javascript - 从 MS Sql 请求表 - Node.js Web 服务

Question

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

总结手头的问题，如下所示:我目前正在使用 Windows 身份验证帐户登录 MS Sql Server Management - 这一切都很好，但是，我现在正在尝试构建一个 Web 服务，允许对于某些表的选择和交易，这是我现在遇到问题的地方，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，这里是错误码

** 一个有趣的注意事项是——

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

它实际上似乎没有传递我的登录信息 - 任何帮助将不胜感激，谢谢。

如果您尝试在 Node JS 中通过 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
        },     
    }
};
