支付宝沙箱环境配置

进入支付宝的开放平台——沙箱支付

沙箱环境

进入个人沙箱环境

点击进入沙箱环境并用支付宝登陆

沙箱管理界面如图所示：

appid，支付宝网关，自定义密钥等

沙箱账号界面如图所示：

这里是用来支付的账号和密码

密钥的生成

密钥工具下载

这时我们拿到两个密钥，将它们保存，这两个密钥很重要

应用私钥

应用公钥

拿到两个密钥后，进行自定义密钥配置

进入最开始的沙箱管理界面，点击自定义密钥，点击设置并查看，我们选择的是公钥模式

在这里将上一步骤生成的应用公钥填进来

得到支付宝公钥这另一个密钥，记住并保存这个支付宝公钥

至此，我们沙箱环境的配置和基本参数都已经获取到。

spring boot 环境配置

导入支付宝支付的依赖到pom.xml中

        
            com.alipay.sdk
            alipay-easysdk
            2.2.0
        
        
        
            com.alipay.sdk
            alipay-sdk-java
            4.34.0.ALL

在 application.yml 里面进行配置

alipay:
  appId: 
  appPrivateKey: 
  alipayPublicKey: 
  notifyUrl:

alipay的java配置：AplipayConfig.java

package com.kp.config;
import com.alipay.easysdk.factory.Factory;
import com.alipay.easysdk.kernel.Config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
@Data
@Component
//读取yml文件中alipay 开头的配置
@ConfigurationProperties(prefix = "alipay")
public class AliPayConfig {
    private String appId;
    private String appPrivateKey;
    private String alipayPublicKey;
    private String notifyUrl;
    @PostConstruct
    public void init() {
        // 设置参数（全局只需设置一次）
        Config config = new Config();
        config.protocol = "https";
        config.gatewayHost = "openapi.alipaydev.com";
        config.signType = "RSA2";
        config.appId = this.appId;
        config.merchantPrivateKey = this.appPrivateKey;
        config.alipayPublicKey = this.alipayPublicKey;
        config.notifyUrl = this.notifyUrl;
        Factory.setOptions(config);
        System.out.println("=======支付宝SDK初始化成功=======");
    }
}

支付接口

新建一个 AliPayController.java

package com.kp.controller;
import com.alipay.easysdk.factory.Factory;
import com.kp.config.AliPayConfig;
import com.kp.entity.AliPay;
import com.kp.entity.Orders;
import com.kp.mapper.OrderMapper;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.request.AlipayTradePagePayRequest;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;
@RestController
@RequestMapping("alipay")
@Transactional(rollbackFor = Exception.class)
public class AliPayController {
    @Resource
    AliPayConfig aliPayConfig;
    @Resource
    private OrderMapper shopOrderMapper;
    private static final String GATEWAY_URL ="https://openapi-sandbox.dl.alipaydev.com/gateway.do";
    private static final String FORMAT ="JSON";
    private static final String CHARSET ="utf-8";
    private static final String SIGN_TYPE ="RSA2";
    @GetMapping("/pay") // &subject=xxx&traceNo=xxx&totalAmount=xxx
    public void pay(AliPay aliPay, HttpServletResponse httpResponse) throws Exception {
        AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL, aliPayConfig.getAppId(),
                aliPayConfig.getAppPrivateKey(), FORMAT, CHARSET, aliPayConfig.getAlipayPublicKey(), SIGN_TYPE);
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        request.setNotifyUrl(aliPayConfig.getNotifyUrl());
        request.setBizContent("{\"out_trade_no\":\"" + aliPay.getTraceNo() + "\","
                + "\"total_amount\":\"" + aliPay.getTotalAmount() + "\","
                + "\"subject\":\"" + aliPay.getSubject() + "\","
                + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
        String form = "";
        try {
            // 调用SDK生成表单
            form = alipayClient.pageExecute(request).getBody();
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        httpResponse.setContentType("text/html;charset=" + CHARSET);
        // 直接将完整的表单html输出到页面
        httpResponse.getWriter().write(form);
        httpResponse.getWriter().flush();
        httpResponse.getWriter().close();
    }
    @PostMapping("/notify")  // 注意这里必须是POST接口
    public String payNotify(HttpServletRequest request) throws Exception {
        if (request.getParameter("trade_status").equals("TRADE_SUCCESS")) {
            System.out.println("=========支付宝异步回调========");
            Map params = new HashMap();
            Map requestParams = request.getParameterMap();
            for (String name : requestParams.keySet()) {
                params.put(name, request.getParameter(name));
                // System.out.println(name + " = " + request.getParameter(name));
            }
            String tradeNo = params.get("out_trade_no");
            String gmtPayment = params.get("gmt_payment");
            String alipayTradeNo = params.get("trade_no");
            // 支付宝验签
            if (Factory.Payment.Common().verifyNotify(params)) {
                // 验签通过
                System.out.println("交易名称: " + params.get("subject"));
                System.out.println("交易状态: " + params.get("trade_status"));
                System.out.println("支付宝交易凭证号: " + params.get("trade_no"));
                System.out.println("商户订单号: " + params.get("out_trade_no"));
                System.out.println("交易金额: " + params.get("total_amount"));
                System.out.println("买家在支付宝唯一id: " + params.get("buyer_id"));
                System.out.println("买家付款时间: " + params.get("gmt_payment"));
                System.out.println("买家付款金额: " + params.get("buyer_pay_amount"));
                // 更新订单未已支付
                Orders order = new Orders();
                order.setId(Long.valueOf(tradeNo));
                order.setStatus(2);
//                order.setCheckoutTime(params.get("gmt_payment"));
                shopOrderMapper.updateById(order);
            }
        }
        return "success";
    }
}

参数 Alipay.java

package com.kp.entity;
import lombok.Data;
@Data
public class AliPay {
    private String traceNo;
    private double totalAmount;
    private String subject;
    private String alipayTraceNo;
}

注意：在拦截器里面加上忽略alipay接口的配置，这很重要！

重要！前端配置！！

res.data.consignee以及其他两个参数都是下单时候的参数

async goToPaySuccess(){
    const params = {
        remark:this.note,
        payMethod:1,
        addressBookId:this.address.id
    }
    const res = await addOrderApi(params)
    console.log('params:', params);
    console.log('res:', res);
    if(res.code === 1){
        window.open(`http://localhost:8090/alipay/pay?subject=${res.data.consignee}&traceNo=${res.data.id}&totalAmount=${res.data.amount}`)
        this.$message.success('付款成功')
        this.load();
        })
    }else{
        this.$notify({ type:'warning', message:res.msg});
    }
},
