})export default router11、登录页静态布局
目标基于笔记快速实现登录页静态布局
准备工作 (1) 新建 styles/common.less 重置默认样式 (2) main.js 导入 common.less (3) 图片素材拷贝到 assets 目录【备用】登录页静态布局编写 (1) 头部组件说明 (NavBar) (2) 通用样式覆盖 (3) 其他静态结构编写
(1) 准备工作

}
/style添加通用样式
styles/common.less 设置导航条返回箭头颜色
// 设置导航条 返回箭头 颜色
.van-nav-bar {.van-icon-arrow-left {color: #333;}
}12、request模块 - axios 封装
目标将 axios 请求方法封装到 request 模块
使用 axios 来请求后端接口, 一般都会对 axios 进行 一些配置 (比如: 配置基础地址请求响应拦截器等)
所以项目开发中, 都会对 axios 进行基本的二次封装, 单独封装到一个 request 模块中, 便于维护使用 接口文档地址 https://apifox.com/apidoc/shared-12ab6b18-adc2-444c-ad11-0e60f5693f66/doc-2221080 基地址 http://cba.itlike.com/public/index.php?s/api/
安装 axios
npm i axios新建 utils/request.js 封装 axios 模块 利用 axios.create 创建一个自定义的 axios 来使用 http://www.axios-js.com/zh-cn/docs/#axios-create-config
/* 封装axios用于发送请求 */
import axios from axios// 创建一个新的axios实例
const request axios.create({baseURL: http://cba.itlike.com/public/index.php?s/api/,timeout: 5000
})// 添加请求拦截器
request.interceptors.request.use(function (config) {// 在发送请求之前做些什么return config
}, function (error) {// 对请求错误做些什么return Promise.reject(error)
})// 添加响应拦截器
request.interceptors.response.use(function (response) {// 对响应数据做点什么return response.data
}, function (error) {// 对响应错误做点什么return Promise.reject(error)
})export default request获取图形验证码请求测试
import request from /utils/request
export default {name: LoginPage,async created () {const res await request.get(/captcha/image)console.log(res)}
}13、图形验证码功能完成 遇到的问题res.data.xxx undefined 1关于axios返回结果 前端想引用返回数值里的某一项结果但是却一直显示引用的结果是undefined (2)问题分析 在浏览器进行断点调试后知道之所以访问不到数据是因为axios返回的时候对返回结果多封装了一层data。而我返回的数据里面也有一个data对象导致我在点data的时候访问的是其外层封装的data而不是里面具体的我想要的那层data数据。 (3)处理方法 我们只需要访问data里面的data数据就行啦
准备数据获取图形验证码后存储图片路径存储图片唯一标识
script
import request from /utils/request
export default {name: LoginPage,data () {return {picCode: , // 用户输入的图形验证码picKey: , // 将来请求传递的图形验证码唯一标识picUrl: // 存储请求渲染的图片地址}},async created () {this.getPicCode()},methods: {// 获取图形验证码async getPicCode () {// const res await request.get(/captcha/image)// console.log(res.data)// console.log(res.data.data.base64)const { data: { data: { base64, key } } } await request.get(/captcha/image)// console.log(base64, key)this.picUrl base64 // 存储地址this.picKey key // 存储唯一标识}}
}
/script动态渲染图形验证码并且点击时要重新刷新验证码
div classform-iteminput v-modelpicCode classinp maxlength5 placeholder请输入图形验证码 typetextimg v-ifpicUrl :srcpicUrl clickgetPicCode alt/div14、api 接口模块 -封装图片验证码接口 新建 api/login.js 提供获取图形验证码 Api 函数
import request from /utils/request// 获取图形验证码
export const getPicCode () {return request.get(/captcha/image)
}login/index.vue页面中调用测试
async getPicCode () {const { data: { base64, key } } await getPicCode()this.picUrl base64this.picKey key
},15、Toast 轻提示 两种使用方式
导入调用 ( 组件内 或 非组件中均可 )
import { Toast } from vant;
Toast(提示内容);通过this直接调用 ( **组件内 **)
main.js 注册绑定到原型
import { Toast } from vant;
Vue.use(Toast)this.$toast(提示内容)16、短信验证倒计时 (1) 倒计时基础效果
准备 data 数据
data () {return {totalSecond: 60, // 总秒数second: 60, // 倒计时的秒数timer: null // 定时器 id}
},给按钮注册点击事件
button clickgetCode{{ second totalSecond ? 获取验证码 : second 秒后重新发送}}
/button开启倒计时时
