node.js - 如何使用 mongoose 将后端 nodejs 连接到 mongodb atlas？

问题描述

我正在尝试连接到 cloud.mongodb.com。但是在运行时出现错误。

const express = require('express');
const cors = require('cors');
const bodyParser = require("body-parser");
const logger = require('morgan');
const Data =  require("./data");
const mongoose = require("mongoose");


const API_PORT = 5000;

/// database config
const DB_KEY = "mongodb+srv://twituet:<mypassWord>@cluster0-ziifr.mongodb.net/test?retryWrites=true";

mongoose
  .connect(
    DB_KEY, {useNewUrlParser: true}
  )
  .then(() => {
    console.log("Connected to database!");
  })
  .catch((error) => {
    console.log("Connection failed!");
    console.log(error);
  });

但我收到错误：
