MongoDB Atlas错误:无效的架构，预期的mongodb [英] MongoDB Atlas error: invalid schema, expected mongodb
问题描述
我正在遍历 Hello World应用程序教程在GCP中.而且我陷入了server.js步骤.
I am running through the Hello World app tutorial in GCP. And I am getting stuck at the server.js step.
server.js的代码如下:
The code of the server.js is as below:
'use strict';
const mongodb = require('mongodb');
const http = require('http');
const nconf = require('nconf');
let uri = 'mongodb+srv://my_name:<mypassword>@mydatabase-clr75.gcp.mongodb.net/test?retryWrites=true&w=majority';
if (nconf.get('mongoDatabase')) {
uri = `${uri}/${nconf.get('mongoDatabase')}`;
}
console.log(uri);
mongodb.MongoClient.connect(uri, (err, db) => {
if (err) {
throw err;
}
// Create a simple little server.
http.createServer((req, res) => {
if (req.url === '/_ah/health') {
res.writeHead(200, {
'Content-Type': 'text/plain'
});
res.write('OK');
res.end();
return;
}
const collection = db.collection('Messages');
var datetime = new Date();
const msg = {
msgDescription: '\nHello World received on ' + datetime
};
collection.insert(msg, (err) => {
if (err) {
throw err;
}
// push out a range
let msglist = '';
collection.find().toArray((err, data) => {
if (err) {
throw err;
}
data.forEach((msg) => {
msglist += `${msg.msgDescription}; `;
});
res.writeHead(200, {
'Content-Type': 'text/plain'
});
res.write('Messages received so far:\n');
res.end(msglist);
});
});
}).listen(process.env.PORT || 8080, () => {
console.log('started web process');
});
});
我收到如下错误:

我想知道这里是在读取同一错误行的其他文章后出现格式错误，所以我尝试了'...'，"..."，并且不带引号，但仍然保持错误.请指导我哪里出了问题?
I was wondering it should be the format error after reading some other posts here with the same error line, so I've tried '...', "..." and without any quotation mark but still remain error. Would please guide me where's the error?
除了URI之外，我还需要在代码内部进行其他任何修改吗?据我所知，我只需要插入自己的Atlas Connection字符串即可.
Except for the URI, is there anywhere else I also need to modify inside the code? As far as I know from the instruction I just need to insert my own Atlas Connection string.
非常感谢.
推荐答案
我有相同的错误.问题在于mongoDB Atlas中的设置和我的应用程序中的设置.
I had the same error. The problem was with setup in mongoDB Atlas and setup in my Application.
在mongoDB Atlas中:
- 创建数据库并进行收集
- 创建数据库用户
- 在"IP白名单"，网络访问"中添加您的IP地址(公共)
我的解决方案示例:
文件.env
MONGO_URI=mongodb+srv://jmendoza:your-password@cluster0-7rxkw.mongodb.net/nodeapi?retryWrites=true&w=majority
PORT=3000
文件app.js
const express = require('express');
const morgan = require('morgan');
const dotenv = require('dotenv');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const expressValidator = require('express-validator');
const { postRoutes } = require('./routes/posts');
const app = express();
const port = process.env.PORT || 3000;
dotenv.config();
// BD
mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => console.log('mongoDB, Atlas. Connected'))
.catch((err) => console.error(err));
// Middleware
app.use(morgan('dev'));
app.use(bodyParser.json());
app.use(expressValidator());
// Routes
app.use('/api/v1', postRoutes);
app.listen(port, () => {
console.log(`A NodeJS API is listining on port: ${port}`);
});
文件package.json