async getCode () {if (!this.timer this.second this.totalSecond) {// 开启倒计时this.timer setInterval(() {this.second--if (this.second 1) {clearInterval(this.timer)this.timer nullthis.second this.totalSecond}}, 1000)// 发送请求获取验证码this.$toast(发送成功请注意查收)}
}离开页面销毁定时器
destroyed () {clearInterval(this.timer)
}(2) 验证码请求校验处理
输入框 v-model 绑定变量
data () {return {mobile: , // 手机号picCode: // 图形验证码}
},input v-modelmobile classinp maxlength11 placeholder请输入手机号码 typetext
input v-modelpicCode classinp maxlength5 placeholder请输入图形验证码 typetextmethods中封装校验方法
// 校验输入框内容
validFn () {if (!/^1[3-9]\d{9}$/.test(this.mobile)) {this.$toast(请输入正确的手机号)return false}if (!/^\w{4}$/.test(this.picCode)) {this.$toast(请输入正确的图形验证码)return false}return true
},请求倒计时前进行校验
// 获取短信验证码
async getCode () {if (!this.validFn()) {return}...
}(3) 封装接口请求获取验证码
封装接口 api/login.js
// 获取短信验证码
export const getMsgCode (captchaCode, captchaKey, mobile) {return request.post(/captcha/sendSmsCaptcha, {form: {captchaCode,captchaKey,mobile}})
}调用接口添加提示
// 获取短信验证码
async getCode () {if (!this.validFn()) {return}if (!this.timer this.second this.totalSecond) {// 发送请求获取验证码await getMsgCode(this.picCode, this.picKey, this.mobile)this.$toast(发送成功请注意查收)// 开启倒计时...}
}17、登录功能
目标封装api登录接口实现登录功能 步骤分析
阅读接口文档封装登录接口登录前的校验 (手机号图形验证码短信验证码)调用方法发送请求成功添加提示并跳转 api/login.js 提供登录 Api 函数
// 验证码登录
export const codeLogin (mobile, smsCode) {return request.post(/passport/login, {form: {isParty: false,mobile,partyData: {},smsCode}})
}login/index.vue 登录功能
input classinp v-modelmsgCode maxlength6 placeholder请输入短信验证码 typetext
div classlogin-btn clicklogin登录/divdata () {return {msgCode: ,}
},
methods: {async login () {if (!this.validFn()) {return}if (!/^\d{6}$/.test(this.msgCode)) {this.$toast(请输入正确的手机验证码)return}await codeLogin(this.mobile, this.msgCode)this.$router.push(/)this.$toast(登录成功)}
}18、响应拦截器统一处理错误提示
目标通过响应拦截器统一处理接口的错误提示
问题每次请求都会有可能会错误就都需要错误提示
说明响应拦截器是咱们拿到数据的 第一个 数据流转站可以在里面统一处理错误。
只要不是 200, 就给默认提示抛出错误 响应拦截器是咱们拿到数据的 第一个 “数据流转站”可以在里面统一处理错误只要不是 200 默认给提示抛出错误 utils/request.js
import { Toast } from vant...// 添加响应拦截器
request.interceptors.response.use(function (response) {const res response.dataif (res.status ! 200) {Toast(res.message)return Promise.reject(res.message)}// 对响应数据做点什么return res
}, function (error) {// 对响应错误做点什么return Promise.reject(error)
})此时res res.data 所以之前res.data.xxx undefined就不会undefined了我们需要少包含一层data
19、登录权证信息存储 新建 vuex user 模块 store/modules/user.js
export default {namespaced: true,state () {return {userInfo: {token: ,userId: },}},mutations: {},actions: {}
}挂载到 vuex 上
import Vue from vue
import Vuex from vuex
import user from ./modules/userVue.use(Vuex)export default new Vuex.Store({modules: {user,}
})提供 mutations
mutations: {setUserInfo (state, obj) {state.userInfo obj},
},页面中 commit 调用
// 登录按钮校验 提交
async login () {if (!this.validFn()) {return}...const res await codeLogin(this.mobile, this.msgCode)this.$store.commit(user/setUserInfo, res.data)this.$router.push(/)this.$toast(登录成功)
}20、storage存储模块 - vuex 持久化处理 新建 utils/storage.js 封装方法
const INFO_KEY hm_shopping_info// 获取个人信息
