乐意购项目前端开发 #7

一、购物车

本地购物车

创建cartStore.js文件

创建cartStore.js文件, 将购物车列表数据存在pinia中

import { ref, computed } from "vue";
import { defineStore } from "pinia";
import { useUserStore } from "./user";
import {
  insertCartAPI,
  findNewCartListAPI,
  delCartAPI,
} from "@/api/cart/index";

export const useCartStore = defineStore(
  "cart",
  () => {
    const userStore = useUserStore();
    const isLogin = computed(() => userStore.userInfo.token);
    console.log("已经执行登录验证");
    //1.定义state - cartList
    const cartList = ref([]);
    // 2. 定义action - addCart
    const addCart = async (goods) => {
      console.log(goods);
      const { id, count } = goods;
      if (isLogin.value) {
        // 登录之后的加入购车逻辑
        await insertCartAPI({ id, count });
        const res = await findNewCartListAPI();
        cartList.value = res.data;
        console.log("cartList已经赋值");
      } else {
        console.log("cartList没有赋值");
        // 添加购物车操作
        // 已添加过 - count + 1
        // 没有添加过 - 直接push
        // 思路：通过匹配传递过来的商品对象中的id能不能在cartList中找到，找到了就是添加过
        const item = cartList.value.find((item) => goods.id === item.goodsId);
        console.log("item=" + item);
        if (item) {
          // 找到了
          item.buyCount++;
        } else {
          console.log("这里运行了");
          // 没找到
          cartList.value.push(goods);
        }
      }
    };

    // 删除购物车
    const delCart = async (goodsId) => {
      if (isLogin.value) {
        // 调用接口实现接口购物车中的删除功能
        await delCartAPI([goodsId]);
        const res = await findNewCartListAPI();
        cartList.value = res.data;
      } else {
        console.log("cartdel操作已执行");
        // 思路：
        // 1. 找到要删除项的下标值 - splice
        // 2. 使用数组的过滤方法 - filter
        const idx = cartList.value.findIndex(
          (item) => goodsId === item.goodsId
        );
        cartList.value.splice(idx, 1);
      }

    };
    //更新购物车
    const updateNewList = async () => {
      const res = await findNewCartListAPI();
      cartList.value = res.data;
      console.log("已更新购物车")
    };
    //清除购物车
    const clearCart = () => {
      cartList.value = [];
    };

    // 计算属性
    // 1. 总的数量 所有项的count之和
    const allCount = computed(() =>
      cartList.value.reduce((a, c) => a + c.buyCount, 0)
    );
    // 2. 总价 所有项的count*price之和
    const allPrice = computed(() =>
      cartList.value.reduce((a, c) => a + c.buyCount * c.goodsPrice, 0)
    );
    // 单选功能
    const singleCheck = (goodsId, selected) => {
      // 通过id找到要修改的那一项 然后把它的selected修改为传过来的selected
      const item = cartList.value.find((item) => item.goodsId === goodsId);
      item.selected = selected;
    };
    // 全选功能action
    const allCheck = (selected) => {
      // 把cartList中的每一项的selected都设置为当前的全选框状态
      cartList.value.forEach((item) => (item.selected = selected));
    };

    // 是否全选计算属性
    const isAll = computed(() => cartList.value.every((item) => item.selected));

    // 3. 已选择数量
    const selectedCount = computed(() =>
      cartList.value
        .filter((item) => item.selected)
        .reduce((a, c) => a + c.buyCount, 0)
    );
    // 4. 已选择商品价钱合计
    const selectedPrice = computed(() =>
      cartList.value
        .filter((item) => item.selected)
        .reduce((a, c) => a + c.buyCount * c.goodsPrice, 0)
    );
    
    return {
      updateNewList,
      clearCart,
      selectedPrice,
      selectedCount,
      isAll,
      allCheck,
      singleCheck,
      cartList,
      allCount,
      allPrice,
      addCart,
      delCart,
    };
  },
  {
    persist: true,
  }
);

封装接口

创建文件

import http from '@/utils/http'

// 加入购物车
export function insertCartAPI ({ id,count}) {
  return http({
    url: '/cart',
    method: 'POST',
    data:{
      "goodsId":id,
      "buyCount":count
    },
  })
}

