用户登录验证后呈现视图

Question

我正在尝试在输入成功凭据后登录验证表单创建会话后呈现视图。

此视图必须仅在登录程序后可访问，但是当我输入 url (127.0.0.1:3000/newsfeed) 时 'newsfeed' 页面已加载并绕过登录。我知道这可能是与路线相关的问题，但我无法让它发挥作用。

//session
app.use(session({
secret: 'secret',
resave: true,
saveUninitialized: true
}))

app.use(bodyParser.urlencoded({extended : true}));
app.use(bodyParser.json());

app.get('/', function(request, response) {
response.sendFile(path.join(__dirname + '/'));
});

// Checking credentials
app.post('/auth', function(request, response) {
var username = request.body.username;
var password = request.body.password;
if (username && password) {
    connection.query('SELECT * FROM accounts WHERE username = ? AND password 
= ?', [username, password], function(error, results, fields) {
        if (results.length > 0) {
            request.session.loggedin = true;
            request.session.username = username;
            response.redirect('authres');
        } else {
            response.send('Incorrect Username and/or Password!');
        }
        response.end();
    });
} else {
    response.send('Please enter Username and Password!');
    response.end();
}
});

//**Would like page to appear here instead of text**
app.get('/authres', function(request, response) {
if (request.session.loggedin) {
    response.send('Welcome back, ' + request.session.username + '!');


} else {
    response.send('Please login to view this page!');
}
response.end();
});

app.js

中的方法

//uses routes
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use('/newsfeed', newsfeedRouter);

index.js 登录路径

router.get('/', function(req, res, next) {
res.render('index');
});

newsfeed.js 新闻源页面的路由

router.get('/', function(req, res, next) {
res.render('newsfeed');
});

Answer 1

router.get('/', function(req, res, next) {
    res.render(req.session.loggedin?"newsfeed":"index");
});

如果用户已登录，这将呈现新闻源视图。
