本篇文章給大家詳細分享了Vue Elememt-UI建置管理後台的過程以及相關程式碼實例,一起參考學習下。
安裝
我使用的是vue-cli 初始化項目,指令如下:
npm i -g vue-cli mkdir my-project && cd my-project vue init webpack
修改package.json 檔案:
... "dependencies": { "vue": "^2.5.2", "vue-router": "^3.0.1", "element-ui": "^2.0.7", // element-ui "axios": "^0.17.1" // http 请求库 } ...
之後執行npm install 進行安裝依賴,如果安裝速度有點慢的話,可以試試cnpm ,具體安裝和用法自行查找。
簡單介紹下專案的目錄結構:
├─build // 构建配置 ├─config // 配置文件 ├─src // vue 开发源文件目录 ├────assets // css/js 文件 ├────components // vue 组件 ├────router // 路由 ├────App.vue // 启动组件 ├────main.js // 入口文件 ├─static // 静态文件目录 ├─test // 测试目录
之後在專案根目錄執行 npm run dev ,開啟瀏覽器輸入 http://localhost:8080 就可以查看了。
目標
登入頁面,登錄,退出功能
首頁,呼叫介面渲染清單
路由
路由使用的是vue-router,具體用法可參考官方文件
我們這裡需要兩個路由:
src/router/index.js
import Vue from 'vue' import Router from 'vue-router' import Index from '@/components/Index' import Login from '@/components/Login' Vue.use(Router) const routers = new Router({ routes: [ { path: '/index', name: 'index', component: Index }, { path: '/login', name: 'login', component: Login } ] }) routers.beforeEach((to, from, next) => { if (to.name !== 'login' && !localStorage.getItem('token')) { next({path: 'login'}) } else { next() } }) export default routers
登入頁面
<template> <p class="login"> <el-form name="aa" :inline="true" label-position="right" label-width="80px"> <el-form-item label="用户名"> <el-input v-model="user.name"></el-input> </el-form-item> <el-form-item label="密码"> <el-input type="password" v-model="user.password"></el-input> </el-form-item> <el-form-item label=" "> <el-button type="primary" @click="login()">登录</el-button> </el-form-item> </el-form> </p> </template> <script> import $http from '@/api/' import config from '@/config' export default { data () { return { user: { name: '', password: '' } } }, mounted: function () { var token = localStorage.getItem('token') if (token) { this.$router.push('/index') } }, methods: { login: function () { var data = { grant_type: 'password', client_id: config.oauth_client_id, client_secret: config.oauth_secret, username: this.user.name, password: this.user.password } var _this = this $http.login(data).then(function (res) { if (res.status === 200) { $http.setToken(res.data.access_token) _this.$message({ showClose: false, message: '登录成功', type: 'success' }) _this.$router.push('/index') } else { _this.$message({ showClose: false, message: '登录失败', type: 'error' }) } }) } } } </script> <style> .login{ width: 300px; margin: 100px auto; background-color: #ffffff; padding: 30px 30px 5px; border-radius: 5px; } </style>
首頁
<template> <p class="main"> <el-table stripe v-loading="loading" element-loading-background="#dddddd" :data="tableData" style="width: 100%"> <el-table-column prop="id" label="ID"> </el-table-column> <el-table-column prop="name" label="名称"> </el-table-column> </el-table> <el-pagination background layout="prev, pager, next" :total="total" class="page" @current-change="pageList"> </el-pagination> </p> </template> <script> import $http from '@/api/' export default { data () { return { tableData: [], total: 0, loading: false } }, mounted: function () { this.getList() }, methods: { pageList: function (page) { this.search.page = page this.getList() }, getList: function () { var _this = this _this.loading = true $http.index().then(function (res) { if (res.status === 200) { _this.tableData = res.data.data.lists _this.total = res.data.data.total } _this.loading = false }) } } } </script>
#App
<template> <p id="app"> <el-row v-if="token"> <menus class="left-menu"> <h3 class="logo"><a href="/" rel="external nofollow" >Admin</a></h3> </menus> <el-col :span="21" :gutter="0" :offset="3"> <el-breadcrumb separator-class="el-icon-arrow-right" class="breadcrumb"> <el-breadcrumb-item :to="{ path: '/' }">首页</el-breadcrumb-item> <el-breadcrumb-item class="active">列表</el-breadcrumb-item> </el-breadcrumb> <el-dropdown @command="operate" class="header"> <img src="/static/image/head.jpg" /> <el-dropdown-menu slot="dropdown" :click="true"> <el-dropdown-item command="/user/profile">基本资料</el-dropdown-item> <el-dropdown-item command="/logout">安全退出</el-dropdown-item> </el-dropdown-menu> </el-dropdown> <router-view/> </el-col> <el-col :span="21" :gutter="0" :offset="3" class="footer">Copyright © 2017 Flyerboy All Rights Reserved</el-col> </el-row> <router-view v-if="!token" /> </p> </template> <script> import Menus from '@/components/Menu' export default { name: 'App', data () { return { token: false } }, mounted: function () { this.token = localStorage.getItem('token') ? true : false }, watch: { '$route.path': function ($newVal, $oldVal) { this.token = localStorage.getItem('token') ? true : false } }, methods: { operate: function (command) { if (command === '/logout') { localStorage.removeItem('token') this.$router.push('login') } else { this.$router.push(command) } } }, components: { Menus } } </script> <style> body{ margin: 0; padding: 0; background-color: #eeeeee; } .header{ position: absolute; top: 5px; right: 20px; } .header img{ width: 38px; height: 38px; border-radius: 20px; border: 1px solid #aaaaaa; } #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } .main{ padding: 20px; min-height: 600px; margin-bottom: 20px; } .main table{ background: #ffffff; } .left-menu{ background-color: #33374B; } .logo{ padding: 20px 0 15px 20px; font-size: 24px; border-bottom: 2px solid #3a8ee6; } .logo a{ color: #ffffff; text-decoration: none; } .left-menu .el-menu{ border-right: 0; } .breadcrumb{ line-height: 40px; padding: 5px 20px; background: #ffffff; } .breadcrumb span{ color: #069; font-weight: normal; } .breadcrumb .active{ color: #aaaaaa; } .page{ margin: 20px 0 0; margin-left: -10px; } .page .el-pager li.number{ background-color: #ffffff; } .el-submenu .el-menu-item{ padding-left: 60px !important; } .footer{ position: fixed; bottom: 0; right: 0; font-size: 12px; color: #888888; padding: 15px 20px; text-align: center; background-color: #ffffff; margin-top: 40px; } </style>
#呼叫API
import axios from 'axios' axios.defaults.baseURL = 'http://localhost:8000/' axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded' axios.defaults.headers.common['Authorization'] = 'Bearer ' + localStorage.getItem('token') export default { setToken: function (token) { localStorage.setItem('token', token) axios.defaults.headers.common['Authorization'] = 'Bearer ' + token }, login: function (param) { return axios.post('oauth/token', param) }, index: function (params) { return axios.get('api/user/list', { params: params }) } }
#config
export default { oauth_client_id: 2, oauth_secret: '' }
main.js
import Vue from 'vue' import App from './App' import router from './router' import ElementUI from 'element-ui' import 'element-ui/lib/theme-chalk/index.css' Vue.use(ElementUI) Vue.config.productionTip = false new Vue({ el: '#app', router, components: { App }, template: '<App/>' })api 接口
