1. 安装：
npm install crypto-js 或者yarn add crypto-js
2. 引入crypto-js，并封装加密解密的方法

3 utils.js
/** * 工具类 */import secureUtils from './secureUtil'//加密解密export function demoRequest(data) { var encryptMessage = secureUtils.encryption(data); return encryptMessage;}export function demoResponse(data) { var decryptMessage = secureUtils.decryption(data); return decryptMessage;}export default { demoRequest, demoResponse}
4. 在入口文件main.js中使用
import Utils from './utils/utils'
Vue.prototype.$Utils = Utils
5 在组件中使用
加密：
this.$Utils.demoRequest(JSON.stringify(data))
要加密得数据必须先转为字符串
解密：
data = JSON.parse(this.$Utils.demoResponse(res.data))
解密完转换为JSON对象
