推荐答案

您应单独创建对象并保存.您不能传递这样的数组.在

You should individually create objects and save them. You can't pass an array like that. Use something in the lines of

var laptopData = [...];
for(var laptopItem in laptopData){
    new Laptop(laptopData[laptopItem])
      .save()
      .catch((err)=>{
        console.log(err.message);
      });
}
