 user  : 'root',
 password : '1996112lin',
 database : 'mydata',
 port:'3306'
});
connection.connect();
app.get('/',function (req,res) {
 res.sendfile(__dirname + "/" + "index.html" );
})
/**
 * 实现登录验证功能
 */
app.get('/login',function (req,res) {
 var name=req.query.name;
 var pwd=req.query.pwd;
 var selectSQL = "select * from user where uname = '"+name+"' and pwd = '"+pwd+"'";
 connection.query(selectSQL,function (err,rs) {
  if (err) throw err;
  console.log(rs);
  console.log('OK');
  res.sendfile(__dirname + "/" + "OK.html" );
 })
})
app.get('/register.html',function (req,res) {
 res.sendfile(__dirname+"/"+"register.html");
})
/**

 */
app.get('/register',function (req,res) {
 var name=req.query.name;
 var pwd=req.query.pwd;
 var user={uname:name,pwd:pwd};
 connection.query('insert into user set ?',user,function (err,rs) {
  if (err) throw err;
  console.log('ok');
  res.sendfile(__dirname + "/" + "index.html" );
 })
})
var server=app.listen(7744,function () {
 console.log("start");
})

Index.html:

 <!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Title</title>
</head>
<body>
  <form action="http://127.0.0.1:7744/login">
