在mongodb-atlas上无法连接到mongodb

Question

尝试连接到mongodb-atlas上的mongodb免费数据库 我几乎尝试了所有操作检查了文档，更改了网址，更改了密码，甚至删除了用户并创建了新用户，但仍然无法解决问题

这是myurl.js文件

module.exports = {
    mongoURL: "mongodb+srv://nansDB:nansDB123@nodecluster-qs6cv.mongodb.net/test?retryWrites=true&w=majority",
    secret: "mystrongsecret"
}

这是我的index.js文件

const express = require('express');
const mongoose = require('mongoose');
const app = express();

//mongodb Configuration
const db = require('./setup/myurl').mongoURL;

//attempt to connect to database
mongoose.connect(db,  { useNewUrlParser: true })
        .then(()=> console.log('MongoDb Connect successfully'))
        .catch(err => console.log(err));

const port = process.env.PORT || 3000;

这是我每次尝试运行时都会遇到的错误行

它解决了由于连接问题[重新连接到wifi]实际上我列入白名单的ip被更改的问题。尽管我的建议是检查您列入白名单的IP是否存在。
