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

开发者平台

也就是支付宝给开发者提供的调试环境应用

沙箱测试应用

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

生成密钥

下载解压后

签名工具

生成公钥

生成公钥

公钥生成后会得到两个文件

公钥文件

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----

密钥配置

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
