前言

这里来做文章的增删改查功能，其中涉及到图片上传和vue-quill富文本组件的使用。

---

一、搭建界面

<script setup>
import {Edit,Delete
} from '@element-plus/icons-vue'import { ref,onMounted } from 'vue'
import articleCategoryListService from '@/api/article.js'//文章分类数据模型
const categorys = ref([])onMounted(async() => {let result = await articleCategoryListService();if (result.code == 0) {categorys.value = result.data}
}) //用户搜索时选中的分类id
const categoryId=ref('')//用户搜索时选中的发布状态
const state=ref('')//文章列表数据模型
const articles = ref([{"id": 5,"title": "陕西旅游攻略","content": "兵马俑,华清池,法门寺,华山...爱去哪去哪...","coverImg": "https://big-event-gwd.oss-cn-beijing.aliyuncs.com/9bf1cf5b-1420-4c1b-91ad-e0f4631cbed4.png","state": "草稿","categoryId": 2,"createTime": "2023-09-03 11:55:30","updateTime": "2023-09-03 11:55:30"},{"id": 5,"title": "陕西旅游攻略","content": "兵马俑,华清池,法门寺,华山...爱去哪去哪...","coverImg": "https://big-event-gwd.oss-cn-beijing.aliyuncs.com/9bf1cf5b-1420-4c1b-91ad-e0f4631cbed4.png","state": "草稿","categoryId": 2,"createTime": "2023-09-03 11:55:30","updateTime": "2023-09-03 11:55:30"},{"id": 5,"title": "陕西旅游攻略","content": "兵马俑,华清池,法门寺,华山...爱去哪去哪...","coverImg": "https://big-event-gwd.oss-cn-beijing.aliyuncs.com/9bf1cf5b-1420-4c1b-91ad-e0f4631cbed4.png","state": "草稿","categoryId": 2,"createTime": "2023-09-03 11:55:30","updateTime": "2023-09-03 11:55:30"},
])//分页条数据模型
const pageNum = ref(1)//当前页
const total = ref(20)//总条数
const pageSize = ref(3)//每页条数//当每页条数发生了变化，调用此函数
const onSizeChange = (size) => {pageSize.value = size
}
//当前页码发生变化，调用此函数
const onCurrentChange = (num) => {pageNum.value = num
}
</script>
<template><el-card class="page-container"><template #header><div class="header"><span>文章管理</span><div class="extra"><el-button type="primary">添加文章</el-button></div></div></template><!-- 搜索表单 --><el-form inline><el-form-item label="文章分类："><el-select placeholder="请选择" v-model="categoryId" style="width: 240px"><el-option v-for="c in categorys" :key="c.id" :label="c.categoryName":value="c.id"></el-option></el-select></el-form-item><el-form-item label="发布状态："><el-select placeholder="请选择" v-model="state" style="width: 240px"><el-option label="已发布" value="已发布"></el-option><el-option label="草稿" value="草稿"></el-option></el-select></el-form-item><el-form-item><el-button type="primary">搜索</el-button><el-button>重置</el-button></el-form-item></el-form><!-- 文章列表 --><el-table :data="articles" style="width: 100%"><el-table-column label="文章标题" width="400" prop="title"></el-table-column><el-table-column label="分类" prop="categoryId"></el-table-column><el-table-column label="发表时间" prop="createTime"> </el-table-column><el-table-column label="状态" prop="state"></el-table-column><el-table-column label="操作" width="100"><template #default="{ row }"><el-button :icon="Edit" circle plain type="primary"></el-button><el-button :icon="Delete" circle plain type="danger"></el-button></template></el-table-column><template #empty><el-empty description="没有数据" /></template></el-table><!-- 分页条 --><el-pagination v-model:current-page="pageNum" v-model:page-size="pageSize" :page-sizes="[3, 5 ,10, 15]"layout="jumper, total, sizes, prev, pager, next" background :total="total" @size-change="onSizeChange"@current-change="onCurrentChange" style="margin-top: 20px; justify-content: flex-end" /></el-card>
</template>
<style lang="scss" scoped>
.page-container {min-height: 100%;box-sizing: border-box;.header {display: flex;align-items: center;justify-content: space-between;}
}
</style>

二、加载文章列表

1.界面

<!-- 文章列表 --><el-table :data="articles" style="width: 100%"><el-table-column label="文章标题" width="400" prop="title"></el-table-column><el-table-column label="分类" prop="categoryName"></el-table-column><el-table-column label="发表时间" prop="createTime"> </el-table-column><el-table-column label="状态" prop="state"></el-table-column><el-table-column label="操作" width="100"><template #default="{ row }"><el-button :icon="Edit" circle plain type="primary"></el-button><el-button :icon="Delete" circle plain type="danger"></el-button></template></el-table-column><template #empty><el-empty description="没有数据" /></template></el-table>

