1 新建 List.vue 组件

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

                </el-row>
                
                <el-table :data="goodslist" border stripe>

                </el-table>
                
                <el-pagination

    <script>
        export default {
            name: "List",
            data() {
                return {
                    /* 查询参数对象 */
                    queryInfo: {
                        query: '',
                        pagenum: 1,
                        pagesize: 10

                    // 商品列表
                    goodslist: [],

                    total: 0
                }
            },
            created() {
                this.getGoodsList()
            },
            methods: {
                // 根据分页获取对应的商品列表
                async getGoodsList() {
                    const {data: res} = await this.$http.get('goods', {params: this.queryInfo})
                    if (res.meta.status !== 200) {
                        return this.$message.error('获取商品列表失败')
                    }
    
                    this.$message.success('获取商品列表成功')
                    console.log(res.data)

            }
        }
    </script>
    
    <style scoped>
    
    </style>

2 修改路由 index.js

import Vue from 'vue'
    import VueRouter from 'vue-router'
    // 导入登录组件
    import Login from "../components/Login";
    // 导入Home 组件
    import Home from "../components/Home";
    // 导入Welcome 组件
    import Welcome from "../components/Welcome";
    // 导入 Users 组件
    import Users from "../components/user/Users";
    // 导入权限列表 组件
    import Rights from "../components/power/Rights";
    // 导入角色列表 组件
    import Roles from "../components/power/Roles";
    // 导入商品分类 组件
    import Cate from "../components/goods/Cate";
    // 导入商品分类参数 组件
    import Params from "../components/goods/Params";
    // 导入商品列表组件
    import GoodsList from "../components/goods/List";
    import {renderThumbStyle} from "element-ui/packages/scrollbar/src/util";
    
    
    Vue.use(VueRouter)
    
    const routes = [
        // 路由重定向,当访问/,就会重定向到/login
        {
            path: '/',
            redirect: '/login'
        },
        // 定义登录路由规则
        {
            path: '/login',
            component: Login
        },
        // 定义Home的路由规则
        {
            path: '/home',
            component: Home,
            redirect: '/welcome',
            children: [
                {
                    path: '/welcome',
                    component: Welcome
                },
                /* 用户管理 */
                {
                    path: '/users',
                    component: Users
                },
                /* 权限管理 */
                {
                    path: '/rights',
                    component: Rights
                },
                /* 角色管理 */
                {
                    path: '/roles',
                    component: Roles
                },
                /* 商品分类 */
                {
                    path: '/categories',
                    component: Cate
                },
                /* 商品分类参数 */
                {
                    path: '/params',
                    component: Params
                },
                /* 商品列表 */
                {
                    path: '/goods',
                    component: GoodsList
                },
    
            ]
        }
    ]
    
    const router = new VueRouter({
        routes
    })
    // 挂载路由导航守卫
    // to 将要访问的路径
    // from 代表从哪个路径跳转而来
    // next 是个函数，表示放行 next() 放行  next('/login') 强制跳转
    router.beforeEach((to, from, next) => {
        // 如果用户访问的登录页，直接放行
        if (to.path === '/login') return next();
        // 从 sessionStorage 中获取到保存的 token 值
        const tokenstr = window.sessionStorage.getItem('token')
        // 没有 token，强制跳转到登录页
        if (!tokenstr) return next('/login')
        next()
    })
    
    export default router

3 给 main.js 增加时间过滤器

import Vue from 'vue'
    import App from './App.vue'
    import router from './router'
    import './plugins/element.js'
    // 导入阿里的字体图标
    import './assets/fonts/iconfont.css'
    // 导入全局样式表,使得全局样式生效
    import './assets/css/global.css'
    // 全局导入axios
    import axios from 'axios'
    // 导入TreeTable 插件
    import TreeTable from 'vue-table-with-tree-grid'
    // 设置axios请求的根路径
    axios.defaults.baseURL = 'http://127.0.0.1:8888/api/private/v1/'
    // axios请求拦截
    axios.interceptors.request.use(config => {
        // 为请求头对象，添加 Token 验证的 Authorization 字段
        config.headers.Authorization = window.sessionStorage.getItem('token')
        return config
    })
    Vue.prototype.$http = axios
    
    
    Vue.config.productionTip = false
    // 注册 TreeTable 组件
    Vue.component('tree-table', TreeTable)
    // 添加时间过滤器
    Vue.filter('dateFormat', function (originVal) {
        const dt = new Date(originVal)
    
        const y = dt.getFullYear()
        const m = (dt.getMonth() + 1 + '').padStart(2, '0')
        const d = (dt.getDate() + '').padStart(2, '0')
        const hh = (dt.getHours() + '').padStart(2, '0')
        const mm = (dt.getMinutes() + '').padStart(2, '0')
        const ss = (dt.getSeconds() + '').padStart(2, '0')
    
        return `${y}-${m}-${d} ${hh}:${mm}:${ss}`
    
    })
    
    new Vue({
        router,
        render: h => h(App)
    }).$mount('#app')
