node.js - Node.js 应用程序不会连接到 MongoDB 服务器

Question

我似乎无法将我的 MongoDB 连接到我的 Node.js 应用程序

这是我运行 mongo status 时遇到的错误

2020-11-07T16:38:29.570-0500 E  QUERY    [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:341:17

这是我的 app.js 代码

const MongoClient = require('mongodb').MongoClient

const uri = "mongodb+srv://username:<password>@cluster0.9lxbq.mongodb.net/<MongNode>?retryWrites=true&w=majority";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
  const collection = client.db("MongNode").collection("devices");
  // perform actions on the collection object
  client.close();
});
