Iam学习Sails和最后几天，我可以实现Passport Js身份验证，但今天出现了一个错误。这很奇怪，因为我做了同样的步骤，但现在，都失败了。我忘了安装一些依赖吗？
我不知道错误可能在哪里。 这是错误：

配置/ passport.js：
var passport = require('passport'),
LocalStrategy = require('passport-local').Strategy
bcrypt = require('bcrypt');
passport.use(new LocalStrategy(
function(email, password, done) {
User.findOne({ email: email }, function(err, user) {
if (err) { return done(err); }
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
}
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' });
}
return done(null, user);
});
}
));
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
module.exports = {
providers: {
'github': {},
'facebook': {},
'twitter': {}
},
http: {
customMiddleware: function(app){
console.log('Express midleware for passport');
app.use(express.static('public'));
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.session({ secret: 'keyboard cat' }));
app.use(passport.initialize());
app.use(passport.session());
app.use(app.router);
app.use(function(req,res,next){
// Set the loggedUser in locals
// to get it from the view
res.locals.loggedUser = req.user;
next();
});
}
}
};
模型/ user.js的：
module.exports = {
attributes: {
email: {
type: 'email',
unique: true
},
admin: {
type: 'boolean',
defaultsTo: false
},
password: {
type: 'string',
required: true
},
toJSON: function() {
var obj = this.toObject();
delete obj.password;
return obj;
},
// Check a password with the saved one.
validPassword: function(password, callback) {
var obj = this.toObject();
// If there are a callback, compare async.
if (callback) {
//callback (err, res)
return bcrypt.compare(password, obj.password, callback);
}
// Otherwise, compare sync.
return bcrypt.compareSync(password, obj.password);
},
hasPassword: function(){
return !!this.password;
}
},
// Lifecycle Callbacks
beforeCreate: function(values, next) {
hashPassword(values, next);
},
beforeValidation: function(values, next) {
if( values.new_password && values.confirm_password ) {
var newPasswordMatch = values.new_password === values.confirm_password;
if( newPasswordMatch ) {
User.findOne(values.id).done(function(err, user) {
if (err) return next(err);
if( !values.password || user.validPassword(values.password) ){
// If old password is valid.
// Ovewrite password with the new password.
values.password = values.new_password;
// delete new password and confirmation.
delete values.confirm_password;
delete values.new_password;
// Hash the password.
hashPassword(values, next);
}
});
}
} else if (values.id) {
// If we are updating the data but the password is not submited.
User.findOne(values.id).done(function(err, user) {
if (err) {
return next(err);
} else {
// Take the same password user had.
values.password = user.password;
next();
}
});
} else {
next();
}
},
beforeUpdate: function(values, next) {
if(values.password) hashPassword(values, next);
else next();
}
};
var bcrypt = require('bcrypt');
function hashPassword(values, next) {
bcrypt.hash(values.password, 10, function(err, hash) {
if (err) return next(err);
values.password = hash;
next();
});
};
答案 0 :(得分：0)
在passport.js
的顶部添加var express = require('express');
