django中支付宝（沙箱）简单使用
python=3.6.8
django=2.1.8
python-alipay-sdk=2.0.1
非官方支付宝 Python SDK: https://github.com/fzlee/alipay/blob/master/README.zh-hans.md#alipay.trade.page.pay
沙箱环境配置
1、在支付宝开放平台---->开发者中心—>开发服务---->沙箱
2、RSA2密钥生成并上传
参考官方地址：https://opendocs.alipay.com/open/291/105971
新版的生成密钥工具为.exe文件，下载完成以后，请自行安装，安装好以后，桌面自动生成图标
运行支付宝开放平台开发助手
获取支付宝公钥
django中使用alipay
alipay公钥和app私钥在django中存放行式
alipay公钥
app私钥
