mongodb://127.0.0.1:27017/directConnection=true&serverSelectionTimeoutMS=2000
)http://localhost:3000/
(app.listen(3000);
)但是,我仍然收到以下错误:

我的依赖项:
"dependencies": {
"ejs": "^3.1.6",
"express": "^4.17.1",
"mongodb": "^4.0.1"
},
"devDependencies": {
"nodemon": "^2.0.7"
}
仅供引用:Node.js v17.0.1
更新: 这是我的 database.js 文件
const mongodb = require('mongodb');
const MongoClient = mongodb.MongoClient;
let database;
async function connectToDatabase() {
const client = await MongoClient.connect('mongodb://localhost:27017');
database = client.db('file-demo');
}
function getDb() {
if (!database) {
throw { message: 'Database not connected!' };
}
return database;
}
module.exports = {
connectToDatabase: connectToDatabase,
getDb: getDb,
};
这是我的 app.js:
const path = require('path');
const express = require('express');
const userRoutes = require('./routes/users');
const db = require('./data/database');
const app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use(express.urlencoded({ extended: false }));
app.use(express.static('public'));
app.use(userRoutes);
db.connectToDatabase().then(function () {
app.listen(3000);
});
最佳答案
正如@prasad_ 指出的那样,在文件中将 localhost
更改为 127.0.0.1
会有所帮助,您将在其中建立与 MongoDB 服务器的连接。
虽然它们应该被视为同义词,并且因为我能够排除一般问题(您可以在类似问题中找到答案),但这可能只是 chrome 的缓存问题,如 here .
