推荐答案

getaddrinfo ENOTFOUND 表示 mongodb 客户端无法连接到给定地址.

getaddrinfo ENOTFOUND means mongodb client was not able to connect to given address.

您可以尝试在本地检查您的 mongodb 服务器，例如

You can try to check your mongodb server locally, E.G.

我在 Azure 上的 ubuntu VM 上创建了一个 mongodb 服务器作为 在 Windows 虚拟机上安装 MongoDB 显示，然后利用以下代码片段，这对我来说效果很好:

I create a mongodb server on an ubuntu VM on Azure as Install MongoDB on a Windows VM shows, then leverage the following code snippet, which works fine on my side:

var MongoClient = require('mongodb').MongoClient;
var connectionString = 'mongodb://<server_name>.cloudapp.net:27017/';
MongoClient.connect(connectionString,function(err,db){
    if(err){
        console.log(err);
        res.send(200,{message:'Something went wrong when connecting to db'});
    }else{
        db.close();
        res.send(200,{message:'Connected correctly to db'});
    }
})

更新

我在 Azure Web Apps 上创建了一个简单的测试代码项目尝试重现该问题，但在我这边运行良好，我想指出我的 env 和代码片段以供参考:

update

I create a simple test code project on Azure Web Apps try to reproduce the issue, but it works fine on my side, I'd like to point out my env and code snippet for your information:

我的依赖项:

"dependencies": {
    "jade": "*",
    "express": "~3.1.0",
    "mongoose":"*"
  },

我的带有 MongoLab connectionString 的 mongoose 代码片段:

my code snippets of mongoose with MongoLab connectionString:

exports.index = function(req, res){
    var mongoose = require('mongoose');
   mongoose.connect('mongodb://<dbuser>:<dbpassword>@ds058048.mongolab.com:58048/<dbname>');
    var db = mongoose.connection;
    db.on('error', console.error.bind(console, 'connection error:'));
    db.once('open', function (callback) {
        console.log('db open!');
        res.send(200,{message:'Connected correctly to db'});
    });
};

连接字符串显示为 MongoLab 快速入门指南 提及.

And the connectionstring is shown as Quick-Start Guide to MongoLab mentions.
