Question

我正在创建一个模块节点会话。我已经编写了用于在节点js中创建会话的简单代码。我使用了session.js文件，另一个是index.html文件。我正在共享这两个文件代码，问题是当点击此URL http://localhost:8000/admin并单击登录链接然后再次重定向同一页面时，我不确定此内容中缺少什么。请帮助我！！！

session.js

var express = require('express');
var session = require('express-session');
var bodyParser = require('body-parser');
var app = express();


app.set('views', __dirname + '/view');
app.engine('html', require('ejs').renderFile);

app.use(session({ secret: 'ssshhhh', saveUninitialized: true, resave: true }));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

var sess;

app.get('/', function(req, res){
    sess = req.session;
    if(sess.email)
    {
        res.redirect('/admin');
    } else {

        res.render('index.html');
    }
});

app.post('/login', function(req, res) {
    sess = req.session;
    sess.email = req.body.email;
    res.end('done');
});

app.get('/admin', function (req, res){
    sess = req.session;
    if(sess.email)
    {
        res.write('<h1>Hello'+sess.email+'</h1><br>');
        res.end('<a href='+'/logout'+'>Logout</a>');
    }
    else
    {
        res.write('<h1>Please login first.</h1>');
        res.end('<a href='+'/'+'>Login</a>');
    }
});


app.get('/logout', function(req,res){
    req.session.destroy(function(err){
        if(err)
        {
            console.log(err);
        }
        else
        {
            res.redirect('/')
        }
    });
});

app.listen(8000, function(){
    console.log("App started on port 8000");
});

index.html

        var email, password;
        $('#submit').click(function(){

            email = $("#email").val();
            password = $("#password").val();
        });

        $.post("http://localhost:8000/login", {
            email: email,
            password: password }, function(data){
                if(data === 'done')
                {
                    window.location.href = "/admin";
                }
            });
    });
</script>

    Email <input type="text" id="email" name=""><br>
    Password <input type="password" id="password" name=""><br>
    <input type="submit" id="submit">

</html>

Answer 1

您的sess.email未被破坏，因此发生了，请在登录前先单击注销链接，以便会话将被破坏，并且您的条件if(sess.email)正常运行，我在<a href='+'/logput'+'>中发现了第二个问题，请纠正它。

//change href from /logput to /logout
res.end('<a href='+'/logput'+'>Logout</a>');
>> 
res.end('<a href='+'/logout'+'>Logout</a>');
