2.项目结构、设计说明

项目以vue项目创建，前端某些元素使用element，项目启动执行的命令为：

npm install
npm run dev（当然命令可以修改为npm run serve，没啥区别）

注意：npm install 成功了再执行 npm run dev 启动项目
结构如下截图，项目已经集成和实现了需要请求后端接口的一切功能，所以无须花费精力去考虑前端如何去对接后端和接口，可以把一切精力放在实现前端界面设计上来。

这样不懂后端的伙伴也省心省力，接口请求只需按照模板去copy就好，无非就是get/post/delete/put等请求方式和参数传递的差别，当然不明白的可以细问作者。

项目结构还是分为：顶部+具体功能显示容器+底部，页面存放于src/page目录下，看目录命名就能明白其含义，具体功能页面在views目录下。

路由在router目录中。

路由权限也是很重要的一个功能，为permission.js，所有页面跳转都会经过其拦截，有人问，路由权限有什么用，好说，比如订单页面或个人中心页面吧，肯定是需要登录才能访问的，首页却是无需登录即可访问的，那么就可以在permission.js里面获取登录token，有token即表示已经登录，可以访问订单或个人中心页面，否则跳转登录页等。

项目结构图：

3.路由配置实现

import Vue from 'vue'
import Router from 'vue-router'
import Layout from '@/page/index/index'Vue.use(Router)export default new Router({routes: [{path: '/index',component: Layout,children: [{path: '',name: '主页',component: () =>import( /* webpackChunkName: "views" */ '@/views/home/index')}]},{path: '/',name: '主页',redirect: '/index'},{path: '/type',component: Layout,children: [{path: '',name: '分类',component: () =>import( /* webpackChunkName: "views" */ '@/views/type/index')}]},{path: '/cart',component: Layout,children: [{path: '',name: '购物车',component: () =>import( /* webpackChunkName: "views" */ '@/views/cart/index')}]},{path: '/user',component: Layout,children: [{path: '',name: '我的',component: () =>import( /* webpackChunkName: "views" */ '@/views/user/index')}]},{path: '/address',name: '收货地址',component: () =>import( /* webpackChunkName: "page" */ '@/views/address/index'),},{path: '/login',name: '登录/注册',component: () =>import( /* webpackChunkName: "page" */ '@/views/login/index'),},{path: '/search',name: '搜索',component: () =>import( /* webpackChunkName: "page" */ '@/views/search/index'),},{path: '/setting',name: '设置',component: () =>import( /* webpackChunkName: "page" */ '@/views/user/setting'),},{path: '/productDetail',name: '商品详情',component: () =>import( /* webpackChunkName: "page" */ '@/views/product/detail'),}]
})

4.首页实现源码

5.登录注册实现，模拟登录注册流程，用户数据存储到本地浏览器缓存

实现逻辑源码：

<script>import {getStore,setStore} from "@/utils/store.js";import { setToken } from '@/utils/auth';export default {data() {return {modalType: 'login',defaultAvatar: require('../../../public/img/avatar.jpg'),//注册默认头像loginForm: {username:'',//用户名password: "",//密码},registerForm: {username:'',//用户名password: "",//密码confirmPassword: "",//确认密码},userInfo:{},userList:[],//全部用户列表showTip: false,//验证提示tip: ''//提示语};},mounted() {},methods: {goBack(){//返回this.$router.go(-1)},clearTip(){this.showTip = false;this.tip = '';},resetForm(){//重置this.loginForm = {username:'',password: ""};this.registerForm = {username:'',password: "",confirmPassword: ""};this.showTip = false;this.tip = '';},changeModalType(type){//切换登录、注册this.modalType = type;this.resetForm();},handleLogin() {//登录let that = this;that.tip = '';that.showTip = false;that.userInfo = {};if(that.loginForm.username.trim() === ''){that.tip = '账号名不能为空';that.showTip = true;return;}if(that.loginForm.password.trim() === ''){that.tip = '密码不能为空';that.showTip = true;return;}const loading = that.$loading({lock: true,text: '登录中,请稍后。。。',spinner: "el-icon-loading"});//获取所有用户let userList = getStore({name:'userList'});if(userList){that.userList = userList;let hadUser = false;//循环拼单是否存在用户that.userList.forEach((item,index)=>{if(item.username === that.loginForm.username && item.password === that.loginForm.password){hadUser = true;that.userInfo = item;//模拟登录用户 存到缓存that.$store.commit('SET_USER_INFO', that.userInfo);//设置登录tokensetToken(that.userInfo.id);that.$notify({title: '提示',message: '登录成功',type: 'success'//duration: 0//为0则不会自动关闭});loading.close();that.$router.push({'path':'/user'});}else if(index === (that.userList.length - 1) && !hadUser){that.$message.warning('账号或密码错误');loading.close();}});}else{that.$message.warning('账号或密码错误');loading.close();}},handleRegister() {//注册let that = this;that.tip = '';that.showTip = false;if(that.registerForm.username.trim() === ''){that.tip = '账号名不能为空';that.showTip = true;return;}if(that.registerForm.password.trim() === ''){that.tip = '密码不能为空';that.showTip = true;return;}if(that.registerForm.confirmPassword.trim() === ''){that.tip = '确认密码不能为空';that.showTip = true;return;}if(that.registerForm.password.trim() !== that.registerForm.confirmPassword.trim()){that.tip = '两次输入密码不一致';that.showTip = true;return;}const loading = that.$loading({lock: true,text: '注册中,请稍后。。。',spinner: "el-icon-loading"});//获取所有用户that.userList = getStore({name:'userList'});if(!that.userList){that.userList = [];}let pass = true;if(that.userList.length === 0){that.checkUseRegister();loading.close();}else{that.userList.forEach((item,index)=>{if(pass){if(item.username === that.registerForm.username){that.$message.warning('用户名已存在，请修改');loading.close();pass = false;}}if(pass && index === (this.userList.length-1)){that.checkUseRegister();loading.close();}});}},checkUseRegister(){//注册//模拟注册用户 存到缓存let id = this.userList?(this.userList.length + 1):1;//递增idlet userInfo = {id: id,username: this.registerForm.username,phone: this.registerForm.phone,password: this.registerForm.password,avatar: this.defaultAvatar};this.userList.push(userInfo);//用户列表 - 存储到缓存setStore({name:'userList',content: this.userList});this.$notify({title: '提示',message: '注册成功，请登录',type: 'success',duration: 2000//为0则不会自动关闭});this.modalType = 'login';}}};