export const getInfo () {const result localStorage.getItem(INFO_KEY)return result ? JSON.parse(result) : {token: ,userId: }
}// 设置个人信息
export const setInfo (info) {localStorage.setItem(INFO_KEY, JSON.stringify(info))
}// 移除个人信息
export const removeInfo () {localStorage.removeItem(INFO_KEY)
}vuex user 模块持久化处理
import { getInfo, setInfo } from /utils/storage
export default {namespaced: true,state () {return {userInfo: getInfo()}},mutations: {setUserInfo (state, obj) {state.userInfo objsetInfo(obj)}},actions: {}
}21、添加请求 loading 效果 请求时打开 loading
// 添加请求拦截器
request.interceptors.request.use(function (config) {// 在发送请求之前做些什么Toast.loading({message: 请求中...,forbidClick: true,loadingType: spinner,duration: 0})return config
}, function (error) {// 对请求错误做些什么return Promise.reject(error)
})响应时关闭 loading
// 添加响应拦截器
request.interceptors.response.use(function (response) {const res response.dataif (res.status ! 200) {Toast(res.message)return Promise.reject(res.message)} else {// 清除 loading 中的效果Toast.clear()}// 对响应数据做点什么return res
}, function (error) {// 对响应错误做点什么return Promise.reject(error)
})22、页面访问拦截 所有的路由一旦被匹配到都会先经过全局前置守卫只有全局前置守卫放行才会真正解析渲染组件才能看到页面内容 访问权限页面时拦截或放行的关键点 → 用户是否有登录权证 token store - index.js
import Vue from vue
import Vuex from vuex
import user from ./modules/userVue.use(Vuex)export default new Vuex.Store({state: {},getters: {token (state) {return state.user.userInfo.token}},mutations: {},actions: {},modules: {user}
})const authUrl [/pay, /myorder]
router.beforeEach((to, from, next) {const token store.getters.tokenif (!authUrl.includes(to.path)) {next()return}if (token) {next()} else {next(/login)}
})23、首页 - 静态结构准备 动态渲染 1静态结构准备

this.$router.replace(url)30、加入购物车 - 封装接口进行请求
目标封装接口进行加入购物车的请求
api/cart.js 中封装接口页面中调用接口遇到问题接口需要传递 token解决问题请求拦截器统一携带 token小图标定制 1.封装接口 api/cart.js
// 加入购物车
export const addCart (goodsId, goodsNum, goodsSkuId) {return request.post(/cart/add, {goodsId,goodsNum,goodsSkuId})
}2.页面中调用请求
data () {return {cartTotal: 0}
},async addCart () {...const { data } await addCart(this.goodsId, this.addCount, this.detail.skuList[0].goods_sku_id)this.cartTotal data.cartTotalthis.$toast(加入购物车成功)this.showPannel false
},3.请求拦截器中统一携带 token
// 自定义配置 - 请求/响应 拦截器
// 添加请求拦截器
instance.interceptors.request.use(function (config) {...const token store.getters.tokenif (token) {config.headers[Access-Token] tokenconfig.headers.platform H5}return config
}, function (error) {// 对请求错误做些什么return Promise.reject(error)
})4.准备小图标
div classicon-cartspan v-ifcartTotal 0 classnum{{ cartTotal }}/spanvan-icon nameshopping-cart-o /span购物车/span
/div5.定制样式

import Vuex from vuex
import user from ./modules/user
import cart from ./modules/cartVue.use(Vuex)export default new Vuex.Store({getters: {token: state state.user.userInfo.token},modules: {user,cart}
})封装 API 接口 api/cart.js
// 获取购物车列表数据
export const getCartList () {return request.get(/cart/list)
}封装 action 和 mutation
mutations: {setCartList (state, newList) {state.cartList newList},
},
actions: {async getCartAction (context) {const { data } await getCartList()data.list.forEach(item {item.isChecked true})context.commit(setCartList, data.list)}
