python微信开发入门篇JSSDK含微信支付(二)

本节完成微信js sdk + 微信支付调用,项目基础部分请参照入门篇第一章:https://www.cnblogs.com/wangcongxing/p/11546780.html

  1.微信服务号设置

　　   登录服务号后台设置如下:

　　　1.登录地址:https://mp.weixin.qq.com/

　　　2.设置-->公众号设置-->功能设置

  2.微信商户后台设置

　　　1.登录地址(因为需要安装exe插件, 设置浏览为兼容模式  建议使用QQ浏览器):https://pay.weixin.qq.com  

　　　2.账户中心-->账户设置-->API安全

　　　3.产品中心-->开发配置  设置支付授权目录

　　　　3.产品中心-->APPID授权管理 

支付效果:

  4.案例源码

　　　案例目录结构如下
