下面是我如何与防爆preSS做.js文件：

1）检查，如果用户进行身份验证：我有一个名为CheckAuth中间件功能，我每天都需要用户进行身份验证航线上使用：

1) Check if the user is authenticated: I have a middleware function named CheckAuth which I use on every route that needs the user to be authenticated:

function checkAuth(req, res, next) {
  if (!req.session.user_id) {
    res.send('You are not authorized to view this page');
  } else {
    next();
  }
}

我用这个功能在我的路线是这样的：

I use this function in my routes like this:

app.get('/my_secret_page', checkAuth, function (req, res) {
  res.send('if you are viewing this page it means you are logged in');
});

2）的登录路径：

app.post('/login', function (req, res) {
  var post = req.body;
  if (post.user === 'john' && post.password === 'johnspassword') {
    req.session.user_id = johns_user_id_here;
    res.redirect('/my_secret_page');
  } else {
    res.send('Bad user/pass');
  }
});

3）注销路线：

app.get('/logout', function (req, res) {
  delete req.session.user_id;
  res.redirect('/login');
});      

如果您想了解更多关于防爆press.js这里查看他们的网站：前pressjs。 COM / guide.html
如果需要更复杂的东西，结账 everyauth （它有很多可用的身份验证方法，Facebook，微博等的;好的教程它这里）。

If you want to learn more about Express.js check their site here: expressjs.com/guide.html If there's need for more complex stuff, checkout everyauth (it has a lot of auth methods available, for facebook, twitter etc; good tutorial on it here).