//获取最新的购物车列表
export function findNewCartListAPI () {
  return http({
    url: '/cart',
    method: 'GET',

  })
}
//获取最新的购物车列表
export function delCartAPI (ids) {
  return http({
    url: '/cart',
    method: 'DELETE',
    data:{
      "ids":ids
    }
  })
}

前往商品详情页面 Detail\index.vue绑定事件和事件逻辑

<script setup>
import { getDetail } from "@/api/goods/index";
import { ref, onMounted } from "vue";
import { useRoute } from "vue-router";
import { useCartStore } from '@/store/cartStore';

const cartStore = useCartStore()
const route = useRoute();
const goods = ref({});
const category = ref({});
const seller = ref({});


const getGoods = async () => {
  const res = await getDetail(route.params.id);
  goods.value = res.data.good;
  category.value = res.data.category;
  seller.value = res.data.seller;
  console.log(res.data.pictureList)
  imageList.value = res.data.pictureList
};
//count
const count = ref(1)
const countChange = (count) => {
    console.log(count);
}
//添加购物车
const addCart = () => {
    //console.log(goods)

        cartStore.addCart({
            id: goods.value.id,
            name: goods.value.goodsName,
            picture: goods.value.picture1,
            price: goods.value.price,
            count: count.value,
            // attrsText: skuObj.specsText,
            selected: true
        })
    }


onMounted(() => {
  getGoods();
});
console.log(imageList);
</script>

<template>
    <!-- 数据组件 -->
    <el-input-number :min="1" v-model="count" @change="countChange" />

    <!-- 按钮组件 -->
    <div>
      <el-button size="large" class="btn" @click="addCart">
        加入购物车
      </el-button>
    </div>
</template>

2.修改LayoutHeader.vue

在views/Layout/compopnent/LayouHeader.vue中注册和使用HeaderCart组件

<script setup>
  import HeaderCart from './HeaderCart.vue'
</script>
<template>
        <!-- 头部购物车 -->
      <HeaderCart></HeaderCart>
</template>

购物车列表页面

创建文件

<script setup>
import { useCartStore } from "@/store/cartStore";
const cartStore = useCartStore();
// 单选回调
const singleCheck = (i, selected) => {
  console.log(i, selected);
  // store cartList 数组 无法知道要修改谁的选中状态？
  // 除了selected补充一个用来筛选的参数 - skuId
  cartStore.singleCheck(i.goodsId, selected);
};
// 全选
const allCheck = (selected) => {
  cartStore.allCheck(selected)
}
</script>

<template>
  <div class="lyg-cart-page">
    <div class="container m-top-20">
      <div class="cart">
        <table >
          <thead>
            <tr>
              <th width="120">
                <el-checkbox :model-value="cartStore.isAll" @change="allCheck" />

    font-size: 16px;
    font-weight: normal;
    line-height: 50px;
  }
}
</style>

二、订单信息确认页面

创建文件

创建 views/Checkout/index.vue 文件

编写代码

<script setup>
import { ref, onMounted } from "vue";
import { useCartStore } from "@/store/cartStore";
import { getCheckInfoAPI, createOrderAPI } from "@/api/order/index";
import { useRouter } from "vue-router";
const cartStore = useCartStore();
const router = useRouter();

console.log(cartStore);

const checkInfo = ref({}); // 订单对象
const curAddress = ref({}); // 地址对象
const time = ref({}); // 时间
const Time = new Date();
time.value = Time.getTime();
//控制弹窗打开
const showDialog = ref(false);

const getCheckInfo = async () => {
  const res = await getCheckInfoAPI();
  checkInfo.value = res.data;
  console.log("data数据");
  console.log(checkInfo);
  //适配默认地址
  //从地址列表中筛选出来 isDefault === 0 那一项
  const item = checkInfo.value.address.find((item) => item.isDefault === 0);
  console.log("cauraddress数据");
  curAddress.value = item;
  console.log(curAddress);
};
//切换地址
const activeAddress = ref({});

const switchAddres = (item) => {
  console.log("switchAddres运行");
  activeAddress.value = item;
};
//覆盖地址
const confirm = () => {
  curAddress.value = activeAddress.value;
  showDialog.value = false;
};




