支付宝当面付官方Demo调试

配置沙箱环境

官方文档

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。

  1. 生成并上传RSA2(SHA256)的应用公钥，详见生成RSA密钥；配置RSA2(SHA256)的应用公钥后，不需要配置RSA(SHA1)密钥，RSA和RSA2签名算法区别可以参考此处；

  2. 编写代码时，请将

​ a.请求网关修改为：https://openapi.alipaydev.com/gateway.do

​ b.appid切换为沙箱的appid

​ c.签名方式使用RSA2

​ d.应用私钥使用第1步生成的RSA2(SHA256)的私钥(请根据开发语言进行选择原始或pkcs8格式)

​ e.支付宝公钥切换为第1步配置后应用公钥后，点击查看支付宝公钥看到的公钥

当面付demo演示

  1. 下载demo，地址：https://docs.open.alipay.com/194/105201/

  2. 将demo导入idea

可以用二维码生成器将返回的qr_code生成，用支付宝沙箱版进行扫码支付测试

至此，支付宝当面付的官方demo就调通了，可以进行后续开发
