NodeJs mssql连接字符串

Question

我有一个问题，因为它出现错误SQL Server Network Interfaces: Connection string is not valid，连接字符串出了什么问题？

app.get('/', function (req, res) {

    var sql = require('mssql/msnodesqlv8');
    var config = {

      driver: 'msnodesqlv8',
      connectionString: 'Driver={SQL Server Native Client 11.0};Server={#{db_mydb.com},#{14400}};Uid={#{my_user}};Pwd={#{my_password}};Trusted_Connection={#{trusted}};',
    };
