[英]Using bcryptjs with Mongo
我正在尝试为我的Angular应用程序使用Bcrpyt加密用户密码,该应用程序在后端使用Mongodb。
这是代码
模型
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
bcrypt = require('bcryptjs'),
SALT_WORK_FACTOR = 10;
var UserSchema = new mongoose.Schema({
name: String,
username: { type: String, required: true, index: { unique: true } },
email: String,
password: { type: String, required: true },
created_at: Date,
topics: [{type: Schema.Types.ObjectId, ref: 'Topic'}],
posts: [{type: Schema.Types.ObjectId, ref: 'Post'}],
comments: [{type: Schema.Types.ObjectId, ref: 'Comment'}]
});
UserSchema.pre('save', function(next) {
var user = this;
// only hash the password if it has been modified (or is new)
if (!user.isModified('password')) return next();
// generate a salt
bcrypt.genSalt(SALT_WORK_FACTOR, function(err, salt) {
if (err) return next(err);
// hash the password along with our new salt
bcrypt.hash(user.password, salt, function(err, hash) {
if (err) return next(err);
// override the cleartext password with the hashed one
user.password = hash;
next();
});
});
});
UserSchema.methods.comparePassword = function(candidatePassword, cb) {
bcrypt.compare(candidatePassword, this.password, function(err, isMatch) {
if (err) return cb(err);
cb(null, isMatch);
});
};
mongoose.model('User', UserSchema);
在Controller内部创建和登录
var mongoose = require('mongoose');
var User = mongoose.model('User');
module.exports = (function() {
return {
login: function(req, res) {
User.findOne({email: req.body.email}, function(err, user) {
if(user === null) {
var error = "User not found"
console.log(error);
}
else{
user.comparePassword(req.body.password, function(err, isMatch){
if(err){
console.log("Password dont match");
} else{
console.log(user)
res.json(user);
}
})
}
})
},
create: function(req, res) {
var user = new User({name: req.body.name, username:req.body.username, email:req.body.email, password:req.body.password, created_at: req.body.created_at});
user.save(function(err) {
if(err) {
console.log('something went wrong');
} else {
console.log('successfully added a user!');
res.redirect('/');
}
})
}
})();
用户创建功能运行良好,保存了加密的密码。 但是在登录期间,它无法正确地将加密密码与输入进行比较。 允许用户通过而不管任何密码。
另外,如果找不到用户并且密码不匹配,我将如何显示错误(这是第二个Q.
主要担心甚至会接受错误的密码。
谢谢您的帮助。
您正在检查密码匹配过程中是否有任何错误,但不会检查输入的密码是否与哈希密码匹配。
user.comparePassword(req.body.password, function(err, isMatch){
if(err){
return console.log("Password dont match");
}
if (isMatch) {
// password matches. Log the user in
}
});