// 创建订单
const createOrder = async () => {
  const res = await createOrderAPI({
    // deliveryTimeType: 1,
    // payType: 1,
    // payChannel: 1,
    // buyerMessage: "",
    // goods: checkInfo.value.goods.map((item) => {
    //   return {
    //     goodId: item.goodsId,
    //     buyCount: item.buyCount,
    //   };
    // }),
    // addressId: curAddress.value.id,
    // goodsIds: cartStore.cartList.filter((item) => item.selected).goodsId,
    // orderid: time.getTime(),
    goods: cartStore.cartList
      .filter((item) => item.selected)
      .map((item) => {
        return {
          id: item.id,
          goodsId: item.goodsId,
          buyCount: item.buyCount,
          goodsPrice: (item.goodsPrice * item.buyCount).toFixed(2),
        };
      }),
    addressId: curAddress.value.id,
    amount: cartStore.selectedPrice,
    orderId: time.value,
  });
  console.log("已经运行到这");
  const orderId = time.value;
  console.log(orderId);
  console.log(orderId);
  cartStore.updateNewList();
  router.push({
    path: "/pay",
    query: {
      id: orderId,
    },
  });
};

onMounted(() => {
  getCheckInfo();
});

封装接口

代码模版

import http from '@/utils/http'

export function getCheckInfoAPI () {
  return http({
    url: '/order',
    method: 'GET',

  })
}
export function createOrderAPI (data) {
  return http({
    url: '/order',
    method: 'POST',
    data
  })
}

export function getOrderAPI (id) {
  return http({
    url: `/order/${id}`,
    method: 'GET',
  })
}

配置路由

routes: [
  {
    path: '/',
    component: Layout,
    children: [
      ...
      {
        path: "checkout",
        component: Checkout
      }
    ]
  }
]

生成订单

调用接口生成订单id, 并且携带id跳转到支付页

调用更新购物车列表接口，更新购物车状态

// 创建订单
const createOrder = async () => {
  const res = await createOrderAPI({
    
    goods: cartStore.cartList
      .filter((item) => item.selected)
      .map((item) => {
        return {
          id: item.id,
          goodsId: item.goodsId,
          buyCount: item.buyCount,
          goodsPrice: (item.goodsPrice * item.buyCount).toFixed(2),
        };
      }),
    addressId: curAddress.value.id,
    amount: cartStore.selectedPrice,
    orderId: time.value,
  });
  console.log("已经运行到这");
  const orderId = time.value;
  console.log(orderId);
  console.log(orderId);
  cartStore.updateNewList();
  router.push({
    path: "/pay",
    query: {
      id: orderId,
    },
  });
};

支付页面组件

创建文件 views/Pay/index.vue

编写代码

<script setup>
import { ref, onMounted } from 'vue'
import { getOrderAPI } from '@/api/order/index'
import { useRoute } from 'vue-router';
import { useCountDown } from '@/composables/useCountDown'
const { formatTime, start } = useCountDown()

const route = useRoute()
const payInfo = ref({})
console.log(route.query.id)

const getPayInfo = async () => {
  console.log("已经运行")
    console.log(route.query.id)
    const res = await getOrderAPI(route.query.id)
    payInfo.value = res.data
    start(res.data.countdown)
}
onMounted(() => { getPayInfo() })
</script>

倒计时组件

创建文件

// 封装倒计时函数
import { ref,computed, onUnmounted } from "vue"
import dayjs from "dayjs"

export const useCountDown =()=>{
    // 响应式数据
    const time = ref(0)
    let timer = null
    // 格式化事件为xx分xx秒
    const formatTime = computed(()=>dayjs.unix(time.value).format('mm分ss秒'))
    // 开启倒计时的函数
    const start =(currentTime)=>{
        // 开启倒计时的逻辑
        time.value = currentTime
        timer = setInterval(() => {
            time.value--
        }, 1000);
    }
    // 组件销毁清除定时器
    onUnmounted(() => {
        timer && clearInterval(timer)
    })
    return {
        formatTime,start
    }
}
