Question

我正在使用nodeJs + MongoDB Atlas创建一个小项目（REST API）。我能够连接到端口，但是由于某些原因，当我尝试使用MongoDB Atlas连接失败。我已将IP地址设置为我的IP白名单中的0.0.0.0/0。不知道为什么我会收到此错误。

ERROR ON CONNECTING TO DB

    at Function.Module.runMain (module.js:693:10)
  name: 'MongoParseError',
  [Symbol(mongoErrorContextSymbol)]: {} }

下面是我的app.js文件

const express = require("express");
const bodyParser = require("body-parser");
const cors = require("cors");
const mongoose = require("mongoose");


const app = express();
const port = parseInt(process.env.PORT || 8080);
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(cors({ origin: true }));

mongoose.connect(
  "mongodb://username:password@cluster0-shard-00-00-uauyv.mongodb.net:27017,cluster0-shard-00-04-uauyv.mongodb.net:27017,cluster0-shard-00-02-uarsv.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true",
  { useNewUrlParser: true }
);

mongoose.connection.on("connected", () => {
  console.log("connected to mongodb");
});

mongoose.connection.on("error", err => {
  console.log("ERROR ON CONNECTING TO DB");
  console.log(err);
});

app.listen(port, () => {
  console.log("connected to localhost port:" + port);
});

使用Node.js连接到Mongodb Atlas时出错
