续接Django REST Framework，使用Vite构建Vue3的前端项目

1. 后台管理系统主界面框架搭建

后台系统主界面搭建

新建后台管理文件目录

完成后台整体布局

// 1.主界面 index.vue

<script setup lang="ts">

</script>

<template>
    <el-container  class="layout">
        <el-aside width="200px" class="aside">Aside</el-aside>
        <el-container>
            <el-header class="header">Header</el-header>
            <el-main class="main">Main</el-main>
        </el-container>
    </el-container>
  </template>


<style scoped>
.layout {
    height: 100%;
}

.aside {
  background-color: #304156;
}
.header {
  background-color: lightblue;
  height: 50px;
  border-bottom: 1px solid #e5e5e5;
  display: flex;
  align-items: center;
  justify-content: space-between;
}
</style>

// 2.配置路由
import { createRouter, createWebHistory, RouteRecordRaw } from "vue-router";
import Index from '../layout/index.vue'
const routes: Array<RouteRecordRaw>= [
    {
        path: "/",
        // name: 'Home',
        component: Index,    
    },
    
]

// 创建一个 vue-router对象
const router = createRouter({
    history: createWebHistory(),
})

// 暴露接口
export default router

3.app.vue引入路由
<script setup lang="ts">

</script>
<template>
  <router-view></router-view>
</template>

<style scoped>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}
 
</style>

后台页面满屏显示

1.style.css 注销 #app{}
2.index.html添加样式
<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <link rel="icon" type="image/svg+xml" href="/vite.svg" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>后台管理</title>
  </head>
<!--添加样式-->
  <style>
    html, body,#app{
      padding: 0px;
      margin: 0px;
      height: 100%;
      width: 100%;
    }
  </style>
  <body>
    <div id="app"></div>
    <script type="module" src="/src/main.ts"></script>
  </body>
</html>

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import router from './router' // 导入路由文件
import * as ElementPlusIconsVue from '@element-plus/icons-vue' // 导入所以 icon图标

import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css' 

// 创建app
const app= createApp(App)

app.use(router).use(ElementPlus).mount('#app')

// 遍历所有 icon将每个图标以组件方式加载到app中
Object.keys(ElementPlusIconsVue).forEach((key) => {
    app.component(key, ElementPlusIconsVue[key as keyof typeof ElementPlusIconsVue]); // 注册成全局组件
})

侧边栏收缩思路

控制菜单栏收缩---->Menu.vue---><el-menu :collapse=true></el-menu>
操作菜单栏收缩---->Collapse.vue
// 点击按钮实现切换(true/false) Collapse.vue
<script setup lang="ts">
// 导入vue
import {ref} from 'vue'
let isCollapsed = ref(false)
const changeCollapse = ()=>{
    isCollapsed.value =!isCollapsed.value 
    console.log(isCollapsed.value )
}

</script>

<template>
   <!-- 使用全局定义的折叠图标 -->
    <el-icon>
        <component class="icons" is="Fold" @click="changeCollapse"></component>
    </el-icon>
</template>
<style scoped>
.el-icon{
    font-style: 22px;
    margin-right: 10px;
}
</style>

跨组件传值{
    父子组件---->直接传值{
        // 父组件定义传递的值
        // 导入vue
        import {ref} from 'vue'
        // 定义待传递的值
        let name = ref('admin')
        // 传递给子组件
        <template>
            <UserInfo :username='name'></UserInfo>
        </template>
        // 子组件接收父组件传递过来的值
        defineProps<{username: string}>();
        // 调用值
        {{ username }}
        
}
    兄弟组件---->vuex
}

2. Vuex实现组件间的传值

vuex是基于vue框架的一个状态管理库。可以管理复杂应用的数据状态，比如兄弟组件的通信、多层嵌套的组件的传值等等

store---store是yuex的核心对象，它记录了整个vue应用的数据状态以及操作数据的方式。
state---就是store操作的数据状态对象,
mutation---提供了一种简单易用的同步的方式改变state的状态。
getter---获取state中数据对象

vuex安装

// 安装最新版 vuex
npm install vuex@next --save

// 新建 store文件夹并在文件夹下新建 index.ts导入vuex模块

import { createStore } from 'vuex'

// 报错：/node_modules/vuex/types/index.d.ts', but this result could not be resolved when respecting package.json "exports". 

