二、大事件项目介绍和创建
在线演示:https://fe-bigevent-web.itheima.net/login
接口文档:https://apifox.com/apidoc/shared-26c67aee-0233-4d23-aab7-08448fdf95ff/api-93850835
基地址:http://big-event-vue-api-t.itheima.net
三、pnpm包管理器 - 创建项目
优势:比同类工具快2倍左右、节省磁盘空间··· https://www.pnpm.cn/
安装方式:
npm install -g pnpm
创建项目:
pnpm create vue
常用命令:
npm | yarn | pnpm |
npm install | yarn | pnpm install |
npm install axios | yarn add axios | pnpm add axios |
npm install axios -D | yarn add axios -D | pnpm add axios -D |
npm uninstall axios | yarn remove axios | pnpm remove axios |
npm run dev | yarn dev | pnpm dev |
四、Eslint配置代码风格
配置文件:.eslintrc.cjs
1. prettier 风格配置 https://prettier.io
2. vue组件名称多单词组成(忽略index.vue)
3. props解构(关闭)
/* eslint-env node */
require('@rushstack/eslint-patch/modern-module-resolution')
module.exports = {
root: true,
'extends': [
'plugin:vue/vue3-essential',
'eslint:recommended',
'@vue/eslint-config-prettier/skip-formatting'
],
parserOptions: {
ecmaVersion: 'latest'
},
rules: {
// prettier专注于代码的美观度 (格式化工具)
// 前置:
// 1. 禁用格式化插件 prettier format on save 关闭
// 2. 安装Eslint插件, 并配置保存时自动修复
'prettier/prettier': [
'warn',
{
singleQuote: true, // 单引号
semi: false, // 无分号
printWidth: 80, // 每行宽度至多80字符
trailingComma: 'none', // 不加对象|数组最后逗号
endOfLine: 'auto' // 换行符号不限制(win mac 不一致)
}
],
// ESLint关注于规范, 如果不符合规范,报错
'vue/multi-word-component-names': [
'warn',
{
ignores: ['index'] // vue组件名称多单词组成(忽略index.vue)
}
],
'vue/no-setup-props-destructure': ['off'], // 关闭 props 解构的校验 (props解构丢失响应式)
// 添加未定义变量错误提示,create-vue@3.6.3 关闭,这里加上是为了支持下一个章节演示。
'no-undef': 'error'
}
}
前提条件:安装Eslint插件且配置保存修复,不要开启默认的自动保存格式化,把Prettier - Code formatter插件禁用。
settings.json
{
"workbench.colorTheme": "Default Light+",
"[html]": {
"editor.defaultFormatter": "vscode.html-language-features"
},
"emmet.triggerExpansionOnTab": true,
// "[vue]": {
// "editor.defaultFormatter": "Vue.volar"
// },
// 当保存的时候,eslint自动帮我们修复错误
"editor.codeActionsOnSave": {
"source.fixAll": "explicit"
},
// 保存代码,不自动格式化
"editor.formatOnSave": false
}
五、配置代码检查工作流
1. 提交前做代码检查
1. 打开git bash终端,初始化git仓库,执行 git init 即可
2. 初始化husky工具配置,执行 pnpm dlx husky-init && pnpm install 即可
https://typicode.github.io/husky/
3. 修改 .husky/pre-commit文件
#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"
pnpm lint
4. 提交测试
5. 问题:pnpm lint 是全量检查,耗时问题,历史问题
2. 暂存区eslint校验
1. 安装lint-staged包
pnpm i lint-staged -D
2. package.json配置lint-staged命令
{
······
"prepare": "husky install",
"lint-staged": "lint-staged"
},
······
"devDependencies": {
······
},
"lint-staged": {
"*.{js,ts,vue}": [
"eslint --fix"
]
}
}
3. .husky/pre-commit文件修改
#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"
pnpm lint-staged
六、目录调整
默认生成的目录结构不满足我们的开发需求,所以这里需要做一些自定义改动。
主要是以下工作:
1. 删除一些初始化的默认文件
清空assets、components、store、views文件夹下的内容;
2. 修改剩余代码内容
①router/index.js
import { createRouter, createWebHistory } from 'vue-router'
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes: []
})
export default router
②App.vue
<script setup></script>
<template>
<div>我是App</div>
</template>
<style scoped></style>
③main.js
import { createApp } from 'vue'
import { createPinia } from 'pinia'
import App from './App.vue'
import router from './router'
const app = createApp(App)
app.use(createPinia())
app.use(router)
app.mount('#app')
3. 新增调整我们需要的目录结构
在src下新增utils和api文件夹。
4. 拷贝全局样式和图片,安装 sass预处理器 支持
pnpm add sass -D
5. 启动项目
pnpm dev
七、vue-router4路由代码解析
1. 路由初始化
1. 创建路由实例由 createRouter 实现
2. 路由模式
- ①history模式使用createWebHistory()
- ②hash模式使用createWebHashHistory()
- ③参数是基础路径,默认/
Vite官网:环境变量和模式 | Vite 官方中文文档
八、引入Element Plus组件库
1. 按需引入Element Plus
1. 安装
pnpm add element-plus
2. 配置按需导入
官方文档:https://element-plus.org/zh-CN/guide/quickstart.html
①首先,安装unplugin-vue-components
和 unplugin-auto-import
这两款插件
pnpm add -D unplugin-vue-components unplugin-auto-import
②修改配置文件:vite.config.js
import { fileURLToPath, URL } from 'node:url'
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
// https://vitejs.dev/config/
export default defineConfig({
// base: '/jd',
plugins: [
vue(),
AutoImport({
resolvers: [ElementPlusResolver()]
}),
Components({
resolvers: [ElementPlusResolver()]
})
],
resolve: {
alias: {
'@': fileURLToPath(new URL('./src', import.meta.url))
}
}
})
3. 直接使用组件(组件内自动按需导入)
components/TestDemo.vue
<template>
<div>我是test测试的组件</div>
</template>
App.vue
<script setup>
// 在Vue3 CompositionAPI中
// 1. 获取路由对象router useRouter
// const router = useRouter
// 2. 获取路由参数 route useRoute
// const route = useRoute()
import { useRouter, useRoute } from 'vue-router'
const router = useRouter()
const route = useRoute()
const goList = () => {
// this.$router.push('/list') // this指向undefined
console.log(router, route)
router.push('/list')
}
</script>
<template>
我是App
<!-- 组件名要符合规范才可以自动按需导入 -->
<test-demo></test-demo>
<el-button @click="$router.push('/home')">跳首页</el-button>
<el-button @click="goList">跳列表页</el-button>
<el-button type="primary">Primary</el-button>
<el-button type="success">Success</el-button>
</template>
<style scoped></style>
4. 彩蛋:默认components下的文件也会被自动注册
九、Pinia构建仓库和持久化
(1)持久化
①src/store/user.js
import { defineStore } from 'pinia'
import { ref } from 'vue'
// 用户模块 token setToken removeToken
export const useUserStore = defineStore('big-user', () => {
const token = ref('')
const setToken = (newToken) => {
token.value = newToken
}
const removeToken = () => {
token.value = ''
}
return {
token,
setToken,
removeToken
}
})
②App.vue
<script setup>
// 在Vue3 CompositionAPI中
// 1. 获取路由对象router useRouter
// const router = useRouter
// 2. 获取路由参数 route useRoute
// const route = useRoute()
import { useRouter, useRoute } from 'vue-router'
const router = useRouter()
const route = useRoute()
const goList = () => {
// this.$router.push('/list') // this指向undefined
console.log(router, route)
router.push('/list')
}
import { useUserStore } from './stores/user'
const userStore = useUserStore()
</script>
<template>
<div>
我是App
<!-- 组件名要符合规范才可以自动按需导入 -->
<test-demo></test-demo>
<el-button @click="$router.push('/home')">跳首页</el-button>
<el-button @click="goList">跳列表页</el-button>
<el-button type="primary">Primary</el-button>
<el-button type="success">Success</el-button>
<p>{{ userStore.token }}</p>
<el-button @click="userStore.setToken('Bearersidhfklamvj')">
