Question

代码示例 -

const express=require('express'),
    http=require('http'),
    handlebars=require('express-handlebars').create({defaultLayout:'main'}),
    fs=require('fs'),
    mongoose=require('mongoose'),
    uriUtil = require('mongodb-uri'),
    credentials=require('./credentials.js'),
    bodyParser=require('body-parser');

    //connect to databse
    var mongooptions = {
        server: {
            poolSize:5,
            socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } },
            replset: { socketOptions: { keepAlive: 1, connectTimeoutMS : 30000 }
        },
    };
    var mongodbUri=("mongodb://user:pwd@ds029831.mongolab.com:29831/project");
    var mongooseUri=uriUtil.formatMongoose(mongodbUri);
    mongoose.connect(mongooseUri,mongooptions);
    var conn=mongoose.connection;
    conn.on('error',function(err){
        console.log(err.message);
    });

    conn.on('connection',function() {
        var app=express();
        app.set('port',process.env.PORT);
        app.engine('handlebars',handlebars.engine);
        app.set('view engine','handlebars');
        app.use(express.static('./public'));
        app.use(bodyParser.json());
        app.use(bodyParser.urlencoded({extended: true}));
        app.use(require('express-session')({
            secret: 'intro skill',
            resave: false,
            saveUninitialized: false,
            cookie: {maxAge:900000}
        }));
        var userSchema=new mongoose.Schema({
            username: String,
            password: String,
            email   : String
        });
        var user=mongoose.model('users',userSchema);
        //routing

        function startServer(){
            http.createServer(app).listen(app.get('port'),function(){
                console.log("Server Started at port "+app.get('port'));
            });
        }

        if(require.main===module){
            startServer();
        }
        else{
            module.exports=startServer;
        }   

    });

这是我的node.js的代码。我正在使用mongolab作为mongodb 我在cloud9上运行app 当我使用mongoose连接到数据库时，由于无法连接到1％40ds029831.mongolab.com：29831 ，因此抛出错误。

应用程序正在连接到mongolab，并在身份验证（成功）后显示此错误。请帮帮我。

Answer 1

您的密码是否包含“@”字符？如果是，请将其替换为％40并再试一次，“@”字符应仅出现在主机名之前。
