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jsapi支付，场景就是在微信内打开某个页面，完成在线支付，同样一个网页，使用微信打开就是jsapi方式，使用手机浏览器打开就是H5方式，我们下一篇讲H5方式。
一、操作演示
使用微信扫描下面图片，打开支付页面
在线收取1分钱，可以全流程感受
对CSDN的自动审核真的很无语，什么二维码都判定为违规图片，nnd，吐槽一下。
猿友们可以复制下面链接到微信对话框（如文件传输助手）后打开，即可体验支付全流程。

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：
三、jsapi演示源码
首先要通过oauth获取微信用户openid（源码在讲完支付的篇幅之后给出）。
前端页面源码如下：
