一、创建项目
1.创建项目
2.安装各种依赖
npm install
@highlightjs/vue-plugin
@moefe/vue-aplayer
aplayer
axios
docx-preview
dplayer
element-plus
highlight.js
js-md5
sass
sass-loader
spark-md5
vue-clipboard3
vue-cookies
vue-pdf-embed
vue-router
vue3-pdfjs
xlsx
--save
3.修改端口号
vite.config.js
server: {
port: 1024,
hmr: true,
proxy: {
'/api': {
target: 'http://localhost:7090',
changeOrigin: true,
pathRewrite: {
'^api': '/api',
},
},
},
},4.引入各项安装
main.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
//引入element plus
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
//图标图标在附件中
import '@/assets/icon/iconfont.css'
import '@/assets/base.scss'
// 引入cookies
import { VueCookies } from 'vue-cookies'
const app = createApp(App)
app.use(router)
app.use(ElementPlus)
app.mount('#app')
index.html

margin-right: 20px; color: #05a1f5; } } } } } .body-content { flex: 1; width: 0; padding-left: 20px; } } </style>（2）添加路由
./src/router/index.js{ path: '/', name: 'Framework', component: ()=> import('@/views/Framework.vue'), children: [{ path: '/', redirect: "/main/all" }, { path: '/main/:category', name: '首页', meta: { needLogin: true, menuCode: "main" }, component: () => import ("@/views/main/Main.vue") }, { path: '/myshare', name: '我的分享', meta: { needLogin: true, menuCode: "share" }, component: () => import ("@/views/share/Share.vue") }, { path: '/recycle', name: '回收站', meta: { needLogin: true, menuCode: "recycle" }, component: () => import ("@/views/recycle/Recycle.vue") }, { path: '/settings/sysSetting', name: '系统设置', meta: { needLogin: true, menuCode: "settings" }, component: () => import ("@/views/admin/SysSettings.vue") }, { path: '/settings/userList', name: '用户管理', meta: { needLogin: true, menuCode: "settings" }, component: () => import ("@/views/admin/UserList.vue") }, { path: '/settings/fileList', name: '用户文件', meta: { needLogin: true, menuCode: "settings" }, component: () => import ("@/views/admin/FileList.vue") }, ] },（3）添加如下组件
（4）main.js引入使用
import Avatar from '@/components/Avatar.vue'
（5）./src/components/Avatar.vue<template> <!-- 头像组件 --> <span class="avatar"> <img :src="avatar && avatar != '' ? avatar : `${proxy.globalInfo.avatarUrl}${userId}?${timestamp}` " v-if="userId" /> </span> </template> <script setup> import { getCurrentInstance } from "vue"; // 获取当前组件实例 const { proxy } = getCurrentInstance(); const props = defineProps({ userId: { type: String, }, avatar: { type: String, }, timestamp: { type: Number, default: 0, }, width: { type: Number, default: 40, }, }); </script> <style lang="scss" scoped> .avatar { display: flex; width: 40px; height: 40px; border-radius: 50%; overflow: hidden; img { width: 100%; object-fit: cover; } } </style>
四、上传头像
（1）封装UpdateAvatar.vue组件
./src/views/UpdateAvatar.vue<template> <div> <!-- 修改头像弹出框 --> <Dialog :show="dialogConfig.show" :title="dialogConfig.title" :buttons="dialogConfig.buttons" width="500px" :showCancel="true" @close="dialogConfig.show = false" > <el-form :model="formData" ref="formDataRef" label-width="80px" @submit.prevent > <!--显示昵称--> <el-form-item label="昵称"> {{ formData.nickName }} </el-form-item> <!