Question

我用命令

创建了mongodb用户

use admin
db.createUser(
    {
      user: "superuser",
      pwd: "12345678",
      roles: [ "root" ]
    }
)

然后在我的应用程序中，我试图连接像这样的猫鼬

var options = {
user: "superuser",
pass: "12345678"
};


var mongooseConnectionString = 'mongodb://localhost/twitter-mongo';

mongoose.connect(mongooseConnectionString,options);
mongoose.model('User', UserSchema);

var User = mongoose.model('User');

通过mongoose

插入数据时出现此错误

MongoError: not authorized for insert on twitter-mongo.users

请告诉我我的代码有什么问题

Answer 1

您必须在连接字符串中声明authSource参数，以指定包含您的用户凭据的数据库的名称：

var options = {
  user: "superuser",
  pass: "12345678",
  useMongoClient: true
};

var mongooseConnectionString = 'mongodb://localhost/twitter-mongo?authSource=admin';

请注意，我还设置了＆＃34; useMongoClient＆＃34;为真。这使使用MongoClient.connect验证身份验证和 open（）已弃用错误消息。

Answer 2

这很好用：

var options = { server: { socketOptions: { keepAlive: 1 } } };
var connectionString = 'mongodb://admin:admin1234@localhost:27017/myDB';

 mongoose.connect(connectionString, options);

//Add those events to get more info about mongoose connection:

// Connected handler
mongoose.connection.on('connected', function (err) {
  console.log("Connected to DB using chain: " + connectionString);
});

// Error handler
mongoose.connection.on('error', function (err) {
  console.log(err);
});

// Reconnect when closed
mongoose.connection.on('disconnected', function () {
   self.connectToDatabase();
});

我确实使用docker运行了mongo服务，然后使用此代码将mongoose连接到了它

mongoose.connect('mongodb://user:pass@localhost:port/MyDB?authSource=admin', {
    useNewUrlParser: true
})
.then(() => console.log('Connected to MongoDB ...'))
.catch(err => console.error('Could not connect to MongoDB:‌', err));

这等于

mongo --username user --password pass --authenticationDatabase admin --port 27017

在连接后，然后使用MyDB数据库对其执行查找，聚合，插入等操作

Answer 4

尝试

const mongooseConnectionString = 'mongodb://superuser:12345678@ localhost/twitter-mongo?authSource=admin'

Answer 5

您需要在要操作的数据库中创建用户，而不是在管理DB中创建用户。

使用此命令，

use twitter-mongo;
db.createUser({
  user: "superuser",
  pwd: "12345678",
  roles: [ "root" ]
});

相反，

use twitter-mongo
db.createUser({
  user: "superuser",
  pwd: "12345678",
  roles: [ "root" ]
});

Answer 6

mongoose.createConnection('mongodb://username:password@35.238.xxx.xxx:27017/dashboards?authSource=admin', {
   useNewUrlParser: true
}, (e) => {

    if (e) throw console.error('Error connecting to mongo database master');
    console.log('Connected to mongo database master.');

});

Answer 7

创建连接字符串的正确方法是 var connection = mongoose.createConnection("mongodb://username:pwd@hostip:port/dbname?authSource=admin", options);

请使用 authSource=admin 在连接字符串中进行身份验证。
