我一直在搜索stackoverflow，原因是我的node.js（express）应用程序挂起了一些带有passport.js的帖子。
我一直在看两个问题：
More Passport.js woes - hangs on form submission
Passport (local) is hanging on Authentication
我创建用户的代码工作正常，如下所示：
passport.use('local-signup', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
},
function(req, email, password, done) {
if (email)
email = email.toLowerCase(); // Use lower-case e-mails to avoid case-sensitive e-mail matching
// asynchronous
process.nextTick(function() {
// if the user is not already logged in:
if (!req.user) {
User.findOne({
where: {
local_email: email
}
}).then(function(user) {
if (user){
return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
}else{
// create the user
User
.build({
local_email: email,
local_password: generateHash(password),
id: 1 //Normal activated user
})
.save()
.then(newUser => {
//Our newly crated user
return done(null, newUser);
})
.catch(error =>{
//Woops something went wrong
return done(error);
})
//var newUser = new User();
//newUser.localemail = email;
//newUser.localpassword = generateHash(password);
//User.create(newUser).then(function(newUser, created) {
// if (!newUser) {
// return done(err);
// }
// if (newUser) {
// return done(null, newUser);
// }
//});
}
});
// if the user is logged in but has no local account...
} else if ( !req.user.local.email ) {
// ...presumably they're trying to connect a local account
// BUT let's check if the email used to connect a local account is being used by another user
User.findOne({
where: {
localemail: email
}
}).then(function(user) {
if (err)
return done(err);
if (user){
return done(null, false, req.flash('loginMessage', 'That email is already taken.'));
// Using 'loginMessage instead of signupMessage because it's used by /connect/local'
} else {
// create the user
var newUser = new User();
newUser.local.email = email;
newUser.local.password = generateHash(password);
User.create(newUser).then(function(newUser, created) {
if (!newUser) {
return done(err);
}
if (newUser) {
return done(null, newUser);
}
});
}
});
} else {
// user is logged in and already has a local account. Ignore signup. (You should log out before trying to create a new account, user!)
return done(null, req.user);
}
});
}));
在我的路径文件中，该函数的帖子如下所示：
// process the signup form
app.post('/signup', passport.authenticate('local-signup', {
successRedirect : '/profile', // redirect to the secure profile section
failureRedirect : '/signup', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}));
我的登录代码不是很好用。 passport.js中的函数如下所示：
passport.use('local-login', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
},
function(req, email, password, done) {
if (email)
email = email.toLowerCase(); // Use lower-case e-mails to avoid case-sensitive e-mail matching
// asynchronous
process.nextTick(function() {
User.findOne({
where: {
local_email: email
}
}).then(function(user){
console.log("TEST: "+user);
// if no user is found, return the message
if (!user){
console.log("no user with the following email: " +email);
return done(null, false, req.flash('loginMessage', 'No user found.'));
}else if(!validPassword(password,user.local_password)){
console.log("wrong password");
return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.'));
// all is well, return user
}else{
return done(null, user);
return;
}
}).catch(function(err){
console.log("woops der skete en fejl: "+err);
console.log("email is: "+email);
console.log("password is: "+password);
return done(err);
});
});
}));
相应的路线如下：
// process the login form
app.post('/login', passport.authenticate('local-login', {
successRedirect : '/', // redirect to the secure profile section
failureRedirect : '/login', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}));
上面的代码在提交表单时挂起。如果我将代码更改为：
app.post('/login', function(req, res, next) {
passport.authenticate('local-login', function(err, user, info) {
if (err) { return next(err); }
if (!user) {
return res.render('/login', {
pageTitle: 'Sign in',
form: req.body
});
}
req.logIn(user, function(err) {
if (err) { return next(err); }
return res.redirect('/');
});
})(req, res, next);
});
我收到了500。 任何想法为什么这不起作用？
更新了控制台输出：
Executing (default): SELECT `id`, `role`, `local_email`, `local_password`, `facebook_id`, `facebook_token`, `facebook_email`, `facebook_name`, `twitter_id`, `twitter_token`, `twitter_displayname`, `twitter_username`, `google_id`, `google_token`, `google_email`, `google_name`, `createdAt`, `updatedAt` FROM `users` AS `users` WHERE `users`.`local_email` = 'test@local' LIMIT 1;
TEST: [object SequelizeInstance:users]
POST /login 302 87.021 ms - 46
Executing (default): SELECT `id`, `role`, `local_email`, `local_password`, `facebook_id`, `facebook_token`, `facebook_email`, `facebook_name`, `twitter_id`, `twitter_token`, `twitter_displayname`, `twitter_username`, `google_id`, `google_token`, `google_email`, `google_name`, `createdAt`, `updatedAt` FROM `users` AS `users` WHERE `users`.`id` = 1;
更新了passport.deserializeUser
passport.deserializeUser(function(id, done) {
/*User.findById(id, function(err, user) {
done(err, user);
});*/
User.findById(id).then(user => {
if (!user){
done(null);
}else{
done(user);
}
})
});
答案 0 :(得分：0)
您的passport.deserializeUser不正确。与所有Node.js回调一样，第一个参数是为错误保留的，如果没有任何错误，则应该是null（或另一个假值）。在您的情况下，您将user作为第一个参数传递，这使Passport认为存在错误。
试试这个：
passport.deserializeUser(function(id, done) {
User.findById(id)
.then(user => done(null, user))
.catch(done);
});