登录
</el-button>
<el-button @click="userStore.removeToken('')">退出</el-button>
</div>
</template>
<style scoped></style>
③持久化
pnpm add pinia-plugin-persistedstate -D
④使用main.js
import { createApp } from 'vue'
import { createPinia } from 'pinia'
import persist from 'pinia-plugin-persistedstate'
import App from './App.vue'
import router from './router'
import '@/assets/main.scss'
const app = createApp(App)
app.use(router)
app.use(createPinia().use(persist))
app.mount('#app')
⑤在store/user.js中添加第三个参数persist
import { defineStore } from 'pinia'
import { ref } from 'vue'
// 用户模块 token setToken removeToken
export const useUserStore = defineStore(
'big-user',
() => {
const token = ref('')
const setToken = (newToken) => {
token.value = newToken
}
const removeToken = () => {
token.value = ''
}
return {
token,
setToken,
removeToken
}
},
{
persist: true
}
)
(2)Pinia仓库统一管理
目标:pinia独立维护,仓库统一导出
①src/stores/index.js
import { createPinia } from 'pinia'
import persist from 'pinia-plugin-persistedstate'
const pinia = createPinia()
pinia.use(persist)
export default pinia
// import { useUserStore } from './modules/user'
// import { useCounterStore } from './modules/counter'
// export { useUserStore, useCounterStore }
export * from './modules/user' // 接收user模块的所有按需导出
export * from './modules/counter'
②main.js
import { createApp } from 'vue'
import pinia from '@/stores/index'
import App from './App.vue'
import router from './router'
import '@/assets/main.scss'
const app = createApp(App)
app.use(router)
app.use(pinia)
app.mount('#app')
③App.vue
<script setup>
// 在Vue3 CompositionAPI中
// 1. 获取路由对象router useRouter
// const router = useRouter
// 2. 获取路由参数 route useRoute
// const route = useRoute()
import { useRouter, useRoute } from 'vue-router'
import { useUserStore, useCounterStore } from './stores'
const router = useRouter()
const route = useRoute()
const goList = () => {
// this.$router.push('/list') // this指向undefined
console.log(router, route)
router.push('/list')
}
const userStore = useUserStore()
const counterStore = useCounterStore()
</script>
<template>
<div>
我是App
<!-- 组件名要符合规范才可以自动按需导入 -->
<test-demo></test-demo>
<el-button @click="$router.push('/home')">跳首页</el-button>
<el-button @click="goList">跳列表页</el-button>
<el-button type="primary">Primary</el-button>
<el-button type="success">Success</el-button>
<p>{{ userStore.token }}</p>
<el-button @click="userStore.setToken('Bearersidhfklamvj')">
登录
</el-button>
<el-button @click="userStore.removeToken('')">退出</el-button>
<p>{{ counterStore.count }}</p>
<el-button @click="counterStore.sub(1)">-</el-button>
<el-button @click="counterStore.add(1)">+</el-button>
</div>
</template>
<style scoped></style>
十、数据交互 - 请求工具设计
①安装axios
②请求配置
拦截器 | Axios中文文档 | Axios中文网
src/utils/request.js
import axios from 'axios'
import { useUserStore } from '@/stores'
import { ElMessage } from 'element-plus'
import router from '@/router'
const baseURL = 'http://big-event-vue-api-t.itheima.net'
const instance = axios.create({
// TODO 1. 基础地址,超时时间
baseURL,
timeout: 10000
})
// 请求拦截器
instance.interceptors.request.use(
(config) => {
// TODO 2. 携带token
const useStore = useUserStore()
if (useStore.token) {
config.headers.Authorization = useStore.token
}
return config
},
(err) => Promise.reject(err)
)
// 响应拦截器
instance.interceptors.response.use(
(res) => {
// TODO 4. 摘取核心响应数据
if (res.data.code === 0) {
return res
}
// TODO 3. 处理业务失败
// 处理业务失败, 给错误提示,抛出错误
ElMessage.error(res.data.message || '服务异常')
return Promise.reject(res.data)
},
(err) => {
// TODO 5. 处理401错误
// 错误的特殊情况 => 401 权限不足 或 token 过期 => 拦截到登录
if (err.response?.status === 401) {
router.push('/login')
}
// 错误的默认情况 => 只要给提示
ElMessage.error(err.response.data.message || '服务异常')
return Promise.reject(err)
}
)
// 默认导出
export default instance
// 按需导出
export { baseURL }
十一、整体路由设计
一级路由:登录、架子
二级路由:文章分类、文章管理、基本资料、更换头像、重置密码
router/index.js
import { createRouter, createWebHistory } from 'vue-router'
// createRouter 创建路由实例
// 1. createWebHistory 配置history模式 -> 地址栏不带#
// createWebHashHistory 配置hash模式 -> 地址栏带#
// import.meta.env.BASE_URL vite中的环境变量,就是vite.config.js中的base配置项
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes: [
{ path: '/login', component: () => import('@/views/login/LoginPage.vue') }, // 登录页
{
path: '/',
component: () => import('@/views/layout/LayoutContainer.vue'),
redirect: '/article/manage',
children: [
{
path: '/article/manage',
component: () => import('@/views/article/ArticleManage.vue')
},
{
path: '/article/channel',
component: () => import('@/views/article/ArticleChannel.vue')
},
{
path: '/user/profile',
component: () => import('@/views/user/UserProfile.vue')
},
{
path: '/user/avatar',
component: () => import('@/views/user/UserAvatar.vue')
},
{
path: '/user/password',
component: () => import('@/views/user/UserPassword.vue')
}
]
}
]
})
export default router
App.vue
<script setup>
// 在Vue3 CompositionAPI中
// 1. 获取路由对象router useRouter
// const router = useRouter
// 2. 获取路由参数 route useRoute
// const route = useRoute()
import { useRouter, useRoute } from 'vue-router'
import { useUserStore, useCounterStore } from './stores'
const router = useRouter()
const route = useRoute()
const goList = () => {
// this.$router.push('/list') // this指向undefined
console.log(router, route)
router.push('/list')
}
const userStore = useUserStore()
const counterStore = useCounterStore()
</script>
<template>
<div>
<hr />
<router-view></router-view>
<hr />
<hr />
<hr />
我是App
<!-- 组件名要符合规范才可以自动按需导入 -->
<test-demo></test-demo>
<el-button @click="$router.push('/home')">跳首页</el-button>
<el-button @click="goList">跳列表页</el-button>
<el-button type="primary">Primary</el-button>
<el-button type="success">Success</el-button>
<p>{{ userStore.token }}</p>
<el-button @click="userStore.setToken('Bearersidhfklamvj')">
登录
</el-button>
<el-button @click="userStore.removeToken('')">退出</el-button>
<p>{{ counterStore.count }}</p>
<el-button @click="counterStore.sub(1)">-</el-button>
<el-button @click="counterStore.add(1)">+</el-button>
</div>
</template>
<style scoped></style>
在views下新建以下内容
十二、登录注册页面【Element-plus表单 & 表单校验】
功能需求说明:
1. 注册登录 静态结构 & 基本切换
2. 注册功能(校验 + 注册)
3. 登录功能(校验 + 登录 + 存token)
1. 注册登录 静态结构 & 基本切换

