Question

app.get('/', function (req, res) {
    var config = {
        //user: 'sa',
       // password: '',
        server: 'localhost',
        database: 'TestDB',
        debug: true
    };

    // connect to your database
    sql.connect(config, function (err) {

        if (err) console.log(err);

        // create Request object
        var request = new sql.Request();

        // query to the database and get the records
        request.query('select * from userInfo', function (err, recordset) {

            if (err) console.log(err)

            // send records as a response
            res.send(recordset);

            //console.log(recordset);
            sql.close();
        });
    });

});

我希望在没有用户和密码的情况下进行连接，并在通过命令提示符执行时出现此错误，并且有一些可信的连接查询我无法找到请帮助

请帮我解决此问题，并希望使用窗口身份验证连接此数据库

Answer 1

您可以尝试：

 options: {
        trustedConnection: true
    }

Answer 2

首先安装NPM Package，

npm install msnodesqlv8

然后将配置变量更改为

const sql = require('mssql/msnodesqlv8')
var config = {
    server: 'localhost',
    driver: 'msnodesqlv8',
    database: 'TestDB',
    debug: true,
    options: {
        trustedConnection: true
    }
};

使用nodejs连接数据库时出错
