前言:最近开发支付宝支付功能,总结一下做个分享
官方文档:https://opendocs.alipay.com/apis
支付宝沙箱地址: https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付宝支付流程:
准备工作:获取支付宝沙箱数据(appid,支付宝网关,rsa2秘,沙箱支付账号等)
集成springboot,使用java代码发起支付请求
支付宝收到支付请求后,返回html代码片段,用于前端展示二维码
扫码支付成功后,支付宝发送同步、异步通知请求,同步、异步通知路径可在配置文件中进行配置
收到异步通知结果后,进行验签,验签通过,返回成功信息通知支付宝不在进行异步通知
此时支付宝支付流程完成,调用支付宝查询接口,确认支付成功
一、获取支付宝沙箱数据
打开上述沙箱地址,获取沙箱配置,查看下图信息
二、集成springboot,使用java代码发起支付请求
1、在pom.xml文件添加支付宝依赖

<!-- 支付宝支付 --> <dependency> <groupid>com.alipay.sdk</groupid> <artifactid>alipay-sdk-java</artifactid> <version> 3.7 . 26 .all</version> </dependency> |
2、在项目中新建一个支付宝工具类