import { ref } from 'vue'
const isRegister = ref(true)
const form = ref()
// 整个的用于提交的form数据对象
const formModel = ref({
username: '',
password: '',
repassword: ''
})
// 整个表单的校验规则
// 1. 非空校验 required: true message消息提示,trigger触发校验的时机:blur change
// 2. 长度校验 min:xxx, max:xxx
// 3. 正则校验 pattern: 正则规则 \S:非空字符
// 4. 自定义校验 => 自己写逻辑校验(校验函数)
// validator: (rule, value, callback)
// (1)rule: 当前校验规则的相关信息
// (2)value: 所校验的表单元素目前的表单值
// (3)callback 无论成功还是失败,都需要callback回调
// - callback()校验成功
// - callback(new Error(错误信息))校验失败

2. 登录访问拦截
导航守卫 | Vue Router
src/router/index.js
import { useUserStore } from '@/stores'
// 添加登录访问拦截 => 默认是直接放行的
// 根据返回值决定,是放行还是拦截
// 返回值:
// 1. undefined / true 直接放行
// 2. false 拦截回from的地址页面
// 3. 具体路径或路径对象 拦截到对应的地址
// '/login' { name: 'login' }
router.beforeEach(async (to) => {
// 如果没有token,且访问的是非登录页,拦截到登录,其他情况正常放行
const userStore = useUserStore()
if (!userStore.token && to.path !== '/login') return '/login'
// return true
})
3. 用户基本信息获取&渲染
①src/api/user.js
// 获取用户基本信息
export const userGetInfoService = () => request.get('/my/userinfo')