--显示头像--> <el-form-item label="头像"> <AvatarUpload v-model="formData.avatar"></AvatarUpload> </el-form-item> </el-form> </Dialog> </div> </template> <script setup> // 引入头像上传组件 import AvatarUpload from "@/components/AvatarUpload.vue"; import { ref, reactive, getCurrentInstance } from "vue"; import { useRouter, useRoute } from "vue-router"; const { proxy } = getCurrentInstance(); const router = useRouter(); const route = useRoute(); const api = { updateUserAvatar: "updateUserAvatar", }; const formData = ref({}); const formDataRef = ref(); const show = (data) => { formData.value = Object.assign({}, data); formData.value.avatar = { userId: data.userId, qqAvatar: data.avatar }; dialogConfig.value.show = true; }; // 子组件暴露自己的属性 // 父组件需要调用子组件的方法父组件需要调用子组件的方法， // 或者访问子组件的变量 defineExpose({ show }); // 定义弹出框的属性 const dialogConfig = ref({ show: false, title: "修改头像", buttons: [ { type: "primary", text: "确定", click: (e) => { submitForm(); }, }, ], }); // 1、在子组件中调用defineEmits并定义要发射给父组件的方法 // 2、使用defineEmits会返回一个方法，使用一个变量emit(变量名随意)去接收 // 3、在子组件要触发的方法中，调用emit并传入发射给 父组件的方法（updateAvatar） const emit = defineEmits(["updateAvatar"]); // 点击确定 提交的回调 const submitForm = async () => { // 如果上传的不是文件，将关闭弹出框 if (!(formData.value.avatar instanceof File)) { dialogConfig.value.show = false; } let result = await proxy.Request({ url: api.updateUserAvatar, params: { avatar: formData.value.avatar, }, }); if (!result) { return; } dialogConfig.value.show = false; const cookeUserInfo = proxy.VueCookies.get("userInfo"); delete cookeUserInfo.avatar; proxy.VueCookies.set("userInfo", cookeUserInfo, 0); // 在子组件要触发的方法中，调用emit并传入发射给 父组件的方法（updateAvatar） emit("updateAvatar"); }; </script> <style lang="scss"> </style>（2）封装全局组件AvatarUpload（上传图片）
./src/commponents/AvatarUpload.vue<template> <!-- 头像上传 --> <div class="avatar-upload"> <div class="avatar-show"> <template v-if="localFile"> <img :src="localFile" /> </template> <template v-else> <img :src="`${modelValue.qqAvatar}`" v-if="modelValue && modelValue.qqAvatar" /> <img :src="`/api/getAvatar/${modelValue.userId}`" v-else /> </template> </div> <div class="select-btn"> <el-upload name="file" :show-file-list="false" accept=".png,.PNG,.jpg,.JPG,.jpeg,.JPEG,.gif,.GIF,.bmp,.BMP" :multiple="false" :http-request="uploadImage" > <el-button type="primary">选择</el-button> </el-upload> </div> </div> </template> <script setup> import { ref, reactive, getCurrentInstance } from "vue"; import { useRouter, useRoute } from "vue-router"; const { proxy } = getCurrentInstance(); const router = useRouter(); const route = useRoute(); const timestamp = ref(""); // defineProps是一个函数 定义后props可直接在模板中使用，或者在setup其他地方使用 const props = defineProps({ modelValue: { type: Object, default: null, }, }); // 本地图片 const localFile = ref(null); // 子组件向父组件传值 const emit = defineEmits(); // 上传图片 const uploadImage = async (file) => { file = file.file; let img = new FileReader(); img.readAsDataURL(file); img.onload = ({ target }) => { localFile.value = target.result; }; emit("update:modelValue", file); }; </script> <style lang="scss"> .avatar-upload { display: flex; justify-content: center; align-items: end; .avatar-show { background: rgb(245, 245, 245); width: 150px; height: 150px; display: flex; align-items: center; justify-content: center; overflow: hidden; position: relative; .iconfont { font-size: 50px; color: #ddd; } img { width: 100%; height: 100%; } .op { position: absolute; color: #0e8aef; top: 80px; } } .select-btn { margin-left: 10px; vertical-align: bottom; } } </style>（3）Framework.vue中引入使用
<!-- 修改头像组件 --> <UpdateAvatar ref="updateAvatarRef" @updateAvatar="reloadAvatar"></UpdateAvatar> import UpdateAvatar from "./UpdateAvatar.vue";（4）添加点击事件
<el-dropdown-item @click="updateAvatar">修改头像</el-dropdown-item> ...... // 修改头像 const updateAvatarRef = ref(); // 利用defineExpose，父组件调用子组件的函数， // 将用户信息利用show传递给子组件的show函数，使得子组件更新信息 const updateAvatar = () => { updateAvatarRef.value.show(userInfo.value); }; // 重新加载最新头像，利用子组件的 emit("updateAvatar"); 传递回来的信息， const reloadAvatar = () => { userInfo.value = proxy.VueCookies.get("userInfo"); timestamp.value = new Date().getTime(); };
