- 支付宝支付核心需要的参数是(APPID，PRIVATE_KEY，ALIPAY_PUBLIC_KEY)
- APPID：创建应用后就有的APPID。
- PRIVATE_KEY：应用私钥
- ALIPAY_PUBLIC_KEY：支付宝公钥
- 上面的2，3的参数得自己弄到，参考文档：https://docs.open.alipay.com/291/105971/
- 下载好工具后所需要干的事情：（获取到的应用公钥配置到：蚂蚁金服开放平台中在 “应用信息” - “开发设置” - “加签方式”处点击 “设置应用公钥”。获取到的应用私钥就是：PRIVATE_KEY。支付宝公钥ALIPAY_PUBLIC_KEY：当设置应用公钥完成后就可以查看支付宝公钥内容。）
