Question

在通过Web服务（内置于Node.js中）向Microsoft SQL Server生成请求方面，我需要帮助。

总结一下眼前的问题，如下所示：我目前正在使用Windows身份验证帐户登录MS Sql Server管理-这都是find和dandy，但是，我现在尝试构建一个允许用于某些表的选择和事务处理，这是我现在遇到的问题，特别是在登录和将数据提取到Web服务方面。

代码

var express = require('express'); var app = express();
app.get('/',function(req,res) {
  const sql = require('mssql');
  // Connection Path
  const myServerPath = String("xxxx\\WS1SQLEXPRESS");
  // Connection String Parameter
  const config = {
      // User Login Details - Windows Auth or General User Account
      user    : 'xxxx-xxx\\AdrianH',
      password: 'xxxxxx',
      // Server path to connect to
      server  : myServerPath,
      // Database
      datebase: 'plex',
      options : {
        trustedConnection: true
      }
  };
  sql.connect(config,function(err) {
    if (err) console.log(err);
    // Create Request Object
    var request = new sql.Request();
    // Query the Database
    request.query('USE plex; SELECT * FROM [plex].[dbo].[tblWorkCenters]',function(err,recordset) {
      if (err) console.log(err)
      // send records as response
      res.send(recordset);
    });
  });
});
// Start Server and listen on //http://localhost:8001/
var server  = app.listen(3213,function(){
  console.log('Server is running...');
});

我隐藏了敏感信息，这是错误代码

**有趣的注释在-

(C:\Users\adrianh\node_modules\tedious\lib\token\stream-parser.js:80:14) message: 'Login failed for user \'\'.', code: 'ELOGIN' },
      name: 'ConnectionError' }

它似乎并没有传递我的登录信息-非常感谢您的帮助。

如果您试图通过节点JS中的Windows身份验证连接mssql，请使用此模块。

var mssql = require('mssql/msnodesqlv8

示例：

var mssql = require('mssql/msnodesqlv8')

var dbConfig = {    
    server: 'server',
    driver: 'msnodesqlv8',
    database: 'DBDATA', 
    port: '1433',
    options: {
        trustedConnection: true,              
        debug: {
            packet: false,
            payload: false,
            token: false,
            data: false
        },     
    }
};

从MS Sql请求表-Node.js Web服务
