1 新建 List.vue 组件

<template>
    <div>
        <!-- 面包屑导航区 -->
        <el-breadcrumb separator-class="el-icon-arrow-right">
            <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>

            <el-breadcrumb-item>商品列表</el-breadcrumb-item>
        </el-breadcrumb>
        <!-- 卡片视图-->
        <el-card>
            <el-row :gutter="20">
                <el-col :span="8">
                    <el-input placeholder="请输入内容" v-model="queryInfo.query" clearable @clear="getGoodsList">
                        <el-button slot="append" icon="el-icon-search" @click="getGoodsList"></el-button>

                </el-col>
            </el-row>
            <!-- table 表格区域-->

                        {{scope.row.add_time | dateFormat}}
                    </template>
                </el-table-column>
                <el-table-column label="操作" width="230px">
                    <template slot-scope="scope">
                        <el-button type="primary" icon="el-icon-edit" size="mini">编辑</el-button>
                        <el-button type="danger" icon="el-icon-delete" size="mini">删除</el-button>
                    </template>
                </el-table-column>

            </el-table>
            <!-- 分页区-->
            <el-pagination
                    @size-change="handleSizeChange"
                    @current-change="handleCurrentChange"
                    :current-page="queryInfo.pagenum"
                    :page-sizes="[5, 10, 15, 20]"
                    :page-size="queryInfo.pagesize"
                    layout="total, sizes, prev, pager, next, jumper"
                    :total="total" background>
            </el-pagination>
        </el-card>
    </div>
</template>

<script>
    export default {
        name: "List",
        data() {
            return {
                /* 查询参数对象 */
                queryInfo: {
                    query: '',
                    pagenum: 1,
                    pagesize: 10
                },
                // 商品列表
                goodslist: [],
                // 总数据条数
                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)
                this.goodslist = res.data.goods
                this.total = res.data.total
            },
            handleSizeChange(newSize){
                this.queryInfo.pagesize = newSize
                this.getGoodsList()
            },
            handleCurrentChange(newPage){
                this.queryInfo.pagenum = newPage
                this.getGoodsList()
            }
        }
    }
</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')
