MongoDB find() 给出了错误的对象？

Question

我是运行来自 Order 数据库的 mongo 查询，旨在通过使用他的电子邮件 ID 获取特定用户的订单。这是使用 API 完成的，但我得到的是带有一些不必要细节的完整对象。

代码

我在nextJS名字myorders

里写了下面的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: {},

      emitter: [EventEmitter]
    },
    collectionName: 'orders'
  },
  _traceFunction: undefined,
  '$useProjection': true
}

但我应该return这样订购

{  
 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

来自 Model.find()，它 returns 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

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

当你试图 return JSON 作为：

{
    orders: [...]
}

您应该return回复如下：

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