十四、文章分类页面 - 【element-plus表格】
功能需求说明:
1. 基本架子 - PageContainer封装
2. 文章分类渲染 & loading处理
3. 文章分类添加编辑【element-plus弹层】
4. 文章分类删除
1. 基本架子 - PageContainer封装
①src/components/PageContainer.vue
<script setup>
defineProps({
title: {
required: true,
type: String
}
})
</script>
<template>
<el-card class="page-container">
<template #header>
<div class="header">
<span>{{ title }}</span>
<div class="extra">
<!-- 具名插槽,定制额外的按钮 -->
<slot name="extra"></slot>
</div>
</div>

min-height: 100%;
box-sizing: border-box;
.header {
display: flex;
align-items: center;
justify-content: space-between;
}
}
</style>
②src/views/article/ArticleChannel.vue
<template>
<page-container title="文章分类">
<template #extra>
<el-button type="primary">添加分类</el-button>
</template>
主体部分,是表格
</page-container>
</template>
<style lang="scss" scoped></style>
③src/views/article/ArticleManage.vue
<template>
<page-container title="文章管理">
<template #extra>
<el-button type="primary">添加文章</el-button>
</template>
主体部分,是表格 + 分页
</page-container>
</template>
<style lang="scss" scoped></style>
2. 文章分类渲染 & loading处理
(1)封装API - 请求获取表格数据
①新建src/api/article.js,封装接口获取频道列表的接口
import request from '@/utils/request'
// 获取文章分类
export const artGetChannelsService = () => request.get('/my/cate/list')
②页面中调用接口,获取数据存储 -> src/views/article/ArticleChannel.vue
这里默认应该是没有数据的,可以在在线演示系统,登录自己的账号添加数据:黑马程序员-大事件
<script setup>
import { ref } from 'vue'
import { artGetChannelsService } from '../../api/article'
const channelList = ref([])
const getChannelList = async () => {
const res = await artGetChannelsService()
channelList.value = res.data.data
// console.log(channelList.value)
}
// 一进页面,直接调用
getChannelList()
</script>
(2)el-table表格动态渲染
src/views/article/ArticleChannel.vue
<script setup>
import { ref } from 'vue'
import { artGetChannelsService } from '../../api/article'
import { Edit, Delete } from '@element-plus/icons-vue'
const channelList = ref([])
const loading = ref(false)
const getChannelList = async () => {
// 发请求前开启loading效果
loading.value = true
const res = await artGetChannelsService()
channelList.value = res.data.data
// console.log(channelList.value)
// 请求结束后关闭loading效果
loading.value = false
}
// 一进页面,直接调用
getChannelList()
const onEditChannel = (row, $index) => {
console.log(row, $index)
}
const onDelChannel = (row, $index) => {
console.log(row, $index)
}
</script>
<template>
<page-container title="文章分类">
<template #extra>
<el-button type="primary">添加分类</el-button>
</template>
<!-- v-loading绑定loading变量 -->
<el-table v-loading="loading" :data="channelList" style="width: 100%">
<el-table-column type="index" label="序号" width="100"></el-table-column>
<el-table-column prop="cate_name" label="分类名称"></el-table-column>
<el-table-column prop="cate_alias" label="分类别名"></el-table-column>
<el-table-column prop="" label="操作" width="150">
<!-- row 就是channelList的一项,$index是下标 -->
<template #default="{ row, $index }">
<el-button
:icon="Edit"
circle
plain
type="primary"
@click="onEditChannel(row, $index)"
></el-button>
<el-button
:icon="Delete"
circle
plain
type="danger"
@click="onDelChannel(row, $index)"
></el-button>
</template>
</el-table-column>
<!-- 插槽 -->
<template #empty>
<el-empty description="没有数据" />
</template>
</el-table>
</page-container>
</template>
<style lang="scss" scoped></style>
3. 文章分类添加编辑【element-plus弹层】
①封装组件 src/views/article/components/ChannelEdit.vue
<script setup>
import { ref } from 'vue'
const dialogVisible = ref(false)
// 组件对外暴露一个方法open,基于open传来的参数,区分添加还是编辑
// open({}) => 表单无需渲染,说明是添加
// open({id, cate_name, ...}) => 表单需要渲染(数据回显),说明是编辑
// open调用后,可以打开弹窗
const open = (row) => {
console.log(row)
dialogVisible.value = true
}
// 向外暴露方法
defineExpose({
open
})
</script>
<template>
<el-dialog v-model="dialogVisible" title="添加弹层" width="30%">
<span>我是内容部分</span>
<template #footer>
<div class="dialog-footer">
<el-button @click="dialogVisible = false">取消</el-button>
<el-button type="primary" @click="dialogVisible = false">
确认
</el-button>
</div>
</template>
</el-dialog>
</template>
②通过ref绑定,点击调用方法显示弹窗
src/views/article/ArticleChannel.vue
<script setup>
import { ref } from 'vue'
import { artGetChannelsService } from '../../api/article'
import { Edit, Delete } from '@element-plus/icons-vue'
import ChannelEdit from './components/ChannelEdit.vue'
const channelList = ref([])
const loading = ref(false)
const dialog = ref()
const getChannelList = async () => {
// 发请求前开启loading效果
loading.value = true
const res = await artGetChannelsService()
channelList.value = res.data.data
// console.log(channelList.value)
// 请求结束后关闭loading效果
loading.value = false
}
// 一进页面,直接调用
getChannelList()
// 编辑
const onEditChannel = (row) => {
dialog.value.open(row)
}
const onDelChannel = (row, $index) => {
console.log(row, $index)
}
// 添加
const onAddChannel = () => {
// 显示弹层
dialog.value.open({})
}
</script>
<template>
<page-container title="文章分类">
<template #extra>
<el-button type="primary" @click="onAddChannel">添加分类</el-button>
</template>
<el-table v-loading="loading" :data="channelList" style="width: 100%">
<el-table-column type="index" label="序号" width="100"></el-table-column>
<el-table-column prop="cate_name" label="分类名称"></el-table-column>
<el-table-column prop="cate_alias" label="分类别名"></el-table-column>
<el-table-column prop="" label="操作" width="150">
<!-- row 就是channelList的一项,$index是下标 -->
<template #default="{ row, $index }">
<el-button
:icon="Edit"
circle
plain
type="primary"
@click="onEditChannel(row, $index)"
></el-button>
<el-button
:icon="Delete"
circle
plain
type="danger"
@click="onDelChannel(row, $index)"
></el-button>
</template>
</el-table-column>
<!-- 插槽 -->
<template #empty>
<el-empty description="没有数据" />
</template>
</el-table>
<ChannelEdit ref="dialog"></ChannelEdit>
</page-container>
</template>
<style lang="scss" scoped></style>
③准备弹层表单
准备表单和校验规则,编辑时回显
src/views/article/components/ChannelEdit.vue
<script setup>
import { ref } from 'vue'
const dialogVisible = ref(false)
const formModel = ref({
cate_name: '',
cate_alias: ''
})
const rules = {
cate_name: [
{ required: true, message: '请输入分类名称', trigger: 'blur' },
{
pattern: /^\S{1,10}$/,
message: '分类名必须是1-10位的非空字符',
trigger: 'blur'
}
],
cate_alias: [
{ required: true, message: '请输入分类别名', trigger: 'blur' },
{
pattern: /^[a-zA-Z0-9]{1,15}$/,
message: '分类别名必须是1-15位的字母或数字',
trigger: 'blur'
}
]
}
// 组件对外暴露一个方法open,基于open传来的参数,区分添加还是编辑
// open({}) => 表单无需渲染,说明是添加
// open({id, cate_name, ...}) => 表单需要渲染(数据回显),说明是编辑
// open调用后,可以打开弹窗
const open = (row) => {
// console.log(row)
dialogVisible.value = true
formModel.value = { ...row } // 添加-> 重置表单内容,编辑 -> 存储了需要回显的数据
}
// 向外暴露方法
defineExpose({
open
})
</script>
<template>
<el-dialog
v-model="dialogVisible"
:title="formModel.id ? '编辑分类' : '添加分类'"
width="30%"
>
<el-form
:model="formModel"
:rules="rules"
label-width="100px"
style="padding-right: 30px"
>
<el-form-item prop="cate_name" label="分类名称">
<el-input
v-model="formModel.cate_name"
placeholder="请输入分类名称"
></el-input>
</el-form-item>
<el-form-item prop="cate_alias" label="分类别名">
<el-input
v-model="formModel.cate_alias"
placeholder="请输入分类别名"
></el-input>
</el-form-item>
</el-form>
<template #footer>
<div class="dialog-footer">
<el-button @click="dialogVisible = false">取消</el-button>
<el-button type="primary" @click="dialogVisible = false">
确认
</el-button>
</div>
</template>
</el-dialog>
</template>
④确认提交 -> src/api/article.js,封装请求API
// 添加文章分类
export const artAddChannelsService = (data) =>
request.post('/my/cate/add', data)
// 编辑文章分类
export const artEditChannelsService = (data) =>
request.put('/my/cate/info', data)
⑤页面中校验,判断,提交请求
ChannelEdit.vue
import { artEditChannelsService, artAddChannelsService } from '@/api/article.js'
const formRef = ref()
const emit = defineEmits(['success'])
const onSubmit = async () => {
// 表单校验
await formRef.value.validate()
const isEdit = formModel.value.id
if (isEdit) {
// 编辑操作
await artEditChannelsService(formModel.value)
ElMessage.success('修改成功')
} else {
// 添加操作
await artAddChannelsService(formModel.value)
ElMessage.success('添加成功')
}
// 关闭弹层
dialogVisible.value = false
// 子传父
emit('success')
}
⑥父组件监听success事件
<channel-edit ref="dialog" @success="onSuccess"></channel-edit>
const onSuccess = () => {
getChannelList()
}
4. 文章分类删除
①src/api/article.js
// 删除文章分类
export const artDelChannelsService = (id) =>
request.delete('/my/cate/del', {
params: { id }
})
②ArticleChannel.vue
// 删除
const onDelChannel = async (row) => {
await ElMessageBox.confirm('你确认要删除该分类么', '温馨提示', {
type: 'warning',
confirmButtonText: '确认',
cancelButtonText: '取消'
})
await artDelChannelsService(row.id)
ElMessage.success('删除成功')
getChannelList()
}
十五、文章管理页面 - [element-plus进阶]
功能需求说明:
1. 文章列表渲染(带搜索 & 带分页)
2. 添加文章(抽屉 & 文件上传 & 富文本)
3. 编辑文章(共用抽屉)
4. 删除文章
1. 文章列表渲染(带搜索 & 带分页)
(1)文章列表渲染及基本架子搭建
①搜索表单
src/views/article/ArticleManage.vue
<template>
<page-container title="文章管理">

