Trying to run a web app (MEAN) on Amazon EC2 Instance but am encountering the following problem. Can anyone help me with this?

node app.js The Server has started on 9091

    username = username.replace('=', "=3D").replace(',', '=2C');

TypeError: Cannot read property 'replace' of undefined

推荐答案

猫鼬可以通过两种方式进行身份验证:

Mongoose can do auth in 2 ways:

1，连接字符串:mongoose.connect('mongodb://username:password@host:port(usually 27017)/db')其中username和password是该特定数据库的相应用户名和密码，host将是托管数据库的主机(因此localhost或某些域/IP)，port是mongo侦听的端口，db是该数据库的名称.您要连接的数据库

1, Connection string:mongoose.connect('mongodb://username:password@host:port(usually 27017)/db')Where username and password are the respective username and password for that specific db, host would be the host where your db is hosted (so localhost or some domain/IP), port is the port mongo listens on, and db is the name of the db you want to connect to

2，使用选项.从文档中:var options = { useMongoClinet: true, auth: {authdb: 'admin'}, user: 'myUsername', pass: 'myPassword',}mongoose.connect(uri, options);

2, Using options. From the docs:var options = { useMongoClinet: true, auth: {authdb: 'admin'}, user: 'myUsername', pass: 'myPassword',}mongoose.connect(uri, options);

在第一种方法中我也遇到了用户名未定义"错误，但是在第二种方法中我成功了.

I also faced the 'username undefined' error in the first approach, but I succeeded in the second approach.
