如何在mongoLab和Heroku服务器中使用mongo URI

Question

我正在使用MongoDb和Nodejs.Nodejs托管在Heroku服务器上,Mongodb通过Heroku附加组件在MongoLab中托管.

安装MongoLab插件后,我收到了这个URI:

mongodb://<dbuser>:<dbpassword>@ds053148.mongolab.com:53148/heroku_app18934798

我不知道如何使用这个URI,请帮帮忙？在哪里放？什么是<dbuser>:<dbpassword

这是我的配置,它与mongoDB有关 locallhost

在 server.js

var env = process.env.NODE_ENV || 'development',
    config = require('./config/config')[env],
    mongoose = require('mongoose');

var db = mongoose.connect(config.db);

在 express.js

app.use(express.session({
            secret: 'thissecret',
            key:'express.sid',
            store: new mongoStore({
                url: config.db,
                collection: 'sessions'
            })
        }));

在 config.js

module.exports = {
    development: {
        db: 'mongodb://localhost/mean-dev',
        root: rootPath,
        app: {
            name: 'MEAN - A Modern Stack - Development'
        },
        facebook: {
            clientID: "APP_ID",
            clientSecret: "APP_SECRET",
            callbackURL: "http://localhost:3000/auth/facebook/callback"
        }

    },
    test: {
        db: 'mongodb://localhost/mean-test',
        root: rootPath,
        app: {
            name: 'MEAN - A Modern Stack - Test'
        },
        facebook: {
            clientID: "APP_ID",
            clientSecret: "APP_SECRET",
            callbackURL: "http://localhost:3000/auth/facebook/callback"
        }

    },
    production: {
        db: 'mongodb://localhost/mean',
        root: rootPath,
        app: {
            name: 'MEAN - A Modern Stack - Production'
        },
        facebook: {
            clientID: "APP_ID",
            clientSecret: "APP_SECRET",
            callbackURL: "http://localhost:3000/auth/facebook/callback"
        }

    }
};

您可以使用以下命令连接到数据库：

var mongoose = require('mongoose');
mongoose.connect('mongodb://<dbuser>:<dbpassword>@ds053148.mongolab.com:53148/<database name>');

但在你的情况下我会替换mongodb://localhost/<database name>为mongodb://<dbuser>:<dbpassword>@ds053148.mongolab.com:53148/<database name>
