无法与节点js中的MsSql数据库连接

Question

我无法与mssql服务器连接，执行编码时出现错误。

 exports.dbConfig = { // user: "sa", // password: "sa", // //server: "DESKTOP-QHBGOMQ", // server: '127.0.0.1', // //server: "localhost", // database: "ArduinoDataLogger", // port: 1433, // // connectionString: "Driver={SQL Server Native Client 11.0};Server=#{server}\\\\sql;Database=#{database};Uid=#{user};Pwd=#{password};" userName: 'sa', password: 'sa', server: 'DESKTOP-QHBGOMQ', database: 'ArduinoDataLogger', port: 1443, debug: true, driver: 'tedious', options: { port: 1443, encrypt: false, database: 'ArduinoDataLogger', useColumnNames: false, debug: { packet: true, data: true, payload: true, token: true, log: true } } }; 

我得到的错误是：

 ConnectionError: Failed to connect to DESKTOP-QHBGOMQ:1443 - Could not connect (sequence) at Connection.tedious.once.err (C:\\Users\\JanaVithu\\Desktop\\NewProject\\node_modules\\mssql\\lib\\tedious.js:237:17) at Connection.g (events.js:292:16) at emitOne (events.js:96:13) at Connection.emit (events.js:188:7) at Connection.socketError (C:\\Users\\JanaVithu\\Desktop\\NewProject\\node_modules\\tedious\\lib\\connection.js:1016:14) at C:\\Users\\JanaVithu\\Desktop\\NewProject\\node_modules\\tedious\\lib\\connection.js:861:25 at SequentialConnectionStrategy.connect (C:\\Users\\JanaVithu\\Desktop\\NewProject\\node_modules\\tedious\\lib\\connector.js:154:9) at Socket.onError (C:\\Users\\JanaVithu\\Desktop\\NewProject\\node_modules\\tedious\\lib\\connector.js:170:16) at emitOne (events.js:96:13) at Socket.emit (events.js:188:7) code: 'ESOCKET', originalError: 

我已启用tcp / ip，并且我所有的mssql服务器都在运行（自动）。 我什至更改了tcp / ip dynamic = 0 ..我真的不知道如何解决它，我已经尝试了专家（论坛）建议的所有可能的解决方案。

谢谢。 如果有人可以建议/帮助我解决此问题，那就太好了。

使用这些设置对我有用。

const config = {
  user: {user},
  password: {password},
  dialect: "mssql",
  server: {server},
  port:1435,
  database: {database},
  debug: true,  
  dialectOptions: {
    instanceName: 'SQLEXPRESS'
  }
};
sql.connect(config,function(err){
    if (err) console.log(err);
    console.log("SQL DATABASE CONNECTED");  
});

编辑

exports.dbConfig = {
    user: 'sa',
    password: 'sa',
    dialect: "mssql",
    server: 'DESKTOP-QHBGOMQ',
    database: 'ArduinoDataLogger',
    port: 1443, // check the port once again
    debug: true,
    dialectOptions: {
      instanceName: 'SQLEXPRESS'
    }
};
