MongoHQ Node.js连接URL Conection失败

我有一个工作的Node.js应用程序设置和运行良好时使用我的本地开发MongoDB与这些设置和代码：

var MongoDB = require('mongodb').Db; var Server = require('mongodb').Server; var dbPort = 27017; var dbHost = 'localhost'; var dbName = 'my-db'; var db = new MongoDB(dbName, new Server(dbHost, dbPort, {auto_reconnect: true}), {w: 1}); db.open(function(e, d){ if (e) { console.log(e); } else{ console.log('connected to database :: ' + dbName); } }); 

但是，当我尝试与我的MongoHQ URI连接，我得到一个失败连接错误。

我不确定如何使用以上代码的URI：mongodb：// username：[e-mail]：10022 / my-db。

编辑：这是我的代码的下一部分，以显示如何使用数据库variables，以防止问题：

 var accounts = db.collection('accounts'); /* login validation methods */ exports.autoLogin = function(user, pass, callback) { accounts.findOne({user:user}, function(e, o) { if (o){ o.pass == pass ? callback(o) : callback(null); } else{ callback(null); } }); } exports.manualLogin = function(user, pass, callback) { accounts.findOne({user:user}, function(e, o) { if (o == null){ callback('user-not-found'); } else{ validatePassword(pass, o.pass, function(err, res) { if (res){ callback(null, o); } else{ callback('invalid-password'); } }); } }); } 

Answer 1

尝试这个：

 var mongodb = require('mongodb'); var url = require('url'); var MONGOHQ_URL = "mongodb://username:[e-mail]:10022/my-db"; var connectionUri = url.parse(MONGOHQ_URL); var dbName = connectionUri.pathname.replace(/^\//, ''); mongodb.Db.connect(MONGOHQ_URL, function(error, client) { if (error) throw error; console.log('Connected to database :: ' + dbName); // Some code - Print collection names client.collectionNames(function(error, names){ if(error) throw error; console.log("Collections"); names.forEach(function(colData){ var colName = colData.name.replace(dbName + ".", '') console.log(colName); }); }); }); 

Answer 2

 var username = 'username'; var passwd = 'password'; /* establish the database connection */ var db = new MongoDB(dbName, new Server(dbHost, dbPort, {auto_reconnect: true}), {w: 1}); db.open(function(e, aa){ if (e) { console.log(e); } else{ aa.authenticate(username, passwd,function(err2,d){ if(d){ console.log("Database opened"); } else{ console.log(err2); } }); } });