},页面中 dispatch 调用
computed: {isLogin () {return this.$store.getters.token}
},
created () {if (this.isLogin) {this.$store.dispatch(cart/getCartAction)}

}(6)购物车 - 数字框修改数量
封装 api 接口
// 更新购物车商品数量
export const changeCount (goodsId, goodsNum, goodsSkuId) {return request.post(/cart/update, {goodsId,goodsNum,goodsSkuId})
}页面中注册点击事件传递数据
CountBox :valueitem.goods_num inputvalue changeCount(value, item.goods_id, item.goods_sku_id)/CountBoxchangeCount (value, goodsId, skuId) {this.$store.dispatch(cart/changeCountAction, {value,goodsId,skuId})
},提供 action 发送请求 commit mutation
mutations: {changeCount (state, { goodsId, value }) {const obj state.cartList.find(item item.goods_id goodsId)obj.goods_num value}
},
actions: {async changeCountAction (context, obj) {const { goodsId, value, skuId } objcontext.commit(changeCount, {goodsId,value})await changeCount(goodsId, value, skuId)},
}(7)购物车 - 编辑切换状态
data 提供数据, 定义是否在编辑删除的状态
data () {return {isEdit: false}
},注册点击事件修改状态
span classedit clickisEdit !isEditvan-icon nameedit /编辑
/span底下按钮根据状态变化
div v-if!isEdit :class{ disabled: selCount 0 } classgoPay去结算{{ selCount }}

div v-else :class{ disabled: selCount 0 } classdelete删除/div监视编辑状态动态控制复选框状态
watch: {isEdit (value) {if (value) {this.$store.commit(cart/toggleAllCheck, false)} else {this.$store.commit(cart/toggleAllCheck, true)}}
}(8)购物车 - 删除功能完成
查看接口封装 API ( 注意此处 id 为获取回来的购物车数据的 id )
// 删除购物车
export const delSelect (cartIds) {return request.post(/cart/clear, {cartIds})
}注册删除点击事件
div v-else :class{ disabled: selCount 0 } clickhandleDel classdelete删除({{ selCount }})
/divasync handleDel () {if (this.selCount 0) returnawait this.$store.dispatch(cart/delSelect)this.isEdit false

}
/style(2) 获取收货地址列表
1 封装获取地址的接口
import request from /utils/request// 获取地址列表
export const getAddressList () {return request.get(/address/list)
}2 页面中 - 调用获取地址
data () {return {addressList: []}
},
computed: {selectAddress () {// 这里地址管理不是主线业务直接获取默认第一条地址return this.addressList[0] }
},
async created () {this.getAddressList()
},
methods: {async getAddressList () {const { data: { list } } await getAddressList()this.addressList list}
}3 页面中 - 进行渲染
computed: {longAddress () {const region this.selectAddress.regionreturn region.province region.city region.region this.selectAddress.detail}
},div classinfo v-ifselectAddress?.address_iddiv classinfo-contentspan classname{{ selectAddress.name }}/spanspan classmobile{{ selectAddress.phone }}/span/divdiv classinfo-address{{ longAddress }}/div
/div33、订单结算台 - 确认订单信息 订单结算 - 封装通用接口
思路分析: 这里的订单结算有两种情况 购物车结算需要两个参数 ① mode“cart” ② cartIds“cartId, cartId” 立即购买结算需要三个参数 ① mode“buyNow” ② goodsId“商品id” ③ goodsSkuId“商品skuId”
都需要跳转时将参数传递过来 封装通用 API 接口 api/order
import request from /utils/requestexport const checkOrder (mode, obj) {return request.get(/checkout/order, {params: {mode,delivery: 0,couponId: 0,isUsePoints: 0,...obj}})
}34、订单结算台 - 购物车结算 订单结算 - 购物车结算
1 跳转时传递查询参数
layout/cart.vue
div clickgoPay结算({{ selCount }})/divgoPay () {if (this.selCount 0) {this.$router.push({path: /pay,query: {mode: cart,cartIds: this.selCartList.map(item item.id).join(,)}})}
