MongoDB find() 给出错误的对象？

Question

我正在从Order 数据库运行 Mongo 查询，旨在通过使用他的电子邮件获取特定用户的订单。这是使用 API 完成的，但我得到了带有一些不必要细节的完整对象。

代码

我在 nextJS 名称myorders 中编写了以下 API：

import Order from "../../models/Order";
import connectDB from "../../middleware/mongoose";
import jsonwebtoken from "jsonwebtoken";

const handler = async(req, res) => {
    const token = req.body.token;
    const data = jsonwebtoken.verify(token,process.env.JWT_SECRET);
    console.log(data)
    let mere_orders = Order.find({email: data.email})
    console.log("mereorders12 = ", mere_orders)
    res.status(200).json({mere_orders});
  }
  

export default connectDB(handler);

console.log("mereorders12 = ", mere_orders) 给了我这个：

mereorders12 =  Query {
  _mongooseOptions: {},
  _transforms: [],
  _hooks: Kareem { _pres: Map(0) {}, _posts: Map(0) {} },
  _executionStack: null,

    },
    '$timestamps': { createdAt: 'createdAt', updatedAt: 'updatedAt' },
    '$globalPluginsApplied': true,
    _requiredpaths: [ 'status', 'subtotal', 'address', 'products', 'orderId', 'email' ]
  },
  op: 'find',
  options: {},
  _conditions: { email: 'mohit6@test.com' },
  _fields: undefined,

  _collection: NodeCollection {
    collection: Collection {

      Promise: [Function: Promise],
      modelName: 'Order',
      _closed: false,
      opts: [Object],
      name: 'orders',
      collectionName: 'orders',
      conn: [NativeConnection],
      queue: [],
      buffer: false,
      emitter: [EventEmitter]
    },
    collectionName: 'orders'
  },
  _traceFunction: undefined,
  '$useProjection': true
}

但我应该像这样返回订单：

{  
  orders: [
    { 
      "_id":"62693ae3f7fd0b7d87c8eb9c"},
      "email":"mohit3@test.com",
      "orderId":"1389629752594",
      "paymentInfo":"No payment info",
      "products":{...},
      "address":"adasdklfasflka",
      "subtotal":4,
      "status":"Paid",
      "createdAt":{"$date":"2022-04-27T12:45:23.352Z"},
      "updatedAt":{"$date":"2022-04-27T12:45:23.352Z"},"__v":0
    },
    { 
      "_id":"62693ae3f7fd0b7d87c8eb9c"},
      "email":"mohit3@test.com",
      "orderId":"1389629752594",
      "paymentInfo":"No payment info",
      "products":{...},
      "address":"adasdklfasflka",
      "subtotal":14,
      "status":"Paid",
      "createdAt":{"$date":"2022-04-27T12:45:23.352Z"},
      "updatedAt":{"$date":"2022-04-27T12:45:23.352Z"},"__v":0
    }
  ]
}

此外，这是Order 的模型架构

const mongoose = require("mongoose");

const OrderSchema = new mongoose.Schema(
  {
    email: { type: String, required: true },
    orderId: { type: String, required: true },
    paymentInfo: { type: String, default: "No payment info" },
    products: { type: Object, required: true },
    address: { type: String, required: true },
    subtotal: { type: Number, required: true },
    status: { type: String, required: true, default: "Pending" },
  },
  { timestamps: true }
);

export default mongoose.models.Order || mongoose.model("Order", OrderSchema);

请帮忙。

Answer 1

从Model.find()，它返回Query 对象。

在example 之后，您需要异步执行查询。

let mere_orders = await Order.find({email: data.email}).exec();

或者

let mere_orders = await Order.find({email: data.email});

当您尝试将 JSON 返回为：

{
    orders: [...]
}

您应该返回如下响应：

res.status(200).json({ orders: mere_orders });
