【java爬虫】使用vue+element-plus编写一个简单的管理页面-编程知识

前言

前面我们已经将某宝联盟的数据获取下来了，并且编写了一个接口将数据返回，现在我们需要使用vue+element-plus编写一个简单的管理页面进行数据展示，由于第一次使用vue编写前端项目，所以只是编写了一个非常简单的页面。

项目结构

先来简单介绍一下项目结构，本次项目非常简单，我只是使用了vue3+element-plus，只是一个demo样例，后续可以添加其他的新功能。

整体布局就是传统的管理系统的布局，一共由三个部分组成，分别是头部，侧边栏和主页面

头部可以填写一些信息，包括用户的登录登出操作，侧边栏就是一些按钮，用来切换主页面，主页面就是展示我们的具体信息。

本次的案例我们只有两个页面，一个是首页，一个就是详细的数据页面，在vue项目中分别对应了两个组件，其中首页我只是简单用文字描述了一下。

下面来看一下详细的项目结构

首先是main.js，这是vue项目的主函数，在这里将我们需要用到的三方库都引进来

import { createApp } from 'vue'
import ElementPlus from 'element-plus';
import 'element-plus/dist/index.css';
import App from './App.vue'const app = createApp(App);app.use(ElementPlus);
app.mount('#app');

接着是App.vue，这个页面就是我们的主页面，我们将大体的程序框架都写在这个文件中

<template><div><el-container><el-header style="background-color:beige;">欢迎使用管理系统</el-header><el-container><el-aside width="200px" style="background-color:cornsilk;"><el-menu@select="selectfunc"default-active="1"class="el-menu-vertical-demo"><el-menu-item index="1"><el-icon><icon-menu /></el-icon><span>首页</span></el-menu-item><el-menu-item index="2"><el-icon><icon-menu /></el-icon><span>数据详情</span></el-menu-item></el-menu></el-aside><el-main style="background-color: blanchedalmond;"><div v-show="display1"><MainView></MainView></div><div v-show="display2"><InfoDetail></InfoDetail></div></el-main></el-container></el-container></div>
</template><script>
import InfoDetail from './components/InfoDetail.vue';
import MainView from './components/MainView.vue';export default {name: 'App',data() {return {display1:true, display2:false};},components: {InfoDetail, MainView},methods: {selectfunc : function(index) {if(index == 1) {console.log("点击了首页");this.display1 = true;this.display2 = false;} else if (index == 2) {console.log("点击了数据详情");this.display1 = false;this.display2 = true;}}},
}
</script><style>
#app {font-family: Avenir, Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;text-align: center;color: #2c3e50;
}
</style>

最后就是我们引入的两个组件，一个是首页，这个组件我们只是用一个简单的占位符进行表示，后续还可以更新其他的内容

<template><el-text>这是主页</el-text>
</template><script>
export default {name: 'MainView',
}
</script>

最后就是我们的详细的数据页面，我们使用element-plus的表格进行表示

<template><el-table :data="tableData" stripe style="width: 100%"><el-table-column prop="imgUrl" label="图片"><template v-slot:default="scope"><el-image :src="scope.row.imgUrl"/></template></el-table-column><el-table-column prop="title" label="标题"><template v-slot:default="scope"><el-text truncated>{{ scope.row.title }}</el-text></template></el-table-column><el-table-column prop="commission" label="佣金"></el-table-column><el-table-column prop="commissionRate" label="佣金率"></el-table-column><el-table-column prop="prePrice" label="券前价格"></el-table-column><el-table-column prop="postPrice" label="券后价格"></el-table-column><el-table-column prop="preferentialPrice" label="优惠价格"></el-table-column><el-table-column prop="preferentialRate" label="优惠率"><template v-slot:default="scope"><el-text>{{ Math.round(scope.row.preferentialRate*100) }}%</el-text></template></el-table-column><el-table-column prop="recommend" label="淘口令"><template v-slot:default="scope"><el-text truncated>{{ scope.row.recommend }}</el-text></template></el-table-column><el-table-column prop="serializeTime" label="创建时间"></el-table-column></el-table>
</template><script>

在使用element-plus的表格的时候可能会报错，我们需要在vue.config.js中添加一个段内容
