app.get（＆＃39; /＆＃39;，function（req，res）{ var config = { 用户：＆＃39; sa＆＃39;，密码：＆＃39;＆＃39;，服务器：＆＃39; localhost＆＃39;，数据库：＆＃39; TestDB＆＃39; };

// 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);
    });
});

}）;
