尝试在Amazon EC2实例上运行Web应用程序(MEAN)但遇到以下问题。谁能帮我这个?
node app.js The Server has started on 9091
/opt/bitnami/apps/YelpCamp/node_modules/mongodb-core/lib/auth/scram.js:128
username = username.replace('=', "=3D").replace(',', '=2C');
^
TypeError: Cannot read property 'replace' of undefined

Mongoose可以通过两种方式进行身份验证:
1,连接字符串:
mongoose.connect('mongodb://username:password@host:port(usually 27017)/db')
其中用户名和密码是该特定数据库的相应用户名和密码,主机将是托管数据库的主机(因此localhost或某些域/ IP),端口是mongo侦听的端口,并且db是要连接的数据库的名称
2,使用选项。来自文档:
var options = {
useMongoClinet: true,
auth: {authdb: 'admin'},
user: 'myUsername',
pass: 'myPassword',
}
mongoose.connect(uri, options);
我在第一种方法中也遇到了“用户名未定义”错误,但我在第二种方法中取得了成功。
