本文实例为大家分享了Node.js实现用户登录注册的具体代码，供大家参考，具体内容如下
IDE：WebStorm
工程目录：
数据库表
Login.js:
var express=require('express');
var app=express();
var mysql=require('mysql');
var connection = mysql.createConnection({
host : '127.0.0.1',
user : 'root',
password : '1996112lin',
database : 'mydata',
port:'3306'
});
connection.connect();
app.get('/',function (req,res) {
res.sendfile(__dirname + "/" + "index.html" );
})
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">
<input type="text" name="name"/>
<input type="text" name="pwd"/>
<input type="submit" value="提交"/>
</form>
<a href="register.html" rel="external nofollow" >注册</a>
</body>
</html>
Register.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="http://127.0.0.1:7744/register">
<input type="text" name="name"/>
<input type="text" name="pwd"/>
<input type="submit" value="提交"/>
</form>
</body>
</html>
启动后访问：http://localhost:7744/
