01. 订单结算台

所谓的 “立即结算”，本质就是跳转到订单结算台，并且跳转的同时，需要携带上对应的订单参数。

而具体需要哪些参数，就需要基于 【订单结算台】 的需求来定。

(1) 静态布局

准备静态页面

<template><div class="pay"><van-nav-bar fixed title="订单结算台" left-arrow @click-left="$router.go(-1)" /><!-- 地址相关 --><div class="address"><div class="left-icon"><van-icon name="logistics" /></div><div class="info" v-if="true"><div class="info-content"><span class="name">小红</span><span class="mobile">13811112222</span></div><div class="info-address">江苏省 无锡市 南长街 110号 504</div></div><div class="info" v-else>请选择配送地址</div><div class="right-icon"><van-icon name="arrow" /></div></div><!-- 订单明细 --><div class="pay-list"><div class="list"><div class="goods-item"><div class="left"><img src="http://cba.itlike.com/public/uploads/10001/20230321/8f505c6c437fc3d4b4310b57b1567544.jpg" alt="" /></div><div class="right"><p class="tit text-ellipsis-2">三星手机 SAMSUNG Galaxy S23 8GB+256GB 超视觉夜拍系统 超清夜景 悠雾紫 5G手机 游戏拍照旗舰机s23</p><p class="info"><span class="count">x3</span><span class="price">¥9.99</span></p></div></div></div><div class="flow-num-box"><span>共 12 件商品，合计：</span><span class="money">￥1219.00</span></div><div class="pay-detail"><div class="pay-cell"><span>订单总金额：</span><span class="red">￥1219.00</span></div><div class="pay-cell"><span>优惠券：</span><span>无优惠券可用</span></div><div class="pay-cell"><span>配送费用：</span><span v-if="false">请先选择配送地址</span><span v-else class="red">+￥0.00</span></div></div><!-- 支付方式 --><div class="pay-way"><span class="tit">支付方式</span><div class="pay-cell"><span><van-icon name="balance-o" />余额支付（可用 ¥ 999919.00 元）</span><!-- <span>请先选择配送地址</span> --><span class="red"><van-icon name="passed" /></span></div></div><!-- 买家留言 --><div class="buytips"><textarea placeholder="选填：买家留言（50字内）" name="" id="" cols="30" rows="10"></textarea></div></div><!-- 底部提交 --><div class="footer-fixed"><div class="left">实付款：<span>￥999919</span></div><div class="tipsbtn">提交订单</div></div></div>
</template><script>

}
</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 class="info" v-if="selectAddress?.address_id"><div class="info-content"><span class="name">{{ selectAddress.name }}</span><span class="mobile">{{ selectAddress.phone }}</span></div><div class="info-address">{{ longAddress }}</div>
</div>

(3) 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：

1. 购物车结算，需要两个参数

   ① mode=“cart”

   ② cartIds=“cartId, cartId”

2. 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”【商品规格，如大小、颜色】

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/request'export const checkOrder = (mode, obj) => {return request.get('/checkout/order', {params: {mode,delivery: 0,couponId: 0,isUsePoints: 0,...obj}})
}

