Javascript js mongoDb复制项提供外部数据

我有一个数组：

"data": [
        {
            "photo": "no-photo.jpg",
            "_id": "5e9aabd9c975a10a7ee48476",
            "title": "Title",
            "description": "Description",
            "phone": "77477926783",
            "fromLocation": "5e9aa8a9c975a10a7ee48474",
            "toLocation": "5e9aa8bac975a10a7ee48475",
            "price": 1000000,
            "date": "1998-02-23T00:00:00.000Z",
            "user": "5e91729f147813258ef1f373",
            "createdAt": "2020-04-18T07:27:21.743Z",
            "__v": 0,
            "courses": [],
            "id": "5e9aabd9c975a10a7ee48476"
        }
    ]

我对…循环使用

：

for (const item of res.advancedResults.data) {
  console.log(item)
}

它给出了正常的：

{
 "photo": "no-photo.jpg",
 "_id": "5e9aabd9c975a10a7ee48476",
 "title": "Title",
 "description": "Description",
 "phone": "77477926783",
 "fromLocation": "5e9aa8a9c975a10a7ee48474",
 "toLocation": "5e9aa8bac975a10a7ee48475",
 "price": 1000000,
 "date": "1998-02-23T00:00:00.000Z",
 "user": "5e91729f147813258ef1f373",
 "createdAt": "2020-04-18T07:27:21.743Z",
 "__v": 0,
 "courses": [],
 "id": "5e9aabd9c975a10a7ee48476"
}

但当我复制它时，就像：

for (const item of res.advancedResults.data) {
  console.log({...item})
}

它给出：

       strictMode: true,

如何正确复制对象？
无论何时执行任何操作，如
find
，
findOne
，等等，Mongoose都会将结果包装在Mongoose模型/文档中，该模型/文档将包含额外的元数据

如文件和-

是根据
Schema
定义编译的奇特构造函数。一
模型的实例称为。模型负责
从基础MongoDB数据库创建和读取文档

Mongoose模型为用户提供了几个静态帮助函数。每个函数都返回一个


从外观上看，您正试图将mongoose模型像普通JavaScript对象一样进行获取/解构

有两种方法可以实现这一点-

在
模型中使用
{lean:true}
选项。find（）
或
model.findOne（）
方法或使用
lean（）
方法。然而这
包含一些您可以阅读的缺点

使用
方法将文档转换为普通javascript对象

因为您正在获取mongoose模型，所以更改为
console.log（{…item.toObject（）}）
