MongoError：没有经过身份验证的用户

我正在尝试编写一个脚本来使用以下命令将管理员用户和通用用户添加到 MongoDB 数据库mongodbNodeJS 驱动程序 - 版本3.0.1

我可以创建数据库的管理员用户，但不能创建普通用户。我总是得到MongoError: there are no users authenticated。通过查看文档，验证用户身份的唯一方法是通过 URL。我已经从指定路径完全删除了数据库，尝试了多次，但仍然卡住了。

这是我到目前为止所得到的，

const MongoClient = require('mongodb').MongoClient;
const format = require('util').format;
const config = require("./config.json");

var adminUser = process.argv[2],
adminPassword = process.argv[3],
url = `mongodb://${config.database.location}:${config.database.port}`,
authURL = `mongodb://%s:%s@${config.database.location}:${config.database.port}/?authMechanism=SCRAM-SHA-1&authSource=admin`;

if (!adminUser || !adminPassword) {
   throw new Error("Please enter administrator username and password!\nUsage:\tnode init.js <adminUserName> <adminPassword>\n\n");
}

MongoClient.connect(url, function (err, client) {
    if (err) throw err;
    console.log("Connected successfully to server");
    const db = client.db(config.database.name);
    var adminDb = db.admin();
    adminDb.addUser(adminUser, adminPassword, {
        roles: [{
           role: "userAdminAnyDatabase",
           db: "admin"
        }]
    }).then(function (err, result) {
            MongoClient.connect(format(authURL, encodeURIComponent(adminUser), encodeURIComponent(adminPassword)), function (err, authClient) {
                  if (err) throw err;
                  console.log('Authenticated Successfully');
                  const db = client.db(config.database.name);
                  var adminDb = db.admin();
                  db.addUser(config.database.auth.username, config.database.auth.password, {
                         roles: [{
                             role: "readWrite",
                             db: config.database.name
                         }]
               }).then(function () {
                   console.log("Setup completed!");
                   authClient.close();
                   client.close();
               }).catch(function (err) {
                   throw err.stack;
        });
      });
   });
 });

这是我的mongod.cfg，配置文件mongod过程：

systemLog:
      destination: file
      path: D:\MongoDB\logs\mongod.log
storage:
      dbPath: D:\MongoDB\database
security:
      authorization: "enabled"

最后是配置文件，config.json:

{
  "database": {
    "location": "localhost",
    "name": "mongodb-test",
    "port": 27017,
    "auth": {
        "username": "testuser",
        "password": "welcome"
     }
   }
 }

解决办法是先关闭客户端，然后重新连接MongoDB。这次用新的client由返回connect.

上面代码的相关部分是：

.......
............
adminDb.addUser(adminUser, adminPassword, {
    roles: [{
        role: "userAdminAnyDatabase",
        db: "admin"
    }]
}).then(function (result) {
    if (result && result.user) {
        console.log("Admin user created successfully");
        client.close(); // close the previous connection!
    }
    MongoClient.connect(format(authURL, encodeURIComponent(adminUser), encodeURIComponent(adminPassword)), function (err, authClient) {
        if (err) throw err;
        console.log('Authenticated Successfully');
        const db = authClient.db() // this is important!
   ....
