支付宝支付功能
登录支付宝官网开发平台
下载SDK，
支付宝并没有python版本SDK
SDK有实例和代码。
没有python则自己写，或者去github找。
本次利用alipay这个组件。
先安装一个pycrytodome
pip3 install pycrytodome
如果真实环境，按上面这个来注册。
测试环境需要用沙箱环境。
向支付宝提交的这个链接，在测试模式有dev,生产环境删掉dev
公钥复制到支付宝里，私钥存到自己django文件中，自己文件的公钥是来自支付宝的公钥。
上面沙箱环境不需要配置。
下面是创建一个生产环境的应用。
以下为支持的功能
以上为真实生产需要的操作。
然后之后看pay项目代码。
以上为目录结构。
views.py：
1 from django.shortcuts import render, redirect, HttpResponse

10 # 服务器异步通知页面路径 需http: // 格式的完整路径，不能加?id = 123 这类自定义参数，必须外网可以正常访问
11 # 发post请求
12 notify_url = "http://www.xxxx.com:8009/page2/" #将这两个链接复制到支付宝中
13
14 # 页面跳转同步通知页面路径 需http: // 格式的完整路径，不能加?id = 123 这类自定义参数，必须外网可以正常访问
15 # 发get请求
16 return_url = "http://www.xxxx.com:8009/page2/"

18 merchant_private_key_path = "keys/pri" #设置公钥和私钥的地址，文件上下两行begin和end是必须的，公钥就放在第二行。

如果需要测试，需要用公网可以直接访问的url，
我们可以通过自己单机测试，更改本机hosts文件，将本机ip和views里return_url一致。
更改C:\Windows\System32\drivers\etc\hosts
最后从支付宝下载对应的沙河手机app，充值之后就可以付款了，快去尝试吧。