(4) 订单结算 - 购物车结算

1 跳转时，传递查询参数

layout/cart.vue

<div @click="goPay">结算({{ selCount }})</div>goPay () {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 class="pay-list" v-if="order.goodsList"><div class="list"><div class="goods-item" v-for="item in order.goodsList" :key="item.goods_id"><div class="left"><img :src="item.goods_image" alt="" /></div><div class="right"><p class="tit text-ellipsis-2">{{ item.goods_name }}</p><p class="info"><span class="count">x{{ item.total_num }}</span><span class="price">¥{{ item.total_pay_price }}</span></p></div></div></div><div class="flow-num-box"><span>共 {{ order.orderTotalNum }} 件商品，合计：</span><span class="money">￥{{ order.orderTotalPrice }}</span></div><div class="pay-detail"><div class="pay-cell"><span>订单总金额：</span><span class="red">￥{{ order.orderTotalPrice }}</span></div><div class="pay-cell"><span>优惠券：</span><span>无优惠券可用</span></div><div class="pay-cell"><span>配送费用：</span><span v-if="!selectAddress">请先选择配送地址</span><span v-else class="red">+￥0.00</span></div></div><!-- 支付方式 --><div class="pay-way"><span class="tit">支付方式</span><div class="pay-cell"><span><van-icon name="balance-o" />余额支付（可用 ¥ {{ personal.balance }} 元）</span><!-- <span>请先选择配送地址</span> --><span class="red"><van-icon name="passed" /></span></div></div><!-- 买家留言 --><div class="buytips"><textarea placeholder="选填：买家留言（50字内）" name="" id="" cols="30" rows="10"></textarea></div>
</div><!-- 底部提交 -->
<div class="footer-fixed"><div class="left">实付款：<span>￥{{ order.orderTotalPrice }}</span></div><div class="tipsbtn">提交订单</div>
</div>

(5) 订单结算 - 立即购买结算

1 点击跳转传参

prodetail/index.vue

<div class="btn" v-if="mode === 'buyNow'" @click="goBuyNow">立刻购买</div>goBuyNow () {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}
}

(6) mixins 复用 - 处理登录确认框的弹出

1 新建一个 mixin 文件 mixins/loginConfirm.js

mixin文件中可以编写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和生命周期函数

注意点：如果此处和组件内提供了同名的data或methods，则组件内优先级更高

export default{data(){return {title: '标题'}},methods(){sayHi(){}}
}

当其他组件引入mixin文件时，该组件中的data就会包含一个title属性，methods中会包含一个sayHi方法。

export default {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/loginConfirm'export 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}})
}

02. 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 class="buytips"><textarea v-model="remark" placeholder="选填：买家留言（50字内）" name="" id="" cols="30" rows="10"></textarea>
</div>

3 注册点击事件，提交订单并支付

<div class="tipsbtn" @click="submitOrder">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')
}

03. 订单管理

(1) 静态布局

1 基础静态结构

<template><div class="order"><van-nav-bar title="我的订单" left-arrow @click-left="$router.go(-1)" /><van-tabs v-model="active"><van-tab title="全部"></van-tab><van-tab title="待支付"></van-tab><van-tab title="待发货"></van-tab><van-tab title="待收货"></van-tab><van-tab title="待评价"></van-tab></van-tabs><OrderListItem></OrderListItem></div>
</template><script>
import OrderListItem from '@/components/OrderListItem.vue'
export default {name: 'OrderPage',components: {OrderListItem},data () {return {active: 0}}
}
</script><style lang="less" scoped>
.order {background-color: #fafafa;
}
.van-tabs {position: sticky;top: 0;
}
</style>

