十二、支付宝沙箱环境配置
12.1.创建应用
进入蚂蚁金服开放平台（https://open.alipay.com/platform/home.htm），登录后进入管理中心-->>应用列表
创建应用
创建应用后会有一个appid。还需要提交信息进行审核。微信支付和支付宝支付都是要求企业认证才可以完成的，个人开发不可以，所以我们需要用
沙箱环境，它可以让我们不具备这些应用或者说应用审核还没通过的时候先开发调试
12.2.沙箱环境
沙箱应用地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info
（1）公钥和私钥的生成方法
地址：https://docs.open.alipay.com/291/105971/
选winwods，如果linux就选linux
下载好工具照着生成就可以了
（2） 把生成的公钥和私钥拷贝到trade/keys下面--->>>重命名--->>首位各添加下面的内容
-----BEGIN PRIVATE KEY----- -----END PRIVATE KEY-----
（3）把支付宝公钥也拷贝到这路径下面，同样首尾添加
12.3.文档说明
我们主要用到电脑网站支付，文档地址：https://docs.open.alipay.com/270
用到的API接口：统一收单下单并支付页面接口
里面有文档说明
几个比较重要的参数
sign签名
应该看未使用开放平台的SDK里面的说明：https://docs.open.alipay.com/291/106118
请求参数
必填的几个：
12.4.编写代码
把环境改成本地的
首先的安装一个模块
pip install pycryptodome
utils中新建alipay.py，代码如下：

运行alipay.py,会生成一个支付链接url，点进去跳到支付页面
点“登录账户付款”，用沙箱账号付款
输入账号密码以及支付密码，成功付款
12.5.django集成支付宝notify_url和return_url
（1）配置url
# 配置支付宝支付相关接口的url path('alipay/return/', AlipayView.as_view())
（2）alipay.py
把return_url和notify_url都改成远程服务器的地址
return_url="http://47.93.198.159:8000/alipay/return/" app_notify_url="http://47.93.198.159:8000/alipay/return/"
