使用微信便捷支付,通过微信公众号收款有很多种收款方式,如下图:
今天我们来讲一下H5场景支付,使用手机浏览器打开就是H5方式,最常见的推广是短信内置链接,这种场景需要调用微信app,然后再启动微信支付及后续流程。
一、操作演示
随便用什么能扫码的app扫码下面二维码,打开后复制链接到手机浏览器打开页面。
二、微信支付配置
在本系列文章第18篇((2条消息) 实例:用C#.NET手把手教你做微信公众号开发(18)--使用微信支付给粉丝发红包_乱世刀疤的博客-CSDN博客)有介绍过,除了基础配置之外,以下配置是关键:

四、收款类源码
上面演示代码中用到的类和上一篇文章是同一个,源码已在上一篇文章中给出。
且用于收款记录存放的表也在上一篇文章给出,只是有一个字段标注的支付来源不同。
五、收款后收款记录状态更新
同上一篇文章介绍的内容一致,代码不再重复贴出。
