Javascript 猫鼬通过操纵数据表现得很怪异

我挠了差不多四个小时的头。如您所见，我刚刚用

Mongoose

查询了

MongoDB

，我得到了结果，但它似乎在某种程度上

数据

被操纵了！我不确定是

缓冲区溢出

还是

下溢

还是其他原因。 以下是我的简化nodejs代码：

let mongoose = require("mongoose");


mongoose.connect("mongodb://localhost:27017/shop", {}).then(() => {
  let schema = new mongoose.Schema({
    categoryId: {
      type: Number,
      required: true,
    },
    products: {
      shirt: {
        type: String,
        required: true,
      },
      glove: {
        type: String,
        required: true,
      },
      mitten: {
        type: String,
        required: true,
      },
      glasses: {
        type: String,
        required: true,
      },
    },
  });
  let Model = mongoose.model("Model", schema, "services_products");
  Model.findOne({ categoryId: { $exists: false } }).then((data) => {
    console.log("data: ", data);
    console.log("products: ", typeof data.products, data.products);
    console.log("products keys: ", Object.keys(data.products));
    console.log("products values: ", Object.values(data.products));
  });
});

以下是控制台日志：

  (node:15151) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.
(node:15151) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
  data:  {
  products: {
    sunGlasess: 'MAIN_STORE',
      normalGlasses: 'MAIN_STORE',
      smokeGlasses: 'MAIN_STORE',
      sportGlasses: 'MAIN_STORE'
  },
  _id: 5fe1d3ad223ac40b32038415
}
products:  object {
  sunGlasess: 'MAIN_STORE',
    normalGlasses: 'MAIN_STORE',
    smokeGlasses: 'MAIN_STORE',
    sportGlasses: 'MAIN_STORE'
}
products keys:  [ '$init', 'shirt', 'glove', 'mitten', 'glasses' ]
products values:  [ true, undefined, undefined, undefined, undefined ]

products

对象与

products键

和

products值

不匹配

注意：实际上，有一个文档将衬衫、手套、手套、眼镜作为其

产品的
键，但它们都有价值

问题是
模式
。我忘了在模式的
产品
字段中添加
太阳镜、普通眼镜、烟镜、运动眼镜
。我修改了我的模式：

let schema = new mongoose.Schema({
    categoryId: {
      type: Number,
      required: true,
    },
    products: mongoose.Schema.Types.Mixed
  });

现在，
产品可以是任何对象。
您尝试过先执行data.toObject（）时会发生什么吗？
