记录一次用python升级微信支付的代金券的接口

本文主要是介绍记录一次用python升级微信支付的代金券的接口，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

最近打开微信支付的后台，做代金券页面竟然要升级接口

官方给了一堆文档，一如既往读的头疼

于是微信开发者社区看到一篇文章

借鉴一下，来这里mark一下

首先你要先安装python不会的话去参照这个链接安装一下

https://www.liaoxuefeng.com/wiki/1016959663602400/1016959856222624

我就是参照这个安装的，安装的3.x版本

安装成功后看一下版本

出现这个就是安装成功

然后接下来打开微信支付的后台

提前准备好

1.微信支付商户号

2.api秘钥

好了接下来

准备开始

随便新建一个.py的文件，在这里我是命名为1.py

接下来随便用个编辑器打开，我这里用的hubider你用vscdoe都行，用记事本都ok

复制的微信社区一个大佬的代码

复制之前先替换一下里面对应内容

然后再这个文件夹下打开cmd

python 1.py运行