(2)中英国际化处理
全局配置 | Element Plus
默认是英文的,由于这里不涉及切换,所以在App.vue中直接导入设置成中文集合
App.vue
<script setup>
import zhCn from 'element-plus/es/locale/lang/zh-cn.mjs'
</script>
<template>
<!-- 路由出口 -->
<el-config-provider :locale="zhCn">
<router-view></router-view>
</el-config-provider>
</template>
<style scoped></style>
(3)文章分类选择
①新建src/views/article/components/ChannelSelect.vue
<script setup>
import { artGetChannelsService } from '@/api/article.js'
import { ref } from 'vue'
defineProps({
modelValue: {
type: [Number, String]
}
})
const emit = defineEmits(['update:modelValue'])
const channelList = ref([])
const getChannelList = async () => {
const res = await artGetChannelsService()
channelList.value = res.data.data
console.log(channelList.value)
}
// 一进页面就调用
getChannelList()
</script>
<template>
<el-select
:modelValue="modelValue"
@update:modelValue="emit('update:modelValue', $event)"
placeholder="请选择"
size="large"
style="width: 240px"

<!-- label是展示给用户看的,value是收集起来提交给后台的 -->
<el-option
v-for="channel in channelList"
:key="channel.id"
:label="channel.cate_name"
:value="channel.id"
></el-option>
</el-select>
</template>
②页面中导入渲染 - src/views/article/ArticleManage.vue
<script setup>
import { Delete, Edit } from '@element-plus/icons-vue'
import { ref } from 'vue'
import ChannelSelect from './components/ChannelSelect.vue'
// 假数据
const articleList = ref([
{
id: 5961,

