    目录

    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）

    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

    支付宝开发地址

    支付宝开放平台： https://open.alipay.com/platform/home.htm
支付宝沙箱环境： https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付宝开发者文档：https://openhome.alipay.com/developmentDocument.htm
电脑网站支付流程：https://docs.open.alipay.com/270
生成签名：https://docs.open.alipay.com/291/106103/
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()

    # -*- coding: utf-8 -*-
