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

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)

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

3.1.3 utils包alipayconfig类

(请配置好该类,防止报错)

  1. appid:appid,沙箱应用提供的
  2. privatekey: 商户私钥,点击公钥证书查看
  3. 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">

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/>'
})

ok,重要的代码已经完全提供了。
