记录收货列表里需要获取每一项对应的收货信息

const fetchData = async (page) => {
  if (isLoading.value == false) return uni.$u.toast('没有更多了');
  const ret = await request({
    url: '/web/orderinfo/list',
    method: 'POST',
    data: {
      orderStatus: 3,
      page,
      pageSize: 10
    },
    header: { 'Content-Type': 'application/x-www-form-urlencoded' }
  });
  if (ret.data.retData.length > 0) {
    isLoading.value = true;
    const arr = ret.data.retData;
    for (let i in arr) {
      const wuliua = await request({
        url: '/web/express/get',
        method: 'POST',
        data: {
          orderId: arr[i].list[0].orderId
          // orderId: '1233877281248772096'
        },
        header: { 'Content-Type': 'application/x-www-form-urlencoded' }
      });
      arr[i].wuliu = wuliua.data.retData;
    }
    list.value = [...list.value, ...arr];
    list.value = list.value.map((item) => ({
      ...item, // 复制当前对象
      sumOfNums: item.list.reduce((sum, it) => sum + it.num, 0) // 计算并添加sumOfNums属性
    }));
    console.log('加载待收货列表', list.value);
  } else {
    isLoading.value = false;
  }
};
