连接到 mongoDB [英] connection to mongoDB

问题描述

我是 nodeJS 和 mongodb 的新手.我无法将我的代码与 mongodb 连接.这是我的代码.当我运行这段代码时，它给了我这个，

I am a new in nodeJS and mongodb. I can not connect my code with mongodb. here is my code. when I run this code it gives me this,

(node:9160) DeprecationWarning: 当前 URL 字符串解析器是已弃用，并将在未来版本中删除.要使用新解析器，将选项 { useNewUrlParser: true } 传递给 MongoClient.connect.

(node:9160) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.

我该如何解决?

var express = require("express");
    var mongoose = require("mongoose");
    var passport = require("passport");
    var bodyParser = require("body-parser");
    var LocalStrategy = require("passport-local");
    var passportLocalMongoose = require("passport-local-mongoose");

    mongoose.connect("mongodb://localhost/mydb");

    // mongoose.connect("mongodb://localhost:27017/mydb_login", { useNewUrlParser: true })
    var app = express();

    app.set("view engine", "ejs");

推荐答案

试试吧，我想它会对你有所帮助.

Try it, I think it will help you.

let MONGOOSE = require('mongoose');    
MONGOOSE.connect('mongodb://127.0.0.1:27017/demo', (err, response)=>{
                if(err)
                    reject(err);
                else
                    resolve(null);
            });
