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。

安装了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

这是我在locallhost

中与mongoDB有关的配置

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"
        }

    }
};

Answer 1

您可以使用以下方法连接到数据库：

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

但在您的情况下，我会将mongodb://localhost/<database name>替换为mongodb://<dbuser>:<dbpassword>@ds053148.mongolab.com:53148/<database name>

Answer 2

mongoURI = 'mongodb://localhost/test';

MONGOLAB_URI = "mongodb://<admin>:<admin>@ds3232.mlab.com:23213/abcd"

mongoose.connect(MONGOLAB_URI || mongoURI)

Answer 3

module.exports = {
development: {
    db: 'mongodb://your_user_name:your_password@ds053148.mongolab.com:53148/heroku_app18934798',
    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://your_user_name:your_password@ds053148.mongolab.com:53148/heroku_app18934798',
    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://your_user_name:your_password@ds053148.mongolab.com:53148/heroku_app18934798',
    root: rootPath,
    app: {
        name: 'MEAN - A Modern Stack - Production'
    },
    facebook: {
        clientID: "APP_ID",
        clientSecret: "APP_SECRET",
        callbackURL: "http://localhost:3000/auth/facebook/callback"
    }

}
};

将其粘贴到您的config.js文件中，并将your_user_name替换为您的用户名，并将your_password替换为您的密码以获取连接。
