沙箱支付实现扫码支付教程（前后端分离版）

利用沙箱支付实现电脑扫码支付

一、准备工作
二、效果展示
- 三、实现代码
- - 3.1 后台代码（我这里利用的是SpringBoot集成的SSM,当然不使用SpringBoot也可以）
  - 3.2 前台代码（前台是利用脚手架搭建的Vue项目）

一、准备工作

1、注册支付宝开放平台账号，成为开发者。
地址：https://open.alipay.com/platform/home.htm

2、进入沙箱，进行配置。

3.我们可以看到这个界面

4.后面需要使用的参数

APPID
商户私钥（使用系统默认密钥的公钥模式，点击查看获取）
支付宝公钥
支付宝网关

5、手机上下载沙箱支付宝（到时候支付用这个支付宝支付）

6、下载好支付宝沙箱版后，登录支付宝提供的账号

二、效果展示

1、随手写的一个前台vue界面

2、进入确定订单界面，可以添加商品描述

3、跳转支付界面，利用沙箱支付宝完成支付

4、完成支付

5、跳回自己设置的界面

END…

三、实现代码

3.1 后台代码（我这里利用的是SpringBoot集成的SSM,当然不使用SpringBoot也可以）

3.1.1 pom.xml文件
不用全部的，重点是：支付宝sdk包、fastjson

3.1.2 model包

package com.zking.springboot02.model;import lombok.Data;/*** 支付实体对象* 根据支付宝接口协议，其中的属性名，必须使用下划线，不能修改* * @author 借我丹青妙笔*/
@Data
public class AlipayBean {private static final long serialVersionUID = 1L;/*** 商户订单号，必填**/private String out_trade_no;/*** 订单名称，必填*/private String subject;/*** 付款金额，必填* 根据支付宝接口协议，必须使用下划线*/private String total_amount;/*** 商品描述，可空*/private String body;/*** 超时时间参数*/private String timeout_express= "10m";/*** 产品编号*/private String product_code= "FAST_INSTANT_TRADE_PAY";public String getOut_trade_no() {return out_trade_no;}public void setOut_trade_no(String out_trade_no) {this.out_trade_no = out_trade_no;}public String getSubject() {return subject;}public void setSubject(String subject) {this.subject = subject;}public String getTotal_amount() {return total_amount;}public void setTotal_amount(String total_amount) {this.total_amount = total_amount;}public String getBody() {return body;}public void setBody(String body) {this.body = body;}
}

3.1.3 utils包
AlipayConfig类（请配置好该类,防止报错）

appId：APPID,沙箱应用提供的
privateKey: 商户私钥,点击公钥证书查看
returnUrl : 支付完成后跳转的页面，例如我填的是：http://localhost:8088/

3.1.6 application.yml文件

server:port: 8080 #端口号servlet:context-path: /s02 #项目名

3.2 前台代码（前台是利用脚手架搭建的Vue项目）

3.2.1 src下api包下action.js文件

/*** 对后台请求的地址的封装，URL格式如下：* 模块名_实体名_操作*/
export default {//服务器'SERVER': 'http://localhost:8080/s02','alipay' : 'http://localhost:8080/s02/pay/alipay',//获得请求的完整地址，用于mockjs测试时使用'getFullPath': k => {return this.SERVER + this[k];}
}

3.2.2 src下api包下http.js文件

/*** vue项目对axios的全局配置*/
import axios from 'axios'
import qs from 'qs'//引入action模块，并添加至axios的类属性urls上
import action from '@/api/action'
axios.urls = action// axios默认配置
axios.defaults.timeout = 10000; // 超时时间
// axios.defaults.baseURL = 'http://localhost:8080/crm'; // 默认地址
axios.defaults.baseURL = action.SERVER;//整理数据
// 只适用于 POST,PUT,PATCH，transformRequest` 允许在向服务器发送前，修改请求数据
axios.defaults.transformRequest = function(data) {data = qs.stringify(data);return data;
};// 请求拦截器
axios.interceptors.request.use(function(config) {// let jwt = sessionStorage.getItem('jwt');// if (jwt) {//  config.headers['jwt'] = jwt;// }return config;
}, function(error) {return Promise.reject(error);
});// 响应拦截器
axios.interceptors.response.use(function(response) {return response;
}, function(error) {return Promise.reject(error);
});export default axios;