(4)封装API接口,请求渲染
①src/api/article.js封装接口
// 文章:
// 获取文章列表
export const artGetListService = (params) =>
request.get('/my/article/list', {
params
})
②ArticleMange.vue页面中调用保存数据
import { artGetListService } from '@/api/article.js'
// 文章列表
const articleList = ref([])
// 总条数
const total = ref(0)
// 基于params参数,获取文章列表
const getArticleList = async () => {
const res = await artGetListService(params.value)
articleList.value = res.data.data
total.value = res.data.total
}
// 一进页面就调用
getArticleList()
③新建src/utils/format.js封装格式化日期函数
import { dayjs } from 'element-plus'
export const formatTime = (time) => dayjs(time).format('YYYY年MM月DD日')
④ArticleMange.vue中调用
import { formatTime } from '@/utils/format.js'
<el-table-column label="发表时间" prop="pub_date">
<template #default="{ row }">
<!-- 格式化时间 -->
{{ formatTime(row.pub_date) }}
</template>
</el-table-column>
(5)分页渲染[element-plus分页]
Pagination 分页 | Element Plus
①ArticleManage.vue
<script setup>
import { Delete, Edit } from '@element-plus/icons-vue'
import { ref } from 'vue'
import ChannelSelect from './components/ChannelSelect.vue'
import { artGetListService } from '@/api/article.js'
import { formatTime } from '@/utils/format.js'
// ······
// 处理分页
const onSizeChange = (size) => {
// console.log('当前每页条数', size)
// 只要是每页页数变化了,那么原本正在访问的当前页意义不大了,数据大概率已经不在原来那一页了
// 重新从第一页开始渲染
params.value.pagenum = 1
params.value.pagesize = size
// 基于最新的当前页和每页条数,渲染数据
getArticleList()
}
const onCurrentChange = (page) => {
// console.log('当前每页条数', page)
params.value.pagenum = page
// 基于最新的当前页,渲染数据
getArticleList()
}
</script>
<template>
<page-container title="文章管理">
<template #extra>
<el-button type="primary">添加文章</el-button>
</template>
<!-- 表单区域 -->
<el-form inline>
// ······
</el-form>
<!-- 表格区域 -->
<el-table :data="articleList" style="width: 100%">
// ······
</el-table>
<!-- 分页区 -->
<el-pagination
v-model:current-page="params.pagenum"
v-model:page-size="params.pagesize"
:page-sizes="[2, 3, 5, 10]"
:background="true"
layout="jumper, total, sizes, prev, pager, next"
:total="total"
@size-change="onSizeChange"
@current-change="onCurrentChange"
style="margin-top: 20px; justify-content: flex-end"
/>
</page-container>
</template>
<style lang="scss" scoped></style>
(6)添加loading效果
①准备数据
const loading = ref(false)
②el-table上面绑定
<el-table :data="articleList" v-loading="loading" style="width: 100%">
③发送请求添加loading
// 基于params参数,获取文章列表
const getArticleList = async () => {
loading.value = true
const res = await artGetListService(params.value)
articleList.value = res.data.data
total.value = res.data.total
loading.value = false
}
(7)搜索和重置功能
①注册事件
<el-form-item>
<el-button @click="onSearch" type="primary">搜索</el-button>
<el-button @click="onReset">重置</el-button>
</el-form-item>
②绑定处理
// 搜索逻辑 => 按照最新的条件,重新检索,从第一页开始展示
const onSearch = () => {
params.value.pagenum = 1 // 重置页面
getArticleList()
}
// 重置逻辑 => 将筛选条件清空,重新检索,从第一页开始展示
const onReset = () => {
params.value.pagenum = 1 // 重置页面
params.value.cate_id = ''
params.value.state = ''
getArticleList()
}
2. 添加文章(抽屉 & 文件上传 & 富文本)
(1)点击显示抽屉
①准备数据
import { ref } from 'vue'
const visibleDrawer = ref(false)
②准备抽屉容器
<!-- 抽屉区 -->
<el-drawer
v-model="visibleDrawer"
title="大标题"
direction="rtl"
size="50%"
>
<span>Hi there!</span>
</el-drawer>
③点击修改布尔值,显示抽屉
<el-button type="primary" @click="onAddArticle">发布文章</el-button>
const visibleDrawer = ref(false)
const onAddArticle = () => {
visibleDrawer.value = true
}
(2)封装抽屉组件ArticleEdit
添加 和 编辑,可以共用一个抽屉,所以可以将抽屉封装成一个组件。
①封装组件src/views/article/components/ArticleEdit.vue
<script setup>
import { ref } from 'vue'
// 控制抽屉的显示隐藏
const visibleDrawer = ref(false)
// 组件对外暴露一个方法open,基于open传来的参数,区分添加还是编辑
// open({}) => 表单无需渲染,说明是添加
// open({id, ..., ...}) => 表单需要渲染(数据回显),说明是编辑
// open调用后,可以打开弹窗
const open = (row) => {
visibleDrawer.value = true // 显示抽屉
console.log(row)
}
// 向外暴露方法
defineExpose({
open
})
</script>
<template>
<!-- 抽屉区 -->
<el-drawer v-model="visibleDrawer" title="大标题" direction="rtl" size="50%">
<span>Hi, there!</span>
</el-drawer>
</template>
②通过ref进行绑定
const articleEditRef = ref()
<!-- 抽屉区域 -->
<article-edit ref="articleEditRef"></article-edit>
③点击调用方法显示抽屉
// 添加逻辑
const onAddArticle = () => {
articleEditRef.value.open({})
}
// 编辑
const onEditArticle = (row) => {
// console.log(row)
articleEditRef.value.open(row)
}
(3)完善抽屉表单结构
①准备数据
// 默认数据
const defaultForm = {
title: '', // 标题
cate_id: '', // 分类id
cover_img: '', // 封面图片 file对象
content: '', // string内容
state: '' // 状态
}
// 准备数据
const formModel = ref({
...defaultForm
})
// 组件对外暴露一个方法open,基于open传来的参数,区分添加还是编辑
// open({}) => 表单无需渲染,说明是添加
// open({id, ..., ...}) => 表单需要渲染(数据回显),说明是编辑
// open调用后,可以打开弹窗
const open = (row) => {
visibleDrawer.value = true // 显示抽屉
if (row.id) {
// 需要基于row.id发送请求,获取编辑对应的详情数据,进行回显
console.log('编辑回显')
} else {
formModel.value = { ...defaultForm } // 基于默认的数据,重置form数据
console.log('添加')
}
console.log(row)
}
②准备form表单结构
import ChannelSelect from './ChannelSelect.vue'
<template>
<el-drawer
v-model="visibleDrawer"
:title="formModel.id ? '编辑文章' : '添加文章'"
direction="rtl"
size="50%"
>
<!-- 发表文章表单 -->
<el-form :model="formModel" ref="formRef" label-width="100px">
<el-form-item label="文章标题" prop="title">
<el-input v-model="formModel.title" placeholder="请输入标题"></el-input>
</el-form-item>
<el-form-item label="文章分类" prop="cate_id">
<channel-select
v-model="formModel.cate_id"
width="100%"
></channel-select>
</el-form-item>
<el-form-item label="文章封面" prop="cover_img"> 文件上传 </el-form-item>
<el-form-item label="文章内容" prop="content">
<div class="editor">富文本编辑器</div>
</el-form-item>
<el-form-item>
<el-button type="primary">发布</el-button>
<el-button type="info">草稿</el-button>
</el-form-item>
</el-form>
</el-drawer>
</template>
③扩展下拉菜单width props
src/views/article/components/ChannelSelect.vue
<script setup>
import { artGetChannelsService } from '@/api/article.js'
import { ref } from 'vue'
defineProps({
modelValue: {
type: [Number, String]
},
width: {
type: String
}
})
// ......
</script>
<template>
<el-select
:modelValue="modelValue"
@update:modelValue="emit('update:modelValue', $event)"
placeholder="请选择"
size="large"
:style="{ width }"
>
<!-- ...... -->
</el-select>
</template>
(4)上传文件9lement-plus - 文件预览]

