如何在mongoose中查找数组中的文档

const mongoose = require('mongoose');

// 连接到MongoDB数据库
mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('Connected to MongoDB'))
  .catch(err => console.error('Failed to connect to MongoDB', err));

// 定义文档结构
const userSchema = new mongoose.Schema({
  name: String,
  hobbies: [String]
});

// 创建模型
const User = mongoose.model('User', userSchema);

// 查询数组中包含指定元素的文档
User.find({ hobbies: { $elemMatch: { $eq: 'reading' } } })
  .then(users => console.log(users))
  .catch(err => console.error(err));