3.2.3 src下router下index.js文件

import Vue from 'vue'
import Router from 'vue-router'
import Shop from '@/views/Shop'
import buy from '@/views/buy'Vue.use(Router)export default new Router({routes: [{path: '/',name: 'Shop',component: Shop},{path: '/buy',name: 'buy',component: buy}]
})

3.2.4 src下views下Shop.vue文件

<template><el-table :data="tableData" style="width: 100%"><el-table-column prop="out_trade_no" label="编号"></el-table-column><el-table-column prop="subject" label="订单名称" ></el-table-column><el-table-column prop="total_amount" label="付款金额"></el-table-column><el-table-column  label="操作"><template slot-scope="scope"><el-button @click="toBuy(scope.row)" type="text" size="small">去支付</el-button></template></el-table-column></el-table></template><script>export default {name: "Shop",data: function() {return {tableData: [{out_trade_no: '101',subject: 'Java从入门到入土',total_amount: 33}, {out_trade_no: '202',subject: 'Mysql删库跑路指南',total_amount: 44}, {out_trade_no: '303',subject: 'Java编程思想',total_amount: 89}, {out_trade_no: '404',subject: 'Java设计模式',total_amount: 56}]};},methods: {toBuy(row){console.log(row);//利用$router.push进行跳转this.$router.push({//path后面跟跳转的路由地址path: '/buy',//name后面跟跳转的路由名字（必须有亲测，不使用命名路由会传参失败）name: 'buy',params: {//imgsListsUrl2是自己定义的名字，this.imgsListsUrl是要被传递的值payInfo: row}})}},created: function() {}}
</script><style>
</style>

3.2.5 src下views下buy.vue文件

<template><div class="main"><center><div class="box"><h2>确定订单</h2><el-form :model="payInfo" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm"><el-form-item label="订单号" prop="out_trade_no"><el-input v-model="payInfo.out_trade_no" readonly="true"></el-input></el-form-item><el-form-item label="商品名称" prop="subject"><el-input v-model="payInfo.subject" readonly="true"></el-input></el-form-item><el-form-item label="商品价格" prop="total_amount"><el-input v-model="payInfo.total_amount" readonly="true"></el-input></el-form-item><el-form-item label="商品描述" prop="body"><el-input v-model="payInfo.body"></el-input></el-form-item><el-button type="primary" plain @click="submit" style="width: 100%;" round>付款</el-button></el-form></div></center></div>
</template>
<script>//import axios from 'axios'export default {name: "buy",data() {return {payInfo: {out_trade_no: '',subject: '',total_amount: null,body: ''}}},mounted() {//this.$route.params.imgsListsUrl2是传过来的参数var time = new Date();this.payInfo = this.$route.params.payInfothis.payInfo.out_trade_no = time.getTime();},methods: {submit() {var url = this.axios.urls.alipay;//得到api下action.js中的alipaythis.axios.post(url, this.payInfo).then(resp => {//调用后台方法console.log(resp);const divForm = document.getElementsByTagName('div')if (divForm.length) {document.body.removeChild(divForm[0])}const div = document.createElement('div')div.innerHTML = resp.data.msg // data就是接口返回的form 表单字符串document.body.appendChild(div)document.forms[0].setAttribute('target', '_blank') // 新开窗口跳转document.forms[0].submit()}).catch(resp => {console.log(resp);});}}}
</script>
<style scoped>.box {width: 800px;}.left {width: 85px;padding-top: 5px;font-size: 15px;}.right {width: 400px;}
</style>

3.2.6 src下main.js文件

import Vue from 'vue'
import ElementUI from 'element-ui' //新添加1
import 'element-ui/lib/theme-chalk/index.css' //新添加2，避免后期打包样式不同，要放在import App from './App';之前import axios from '@/api/http'             //vue项目对axios的全局配置import App from './App'
import router from './router'import VueAxios from 'vue-axios'
Vue.use(VueAxios,axios)Vue.use(ElementUI)   //新添加3
Vue.config.productionTip = false/* eslint-disable no-new */
new Vue({el: '#app',router,components: { App },template: '<App/>'
})

END

OK,重要的代码已经完全提供了。

声明：实现沙箱支付可以让我们了解如何调用如支付宝的接口，让我们理解接口的调用。
对业务开发有极大的帮助与提升。也希望每个看完这篇博客的小伙伴都能实现沙箱支付的扫码支付功能，若有问题，请留下你的评论，欢迎互相探讨。
