支付宝支付讲解

1：首先你先下载好自己的软件
支付宝开放平台

2去支付宝开放平台申请自己的沙箱环境
3下载花生壳，内网穿透

4手机安装客户端调试工具

接下来去申请自己的沙箱环境
1首先进入到支付宝官方网页

2，入驻登入一下

3登入进来后选择这个

4进入到这后就差不多了

5打开你的支付宝开放平台开发助手生成私钥和公钥、

6复制公钥到这里生成应用公钥



现在环境基本上搭好了，现在去操作一波
引入pom依赖

            System.out.println(response.getBody());//就是orderString 可以直接给客户端请求，无需再做处理。

    public static void main(String[] args) {
        AliPayController aliPayController = new AliPayController();
        aliPayController.getOrderInfo();
    }


}

接下来你按照上面的修改就是了

私钥就是你开放平台助手生成的
公钥就是你在沙箱环境哪里生成的

将控制台生成的这串代码复制下来

代码放到你的小冰棒也就是你的客户端调试工具上

你的账号密码是这个

然后支付就行了
在你的沙箱支付宝可以看到详情


因为本人初学没多久，因此暂时只能搞这么简单的，觉得不过瘾的可以去看一下大神的
