从nodejs向mongodb对象数组添加内容

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017'; // MongoDB的连接URL
const dbName = 'mydatabase'; // 数据库名称
const collectionName = 'mycollection'; // 集合名称

// 连接到MongoDB数据库
MongoClient.connect(url, function(err, client) {
  if (err) {
    console.error('Failed to connect to MongoDB:', err);
    return;
  }

  console.log('Connected to MongoDB successfully');

  const db = client.db(dbName);
  const collection = db.collection(collectionName);

  // 创建要添加的对象
  const newObject = {
    name: 'John',
    age: 30,
    email: 'john@example.com'
  };

  // 将对象添加到集合中
  collection.insertOne(newObject, function(err, result) {
    if (err) {
      console.error('Failed to insert object:', err);
      return;
    }

    console.log('Object inserted successfully:', result.insertedId);
    client.close();
  });
});
