从0开始搭建vue + flask 旅游景点数据分析系统（二）：搭建基础框架

这一期目标是把系统的布局给搭建起来，采用一个非常简单的后端管理风格，可以参考官方的页面
https://element.eleme.cn/#/zh-CN/component/container

下面我们开始搭建，首先，安装一下vue-router，element-ui

npm install vue-router@3
npm install element-ui

然后在src目录下创建layouts文件夹和router文件夹 ，

在layouts文件夹下建立Layout.vue文件

<template><el-container class="container"><el-aside width="200px" style="background-color: rgb(229,227,238)"><el-menu :default-active="activeIndex" active-text-color="#BAA7FFFF"	class="el-menu-vertical"><el-menu-item index="/dashboard" @click="navigateTo('/dashboard')">Dashboard</el-menu-item><el-menu-item index="/users" @click="navigateTo('/users')">Users</el-menu-item><!-- 其他菜单项 --></el-menu></el-aside><el-container><el-header class="header"><div class="logo">My Admin</div></el-header><el-main class="main"><router-view></router-view></el-main></el-container></el-container>
</template><script>
export default {data() {return {activeIndex: '/dashboard'};},methods: {navigateTo(path) {console.log(this.activeIndex);if (this.$route.path !== path) {this.activeIndex = path;this.$router.push(path);}}}
};
</script><style scoped>
.container{height: 100vh;border: 1px solid #eee;
}.header {background-color: #ffffff;text-align: center;line-height: 60px;border-bottom: 1px solid #ebeef5;
}.logo {font-size: 20px;font-weight: bold;
}.main {padding: 20px;
}
</style>

在router下建立index.js文件，

import Vue from 'vue';
import Router from 'vue-router';
import Layout from '@/layouts/Layout';// 引入页面组件
import Dashboard from '@/views/Dashboard';
import Users from '@/views/Users';Vue.use(Router);const routes = [{path: '/',component: Layout,redirect: '/dashboard',children: [{path: 'dashboard',component: Dashboard,name: 'Dashboard'},{path: 'users',component: Users,name: 'Users'}// 其他子路由]},// 其他路由
];const router = new Router({mode: 'history',routes
});export default router;

因为想访问 / 直接转到 /dashboard ,所以有这行设置：

 redirect: '/dashboard',

还需要新建views文件夹，新增两个vue文件Dashboard.vue和Users.vue

<!-- Dashboard.vue -->
<template><div className="dashboard"><h1>Dashboard</h1><!-- Dashboard 内容 --></div>
</template><script>
export default {name: 'Dashboard'
};
</script><style scoped>
.dashboard {/* 样式 */
}
</style><!-- Users.vue -->
<template><div class="users"><h1>Users</h1><!-- Users 内容 --></div>
</template><script>
export default {name: 'Users'
};
</script><style scoped>
.users {/* 样式 */
}
</style>

修改main.js ，引入上面我们新增的内容：

import Vue from 'vue'
import App from './App.vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import router from './router'Vue.use(ElementUI)Vue.config.productionTip = falsenew Vue({router,render: h => h(App),
}).$mount('#app')

运行程序:

npm run serve

效果：
