我的 node 应用程序给了我这个消息
我已经在IP白名单上添加了我当前的IP地址和0.0.0.0.
下面是错误消息的图片和我为连接它而编写的代码.
var express = require('express');
var bodyparser = require('body-parser');
var mongoose = require('mongoose');
var app = express();
app.use(bodyparser.json());
mongoose
.connect("mongodb+srv://<username:password>@my-cluster.mongodb.net/test?retryWrites=true&w=majority",
{ useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true })
.then(() => console.log( 'Database Connected' ))
.catch(err => console.log( err ));
app.listen(3003)
这是我在运行nodemon后收到的错误.
