MongoDB在mLab身份验证上失败

问题描述：

按照此处的步骤创建一个新的mLab帐户并创建一个数据库 http://docs.mlab .com/#create-sub .尝试使用mongo shell和mongoose Node.js模块连接到数据库，但在两种情况下都看到身份验证失败"错误.

Created a new mLab account and created a database as per the steps here http://docs.mlab.com/#create-sub . Trying to connect to the database using mongo shell and mongoose Node.js module but I see the 'Authentication Failed' errorin both cases.

在Mongo shell中，命令是，我已经仔细检查了凭据

In Mongo shell the command is, I have double checked the credentials

mongo ds012345.mlab.com:56789/dbname -u dbuser -p dbpassword

错误:

MongoError: authentication fail
at Function.MongoError.create (E:\Gatsby\notmongoose\node_modules\mongodb-core\lib\error.js:31:11)

使用猫鼬

var mongoose = require('mongoose')
, Admin = mongoose.mongo.Admin;

var uri = '<correct mongo uri here>';

var connection = mongoose.createConnection(uri,
{    
User: '<uname>',
Password: '<pwd>'
});
connection.on('open', function() {

console.log('connection established!!!');

new Admin(connection.db).listDatabases(function(err, result) {
    console.log('listDatabases succeeded');
    console.log(err);
    console.log(result); 
});

});

错误:: MongoConnect错误MongoError:身份验证失败

Error:: MongoConnect Error MongoError:authentication fail

在mLab控制台上还有其他需要做的事情吗?或者我可能做错了或遗漏的其他事情?

Is there anything else that needs to be done on the mLab console or anything else that I might be doing wrong or missing?

答

您需要在mLab帐户中为数据库创建一个新用户.然后在mlab帐户中使用该创建的用户登录.然后单击特定的数据库并单击用户".标签，请参见下图:

You needs to create a new user for the database in mLab account.and login with that created user on mlab account.then click on specific database and click on users tab, see in image below:

现在填写表格并为数据库创建用户.见下图:

Now fill the form and create user for database. See in image below :

现在，在代码中使用以下字符串进行连接:

Now, in the code use the following string for connection:

var mongoose = require('mongoose');

var mongoDB = "mongodb://<username>:<password>@ds241489.mlab.com:41489/<DB Name>";

mongoose.connect(mongoDB, {
    useMongoClient: true
});

var db = mongoose.connection;

db.on('error', console.error.bind(console, 'MongoDB connection error:'));