2 components/OrderListItem

<template><div class="order-list-item"><div class="tit"><div class="time">2023-07-01 12:02:13</div><div class="status"><span>待支付</span></div></div><div class="list"><div class="list-item"><div class="goods-img"><img src="http://cba.itlike.com/public/uploads/10001/20230321/c4b5c61e46489bb9b9c0630002fbd69e.jpg" alt=""></div><div class="goods-content text-ellipsis-2">Apple iPhone 14 Pro Max 256G 银色 移动联通电信5G双卡双待手机</div><div class="goods-trade"><p>¥ 1299.00</p><p>x 3</p></div></div><div class="list-item"><div class="goods-img"><img src="http://cba.itlike.com/public/uploads/10001/20230321/c4b5c61e46489bb9b9c0630002fbd69e.jpg" alt=""></div><div class="goods-content text-ellipsis-2">Apple iPhone 14 Pro Max 256G 银色 移动联通电信5G双卡双待手机</div><div class="goods-trade"><p>¥ 1299.00</p><p>x 3</p></div></div><div class="list-item"><div class="goods-img"><img src="http://cba.itlike.com/public/uploads/10001/20230321/c4b5c61e46489bb9b9c0630002fbd69e.jpg" alt=""></div><div class="goods-content text-ellipsis-2">Apple iPhone 14 Pro Max 256G 银色 移动联通电信5G双卡双待手机</div><div class="goods-trade"><p>¥ 1299.00</p><p>x 3</p></div></div></div><div class="total">共12件商品，总金额 ¥29888.00</div><div class="actions"><span v-if="false">立刻付款</span><span v-if="true">申请取消</span><span v-if="false">确认收货</span><span v-if="false">评价</span></div></div>
</template><script>
export default {}
</script><style lang="less" scoped>
.order-list-item {margin: 10px auto;width: 94%;padding: 15px;background-color: #ffffff;box-shadow: 0 0.5px 2px 0 rgba(0,0,0,.05);border-radius: 8px;color: #333;font-size: 13px;.tit {height: 24px;line-height: 24px;display: flex;justify-content: space-between;margin-bottom: 20px;.status {color: #fa2209;}}.list-item {display: flex;.goods-img {width: 90px;height: 90px;margin: 0px 10px 10px 0;img {width: 100%;height: 100%;}}.goods-content {flex: 2;line-height: 18px;max-height: 36px;margin-top: 8px;}.goods-trade {flex: 1;line-height: 18px;text-align: right;color: #b39999;margin-top: 8px;}}.total {text-align: right;}.actions {text-align: right;span {display: inline-block;height: 28px;line-height: 28px;color: #383838;border: 0.5px solid #a8a8a8;font-size: 14px;padding: 0 15px;border-radius: 5px;margin: 10px 0;}}
}
</style>

3 导入注册

import { Tab, Tabs } from 'vant'
Vue.use(Tab)
Vue.use(Tabs)

(2) 点击 tab 切换渲染

1 封装获取订单列表的 API 接口

// 订单列表
export const getMyOrderList = (dataType, page) => {return request.get('/order/list', {params: {dataType,page}})
}

2 给 tab 绑定 name 属性

<van-tabs v-model="active" sticky><van-tab name="all" title="全部"></van-tab><van-tab name="payment" title="待支付"></van-tab><van-tab name="delivery" title="待发货"></van-tab><van-tab name="received" title="待收货"></van-tab><van-tab name="comment" title="待评价"></van-tab>
</van-tabs>data () {return {active: this.$route.query.dataType || 'all',page: 1,list: []}
},

3 封装调用接口获取数据

methods: {async getOrderList () {const { data: { list } } = await getMyOrderList(this.active, this.page)list.data.forEach((item) => {item.total_num = 0item.goods.forEach(goods => {item.total_num += goods.total_num})})this.list = list.data}
},
watch: {active: {immediate: true,handler () {this.getOrderList()}}
}

4 动态渲染

<OrderListItem v-for="item in list" :key="item.order_id" :item="item"></OrderListItem><template><div class="order-list-item" v-if="item.order_id"><div class="tit"><div class="time">{{ item.create_time }}</div><div class="status"><span>{{ item.state_text }}</span></div></div><div class="list" ><div class="list-item" v-for="(goods, index) in item.goods" :key="index"><div class="goods-img"><img :src="goods.goods_image" alt=""></div><div class="goods-content text-ellipsis-2">{{ goods.goods_name }}</div><div class="goods-trade"><p>¥ {{ goods.total_pay_price }}</p><p>x {{ goods.total_num }}</p></div></div></div><div class="total">共 {{ item.total_num }} 件商品，总金额 ¥{{ item.total_price }}</div><div class="actions"><div v-if="item.order_status === 10"><span v-if="item.pay_status === 10">立刻付款</span><span v-else-if="item.delivery_status === 10">申请取消</span><span v-else-if="item.delivery_status === 20 || item.delivery_status === 30">确认收货</span></div><div v-if="item.order_status === 30"><span>评价</span></div></div></div>
</template><script>
export default {props: {item: {type: Object,default: () => {return {}}}}
}
</script>