// 解决报错 node_modules\vuex\package.json在exports字段中添加"types": "./types/index.d.ts"

store对象创建

// 导入 vuex 模块
import { createStore } from 'vuex'
// 定义实体（存储结构）
export interface MyStore {
    // 控制侧边栏收缩
    collapse: boolean,
}

// 创建store对象
export const store = createStore<MyStore>({
    // 初始状态
    state: {
        collapse: false, // 侧边栏收缩
    },
    //  mutations 用于更改 Vuex 的 store 中的状态
    mutations: {
        toggleCollapse(state: MyStore) {
            state.collapse =!state.collapse
        },
    },
    // actions 用于提交 mutations，可以包含异步操作
    actions: {
        toggleCollapse({ commit }) {
            commit('toggleCollapse')
        },
    },
    // getters 用于获取状态的某些派生数据
    getters: {
        // 侧边栏是否收缩
        isCollapse(state: MyStore) {
            return state.collapse
        },
    },
})
// 暴露
export default store;

store对象注册

// 注册到全局变量
import store from './store' // 导入创建的store对象

app.use(store).use(router).use(ElementPlus).mount('#app')

侧边栏收缩功能完成

// Menu.vue
// 组件中调用vuex中定义的store
// 导入usestore的方法
import { useStore } from 'vuex'
// 获取当前vuex的store对象
const store = useStore()
// 导入计算
import { computed } from 'vue' 
// 获取store->state中的collapse值
const isCollapse = computed(()=>{
    return store.getters['isCollapse']
})

// 在标签中实现绑定
<el-menu :collapse = isCollapse></el-menu>

// 解决侧边栏收缩 logo显示问题 侧边栏不是收缩状态时展示
<MenuLogo class="layout-logo" v-if="!isCollapse"></MenuLogo>


// Collaspe.vue
// 导入usestore的方法
import { useStore } from 'vuex'
// 获取当前vuex的store对象
const store = useStore();
// 导入计算
import { computed } from 'vue' 
// 获取store->state中的collapse值
const isCollapse = computed(()=>{
    return store.getters['isCollapse']
})

// 点击切换收缩事件
const changeCollapse=()=>{
    // 切换collapse的值
    store.commit('toggleCollapse')
}


// 使用三元表达式判断收缩图标，此时全局定义的icon图标将失效需重新导入
import { Fold,Expand } from '@element-plus/icons-vue';
<component class="icons" :is="isCollapse? Fold: Expand " @click="changeCollapse"></component>

3. Vue-router实现侧边栏导航

实现侧边栏导航

// router/index.ts 配置路由

const routes: Array<RouteRecordRaw>= [
    // 首页
    {
        path: "/",
        name: 'Layout',
        component: Layout,
        // 自动跳转
        redirect: '/dashboard',
        children:[
            {
                path: '/dashboard',
                name: 'Dashboard',
                component: () => import('../views/index/Dashboard.vue')
            }
        ]
        
    },
    // 基础数据--->院系信息、专业信息、教师信息
    {
        path: '/basic',
        name: 'Basic',
        component: Layout,
        children: [
            {
                path: '/basic/faculty',
                name: 'Faculty',
                component: () => import('../views/basic/Faculty.vue')
            },
            {
                path: '/basic/major',
                name: 'Major',
                component: () => import('../views/basic/Major.vue')
            },
            {
                path: '/basic/teacher',
                name: 'Teacher',
                component: () => import('../views/basic/Teacher.vue')
            }
        ]
            
    },
    // 学生管理
    {
        path: '/student',
        name:'Student',
        component: Layout,
        children: [
            {
                path: '/student/info',
                name: 'StudentInfo',
                component: () => import('../views/student/Info.vue')
            },
            {
                path: '/student/exam',
                name: 'StudentExam',
                component: () => import('../views/student/Exam.vue')
            },
            {
                path: '/student/image',
                name: 'StudentImage',
                component: () => import('../views/student/Image.vue')
            }
        ]
    },
    // 用户管理
    {
        path: '/user',
        name: 'User',
        component: Layout,
        children: [
            {
                path: '/user/account',
                name: 'UserAccount',
                component: () => import('../views/user/Account.vue')
            },
            {
                path: '/user/roles',
                name: 'UserRoles',
                component: () => import('../views/user/Roles.vue')
            },
            {
                path: '/user/menu',
                name: 'UserMenu',
                component: () => import('../views/user/Menu.vue')
            },
            {
                path: '/user/permission',
                name: 'UserPermission',
                component: () => import('../views/user/Permission.vue')
            }
        ]
    }
    
]

// layout/index.vue引入路由在指定区域显示

<el-main class="main"><router-view></router-view></el-main>

// layout/menu/Menu.vue 配置点击侧边栏切换路由
<el-menu active-text-color="#ffd04b" background-color="#304156" class="el-menu-vertical-demo" default-active="2"
        text-color="#fff"
        :collapse = isCollapse
        router
        >

4. 捕获路由信息自动生成面包屑导航

自动生成面包屑导航

// 路由添加 meta字段记录标题名

const routes: Array<RouteRecordRaw>= [
    // 首页
    {
        path: "/",
        name: 'Layout',
        component: Layout,
        // 自动跳转
        redirect: '/dashboard',
        children:[
            {
                path: '/dashboard',
                name: 'Dashboard',
                component: () => import('../views/index/Dashboard.vue'),
                meta: { title: '首页' }
            }
        ]
        
    },
    // 基础数据--->院系信息、专业信息、教师信息
    {
        path: '/basic',
        name: 'Basic',
        component: Layout,
        meta: { title: '基础数据' },
        children: [
            {
                path: '/basic/faculty',
