Question

我正在使用express模块和node.js创建网站。我使用mlab和mongodb创建数据库。但我认为我应该继续使用新的数据库，并且我删除了mlab中的旧数据库并创建了一个新数据库。

但是当我创建一个新的连接字符串时，它不再工作了。

const connStr = 'mongodb://<dbusername>:<dbpassword>@ds129454.mlab.com:29454/compinfo?authSource=compinfoB&w=1';
mongoose.connect(connStr, {useMongoClient: true });
mongoose.connection.on('error', console.error);

我已经在mlab上添加了用户，但是存在错误。
