一.Mock
1.1.什么是Mock.js
Mock.js是一个模拟数据生成器,用于生成随机数据、模拟请求响应等。它可以帮助前端开发人员在开发过程中模拟接口数据,减少对后端接口的依赖。Mock.js提供了丰富的数据模板语法,可以生成各种类型的随机数据,如数字、字符串、日期、布尔值、数组、对象等。同时,Mock.js还提供了拦截Ajax请求的功能,可以直接拦截请求并返回模拟数据,方便进行接口开发和测试。Mock.js在前端开发中被广泛应用,可以提高开发效率,方便进行调试和功能开发。
1.2.特点
Mock.js的主要特点包括以下几个方面:
随机数据生成:Mock.js提供了丰富的数据模板语法,可以生成各种类型的随机数据,包括数字、字符串、日期、布尔值、数组、对象等。这使得开发人员可以很方便地生成需要的测试数据,避免手动编写大量的假数据。
数据模板定义:Mock.js支持使用数据模板定义数据结构,通过预先定义的模板规则,可以生成符合预期的数据。模板定义灵活且易于修改,可以根据需求进行定制。
响应拦截与模拟:Mock.js可以拦截Ajax请求,模拟后端接口的响应数据,从而实现前端与后端的分离开发。开发人员无需真实的后端接口,即可进行功能开发和测试,减少了开发的依赖和耦合。
数据延迟与动态数据:Mock.js支持对模拟数据添加延迟和动态数据的配置。延迟可以模拟真实接口的网络延迟,以验证前端在异步请求中的处理能力。动态数据可以根据实际情况生成变化的数据,使模拟数据更加真实。
支持跨域请求:Mock.js支持跨域请求的拦截和模拟,方便前端开发人员在本地进行接口联调和测试,无需关注跨域限制。
总之,Mock.js提供了一套简单、高效、实用的模拟数据生成方案,使前端开发人员能够更加轻松地进行接口开发和测试,提高开发效率和质量。
1.3.安装与配置
1.3.1. 安装mock.js
Win+R输入cmd打开命令提示符,执行以下命令进行mock.js安装,如下:
npm i mockjs -D
注:-D表示只在开发环境中使用。
package.json中有以下代码即安装成功,如下:
安装完成之后,我们需要引入mock.js。
1.3.2.引入mock.js
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
html'use strict' const merge = require('webpack-merge') const prodEnv = require('./prod.env') module.exports = merge(prodEnv, { NODE_ENV: '"development"', MOCK: 'true' })
- prod.env.js
html'use strict' module.exports = { NODE_ENV: '"production"', MOCK: 'false' }
- main.js
html//开发环境下才会引入mockjs process.env.MOCK && require('@/mock')
1.4.mockjs使用
1.4.1.定义测试数据文件
在src目录下新建一个mock包,在mock包下定义测试数据文件,目录如下:
login-mock.js:
html
// 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;
1.4.2.mock拦截Ajax请求
在src/mock目录下创建index.js,定义拦截路由配置,如下:
index.js:
html
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)
1.4.3.界面代码优化
由于此次展示无需用到后端代码,所以博主就将昨天前后端交互用到的后端代码给备注了,换上了正常前后端分离开发所用的mock.js代码,如下:
Login.vue:
html
<template>
<div id="app">
<template>
<div class="login-wrap">
<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>
</div>
</template>
<script>
import axios from 'axios'
import qs from 'qs'
export default {

return {

}
}
,methods:{
gotoRegister(){
// router-like相当于a
// location.href 相当于this.$router.push
this.$router.push('/Register');
},
doSubmit(){
let url =this.axios.urls.SYSTEM_USER_DOLOGIN;
let params ={
username:this.username,
password:this.password
}
// $.ajax then相当于success
// axios.get(url,{params:params}).then(r=>{
// console.log(r);
// if(r.data.success){
// this.$message({
// message:r.data.msg,
// type: 'success'
// });
// }else{
// this.$message.error(r.data.msg);
// }
// }).cath(e=>{
// })
this.axios.post(url,params).then(r => {
console.log(r);
// //如果携带的参数数据跟后端数据对应正确,说明登入成功,提示
// if (r.data.success) {
// this.$message({
// showClose: true,
// message: r.data.msg,
// type: 'success'
// });
// } else {
// //如果携带的参数数据跟后端数据对应错误,说明登入失败,提示
// this.$message.error(r.data.msg);
// }
this.$message({
message: r.data.message,
type: r.data.code == 0 ?'success' : 'error'
});
this.$router.push('/AppMain');
}).catch(e => {
console.log(e);
});
}
}
}

二.总线
2.1.是什么
**总线(Bus)**是计算机系统中用于在各个组件之间传输数据和控制信号的通道。它是计算机内部各个组件之间进行通信和协调工作的重要桥梁。
在计算机系统中,总线可分为多种类型,常见的包括数据总线、地址总线和控制总线:
**数据总线(Data Bus):**用于在计算机内部不同组件之间传输数据。数据总线的位宽决定了一次可以传输的数据量,例如32位数据总线表示每次可以传输32位的数据。
**地址总线(Address Bus):**用于在计算机内部传输内存或者外设的地址信息。地址总线的位宽决定了CPU能够寻址的地址空间大小。
**控制总线(Control Bus):**用于传输各种控制信号,如读写控制、时钟信号、中断信号等。控制总线是计算机内部各个组件之间进行协调和控制的重要媒介。
总线的设计和规划对于计算机系统的性能和功能有着重要影响。不同类型的总线在计算机内部承担不同的功能和作用,通过总线的高效运作,各个组件能够有效地进行数据传输和协同工作,实现计算机的功能和任务。
2.2.前期准备
依需用到案例展示,我们需要用到三个组件和部分图片搭建页面,如下:
三个组件分别如下:
AppMain.vue:
html
<template>
<el-container class="main-container">
<el-aside v-bind:class="asideClass">

<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:{

},
data(){
return{
asideClass:'main-aside'
}
},

this.$root.Bus.$on('aaa',v=>{
this.asideClass = v ? 'main-aside-collapsed' : 'main-aside';
});
}
};
</script>
<style scoped>
.main-container {

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;

}
</style>

准备相对应的图片以下图片:
2.3.配置组件与路由关系
2.3.1. 配置组件
在router包下加入以下代码,如下:
html
import AppMain from '@/components/AppMain'
import LeftNav from '@/components/LeftNav'
import TopNav from '@/components/TopNav'
2.3.2.配置路由关系
在router包下加入以下代码,如下:
html
{
path: '/AppMain',
name: 'AppMain',
component: AppMain,
children: [
{
path: '/LeftNav',
name: 'LeftNav',
component: LeftNav
},
{
path: '/TopNav',
name: 'TopNav',
component: TopNav
}
]
}]
main.js:
html
// 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:trur && require('@/mock')
// 生产环境:false && require('@/mock')
//开发环境下才会引入mockjs
process.env.MOCK && require('@/mock')
// 1.导入ElementUI依赖
import ElementUI from 'element-ui'
// 2.导入ElementUI样式,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'
// 3增加ElementUI实例
Vue.use(ElementUI)
Vue.config.productionTip = false
// 在main.js文件中引入vue-axios模块
import axios from '@/api/http'
import VueAxios from 'vue-axios'
// 在main.js文件中引入vue-axios模块
Vue.use(VueAxios,axios)
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
data(){
return{
Bus:new Vue()
}
},
components: { App },
template: '<App/>'
})