五、修改密码
（1）封装UpdatePassword.vue组件
./src/views/UpdatePassword.vue
<template> <div> <!-- 修改头像弹出框 --> <Dialog :show="dialogConfig.show" :title="dialogConfig.title" :buttons="dialogConfig.buttons" width="500px" :showCancel="true" @close="dialogConfig.show = false" > <el-form :model="formData" :rules="rules" ref="formDataRef" label-width="80px" @submit.prevent > <!--输入新密码--> <el-form-item label="新密码" prop="password"> <el-input type="password" size="large" placeholder="请输入密码" v-model.trim="formData.password" show-password > <template #prefix> <span class="iconfont icon-password"></span> </template> </el-input> </el-form-item> <!-- 再次输入密码 --> <!--输入新密码--> <el-form-item label="确认密码" prop="rePassword"> <el-input type="password" size="large" placeholder="请再次输入密码" v-model.trim="formData.rePassword" show-password > <template #prefix> <span class="iconfont icon-password"></span> </template> </el-input> </el-form-item> </el-form> </Dialog> </div> </template> <script setup> import AvatarUpload from "@/components/AvatarUpload.vue"; import { ref, reactive, getCurrentInstance, nextTick } from "vue"; const { proxy } = getCurrentInstance(); const api = { updatePassword: "updatePassword", }; const formData = ref({}); const formDataRef = ref(); // 校验再次输入的密码 const checkRePassword = (rule, value, callback) => { if (value !== formData.value.rePassword) { callback(new Error(rule.message)); } else { callback(); } }; const rules = { password: [ { required: true, message: "请输入密码" }, { validator: proxy.Verify.password, message: "密码只能是数字，字母，特殊字符 8-18 位", }, ], rePassword: [ { required: true, message: "请再次输入密码" }, { validator: checkRePassword, message: "两次输入的密码不一致", }, ], }; const show = () => { dialogConfig.value.show = true; nextTick(() => { formDataRef.value.resetFields(); formData.value = {}; }); }; // 子组件暴露自己的属性 // 父组件需要调用子组件的方法父组件需要调用子组件的方法， // 或者访问子组件的变量 defineExpose({ show }); const dialogConfig = ref({ show: false, title: "修改密码", buttons: [ { type: "primary", text: "确定", click: (e) => { submitForm(); }, }, ], }); const submitForm = async () => { formDataRef.value.validate(async (valid) => { if (!valid) { return; } let result = await proxy.Request({ url: api.updatePassword, params: { password: formData.value.password, }, }); if (!result) { return; } dialogConfig.value.show = false; proxy.Message.success("密码修改成功"); }); }; </script> <style lang="scss"> </style>（2）在Framework.vue引入，使用组件
<!-- 修改密码组件 --> <UpdatePassword ref="updatePasswordRef"></UpdatePassword>import UpdatePassword from "./UpdatePassword.vue";（3）添加点击事件，点击事件回调
<el-dropdown-item @click="updatePassword">修改密码</el-dropdown-item>// 修改密码 const updatePasswordRef = ref(); const updatePassword = () => { updatePasswordRef.value.show(); };
六、退出登录
（1）封装全局组件
./src/utils/Confirm.jsimport { ElMessageBox } from 'element-plus' const confirm = (message, okfun) => { ElMessageBox.confirm(message, '提示', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'info', }).then(() => { okfun() }).catch(() => {}) } export default confirm;（2）main.js引入和配置
import Confirm from './utils/Confirm'; app.config.globalProperties.Confirm=Confirm（3）添加api接口
const api = { // getUseSpace: "/getUseSpace", logout: "/logout", };（4）添加点击事件
<el-dropdown-item @click="logout">退出</el-dropdown-item> // 退出登录 const logout = () => { proxy.Confirm(`你确定要删除退出吗`, async () => { let result = await proxy.Request({ url: api.logout, }); if (!result) { return; } proxy.VueCookies.remove("userInfo"); router.push("/login"); }); };
