尝试连接到MongoDB Atlas时如何解决密码错误？

Question

I keep getting an error when trying to connect to mongdb atlas from my Node application

Here is my code

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');

const url = `mongodb+srv://username:passwordwithspeciacharacters$$!!22@cluster0-xxxxx.mongodb.net/test?retryWrites=true&w=majority`;

module.exports = {
  signup: (name, email, password) => {
    MongoClient.connect(url, (err, db) => {
      if (err) {
        console.log(err);
      } else {
        db.collection('user').insertOne({
            name: name,
            email: email,
            password: password
          },
          function(err, result) {
            assert.equal(err, null);
            console.log('Saved the user sign up details.');
          }
        );
      }
    });
  }
};

Here is the error I am getting

(node:9626) DeprecationWarning: current URL string parser is 
deprecated, and will be removed in a future version. To use the new 
parser, pass option { useNewUrlParser: true } to MongoClient.connect.
Error: Password contains an illegal unescaped character

How should I sanitize may password I am passing in?

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
const crypto = require('crypto');

const url = `mongodb+srv://username:passwordwithspeciacharacters$$!!22@cluster0-xxxxx.mongodb.net/test?retryWrites=true&w=majority`;

module.exports = {
    signup: (name, email, password) => {
        MongoClient.connect(url ,{useNewUrlParser:true}, (err, db) => {
            if (err) {
                console.log(err);
            } else {
                db.collection('user').insertOne({
                    name: name,
                    email: email,
                    password: crypto
                        .createHmac('sha256', 'secret')
                        .update(password)
                        .digest('hex')
                },
                    function (err, result) {
                        assert.equal(err, null);
                        console.log('Saved the user sign up details.');
                    }
                );
            }
        });
    }
};

// Same way you can match password while login

MongoDB passwords are URL-encoded, so you should use encodeURIComponent . Add the useNewUrlParser options object to fix the warning as well.

MongoClient.connect(encodeURIComponent(url), { useNewURLParser: true }, (err, db) => {...});
