亲爱的，亲爱的，我会对nodejs发疯。我正在尝试使用Passport-Local和Sequelize库来实现由NodeJS支持的简单用户管理webapp的后端。现在我只是设计了用户模型。我遇到的主要问题是注册过程给我一个错误：看起来我正在处理一个未定义的对象。请有人帮我弄清楚发生了什么事吗？
这是我的代码（与我在互联网上找到的一些解决方案合并 - 显然没有任何作用，根据墨菲定律）。
如果代码字面上很糟糕，可以请Javascript程序员原谅我。我的理由是，这是我在Javascript中的第一次编程尝试，我必须为一个项目和最后一个（借口）做到这一点，但并非最不重要的是我在C和微芯片上长大。

EDIT 我忘记了护照策略。 passport.js
var bCrypt = require('bcrypt-nodejs');
module.exports = function(passport, user) {
var User = user;
var LocalStrategy = require('passport-local').Strategy;
console.log('debug: sono nella routine');
passport.use('local-signup', new LocalStrategy(
{
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(req, email, password, done) {
User.findOne({
where: {
email: email
}
}).then(function(user) {
if (user) {
return done(null, false, {message: req.flash('email already taken')});
console.log('mail already taken');
}
else {
var pass = generateHash(password);
var data =
{
email: email,
password: pass,
username: req.body.username,
public_key: '0',
last_login: null
};
User.create(data).then(function(newUser, created) {
if (!newUser) {
return done(null, false);
}
if (newUser) {
return done(null, newUser, {message: req.flash('tappost')});
}
next();
});
}
});
}
));
passport.deserializeUser(function(id, done) {
User.findById(id).then(function(user) {
if (user) {
done(null, user.get());
} else {
done(user.errors, null);
}
});
});
passport.serializeUser(function(user,done) {
done(null, user.id);
});
var generateHash = function(password) {
return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
};
答案 0 :(得分：0)
问题解决了。 ＆＃34;只是＆＃34;改变了如何在passport.js中引用模型如下
var User = user;
必须重写为
var User = db.user;
这里是最终护照策略文件
const db = require('./../models/');
var bCrypt = require('bcrypt-nodejs');
module.exports = function(passport) {
var User = db.user;
var LocalStrategy = require('passport-local').Strategy;
passport.use('local-signup', new LocalStrategy(
{
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(req, email, password, done) {
var generateHash = function(password) {
return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
};
User.findOne({
where: {
email: email
}
}).then(function(user) {
if (user) {
return done(null, false, {message: req.flash('email already taken')});
console.log('mail already taken');
}
else {
var pass = generateHash(password);
var data =
{
email: email,
password: pass,
username: req.body.username,
public_key: '0',
last_login: null
};
User.create(data).then(function(newUser, created) {
if (!newUser) {
return done(null, false);
}
if (newUser) {
return done(null, newUser, {message: req.flash('tappost')});
}
});
}
}).catch(function(err) {
console.log(err);
});
}
));
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id).then(function(user){
done(null, user);
}).catch(function(e){
done(e, false);
});
});
}
