一、Mock.js
1.1.什么是Mock.js
前后端分离开发开发过程当中,经常会遇到以下几个尴尬的场景:
- 老大,接口文档还没输出,我的好多活干不下去啊!
- 后端小哥,接口写好了没,我要测试啊!
前后端分离之后,前端迫切需要一种机制,不再需要依赖后端接口开发,而今天的主角mockjs就可以做到这一点。
Mock.js是一个模拟数据的生成器,用来帮助前端调试开发、进行前后端的原型分离以及用来提高自动化测试效率。
众所周知Mock.js因为两个重要的特性风靡前端:
- 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。
1.2.安装与配置
npm i mockjs -D
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,如下:
- dev.env.js
module.exports = merge(prodEnv, { NODE_ENV: '"development"', MOCK: 'true' })
- prod.env.js
module.exports = { NODE_ENV: '"production"', MOCK: 'false' }
- main.js
//开发环境下才会引入mockjs process.env.MOCK && require('@/mock')
1.3使用
创建mock目录,mock下创建index.js以及json文件夹,在JSON文件夹中创建login-mock.js
- index.js 将mock与url绑定
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400ms请求到数据 timeout: 200 - 400 //延时200-400ms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)
- login-lock.js code随机0或-1,msg随机3-10个’msg’
//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;
- 修改Login.vue中的doSubmit()的内容
doSubmit: function () { let params = { username: this.username, password: this.password }; console.log(params); let url = this.axios.urls.SYSTEM_USER_DOLOGIN; this.axios.post(url, params).then(response => { console.log(response); if (response.data.code == 0) { this.$message({ message: response.data.message, type: 'success' }) } else { this.$message({ message: response.data.message, type: 'error' }) } }).catch(error => { console.log(error); }); }
二、登录注册跳转
使用this.$router.push({})
2.1.在views中添加Register.vue
<template> <div class="login-wrap"> <el-form class="login-container"> <h1 class="title">用户注册</h1> <el-form-item label=""> <el-input type="text" v-model="username" placeholder="登录账号" autocomplete="off"></el-input> </el-form-item> <el-form-item label=""> <el-input type="password" v-model="password" placeholder="登录密码" autocomplete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" style="width:100%;" @click="doSubmit()">提交</el-button> </el-form-item> <el-row style="text-align: center;margin-top:-10px"> <el-link type="primary">忘记密码</el-link> <el-link type="primary" @click="gotoLogin()">用户登录</el-link> </el-row> </el-form> </div> </template> <script> export default { name: 'Login', data: function () { return { username: "admin", password: "123" } }, methods: { doSubmit: function () { }, gotoLogin(){ this.$router.push({path: '/'}) } } } </script> <style scoped> .login-wrap { box-sizing: border-box; width: 100%; height: 100%; padding-top: 10%; /* background-color: #112346; */ 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>
2.2.在Login.vue中的methods中添加gotoRegister方法
gotoRegister(){ this.$router.push({path: '/register'}) }
2.3.在router/index.js中注册路由
import Register from '@/views/Register' //以下内容添加到routes中 { path: '/register', name: 'Register', component: Register }
三、组件通信(总线)
3.1 在main.js中添加内容
//在new Vue中添加 data(){ return{ Bus: new Vue({}) } }
3.2.在components中添加内容
- AppMain.vue
<template> <el-container class="main-container"> <el-aside v-bind:class="asideClass"> <LeftNav></LeftNav> </el-aside> <el-container> <el-header class="main-header"> <TopNav></TopNav> </el-header> <el-main class="main-center">Main</el-main> </el-container> </el-container> </template> <script> // 导入组件 import TopNav from '@/components/TopNav.vue' import LeftNav from '@/components/LeftNav.vue' // 导出模块 export default { components: {LeftNav, TopNav}, data() { return { asideClass: 'main-aside' } }, created() { this.$root.Bus.$on('doCollapsed', v => { //v指的是topNav传递过来的this.collapsed this.asideClass = v ? 'main-aside-collapsed' : 'main-aside'; }); } }; </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; transition: width 0.6s ease; } .main-aside { width: 240px !important; height: 100%; background-color: #334157; margin: 0px; transition: width 0.6s ease; } .main-header,.main-center { padding: 0px; border-left: 2px solid #333; } </style>
- TopNav.vue
