python支付宝自动支付_python支付宝支付流程

1.项目展示&＃xff1a;

2.扫码支付

3.支付完成

4.跳转成功

一、注册账号

https://openhome.alipay.com/platform/appDaily.htm?tab&＃61;info

二、设置应用公钥

私钥需要复制到程序里的&＃xff1a;

程序里面阿里的公钥在这里获取&＃xff1a;

、

这里放的是阿里的公钥。

代码实现&＃xff1a;

代码结构&＃xff1a;

1. 首先是&＃xff1a;更改程序里面的阿里公钥和用户私钥以及app_id

2.pay.py 这是从git上找到的支付宝支付接口(PC端支付接口)

3、

urlpatterns&＃61;[

url(r&＃39;^admin/&＃39;, admin.site.urls),

url(r&＃39;^page1/&＃39;, views.page1),

6.模板

注意&＃xff1a;安装Crypto

把安装包放到C:\Users\frank\AppData\Local\Programs\Python\Python36\Lib\site-packages   然后解压缩就行了。
