支付宝支付

支付宝开发分为生产环境和沙箱环境，沙箱环境是用来做测试用的

1：使用支付宝沙箱环境，会自动生成APPID,商户UID,支付宝网关为https://openapi.alipaydev.com/gateway.do。项目正式上线时网关为https://openapi.alipay.com/gateway.do

 

2：需要我们为项目添加应用公钥（由平台提供的秘钥工具生成，一般用RSA2，2048位），支付宝公钥由支付宝提供。主要用来加密和解密。

2.1：私钥加密，公钥解密，2.2：私钥签名，公钥延签

2.1.1 加密用公钥，解密用私钥

2.2.1：接收支付宝返回的数据需通过支付宝公钥进行验签，确认返回数据者身份为支付宝。  

2.2.2：客户端将商户的签名字符串用私钥签名上传到服务器，服务器端通过开发人员上传的（应用）公钥进行验签，确认身份。

商户后台需要传入支付宝公钥，对支付宝返回数据进行延签。

商户后台需要传入应用私钥，对数据进行加密。

公共平台有支付宝公钥，商户应用公钥。双方都可以获取。

支付宝后台获取应用公钥对商户数据进行延签和解密。

同样商户后台获取支付宝公钥，对返回数据进行延签和解密。

支付宝生成秘钥时，需要在公共平台验签，

 

 3：验证秘钥正确性，下载签名工具对秘钥进行验证

      

4：将与应用公钥对应的应用私钥，放到验签工具的左方框内，生成右边的签名。 

 

 5：将生成的签名放入到验签框内。

     验证，提示成功，保存

  

6：为应用添加应用网关和授权回调地址

应用网关为商户的服务器

授权回调地址需要公网能访问，商户后台需要对其拦截并验证。是否付款成功等。

7：网页应用创建成功。

 我们就可以编写商户后台程序，为支付宝准备相应的数据，进行支付。  https://github.com/egzosn/pay-java-parent

 

 8:后台对对接支付宝进行配置
