1.沙箱环境
蚂蚁沙箱环境(Beta)是协助开发者进行接口功能开发及主要功能联调的辅助环境。沙箱环境模拟了开放平台部分产品的主要功能和主要逻辑。
在开发者应用上线审核前，开发者可以根据自身需求，先在沙箱环境中了解、组合和调试各种开放接口，进行开发调通工作，从而帮助开发者在应用上线审核完成后，能更快速、更顺利的进行线上调试和验收工作。
详细介绍---->点我点我
1.1配制沙箱环境
登录支付宝平台，点击自研开发者，点击导航的开发者中心-->研发服务，填写相关信息，完成实名认证
点击“开放平台-开发者中心-沙箱环境”。进入沙箱环境页面，系统已经自动为你创建一个应用，在基础信息中可以看到应用信息
点击查看应用公钥，设置应用公钥，点击查看秘钥生成方法
下载windows版RSA秘钥
下载该工具后，解压打开文件夹，运行“RSA签名验签工具.bat”（WINDOWS）------>采用默认的格式
使用2048位，.点击 “生成密钥”，点击“打开密钥文件路径”，即可找到生成的公私钥
生成的私钥需妥善保管，避免遗失，不要泄露。应用私钥需填写到代码中供签名时使用。应用公钥需提供给支付宝账号管理者上传到支付宝开放平台。
打开应用公钥2048.txt，将里面的内容复制一下进入到输入应用公钥的页面，输入公钥，点击保存。
2.SDK获取（software development kit）
中文名称软件开发工具，第三方服务商提供的实现软件铲平某项功能的工具包，一般以kpi和文档，范例的形式出现
这里注意的是，支付宝使用了rsa加密算法，这是支付宝独有的加密方式，我们使用了它的SDK之后，不要关心是如何加密的，只需要按照它的逻辑部署即可
获取连接------->点击此处
这里使用的是SDK封装好的一个python文件，需要安装pycryptodome,该文件是从GitHub上获取到的，为第三方提供，
目前支付宝已经提供了，如上，后期自行研究该SDK使用方法
pip3 install pycryptodome
pay.py代码 ---->后期需要部署到django中

3.项目部署
启动我们的django程序，创建相关的文件夹用于存放相关文件
## 需要说明的是，为了显示友好，我们需要把公钥和私钥名称进行修改，我这里改成了alipay_public_2048.txt和app_private_2048.txt
## 还有，对于公钥文件和私钥文件需要增加头部和尾部
公钥文件：
-----BEGIN PUBLIC KEY----- KEY... -----END PUBLIC KEY-----
私钥文件：
-----BEGIN RSA PRIVATE KEY----- KEY... -----END RSA PRIVATE KEY-----
django：
models.py --->自行启动添加数据
