我需要幫助解決這個問題。我已經登錄腳本,崩潰節點如果用戶名或密碼不數據庫,這裏的代碼:Node.js在MySQL查詢上崩潰
/* Login */
exports.login = function(req, res){
var post = req.body;
var mysql = require('mysql');
var db = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'root',
database : 'node01',
});
var selectStmt = 'SELECT * FROM users WHERE name = "' + post.user +'"';
db.connect();
db.query(selectStmt, function(err, rows, fields) {
if(err) throw err;
else if(rows[0].name == post.user && rows[0].password == post.password){
req.session.auth_id = rows[0].id;
req.session.user = rows[0].name;
res.redirect('/adminindex');
}
else res.redirect('/admin');
});
db.end();
};
和錯誤,我得到

關於如何解決此問題的任何想法?
不要把代碼和錯誤上一個單獨的網站 - 把它們放在你的問題! –