}
}
</style>
3. 编辑文章(共用抽屉)
(1)富文本编辑器[vue-quill]
官网地址:Introduction | VueQuill
①安装
pnpm add @vueup/vue-quill@latest
②注册成局部组件
import { QuillEditor } from '@vueup/vue-quill'
import '@vueup/vue-quill/dist/vue-quill.snow.css'
③页面中使用绑定
<div class="editor">
<quill-editor
theme="snow"
v-model:content="formModel.content"
contentType="html"
>
</quill-editor>
</div>
④样式美化
.editor {
width: 100%;
:deep(.ql-editor) {
min-height: 200px;
}
}
(2)添加文章功能
①封装添加接口 - src/api/article.js
// 文章:添加文章
// 注意:data需要是一个formData格式的对象
export const artPublishService = (data) => request.post('/my/article/add', data)
②注册点击事件调用
ArticleEdit.vue
<el-form-item>
<el-button @click="onPublish('已发布')" type="primary">发布</el-button>
<el-button @click="onPublish('草稿')" type="info">草稿</el-button>
</el-form-item>
// 发布文章
const emit = defineEmits(['success'])
const onPublish = async (state) => {
// 将已发布还是草稿状态,存入 state
formModel.value.state = state
// 转换 formData 数据
const fd = new FormData()
for (let key in formModel.value) {
fd.append(key, formModel.value[key])
}
if (formModel.value.id) {
console.log('编辑操作')
} else {
// 添加请求
await artPublishService(fd)
ElMessage.success('添加成功')
visibleDrawer.value = false
emit('success', 'add')
}
}
③父组件监听事件,重新渲染
ArticleManage.vue
<!-- 抽屉区域 -->
<article-edit ref="articleEditRef" @success="onSuccess"></article-edit>
// 添加或者编辑 成功的回调
const onSuccess = (type) => {
if (type === 'add') {
// 如果是添加,需跳转渲染最后一页,编辑直接渲染当前页
const lastPage = Math.ceil((total.value + 1) / params.value.pagesize)
// 更新成最大页码数,再渲染
params.value.pagenum = lastPage
}
getArticleList()
}
④添加完成后的内容重置 - ArticleEdit.vue
Methods | VueQuill (vueup.github.io)
const editorRef = ref()
const open = (row) => {
visibleDrawer.value = true // 显示抽屉
if (row.id) {
// 需要基于row.id发送请求,获取编辑对应的详情数据,进行回显
// console.log('编辑回显')
} else {
formModel.value = { ...defaultForm } // 基于默认的数据,重置form数据
// 这里重置了表单的数据,但是图片上传img地址、富文本编辑器内容,需要手动重置
imgUrl.value = ''
editorRef.value.setHTML('')
}
}
(3)编辑文章回显
如果是编辑操作,一打开抽屉,就需要发送请求,获取数据进行回显
①封装接口,根据id获取数据详情数据
src/api/article.js
// 根据id获取详情数据
export const artGetDetailService = (id) =>
request.get('my/article/info', { params: { id } })
②页面中调用渲染 - ArticleEdit.vue
import { baseURL } from '@/utils/request.js'
const open = async (row) => {
visibleDrawer.value = true // 显示抽屉
if (row.id) {
console.log('编辑回显')
// 需要基于row.id发送请求,获取编辑对应的详情数据,进行回显
const res = await artGetDetailService(row.id)
// console.log(res)
formModel.value = res.data.data
// 图片需要单独处理回显
imgUrl.value = baseURL + formModel.value.cover_img
// 提交给后台,需要的是file格式,将网络图片,转成file格式
// 将网络图片地址 转成file对象,存储起来,将来便于提交
formModel.value.cover_img = await imageUrlToFileObject(
imgUrl.value,
formModel.value.cover_img
)
} else {
// 添加功能
formModel.value = { ...defaultForm } // 基于默认的数据,重置form数据
// 这里重置了表单的数据,但是图片上传img地址、富文本编辑器内容,需要手动重置
imgUrl.value = ''
editorRef.value.setHTML('')
}
}
// 将网络图片地址转换为File对象
async function imageUrlToFileObject(url, fileName) {
try {
// 第一步:使用axios获取网络图片数据
const response = await axios.get(url, { responseType: 'arraybuffer' })
const imageData = response.data
// 第二步:将图片数据转换为Blob对象
const blob = new Blob([imageData], {
type: response.headers['content-type']
})
// 第三步:创建一个新的File对象
const file = new File([blob], fileName, { type: blob.type })
return file
} catch (error) {
console.error('将图片转换为File对象时发生错误:', error)
throw error
}
}
(4)编辑文章功能
①封装编辑接口
src/api/article.js
// 文章:编辑文章
export const artEditService = (data) => request.put('/my/article/info', data)
②提交时调用 - ArticleEdit.vue
// 提交
const onPublish = async (state) => {
// ......
// 发请求
if (formModel.value.id) {
// 编辑操作
// console.log('编辑操作')
await artEditService(fd)
ElMessage.success('修改成功')
visibleDrawer.value = false
emit('success', 'edit')
} else {
// 添加操作
// ......
}
}
4. 删除文章
①封装删除接口 - article.js
// 文章:删除文章
export const artDelService = (id) => {
request.delete('/my/article/info', { params: { id } })
}
②页面中添加确认框调用 - ArticleManage.vue
import { artGetListService, artDelService } from '@/api/article.js'
// 删除
const onDeleteArticle = async (row) => {
await ElMessageBox.confirm('你确认要删除该文章信息吗?', '温馨提示', {
type: 'warning',
confirmButtonText: '确认',
cancelButtonText: '取消'
})
await artDelService(row.id)
ElMessage({ type: 'success', message: '删除成功' })
getArticleList()
}

