尝试使用nodeJs连接到mongodb Atlas

标签: node.js mongoose mongodb-atlas

我正在使用nodeJs + MongoDB开发一个小项目(REST API)。我已经能够在本地安装MongoDB并使用mongoose连接到它。但是出于某种原因,当我尝试使用MongoDB Atlas进行连接时,它失败了。看起来它连接但是在2秒之后,我收到一条错误消息,说明套接字关闭(参见下面的错误)。我不知道发生了什么事。我已将我的IP列入白名单,检查了我的登录信息以确保我使用的密码正确,而且我正在使用,因为我可以使用MongoDB指南针进行连接。非常感谢任何帮助。

 My current local ENV package versions are:
    nodeJs:V9.7.1
    mongoose:V6.1

=== MongoDb Atlas ===
    mongodb:3.6

以下是我用来连接数据库的代码:

var express = require('express'),
port = process.env.PORT || 3000,
mongoose = require('mongoose'),
user = require('./api/models/userModel'), 
config = require('./api/config');
bodyParser = require('body-parser');

var authRoutes = require('./api/routes/authRoutes'),
userRoutes = require('./api/routes/userRoutes'),
reviewRoutes = require('./api/routes/reviewRoutes');

const swaggerUi = require('swagger-ui-express');
const swaggerDocument = require('./swagger.json');

mongoose.Promise = global.Promise;
mongoose.connect('mongodb://user:myPass@cluster0-shard-00-00 zd6jq.mongodb.net/myDb');

app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

//Swagger Info
var options = {
    explorer : true
};

app.use('/swagger', swaggerUi.serve, swaggerUi.setup(swaggerDocument, options));
//END Swagger Info

//REGISTER ROUTES
userRoutes(app);
authRoutes(app);
reviewRoutes(app);

app.listen(port);

console.log('iReview RESTful API server listenning on port: ' + port);


module.exports = app;

var uri = 'mongodb://<usernamr>:<password>@<clustername>/<dbname>?ssl=true&replicaSet=<replica setname>&authSource=admin';

var db = mongoose.connect(uri).catch((error) => { console.log(error); });

指定副本集名称,ssl true和身份验证数据库。这是基于Atlas文档的参考。

您可以使用此代码连接到指南针和应用程序。您只需要执行以下操作:

  1. 替换集群中所有三个主要和次要分片->概述
  2. 将natours-app替换为您的集群名称。

指南针: mongodb:// babar_bahadur:PASSWORD@natours-app-shard-00-00-ybksz.mongodb.net:27017,natours-app-shard-00-01-ybksz.mongodb.net:27017,natours-app-shard- 00-02-ybksz.mongodb.net:27017/test?authSource=admin&replicaSet=natours-app1-shard-0&readPreference=primary&appname=MongoDB%20Compass&retryWrites=true&ssl=true

应用程序: mongodb:// babar_bahadur:PASSWORD@natours-app-shard-00-00-ybksz.mongodb.net:27017,natours-app-shard-00-01-ybksz.mongodb.net:27017,natours-app-shard- 00-02-ybksz.mongodb.net:27017/test?ssl=true&replicaSet=natours-app-shard-0&authSource=admin&retryWrites=true
