使用pinia 点击购物车存一个商品数据，数组，然后在购物车页面渲染出来

//carts.js

export const userCartsStore = defineStore({
  id: "carts",
  
  state: () => {
    return {
      shop:[], //存商品数组
  
  
    };
  },
     actions: {
    //添加商品的方法
    addShop(shops){
      this.shop.push(shops)
    },
    
      //添加数组
    addItemToArray(shops){
      if(!this.shop.includes(shops)){
        this.shop.push(shops)
      }
    },



  },
});


//DetailsPageView.vue  详情页

//加入购物车方法    ，shops代表当前商品
const addCard = (shops: Object) => {
  if (cartStores.shop.includes(shops)) {
    cartStores.addItemToArray(shops);
  } else {
    cartStores.addShop(shops);
  }

  console.log("11111", cartStores.shop);
