}
</style>

渲染数据

在这里插入图片描述

准备接口

import request from '@/utils/http'
export const getOrderAPI = (id) => {return request({url: `/member/order/${id}`})
}

获取数据渲染内容

<script setup>
import { getOrderAPI } from '@/apis/pay'
import { onMounted, ref } from 'vue'
import { useRoute } from 'vue-router'
// 获取订单数据
const route = useRoute()
const payInfo = ref({})
const getPayInfo = async () => {const res = await getOrderAPI(route.query.id)payInfo.value = res.result
}
onMounted(() => getPayInfo())</script><template><div class="xtx-pay-page"><div class="container"><!-- 付款信息 --><div class="pay-info"><span class="icon iconfont icon-queren2"></span><div class="tip"><p>订单提交成功！请尽快完成支付。</p><p>支付还剩 <span>{{ formatTime }}</span>, 超时后将取消订单</p></div><div class="amount"><span>应付总额：</span><span>¥{{ payInfo.payMoney?.toFixed(2) }}</span></div></div><!-- 付款方式 --><div class="pay-type"><p class="head">选择以下支付方式付款</p><div class="item"><p>支付平台</p><a class="btn wx" href="javascript:;"></a><a class="btn alipay" :href="payUrl"></a></div><div class="item"><p>支付方式</p><a class="btn" href="javascript:;">招商银行</a><a class="btn" href="javascript:;">工商银行</a><a class="btn" href="javascript:;">建设银行</a><a class="btn" href="javascript:;">农业银行</a><a class="btn" href="javascript:;">交通银行</a></div></div></div></div>
</template>

实现支付功能

支付业务流程
在这里插入图片描述
支付携带参数

//跳转支付
//携带订单id以及回调地址跳转到支付地址
// 支付地址
const baseURL = 'http://pcapi-xiaotuxian-front-devtest.itheima.net/'
const backURL = 'http://127.0.0.1:5173/paycallback'
const redirectUrl = encodeURIComponent(backURL)
const payUrl = `${baseURL}pay/aliPay?orderId=${route.query.id}&redirect=${redirectUrl}`

支付结果展示

在这里插入图片描述

准备模版payBack

<script setup></script>
<template><div class="xtx-pay-page"><div class="container"><!-- 支付结果 --><div class="pay-result"><span class="iconfont icon-queren2 green"></span><span class="iconfont icon-shanchu red"></span><p class="tit">支付成功</p><p class="tip">我们将尽快为您发货，收货期间请保持手机畅通</p><p>支付方式：<span>支付宝</span></p><p>支付金额：<span>¥200.00</span></p><div class="btn"><el-button type="primary" style="margin-right:20px">查看订单</el-button><el-button>进入首页</el-button></div><p class="alert"><span class="iconfont icon-tip"></span>温馨提示：小兔鲜儿不会以订单异常、系统升级为由要求您点击任何网址链接进行退款操作，保护资产、谨慎操作。</p></div></div></div>
</template><style scoped lang="scss">
.pay-result {padding: 100px 0;background: #fff;text-align: center;margin-top: 20px;>.iconfont {font-size: 100px;}.green {color: #1dc779;}.red {color: $priceColor;}.tit {font-size: 24px;}.tip {color: #999;}p {line-height: 40px;font-size: 16px;}.btn {margin-top: 50px;}.alert {font-size: 12px;color: #999;margin-top: 50px;}
}
</style>

绑定路由

import PayBack from '@/views/Pay/PayBack.vue'
{path: 'paycallback', // 注意路径，必须是paycallbackcomponent: PayBack
}

渲染数据

<script setup>
import { getOrderAPI } from '@/apis/pay'
import { onMounted, ref } from 'vue'
import { useRoute } from 'vue-router'
const route = useRoute()
const orderInfo = ref({})
const getOrderInfo = async () => {const res = await getOrderAPI(route.query.orderId)orderInfo.value = res.result
}
onMounted(() => getOrderInfo())
</script>
<template><div class="xtx-pay-page"><div class="container"><!-- 支付结果 --><div class="pay-result"><!-- 路由参数获取到的是字符串而不是布尔值 --><span class="iconfont icon-queren2 green" v-if="$route.query.payResult === 'true'"></span><span class="iconfont icon-shanchu red" v-else></span><p class="tit">支付{{ $route.query.payResult === 'true' ? '成功' : '失败' }}</p><p class="tip">我们将尽快为您发货，收货期间请保持手机畅通</p><p>支付方式：<span>支付宝</span></p><p>支付金额：<span>¥{{ orderInfo.payMoney?.toFixed(2) }}</span></p><div class="btn"><el-button type="primary" style="margin-right:20px">查看订单</el-button><el-button>进入首页</el-button></div><p class="alert"><span class="iconfont icon-tip"></span>温馨提示：小兔鲜儿不会以订单异常、系统升级为由要求您点击任何网址链接进行退款操作，保护资产、谨慎操作。</p></div></div></div>
</template>

封装支付倒计时

在这里插入图片描述
理解需求
编写一个函数useCountDown可以把秒数格式化为倒计时的显示状态
1️⃣formatTime为显示的倒计时时间
2️⃣start是倒计时启动函数，调用时可以设置初始值并且开始倒计时

实现思路分析
在这里插入图片描述
倒计时逻辑函数封装

// 封装倒计时逻辑函数
import { computed, onUnmounted, ref } from 'vue'
import dayjs from 'dayjs'
export const useCountDown = () => {// 1. 响应式的数据let timer = nullconst time = ref(0)// 格式化时间 为 xx分xx秒const formatTime = computed(() => dayjs.unix(time.value).format('mm分ss秒'))// 2. 开启倒计时的函数const start = (currentTime) => {// 开始倒计时的逻辑// 核心逻辑的编写：每隔1s就减一time.value = currentTimetimer = setInterval(() => {time.value--}, 1000)}// 组件销毁时清除定时器onUnmounted(() => {timer && clearInterval(timer)})return {formatTime,start}
}

页面使用

import { useCountDown } from '@/composables/useCountDown'
const { formatTime, start } = useCountDown()
// 获取订单数据
const route = useRoute()
const payInfo = ref({})
const getPayInfo = async () => {const res = await getOrderAPI(route.query.id)payInfo.value = res.result// 初始化倒计时秒数start(res.result.countdown)
}
onMounted(() => getPayInfo())<template><div class="tip"><p>订单提交成功！请尽快完成支付。</p><p>支付还剩 <span>{{ formatTime }}</span>, 超时后将取消订单</p></div>
</template>
