我的node.js项目中的req.session.user不是“ global”

Question

身份验证成功后，req.session.user存在，但是当我尝试调用它来限制对页面的访问时，它消失了，当然，当我不想访问它时，它也限制了访问。 我知道这是一个范围问题，但无法解决。

    function restrict(req, res, next) {
  if (req.session.user) {
    next();
  } else {
    req.session.error = 'Access denied!';
    res.redirect('/accessdenied');
  }
}

// Add User Route
app.get('/addUser', restrict, function (req, res, next) 
  {res.render('addUser', {
                        title       : "SC Auds - Ad New User"
                     ,  author      : "Alan Swenson"
                     ,  description : "none"
                   });
                });



app.post('/login', function (req, res, next){

var checkuser = new User({
                      email     : req.body.user.email
                    , password  : req.body.user.password
                  });

 // checkuser.save(function(err) {
  // Successfully Logged In
User.getAuthenticated(checkuser.email, checkuser.password, function(err, user, reason) {

        if (err) {
          throw err;
        // Failed to work
          res.redirect('/error');
        }

        // login was successful if we have a user
        if (user) {
            // handle login success
            req.session.regenerate(function(){
            req.session.user = user;
            req.session.success = 'Authenticated as ' + user.email;
            res.redirect('/admin');
            console.log(req.session.user);
          });
        }

        // otherwise we can determine why we failed
        var reasons = User.failedLogin;
        console.log(User.failedLogin);
        switch (reason) {
            case reasons.NOT_FOUND:
            case reasons.PASSWORD_INCORRECT:
                // note: these cases are usually treated the same - don't tell
                // the user *why* the login failed, only that it did
                break;
            case reasons.MAX_ATTEMPTS:
                // send email or otherwise notify user that account is
                // temporarily locked
                break;

        }

    });



 });

这是我的app.js

Answer 1

您在这里缺少限制功能。

app.post('/login', function (req, res, next){

更改为。

app.post('/login', restrict, function (req, res, next){

Answer 2

我想到了。 由于计算机和服务器之间的时区不同，我的cookie立即到期。 更改为过期：false

cookie: {   secure: true, 
                  path: '/',
                expires: false}
