Node.js接口通过传递ObjectID查找MongoDB文档

const MongoClient = require('mongodb').MongoClient;

const url = 'mongodb://localhost:27017'; // MongoDB数据库的连接URL
const dbName = 'mydatabase'; // 数据库名称

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

  const db = client.db(dbName); // 获取数据库对象

  const collection = db.collection('mycollection'); // 获取集合对象

  const objectId = '60642fe0ac2fd437d0e0299a'; // 要查询的ObjectID

  collection.findOne({ _id: new require('mongodb').ObjectID(objectId) }, function(err, doc) {
    if (err) {
      console.error('Failed to find document:', err);
      return;
    }
    
    console.log('Found document:', doc);
    client.close(); // 关闭数据库连接
  });
});