<template> <!-- <el-menu :default-active="activeIndex2" class="el-menu-demo" mode="horizontal" @select="handleSelect" background-color="#545c64" text-color="#fff" active-text-color="#ffd04b"> <el-menu-item index="1">处理中心</el-menu-item> <el-submenu index="2"> <template slot="title">我的工作台</template> <el-menu-item index="2-1">选项1</el-menu-item> <el-menu-item index="2-2">选项2</el-menu-item> <el-menu-item index="2-3">选项3</el-menu-item> <el-submenu index="2-4"> <template slot="title">选项4</template> <el-menu-item index="2-4-1">选项1</el-menu-item> <el-menu-item index="2-4-2">选项2</el-menu-item> <el-menu-item index="2-4-3">选项3</el-menu-item> </el-submenu> </el-submenu> <el-menu-item index="3" disabled>消息中心</el-menu-item> <el-menu-item index="4"><a href="https://www.ele.me" target="_blank">订单管理</a></el-menu-item> </el-menu> --> <el-menu class="el-menu-demo" mode="horizontal" background-color="#334157" text-color="#fff" active-text-color="#fff"> <el-button class="buttonimg"> <img class="showimg" :src="collapsed?imgshow:imgsq" @click="doToggle()"> </el-button> <el-submenu index="2" class="submenu"> <template slot="title">超级管理员</template> <el-menu-item index="2-1">设置</el-menu-item> <el-menu-item index="2-2">个人中心</el-menu-item> <el-menu-item @click="exit()" index="2-3">退出</el-menu-item> </el-submenu> </el-menu> </template> <script> export default { data() { return { collapsed: false, imgshow: require('@/assets/img/show.png'), imgsq: require('@/assets/img/sq.png') } }, methods: { doToggle() { this.collapsed = !this.collapsed; this.$root.Bus.$emit('doCollapsed', this.collapsed); }, exit(){ this.$router.push({path:'/'}) } } } </script> <style scoped> .el-menu-vertical-demo:not(.el-menu--collapse) { border: none; } .submenu { float: right; } .buttonimg { height: 60px; background-color: transparent; border: none; } .showimg { width: 26px; height: 26px; position: absolute; top: 17px; left: 17px; } .showimg:active { border: none; } </style>
- LeftNav.vue
<template> <el-menu default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed"> <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> --> <div class="logobox"> <img class="logoimg" src="../assets/img/logo.png" alt=""> </div> <el-submenu index="1"> <template slot="title"> <i class="el-icon-location"></i> <span>导航一</span> </template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="1-1">选项1</el-menu-item> <el-menu-item index="1-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="1-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="1-4"> <template slot="title">选项4</template> <el-menu-item index="1-4-1">选项1</el-menu-item> </el-submenu> </el-submenu> <el-menu-item index="2"> <i class="el-icon-menu"></i> <span slot="title">导航二</span> </el-menu-item> <el-menu-item index="3" disabled> <i class="el-icon-document"></i> <span slot="title">导航三</span> </el-menu-item> <el-menu-item index="4"> <i class="el-icon-setting"></i> <span slot="title">导航四</span> </el-menu-item> </el-menu> </template> <script> export default { data() { return { collapsed: false } }, created() { this.$root.Bus.$on('doCollapsed', v => { //v指的是topNav传递过来的this.collapsed this.collapsed = v; }); } } </script> <style> .el-menu-vertical-demo:not(.el-menu--collapse) { width: 240px; min-height: 400px; } .el-menu-vertical-demo:not(.el-menu--collapse) { border: none; text-align: left; } .el-menu-item-group__title { padding: 0px; } .el-menu-bg { background-color: #1f2d3d !important; } .el-menu { border: none; } .logobox { height: 40px; line-height: 40px; color: #9d9d9d; font-size: 20px; text-align: center; padding: 20px 0px; } .logoimg { height: 40px; } </style>
3.3.在router/index.js中配置路由
{ path: '/appMain', name: 'AppMain', component: AppMain, children: [{ path: '/TopNav', name: 'TopNav', component: TopNav },{ path: '/leftNav', name: 'LeftNav', component: LeftNav } ] }
4.登出
- 修改topNav的内容
//在methods中添加exit()方法 exit(){ this.$router.push({path:'/login'}) }
