一.Mock.js
1、什么是Mock.js
Mock.js是一个用于生成模拟数据的JavaScript库。它能够模拟后端API接口,用于前端开发时进行接口调试和测试提高自动化测试效率。使用Mock.js可以快速创建虚拟的数据,并且可以设置数据的类型、格式和规则,从而模拟真实的数据响应。Mock.js支持生成随机数据、拦截Ajax请求以返回模拟数据、支持RESTful API风格等功能,能够提高前端开发效率,并且减少对后端接口的依赖。
数据类型丰富:支持生成随机的文本、数字、布尔值、日期、邮箱、链接、图片、颜色等。
拦截Ajax请求:不需要修改既有代码,就可以拦截Ajax请求,返回模拟的响应数据。
更多内容请查看Mock.js 官网
2、安装配置
1、安装
在你的项目的路径CMD窗口下载Mock.js。
npm i mockjs -D
-D表示只在开发环境中使用
在我们的package.json里面可以看到我们下载的mock.js
2、引入
为了只在开发环境使用mock,而打包到生产环境时自动不使用mock,我们可以在config目录中的dev.env.js和prod.env.js做一个配置。
dev.env.js
'use strict' const merge = require('webpack-merge') const prodEnv = require('./prod.env') module.exports = merge(prodEnv, { NODE_ENV: '"development"', MOCK: 'true' })
prod.env.js
'use strict' module.exports = { NODE_ENV: '"production"', MOCK: 'false' }
最后我们在main.js里面导入
// The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias. import Vue from 'vue' //开发环境下才会引入mockjs process.env.MOCK && require('@/mock') // 新添加1 import ElementUI from 'element-ui' // 新添加2,避免后期打包样式不同,要放在import App from './App';之前 import 'element-ui/lib/theme-chalk/index.css' import App from './App' import router from './router' // 新添加3----实例进行一个挂载 Vue.use(ElementUI) Vue.config.productionTip = false import axios from '@/api/http' import VueAxios from 'vue-axios' Vue.use(VueAxios, axios) /* eslint-disable no-new */ new Vue({ el: '#app', router, components: {App}, template: '<App/>' })
2、Mock.js的使用
1、定义测试数据文件
为每个*.vue定义单独的xxx-mock.js文件,并在其中添加自定义的json数据,还可以通过mockjs的模块生成随机数据信息,动态测试ajax请求效果。
创建src/mock/json目录,定义登录测试数据文件login-mock.js:
// const loginInfo = { // code: -1, // message: '密码错误' // } //使用mockjs的模板生成随机数据 const loginInfo = { 'code|-1-0': 0, 'message|3-10': 'msg' } export default loginInfo;
2、mock拦截ajax请求
在src/mock目录下创建index.js,定义拦截路由配置:
import Mock from 'mockjs' //引入mockjs,npm已安装 import action from '@/api/action' //引入请求地址 //全局设置:设置所有ajax请求的超时时间,模拟网络传输耗时 Mock.setup({ // timeout: 400 //延时400s请求到数据 timeout: 200 - 400 //延时200-400s请求到数据 }) //引登陆的测试数据,并添加至mockjs import loginInfo from '@/mock/json/login-mock.js' let s1 = action.getFullPath('SYSTEM_USER_DOLOGIN') Mock.mock(s1, "post", loginInfo) // Mock.mock(s1, /post|get/i, loginInfo)
3、模拟测试
使用登录页面模拟测试
<template> <div class="Login"> <el-form class="login-container"> <h1 class="title">用户登录</h1> <el-form-item label=""> <el-input type="text" v-model="username" placeholder="登录账号" autocomplete="off"></el-input> </el-form-item> <el-form-item label=""> <el-input type="password" v-model="password" placeholder="登录密码" autocomplete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" style="width:100%;" @click="doSubmit()">提交</el-button> </el-form-item> <el-row style="text-align: center;margin-top:-10px"> <el-link type="primary">忘记密码</el-link> <el-link type="primary" @click="gotoRegister()">用户注册</el-link> </el-row> </el-form> </div> </template> <script> export default { name: "Login", data() { return { username: "", password: "" } }, methods: { gotoRegister() { this.$router.push("/Register"); }, //提交事件 doSubmit() { //设置登录访问地址 let url = this.axios.urls.SYSTEM_USER_DOLOGIN; // 使用json格式进行传值 let params = { username: this.username, password: this.password } this.axios.post(url, params).then(r => { console.log(r); this.