}2 页面中接收参数, 调用接口获取数据
data () {return {order: {},personal: {}}
},computed: {mode () {return this.$route.query.mode},cartIds () {return this.$route.query.cartIds}
}async created () {this.getOrderList()
},async getOrderList () {if (this.mode cart) {const { data: { order, personal } } await checkOrder(this.mode, { cartIds: this.cartIds })this.order orderthis.personal personal}
}3 基于数据进行渲染
!-- 订单明细 --
div classpay-list v-iforder.goodsListdiv classlistdiv classgoods-item v-foritem in order.goodsList :keyitem.goods_iddiv classleftimg :srcitem.goods_image alt //divdiv classrightp classtit text-ellipsis-2{{ item.goods_name }}/pp classinfospan classcountx{{ item.total_num }}/spanspan classprice¥{{ item.total_pay_price }}/span/p/div/div/divdiv classflow-num-boxspan共 {{ order.orderTotalNum }} 件商品合计/spanspan classmoney{{ order.orderTotalPrice }}/span/divdiv classpay-detaildiv classpay-cellspan订单总金额/spanspan classred{{ order.orderTotalPrice }}/span/divdiv classpay-cellspan优惠券/spanspan无优惠券可用/span/divdiv classpay-cellspan配送费用/spanspan v-if!selectAddress请先选择配送地址/spanspan v-else classred0.00/span/div/div!-- 支付方式 --div classpay-wayspan classtit支付方式/spandiv classpay-cellspanvan-icon namebalance-o /余额支付可用 ¥ {{ personal.balance }} 元/span!-- span请先选择配送地址/span --span classredvan-icon namepassed //span/div/div!-- 买家留言 --div classbuytipstextarea placeholder选填买家留言50字内 name id cols30 rows10/textarea/div
/div!-- 底部提交 --
div classfooter-fixeddiv classleft实付款span{{ order.orderTotalPrice }}/span/divdiv classtipsbtn提交订单/div
/div35、订单结算台 - 立即购买结算 订单结算 - 立即购买结算
1 点击跳转传参
prodetail/index.vue
div classbtn v-ifmode buyNow clickgoBuyNow立刻购买/divgoBuyNow () {this.$router.push({path: /pay,query: {mode: buyNow,goodsId: this.goodsId,goodsSkuId: this.detail.skuList[0].goods_sku_id,goodsNum: this.addCount}})
}2 计算属性处理参数
computed: {...goodsId () {return this.$route.query.goodsId},goodsSkuId () {return this.$route.query.goodsSkuId},goodsNum () {return this.$route.query.goodsNum}
}3 基于请求时携带参数发请求渲染
async getOrderList () {...if (this.mode buyNow) {const { data: { order, personal } } await checkOrder(this.mode, {goodsId: this.goodsId,goodsSkuId: this.goodsSkuId,goodsNum: this.goodsNum})this.order orderthis.personal personal}
}mixins 复用 - 处理登录确认框的弹出
1 新建一个 mixin 文件 mixins/loginConfirm.js
export default {// 此处编写的就是 Vue组件实例的 配置项通过一定语法可以直接混入到组件内部// data methods computed 生命周期函数 ...// 注意点// 1.如果此处 和 组件内提供了同名的 data 和 methods ,则组件内优先级更高// 2.如果编写了生命周期函数则mixins中的生命周期函数 和 页面的生命周期函数会用数组管理统一执行methods: {// 是否需要弹登录确认框// (1) 需要返回 true并直接弹出登录确认框// (2) 不需要返回 falseloginConfirm () {if (!this.$store.getters.token) {this.$dialog.confirm({title: 温馨提示,message: 此时需要先登录才能继续操作哦,confirmButtonText: 去登陆,cancelButtonText: 再逛逛}).then(() {// 如果希望跳转到登录 登录后能回跳回来需要在跳转去携带参数 (当前的路径地址)// this.$route.fullPath (会包含查询参数)this.$router.replace({path: /login,query: {backUrl: this.$route.fullPath}})}).catch(() {})return true}return false}}
}
2 页面中导入混入方法
import loginConfirm from /mixins/loginConfirmexport default {name: ProDetail,mixins: [loginConfirm],...
