支付宝支付功能的实现

支付宝支付功能实现

一.环境准备

二.配置沙箱环境

1.浏览器搜索 支付宝开放平台

2.找到开发服务，选择沙箱

3.根据文档提示，一步步配置

4.配置完成后的样子

5.下载好支付宝手机开放平台助手，可以获取应用私钥

**注意：**应用公钥不是直接获取下那个，它是先复制应用公钥是，再到沙箱环境中获取

首先进入沙箱

把你从支付宝开发平台开发助手上复制的 应用公钥，粘贴上去

最后保存设置，就会出现这个界面，得到的就是，我们想要的公钥，是不是很简单呢

三，代码部分

1.新建项目，我用的是SpringBoot项目

导入支付需要的依赖

   <!-- https://mvnrepository.com/artifact/com.alipay.sdk/alipay-sdk-java -->
        <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>3.7.110.ALL</version>
        </dependency>

2.编写控制器AlipayController

package com.ytzl.trade2020828.controller;
import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;

import java.util.Iterator;
import java.util.Map;
@RestController

}

3.测试，手机上下载 客户端调试工具

1.下载手机客户端

2.将服务器签名好的字符串复制进去

这样支付成功啦，是不是神奇呢
