如何通过NodeJS MongoDB查询访问坐标值？

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017'; // MongoDB连接URL
const dbName = 'your_database_name'; // 数据库名称

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

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

  const db = client.db(dbName);

  // 在这里执行查询操作
});

const collection = db.collection('locations');

// 查询访问坐标值
collection.find({}).toArray(function(err, docs) {
  if (err) {
    console.error('Failed to query coordinates:', err);
    return;
  }

  console.log('Coordinates:', docs);
});
