连接到Atlas Mongo数据库 [英] connecting to atlas mongo database

问题描述

我正在使用node.Js，expressjs mongodb和Atlas

I'm using node.Js, expressjs mongodb and Atlas

var Db     = require('mongodb').Db;
var Server = require('mongodb').Server;

以上方法对我不起作用.通过使用地图集数据库.现在为您提供了三个带有三个不同主机/URL的节点，这里的问题是当我尝试连接到 mongodb.server 时，它只要求一个主机名(或允许它添加许多主机名).但我只是不知道如何)

the above method is not working for me. by using atlas database. you are given three nodes with three different host/Url now the problem here is that when I try to connect to mongodb.server it only ask for one host name (or its allowed to add many but I just don't know how)

我的问题是，我该如何进行这项工作?就像我如何将3个不同的网址合并在一起，并让1个端口进入.并连接到数据库服务器

my question would be, how can I make this work? like how can I join together 3 different Url and let 1 port let it in. and connect to database server

MongoDB地图集为您提供了

MongoDB Atlas provides you with a MongoDB Connection URI. The connection string should contain host(s) information.

您还可以在手册

MongoDB 3.4版及更早版本:

MongoDB Version 3.4 and earlier:

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

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

var uri = "mongodb://user:[e-mail]:27017,mycluster0-shard-00-01.mongodb.net:27017,mycluster0-shard-00-02.mongodb.net:27017/admin?ssl=true&replicaSet=Mycluster0-shard-0&authSource=admin";
MongoClient.connect(uri, function(err, db) {
  db.close();
});
