无法连接到受密码保护的MongoDB服务器/数据库

Question

在针对本地mongoDB数据库成功测试了我的Node应用程序之后，我现在尝试连接到我们的服务器数据库-与我的本地mongoDB不同，该数据库受用户和密码保护。

尝试连接服务器时遇到问题。具体来说，我收到此错误：

  

MongoError：必须先连接MongoClient才能调用   MongoClient.prototype.db

我正在尝试的信誉看起来像这样：

{
  "MONGO_URL": "mongodb://myuser:mypassword@someurl.com:27017?authSource=admin",
  "MONGO_DATABASE": "bta",
  "MONGO_COLLECTION": "jobs"
}

这是我的连接代码：

const config = require('./configuration');
const url = config.get('MONGO_URL');
const dbName = config.get('MONGO_DATABASE');

const MongoClient = require('mongodb').MongoClient;
const client = new MongoClient(url);

async function getJobDetails() {
  client.connect(async function () {
    try {
      const db = await client.db(dbName);
      // do stuff
     });
    } catch (error) {
      console.log(error);
    }
  });
}

我在这里想念什么？

Answer 1

尝试：

const mongoClient = require('mongodb').MongoClient;

mongoClient.connect(url, { useNewUrlParser: true }, function(client_err, client) {
    if (client != null) {
        var client_db = client.db(dbName);
    }
    client.close();
});

Answer 2

作为MongoDB。 https://mongodb.github.io/node-mongodb-native/3.2/tutorials/connect/

并且请尝试仔细检查服务器上的数据库是否配置正确。

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');

// Connection URL with password example
const url = 'mongodb://user:password@address:27017?readPreference=primary&authSource=admin';

// Database Name
const dbName = 'myproject';

// Create a new MongoClient
const client = new MongoClient(url);

// Use connect method to connect to the Server
client.connect(function(err) {
  assert.equal(null, err);
  console.log("Connected successfully to server");

  const db = client.db(dbName);

  client.close();
});

这对两个有效的本地主机/服务器网址都有效

我弄清楚了问题所在，并且能够将其连接起来。问题在于该站点是安全的，因此我不得不在URL连接字符串中添加MERGE dbo.VipAbonentai vip USING (SELECT ab.abonentoID From Abonentas as ab Inner join Asmuo as A on ab.asmensID = A.asmensID Inner join Miestas as M on M.miestoID = M.miestoID Where M.miestoID = 1) WHEN MATCHED THEN UPDATE SET vip.abonentoID = ab.abonentoID, WHEN NOT MATCHED BY TARGET THEN INSERT (AbonentoID, asmensID, planoID, numeris, sutartiesPradzia, sutartiesPabaiga) VALUES (ab.AbonentoID, ab.asmensID, ab.planoID, ab.numeris, ab.sutartiesPradzia, ab.SutartiesPabaiga) ; ：
