如何强制刷新req.user？

Question

我在我的node.js/express应用程序中使用带有本地身份验证策略的passport.js.

返回的用户LocalStrategy包括电子邮件和用户名等内容.

我想让用户能够在应用程序中更新他们的电子邮件或用户名.当发生这种情况时,我想告诉护照重新加载用户(类似于他们刚刚登录),以便req.user反映会话剩余部分的更新更改.简单地设置它似乎不会超过那个请求.

简化示例:

app.get('/changeEmail', function(req, res, next) {

    var userId = req.user.id;
    var origEmail = req.user.email;
    var newEmail = req.param('email');

    userDao.updateEmail(userId, newEmail, function(err) {
        if (!err) {
            // user's email has changed, need change reflected in req.user from this point on
            req.user.email = newEmail;
        }
        next();
    });

});

您应该能够logIn根据请求调用该方法.这将调用该serializeUser方法来更新会话.

userDao.updateEmail(userId, newEmail, function(err) {
    if (!err) {
        // user's email has changed, need change reflected in req.user from this point on
        var user = req.user;
        user.email = newEmail;
        req.logIn(user, function(error) {
            if (!error) {
                // successfully serialized user to session
            }
        });
    }
    next();
});
