获取节点JS中的mongo Pool连接状态

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

const url = 'mongodb://localhost:27017'; // MongoDB的URL
const options = {
  useNewUrlParser: true, // 使用新的URL解析器
  useUnifiedTopology: true, // 使用新的服务器发现和监视引擎
  poolSize: 10 // 连接池的大小
};

const pool = new MongoClient(url, options);

const connectionStatus = pool.isConnected() ? '已连接' : '未连接';
console.log('连接状态：', connectionStatus);

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

const url = 'mongodb://localhost:27017';
const options = {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  poolSize: 10
};

const pool = new MongoClient(url, options);

const connectionStatus = pool.isConnected() ? '已连接' : '未连接';