2.请求脚本

export const articleListService = (params)=>{return request.get('/article/page',{params:params})
}

3. 加载事件

import { articleListService } from '@/api/article.js'onMounted(async () => {let result = await articleCategoryListService();if (result.code == 0) {categorys.value = result.data}loadArticles()
})
//获取文章列表
const loadArticles = async () => {var params = new URLSearchParams()params.append('pageNum', pageNum.value)params.append('pageSize', pageSize.value)if (categoryId.value) params.append('categoryId', categoryId.value)if (state.value) params.append('state', state.value)const result = await articleListService(params)if (result.code == 0) {total.value = result.data.totalarticles.value = result.data.items}articles.value.forEach(article => {categorys.value.forEach(category => {if (article.categoryId == category.id) {article.categoryName=category.categoryName}});});
}

4. 搜索和重置

<el-form-item><el-button type="primary" @click="loadArticles">搜索</el-button><el-button @click="reset">重置</el-button>
</el-form-item>

//重置
const reset = () => {categoryId.value=''state.value=''loadArticles()
}

5. 分页事件

//当每页条数发生了变化，调用此函数
const onSizeChange = (size) => {pageSize.value = sizeloadArticles()
}
//当前页码发生变化，调用此函数
const onCurrentChange = (num) => {pageNum.value = numloadArticles()
}

三、添加文章

1. 富文本编辑器

1.1 安装

npm install @vueup/vue-quill@latest --save

1.2 导入组件

import { QuillEditor } from '@vueup/vue-quill'
import '@vueup/vue-quill/dist/vue-quill.snow.css'

1.3 使用

<quill-editor theme="snow" v-model:content="articleModel.content"contentType="html">
</quill-editor></div>

1.4 样式美化

.editor {width: 100%;:deep(.ql-editor) {min-height: 200px;}
}

2. 页面搭建

2.1 数据绑定

//添加文章
//控制抽屉是否显示
const visibleDrawer = ref(false)
//添加表单数据模型
const articleModel = ref({title: '',categoryId: '',coverImg: '',content: '',state: ''
})

2.2 界面

<el-button type="primary" @click="visibleDrawer = true">添加文章</el-button><!-- 抽屉 -->
<el-drawer v-model="visibleDrawer" title="添加文章" direction="rtl" size="50%"><!-- 添加文章表单 --><el-form :model="articleModel" label-width="100px"><el-form-item label="文章标题"><el-input v-model="articleModel.title" placeholder="请输入标题"></el-input></el-form-item><el-form-item label="文章分类"><el-select placeholder="请选择" v-model="articleModel.categoryId"><el-option v-for="c in categorys" :key="c.id" :label="c.categoryName" :value="c.id"></el-option></el-select></el-form-item><el-form-item label="文章封面"><el-upload class="avatar-uploader" :auto-upload="false" :show-file-list="false"><img v-if="articleModel.coverImg" :src="articleModel.coverImg" class="avatar" /><el-icon v-else class="avatar-uploader-icon"><Plus /></el-icon></el-upload></el-form-item><el-form-item label="文章内容"><div class="editor"><quill-editor theme="snow" v-model:content="articleModel.content"contentType="html"></quill-editor></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>

3. 图片上传

我这里把文件放到public目录下，方便动态返显图片。

3.1 数据绑定

import {useTokenStore} from '@/stores/token.js';//图片上传
const token=ref('')
const updateBefore=()=>{const tokenStore=useTokenStore()if(tokenStore.getToken()){token.value={'Authorization':'Bearer '+tokenStore.getToken()}}
}
const uploadSuccess=(response)=>{console.log(response)articleModel.value.coverImg='/image/'+response.data
}

3.2 界面

<el-upload class="avatar-uploader" :auto-upload="true" action="/api/file/upload" :name="file" :headers="token" :before-upload="updateBefore" :on-success="uploadSuccess"
:show-file-list="false"><el-image v-if="articleModel.coverImg" :src="articleModel.coverImg" class="avatar" :fit="fit" /><el-icon v-else class="avatar-uploader-icon"><Plus /></el-icon>
</el-upload>

4. 表单校验

4.1 脚本

//添加表单校验
const articleFormRef = ref(null)
const rules = {title: [{ required: true, message: '请输入文章标题', trigger: 'blur' }],categoryId: [{ required: true, message: '请选择文章分类', trigger: 'change' }],coverImg: [{ required: true, message: '请上传文章封面', trigger: 'blur' }],content: [{ required: true, message: '请输入文章内容', trigger: 'blur' }]
}

