node.js – mLab认证上的MongoDB失败

根据此处的步骤创建了一个新的mLab帐户并创建了一个数据库.尝试使用mongo shell和mongoose Node.js模块连接到数据库,但我在两种情况下都看到“Authentication Failed”错误.

在Mongo sHell命令中,我已经仔细检查了凭据

@H_63_9@mongo ds012345.mlab.com:56789/dbname -u dbuser -p dbpassword

错误：

@H_63_9@mongoError: authentication fail at Function.MongoError.create (E:\Gatsby\notmongoose\node_modules\mongodb-core\lib\error.js:31:11)

使用Mongoose

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@L_454_6@mongoError：身份验证失败

还有什么需要在mLab控制台或其他任何我可能做错或丢失的事情上完成吗？

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:'));
