支付宝接口集成,本地环境调试支付请求
1.首先登录 蚂蚁金服网站，也就是支付宝开发者平台
登录蚂蚁金服开发者平台后，创建沙箱应用
也就是支付宝给开发者提供的调试环境应用
沙箱环境：https://openhome.alipay.com/platform/appDaily.htm?tab=info
2.我们设置应用公钥
设置公钥，访问https://docs.open.alipay.com/291/105971/ 这个网址
下载生成公钥的工具
下载解压后
生成公钥
公钥生成后会得到两个文件
生成公钥后，将公钥填写到信息配置里
当我们填好公钥保存后，会自动给我们生成支付宝公钥
将生成的支付宝公钥，复制下载到一个TXT文件中
将3个密钥修改成英文或者拼音名称后，放到项目中
在秘钥txt文件里，秘钥内容的头部和结尾加上两行字符串，注意所有秘钥都要加
-----BEGIN PRIVATE KEY-----
秘钥内容....
-----END PRIVATE KEY----

4.生成支付URL后，我们用这个URL模拟支付一下
注意：沙箱环境，支付的时候要用沙箱账号里提供的支付账号才可以支付
支付成功后已经，跳转到我们设置的同步处理页面
5.支付宝支付成功后通知接口验证
