[nodemon] app crashed - waiting for file changes before starting...
Here are my routes
这是我的路线
// Token URL :get
router.get('/users/reset/:token', (req, res) => {
User.findOne({
resetPasswordToken: req.params.token,
resetPasswordExpires: { $gt: Date.now() }
}, function(err, user) {
if (!user) {
req.flash('error', 'Password reset token is invalid or has expired.');
res.redirect('/users/forgot');
}
res.redirect('reset.hbs', {
pageTitle: 'Reset Your Password',
user: req.user
});
});
});
// Token URL :post
router.post('/users/reset/:token', (req, res, next) => {
if(req.body.password === req.body['password-confirm']) {
next();
return;
}
req.flash('error', 'Passwords do not match!');
res.redirect('back');
User.findOne({
resetPasswordToken: req.params.token,
resetPasswordExpires: { $gt: Date.now() }
}, function(err, user) {
if(!user) {
req.flash('error', ' Password reset is invalid or has expired');
res.redirect('/login');
}
const setPassword = promisify(user.setPassword, user);
setPassword(req.body.password);
user.resetPasswordToken = undefined;
user.resetPasswordExpires = undefined;
const updatedUser = user.save();
req.login(updatedUser);
req.flash('success_msg', 'Your password has been reset successfully! You are now logged in!');
res.redirect('/dashboard');
});
});
I think, I'm close to getting this to work, just a few errors I'm running into. This being one of them. I have checked the documentation and I'm not seeing anything mentioning status codes, I believe this is a change in the recent framework, seems quite odd having to define a status code for every redirect or render.
我想，我快要让它工作了，只是我遇到了一些错误。这是其中之一。我已经检查了文档，但没有看到任何提及状态代码的内容，我相信这是最近框架中的一个变化，必须为每个重定向或渲染定义一个状态代码似乎很奇怪。

You have to use res.renderinstead of res.redirect:
您必须使用res.render而不是res.redirect：
res.render('reset.hbs', {
pageTitle: 'Reset Your Password',
user: req.user
});
res.redirectmethod accept the route string as arguement while res.renderaccept a string that represent the file path of the view to render
res.redirect方法接受路由字符串作为参数，而res.render接受表示要渲染的视图的文件路径的字符串
