从NodeJS创建mongoDB数据库用户

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017'; // MongoDB连接URL
const dbName = 'mydatabase'; // 数据库名称

MongoClient.connect(url, function(err, client) {
  if (err) throw err;
  console.log('Connected successfully to server');
  const db = client.db(dbName);
  
  // 在这里创建数据库用户
});

const username = 'myuser'; // 用户名
const password = 'mypassword'; // 密码
const roles = [{ role: 'readWrite', db: dbName }]; // 用户角色

db.addUser(username, password, { roles: roles }, function(err, result) {
  if (err) throw err;
  console.log('User created successfully');
  client.close();
});
