Question

我尝试使用nodejs服务器与mongodb连接并进行表达。我的猫鼬版本是5.2.0，而mongodb版本是4.0。我尝试了多种与mongodb连接的方法，但是mongod服务器只是继续监听，并且不与服务器连接，也没有创建数据库。我尝试过与mongoose以及mongoclient连接，但cmd中的mongod一直在监听并且没有建立连接。这是我的服务器代码

var express = require('express');
var mongoose = require('mongoose');

var User = require('./models/user');
var app = express();


var db = mongoose.connect("mongodb://localhost:27017/server", { useNewUrlParser: true }, function(err, response) {
    if(err) {
        console.log('There is error in connecting with mongodb');
    }
    console.log('Connection has been established.');
})

mongod in cmd

mongo在另一个窗口中

您应该将 mongodb.bat 更改为下面提到的命令：-

"C:\Program Files\MongoDB\Server\4.2\bin\mongod.exe" --dbpath "f:\mongodb\data"

无法与mongodb localhost：27017连接
