django支付宝支付
新建支付宝应用
# 访问"支付宝开发平台"登录，可以访问开发者中心
https://open.alipay.com/platform/home.htm
# 可以参考"电脑网站支付" 熟悉电脑支付整体流程
https://docs.open.alipay.com/270/105899/
创建应用（使用沙箱环境测试）
- 沙箱环境说明
- 线上环境需要创建应用，因为我们不是企业，没有资质，所以只能申请沙箱环境
- 简单来讲沙箱环境就是给开发者使用的测试环境
- 沙箱环境地址： https://openhome.alipay.com/platform/appDaily.htm?tab=info
按照官方要求生成私钥（可以上支付宝开发平台下载支付宝开发助手）
把生成的app公钥粘贴到沙箱的app中
沙箱环境地址： https://openhome.alipay.com/platform/appDaily.htm?tab=info
查看沙箱账号和密码

python-alipay-adk : https://github.com/fzlee/alipay/blob/master/README.zh-hans.md
说明
- 阿里官方没有提供python对接支付的sdk，但是python库中有非官方的sdk包可以使用
- python-alipay-adk : https://github.com/fzlee/alipay/blob/master/README.zh-hans.md
- 使用起来非常简单，只要传入几个必要的参数就可以完成
- 由于支付对安全要求很高，所以要理解对接支付宝安全的流程： 公钥加密、私钥解密 这八个字
在utils中封装请求支付宝扫码地址url的函数和生成订单id的函数
私钥和公钥可以放在app_private_key.pem 和 alipay_public_key.pem文件中。使用时引入
沙箱环境中 app 私钥
private_key_string= open('app_private_key.pem').read()
支付宝公钥
public_key_string = open( 'alipay_public_key.pem').read()
