1. 首先請求服務器,獲取當前用戶的權限數據,比如請求 this.$http.get("rights/list");

　　2. 獲取到權限數據之后,在列表中使用v-if v-if-else的組合來展示不同的內容

<template>

 <div>

   <!-- 面包屑導航區 -->

   <el-breadcrumb separator-class="el-icon-arrow-right">

     <el-breadcrumb-item :to="{ path: '/home' }">首頁</el-breadcrumb-item>

     <el-breadcrumb-item>權限管理</el-breadcrumb-item>

     <el-breadcrumb-item>權限列表</el-breadcrumb-item>

   </el-breadcrumb>

   <!-- 卡片視圖 -->

   <el-card>

     <el-table :data="rightsList" border stripe>

       <el-table-column type="index" label="#"></el-table-column>

       <el-table-column label="權限名稱" prop="authName"></el-table-column>

       <el-table-column label="路徑" prop="path"></el-table-column>

       <el-table-column label="權限等級" prop="level">

         <template slot-scope="scope">

           <el-tag v-if="scope.row.level === '0'">一級</el-tag>

           <el-tag type="success" v-else-if="scope.row.level === '1'">二級</el-tag>

           <el-tag type="danger" v-else>三級</el-tag>

         </template>

       </el-table-column>

     </el-table>

   </el-card>

 </div>

</template>

<script>

export default {

 data() {

   return {

     // 權限列表

     rightsList: []

   };

 },

 created() {

   this.getRightsList();

 },

 methods: {

   async getRightsList() {

     //獲取權限列表數據

     const { data: res } = await this.$http.get("rights/list");

     if (res.meta.status !== 200) {

       return this.$message.error("獲取權限列表失敗！");

     }

     this.rightsList = res.data;

   }

 }

};