$message({ message: r.data.message, type: r.data.code == 0?'success': 'error' }); }).catch(e => { }); } } } </script> <style scoped> .login-wrap { box-sizing: border-box; width: 100%; height: 100%; padding-top: 10%; background-image: url(https://pic4.zhimg.com/v2-c5880f5a6d44766feb085c3ae94899c7_r.jpg); //background-image: url(); background-repeat: no-repeat; background-position: center right; background-size: 100%; } .login-container { border-radius: 10px; margin: 0px auto; width: 350px; padding: 30px 35px 15px 35px; background: #fff; border: 1px solid #eaeaea; text-align: left; box-shadow: 0 0 20px 2px rgba(0, 0, 0, 0.1); } .title { margin: 0px auto 40px auto; text-align: center; color: #505458; } </style>
二、首页导航、左侧菜单
1、页面搭建
在我们的components的公共文件夹里面写我们的公共页面。
AppMain.vue:布局容器组件
LeftAside.vue:左侧菜单组件
TopNav.vue:首页导航组件
根据vue组件之间传递数据实现element-ui的NavMenu菜单折叠、展开效果。
子组件往父组件传递数据(this.$emit):TopNav -> AppMain
父组件往子组件传递数据(props):AppMain -> LeftAside
1.1、图标定义
图标可以根据自己的风格来,我这里也提供在下面了,自己也可以进行更改。
1.2、AppMain.vue
<template> <el-container class="main-container"> <el-aside v-bind:class="asideClass"> <LeftNav></LeftNav> </el-aside> <el-container> <el-header class="main-header"> <TopNav></TopNav> </el-header> <el-main class="main-center">这是一个非常帅的主页</el-main> </el-container> </el-container> </template> <script> // 导入组件 import TopNav from '@/components/TopNav.vue' import LeftNav from '@/components/LeftNav.vue' // 导出模块 export default { }; </script> <style scoped> .main-container { height: 100%; width: 100%; box-sizing: border-box; } .main-aside-collapsed { /* 在CSS中,通过对某一样式声明! important ,可以更改默认的CSS样式优先级规则,使该条样式属性声明具有最高优先级 */ width: 64px !important; height: 100%; background-color: #334157; margin: 0px; } .main-aside { width: 240px !important; height: 100%; background-color: #334157; margin: 0px; } .main-header, .main-center { padding: 0px; border-left: 2px solid #333; } </style>

1.5、index.js
在index,js里面进行路由配置
import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' import Login from '@/views/Login' import Register from '@/views/Register' import AppMain from '@/components/AppMain' import LeftNav from '@/components/LeftNav' import TopNav from '@/components/TopNav' Vue.use(Router) export default new Router({ routes: [ { path: '/Login', name: 'Login', component: Login }, { path: '/Register', name: 'Register', component: Register }, { path: '/AppMain', name: 'AppMain', component: AppMain, children: [{ path: '/LeftNav', name: 'LeftNav', component: LeftNav }, { path: '/TopNav', name: 'TopNav', component: TopNav }] } ] })
2、功能实现
2.1、AppMain.vue
// 导出模块 export default { //把顶部导航和左边导航进行绑定在main components: { TopNav, LeftNav }, data() { return { asideClass: 'main-aside' } }, created() { this.$root.Bus.$on('sjm', v => { this.asideClass = v ? 'main-aside-collapsed' : 'main-aside'; }); } };
2.2、LeftNav.vue
export default { data() { return { collapsed: false } }, created() { this.$root.Bus.$on('sjm', v => { this.collapsed = v; }); } }
2.3、TopNav.vue
export default { data() { return { collapsed: false, imgshow: require('@/assets/img/show.png'), imgsq: require('@/assets/img/sq.png') } }, methods: { //图标的切换 doToggle() { this.collapsed = !this.collapsed; //定义一个事件名,将是否折叠变量放入总线 this.$root.Bus.$emit('sjm', this.collapsed) }, exit() { this.$router.push('/Login'); } } }
2.4、main.js
data() { return { Bus: new Vue() } }
