node.js结合mongodb

var mongodb = require('mongodb');var server = new mongodb.Server("127.0.0.1",27017,{});//本地27017端口new mongodb.Db('mongotest',server,{}).open(function(error,client){//数据库：mongotest    if(error) throw error;    var collection = new mongodb.Collection(client,'user');//表：user    collection.find(function(error,cursor){        cursor.each(function(error,doc){            if(doc){                console.log("name:"+doc.name+" age:"+doc.age);            }        });    });});

运行：