}3 页面中调用 混入的方法
async addCart () {if (this.loginConfirm()) {return}const { data } await addCart(this.goodsId, this.addCount, this.detail.skuList[0].goods_sku_id)this.cartTotal data.cartTotalthis.$toast(加入购物车成功)this.showPannel falseconsole.log(this.cartTotal)
},goBuyNow () {if (this.loginConfirm()) {return}this.$router.push({path: /pay,query: {mode: buyNow,goodsId: this.goodsId,goodsSkuId: this.detail.skuList[0].goods_sku_id,goodsNum: this.addCount}})
}36、提交订单并支付
目标封装 API 请求方法提交订单并支付 核心步骤
封装通用请求方法买家留言绑定注册事件调用方法提交订单并支付 1 封装 API 通用方法统一余额支付
// 提交订单
export const submitOrder (mode, params) {return request.post(/checkout/submit, {mode,delivery: 10, // 物流方式 配送方式 (10快递配送 20门店自提)couponId: 0, // 优惠券 idpayType: 10, // 余额支付isUsePoints: 0, // 是否使用积分...params})
}2 买家留言绑定
data () {return {remark: }
},
div classbuytipstextarea v-modelremark placeholder选填买家留言50字内 name id cols30 rows10/textarea
/div3 注册点击事件提交订单并支付
div classtipsbtn clicksubmitOrder提交订单/div// 提交订单
async submitOrder () {if (this.mode cart) {await submitOrder(this.mode, {remark: this.remark,cartIds: this.cartIds})}if (this.mode buyNow) {await submitOrder(this.mode, {remark: this.remark,goodsId: this.goodsId,goodsSkuId: this.goodsSkuId,goodsNum: this.goodsNum})}this.$toast.success(支付成功)this.$router.replace(/myorder)
}37、订单管理 个人中心 (快速实现) 1个人中心 - 基本渲染
1 封装获取个人信息 - API接口
import request from /utils/request// 获取个人信息
export const getUserInfoDetail () {return request.get(/user/info)
}2 调用接口获取数据进行渲染
templatediv classuserdiv classhead-page v-ifisLogindiv classhead-imgimg src/assets/default-avatar.png alt //divdiv classinfodiv classmobile{{ detail.mobile }}/divdiv classvipvan-icon namediamond-o /普通会员/div/div/divdiv v-else classhead-page click$router.push(/login)div classhead-imgimg src/assets/default-avatar.png alt //divdiv classinfodiv classmobile未登录/divdiv classwords点击登录账号/div/div/divdiv classmy-assetdiv classasset-leftdiv classasset-left-itemspan{{ detail.pay_money || 0 }}/spanspan账户余额/span/divdiv classasset-left-itemspan0/spanspan积分/span/divdiv classasset-left-itemspan0/spanspan优惠券/span/div/divdiv classasset-rightdiv classasset-right-itemvan-icon namebalance-pay /span我的钱包/span/div/div/divdiv classorder-navbardiv classorder-navbar-item click$router.push(/myorder?dataTypeall)van-icon namebalance-list-o /span全部订单/span/divdiv classorder-navbar-item click$router.push(/myorder?dataTypepayment)van-icon nameclock-o /span待支付/span/divdiv classorder-navbar-item click$router.push(/myorder?dataTypedelivery)van-icon namelogistics /span待发货/span/divdiv classorder-navbar-item click$router.push(/myorder?dataTypereceived)van-icon namesend-gift-o /span待收货/span/div/divdiv classservicediv classtitle我的服务/divdiv classcontentdiv classcontent-itemvan-icon namerecords /span收货地址/span/divdiv classcontent-itemvan-icon namegift-o /span领券中心/span/divdiv classcontent-itemvan-icon namegift-card-o /span优惠券/span/divdiv classcontent-itemvan-icon namequestion-o /span我的帮助/span/divdiv classcontent-itemvan-icon namebalance-o /span我的积分/span/divdiv classcontent-itemvan-icon namerefund-o /span退换/售后/span/div/div/divdiv classlogout-btnbutton退出登录/button/div/div

}
/style2个人中心 - 退出功能
1 注册点击事件
button clicklogout退出登录/button2 提供方法
methods: {logout () {this.$dialog.confirm({title: 温馨提示,message: 你确认要退出么}).then(() {this.$store.dispatch(user/logout)}).catch(() {})}
}actions: {logout (context) {context.commit(setUserInfo, {})context.commit(cart/setCartList, [], { root: true })}
},38、打包发布 39、打包优化路由懒加载
目标配置路由懒加载实现打包优化 说明当打包构建应用时JavaScript 包会变得非常大影响页面加载。如果我们能把不同路由对应的组件分割成不同的代码块然后当路由被访问的时候才加载对应组件这样就更加高效了。 官方链接
