发帖数: 7227 | 1 我老做了网站的login, logout，好像可以。问题是logout以后按browser back key，
尼玛以前只能login后看的内容又全出来了。
用了这个但还不行
app.get('/logout', isLoggedIn, function(req, res) {
req.logOut();
if (!req.user)
res.header('Cache-Control', 'private, no-cache, no-store, must-
revalidate');
res.redirect('/login');
}); | w*s

isAuthenticated() 还说 "you are logged in".