4.2 表单

<!-- 添加文章表单 -->
<el-form :model="articleModel" label-width="100px" ref="articleFormRef" :rules="rules"><el-form-item label="文章标题" prop="title"><el-input v-model="articleModel.title" placeholder="请输入标题"></el-input></el-form-item><el-form-item label="文章分类" prop="categoryId"><el-select placeholder="请选择文章分类" v-model="articleModel.categoryId"><el-option v-for="c in categorys" :key="c.id" :label="c.categoryName" :value="c.id"></el-option></el-select></el-form-item><el-form-item label="文章封面" prop="coverImg"><el-upload class="avatar-uploader" :auto-upload="true" action="/api/file/upload" :name="file" :headers="token" :before-upload="updateBefore" :on-success="uploadSuccess":show-file-list="false"><el-image v-if="articleModel.coverImg" :src="articleModel.coverImg" class="avatar" :fit="fit" /><el-icon v-else class="avatar-uploader-icon"><Plus /></el-icon></el-upload></el-form-item><el-form-item label="文章内容" prop="content"><div class="editor"><quill-editor theme="snow" v-model:content="articleModel.content"contentType="html" placeholder="请输入文章内容"></quill-editor></div></el-form-item><el-form-item><el-button type="primary" @click="addArticle('已发布')">发布</el-button><el-button type="info" @click="addArticle('草稿')">草稿</el-button></el-form-item></el-form>

5. 添加文章

5.1 重置表单

<el-button type="primary" @click="visibleDrawer = true;resetForm()">添加文章</el-button>const resetForm = () => {if (!articleFormRef.value) returnarticleFormRef.value.resetFields()articleModel.value.content=' '
}

5.2 事件

import { articleListService,articleAddService } from '@/api/article.js'const addArticle = (articleState) => {console.log(articleModel)if(articleModel.value.content==="<p> </p>")articleModel.value.content=''articleFormRef.value.validate(async (valid) => {if (valid) {articleModel.value.state=articleStateconst result = await articleAddService(articleModel.value)const message = result.messageif (result.code == 0) {ElMessage.success(message ? message : '新增成功!')loadArticles()visibleDrawer.value = false} else {ElMessage.error(message ? message : '新增失败,请稍后重试!')}}})
}

四、编辑文章

1. 脚本

export const editArticleService = (articleData)=>{return request.put('/article',articleData)
}

2. 界面

<el-button type="primary" @click="visibleDrawer = true;resetForm();index = 0">添加文章</el-button><!-- 文章列表 -->
<el-table :data="articles" style="width: 100%"><el-table-column label="文章标题" width="400" prop="title"></el-table-column><el-table-column label="分类" prop="categoryName"></el-table-column><el-table-column label="发表时间" prop="createTime"> </el-table-column><el-table-column label="状态" prop="state"></el-table-column><el-table-column label="操作" width="100"><template #default="{ row }"><el-button :icon="Edit" circle plain type="primary" @click="editClick(row)"></el-button><el-button :icon="Delete" circle plain type="danger"></el-button></template></el-table-column><template #empty><el-empty description="没有数据" /></template></el-table>

3. 事件

import { articleListService,articleAddService,editArticleService } from '@/api/article.js'const index=ref(0)
//编辑文章
const editClick = (row) => {resetForm()index.value = 1//title.value = titleArray.value[index.value]visibleDrawer.value = truearticleModel.value.id = row.idarticleModel.value.title = row.titlearticleModel.value.categoryId = row.categoryIdarticleModel.value.coverImg = row.coverImgarticleModel.value.content = row.contentarticleModel.value.state = row.state
}
const editArticle = (articleState) => {if(articleModel.value.state=='已发布'&&articleState==='草稿'){ElMessage.error( '当前文章已发布,不可再变更为草稿状态')return}articleFormRef.value.validate(async (valid) => {if (valid) {articleModel.value.state=articleStateconst result = await editArticleService(articleModel.value)const message = result.messageif (result.code == 0) {ElMessage.success(message ? message : '更新成功!')loadArticles()visibleDrawer.value = false} else {ElMessage.error(message ? message : '更新失败,请稍后重试!')}}})
}

五、删除文章

1. 脚本

export const deleteArticleService = (articleData)=>{return request.delete('/article?id='+articleData)
}

2. 界面

<el-table-column label="操作" width="100"><template #default="{ row }"><el-button :icon="Edit" circle plain type="primary" @click="editClick(row)"></el-button><el-popconfirm title="确认删除吗?" @confirm="deleteClick(row)"><template #reference><el-button :icon="Delete" circle plain type="danger"></el-button></template></el-popconfirm></template>
</el-table-column>

3. 事件

import { articleListService,articleAddService,editArticleService,deleteArticleService } from '@/api/article.js'//删除文章
const deleteClick = async (row) => {const result = await deleteArticleService(row.id)const message = result.messageif (result.code == 0) {ElMessage.success(message ? message : '删除成功!')loadArticles()} else {ElMessage.error(message ? message : '删除失败,请稍后重试!')}
}
