我正在用mongo、express、angular和node创建我的第一个全栈web应用程序。我来自前端背景，在身份验证实现方面有点吃力。
我的（不完整的）应用程序工作了好几天，但今天它突然坏了，然后我神奇地修复了它。我很确定我没有对代码进行任何剧烈的更改。该错误导致所有经过身份验证的用户都看到"来宾用户"帐户。这将允许他们登录，但用户将以guestuser的身份从mongo返回。你看到我在这段代码中遗漏了什么吗？

假设您的大部分代码都是从这里获得的，我可以看到您对它进行了更改，这可能导致了失败。
passport.use(new LocalStrategy(
function(username, password, done) {
mongoose.model('User').findOne({ username: username }, function (err, user) {
您已经将validPassword添加到User，所以可能应该是
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({ username: username }, function (err, user) {
由于：
用户将作为访客从mongo返回
您可能应该在这里放置一些日志记录和/或错误处理：
passport.deserializeUser(function(id, done) {
User.findOne(id, function (err, user) {
done(err, user);
});
});
帮助你找到它。由于您才刚刚开始，如果您想探索在node/heroku中使用工具，我建议您查看winston和loggly。
用一句话来说，你的应用程序看起来非常"有弹性"——到处都是重定向。您看过fnakstad的节点/角度身份验证技术吗？（请注意，github页面引用了两篇解释内容的博客文章）。它可能会让你对如何控制局面有一些想法。
