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

<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 com.alipay.api.domain.AlipayTradeAppPayModel; import com.alipay.api.internal.util.AlipaySignature; import com.alipay.api.request.AlipayTradeAppPayRequest; import com.alipay.api.response.AlipayTradeAppPayResponse; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.servlet.http.HttpServletRequest; import java.util.HashMap; import java.util.Iterator; import java.util.Map; @RestController @RequestMapping("/pay/ali") public class AliPayController{ /** * 沙箱应用APP_ID应用id */ public final static String APP_ID="2021000118695484"; /** * 应用私匙 */ public final static String APP_PRIVATE_KEY="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"; /** * 编码 */ public final static String CHARSET="UTF-8"; /** * 支付宝公钥 */ public final static String ALIPAY_PUBLIC_KEY="MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAp09reAC0u4oUuvcptaWSqLw6YMUHyIKW7i1pW+4bsYHHivDK2yEIGozfbYA+AB14V3gRPwPd2IEmTUGBGL2KdITMGy65kF0O53cN8Soyi8z0zjn/A0pvQ/aexrJJP1w0IXKsG1xXa6ckS9JDtD5aaUNc829igMhrXPs8LQUN0lsmSwgUqaOzkIXwncHEEf1hiU/9UPaA7S7IOZ8wSQazXMkMRkWeCLMfvGNzTDpKRGoZdKCtfv6/7kLHGl9rfGX8HTDRj479bieiCgxeeXv4MC7HFAwx/TRZbOUeQTri/GbqWZ7oXQLp/T2/QROKN1J3tCKZSRi/Z9lZrlNjWgk3+QIDAQAB"; /** * 签名类型 */ public final static String STRING="RSA2"; /** * 沙箱网关 */ public final static String GAIEWAY_URL="https://openapi.alipaydev.com/gateway.do"; public final static String FORMT="json"; /** * 获取订单信息 * @param orderId * @return */ @GetMapping("/getOrderInfo") public String showOrderInfo(String orderId){ //实例化客户端 AlipayClient alipayClient = new DefaultAlipayClient(GAIEWAY_URL, APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2"); //实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest(); //SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。 AlipayTradeAppPayModel model = new AlipayTradeAppPayModel(); model.setBody("我是测试数据"); model.setSubject("大白兔奶糖"); model.setOutTradeNo("3号"); model.setTimeoutExpress("30m"); model.setTotalAmount("10000"); model.setProductCode("QUICK_MSECURITY_PAY"); request.setBizModel(model); //异步回调的地址 request.setNotifyUrl("http://3v3n846184.qicp.vip/pay/ali/notity_url"); try { //这里和普通的接口调用不同，使用的是sdkExecute AlipayTradeAppPayResponse response = alipayClient.sdkExecute(request); System.out.println(response.getBody());//就是orderString 可以直接给客户端请求，无需再做处理。 } catch (AlipayApiException e) { e.printStackTrace(); } return null; } @RequestMapping("/notity_url") public String notify_url(HttpServletRequest request){ //获取支付宝POST过来反馈信息 Map<String,String> params = new HashMap<String,String>(); Map requestParams = request.getParameterMap(); for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) { String name = (String) iter.next(); String[] values = (String[]) requestParams.get(name); String valueStr = ""; for (int i = 0; i < values.length; i++) { valueStr = (i == values.length - 1) ?

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