2. ChatGPT的基本使用(Prompt优化)
AI 互动的过程中,容易出现的问题:
-
AI未能理解问题的核心要点
-
AI的回答过于宽泛 或 过于具体
-
AI提供了错误的信息或观点
-
AI未能提供有价值的建议或解决方案
在识别了问题所在之后,我们可以尝试以下策略来优化我们的Prompt:
-
明确提问:
确保问题表述清晰明确,关键字的准确度,决定了AI 对于需求的理解。
-
细化需求:
将问题拆分成多个小问题,可以帮助AI更具针对性地回答,也利于即时纠错。
-
添加背景信息:
提供有关问题背景的详细信息,也可以给 AI 预设一个角色,将有助于AI生成更具深度和价值的回答。
-
适当引导:
比如:“例如”、“请注意”、“请使用”等,来告诉模型你期望它做什么 或者 不做什么
-
限制范围:
通过限定回答的范围和长度,可以引导AI生成更精炼的回答

(1)基本资料
①封装接口,更新个人信息 - src/api/iser.js
// 更新个人信息
export const userUpdateInfoService = ({ id, nickname, email }) => {
request.put('/my/userinfo', { id, nickname, email })
}
②静态结构 + 校验处理,页面中校验后,封装调用 - src/views/user/UserProfile.vue
<script setup>
import PageContainer from '@/components/PageContainer.vue'
import { ref } from 'vue'
import { useUserStore } from '@/stores'

(2)更换头像
①封装接口 - src/api/user.js
// 更新头像
export const userUpdateAvatarService = (avatar) => {
request.patch('/my/update/avatar', { avatar })
}
②静态结构 ,封装调用 - src/views/user/UserAvatar.vue
<script setup>
import { ref } from 'vue'
import { Plus, Upload } from '@element-plus/icons-vue'
import { useUserStore } from '@/stores'
import { userUpdateAvatarService } from '@/api/user'
const userStore = useUserStore()
const imgUrl = ref(userStore.user.user_pic)
const uploadRef = ref()
const onSelectFile = (uploadFile) => {
// 基于 FileReader 读取图片做预览
const reader = new FileReader()
reader.readAsDataURL(uploadFile.raw)
reader.onload = () => {
imgUrl.value = reader.result
}
}
const onUpdateAvatar = async () => {
// 发送请求更新头像
await userUpdateAvatarService(imgUrl.value)
// userStore 重新渲染
await userStore.getUser()
// 提示用户
ElMessage.success('头像更新成功')
}
</script>
<template>
<page-container title="更换头像">
<el-upload

(3)重置密码
①封装接口 - src/api/user.js
// 重置密码
export const userUpdatePasswordService = ({ old_pwd, new_pwd, re_pwd }) => {
request.patch('/my/updatepwd', { old_pwd, new_pwd, re_pwd })
}
②静态结构 ,封装调用 - src/views/user/UserAvatar.vue

import { useUserStore } from '@/stores'
import { useRouter } from 'vue-router'
const formRef = ref()

old_pwd: '',
new_pwd: '',
re_pwd: ''
})
const checkDifferent = (rule, value, callback) => {
// 校验新密码和原密码不能一样
if (value === pwdForm.value.old_pwd) {
callback(new Error('新密码不能与原密码一样'))
} else {
callback()
}
}
const checkSameAsNewPwd = (rule, value, callback) => {
// 校验确认密码必须和新密码一样
if (value !== pwdForm.value.new_pwd) {
callback(new Error('确认密码必须和新密码一样'))
} else {
callback()
}
}
const rules = ref({

})
const userStore = useUserStore()
const router = useRouter()
const submitForm = async () => {
await formRef.value.validate()
await userUpdatePasswordService(pwdForm.value)
ElMessage.success('密码修改成功')
// 密码修改成功后,退出重新登录
// 清空本地存储的 token 和 个人信息
userStore.setToken('')
userStore.setUser({})
// 拦截登录
router.push('/login')
}
const resetForm = () => {
formRef.value.resetFields()
}
