我的代码:

db.js

 module.exports = {
uri : "mongodb+srv://mithun:*******@cluster0-s089x.mongodb.net/test?retryWrites=true"}

node_route.js

node_route.js

 module.exports = function(app, db){
app.post('/notes', (req, res) => {
    const note = {text: req.body.body, title: req.body.title};
    db.collection('notes').insert(note, (err, results) => {
        if(err){
            res.send({'error': 'An error has occured'});
        } else {
            res.send(result.ops[0]);
        }
    });
 });
 };

=======================================================================index.js

 const noteRoutes = require('./note_route');
 module.exports = function(app, db){
 noteRoutes(app, db);
}

=========================================================================server.js

=========================================================================server.js

       const express = require('express');
const MongoClient = require('mongodb').MongoClient;
const bodyParser = require('body-parser');
const db = require('./config/db');
const app = express();
const port = 8000;
 app.use(bodyParser.urlencoded({extended: true}));
  MongoClient.connect(db.uri,{ useNewUrlParser: true }, (err, database) =>
  {
     if (err) return console.log(err);
     require('./app/routes')(app, database);
      app.listen(port, () => {
           console.log("We are live on " +port);
  });
 });

==========================================================================

===========================================================================

module.exports = {
uri : "mongodb+srv://mithun:m3Thun#[email protected]/test?retryWrites=true&ssl=false"

}

我尝试使用ssl = false，但错误仍然相同.

I've tried with ssl= false but the error remains same.

推荐答案

我也遇到了这个问题，在尝试创建演示应用程序时，我使用自动生成密码更新了密码，即单击了自动生成密码并将其粘贴在连接字符串中，它对我有用.

I have also faced this issue, while trying to create a demo app, I updated my password using autogenerate password, i.e I clicked on auto generate password and pasted it in connection string, it worked for me.
