bcrypt错误:需要数据和哈希参数 [英] bcrypt Error: data and hash arguments required
问题描述
我收到一个bcrypt错误,声明需要数据和哈希参数,引用我的routes.js文件中的第44行。据我所知,我传递的信息是:bcrypt.compare的第一个参数是用户输入的密码,第二个参数是从db中检索的哈希密码。我做错了什么?
I am getting a bcrypt error stating that data and hash arguments are required, referencing line #44 in my routes.js file. From what I can tell, I am passing that information: the first parameter to bcrypt.compare is the user entered password, and the second is the hashed password retrieved from the db. What am I doing wrong?
bcrypt.compare(req.params.password, user.password, function...
routes.js
'use strict'
var express = require('express');
var router = express.Router();
var User = require('../app/models/user');
//password hashing
var bcrypt = require('bcrypt');
var count = 0;
router.use(function(req, res, next) {
count++;
console.log('API hit count = %s', count);
next();
});
// /users post(create new user) get(specific user)
router.route('/users')
.post(function(req,res) {
var user = new User();
user.username = req.body.username;
user.password = bcrypt.hashSync(req.body.password, 10);
//save the user and checkfor errors
user.save(function(err) {
if (err) {
res.send(err);
} else {
res.json({message: "User created!"});
}
});
})
router.route('/users/:username')
.get(function(req, res) {
var query = {
username: req.params.username,
};
User.findOne(query, function(err, user) {
if (err) {
res.send(err);
} else {
bcrypt.compare(req.params.password, user.password, function(err, res) {
if(err) {
console.log('Comparison error: ', err);
}
})
res.json(user);
}
});
})
推荐答案
bcrypt.compare
需要3个参数; passwordToCheck,passwordHash和回调。 (查看文档中的示例)
bcrypt.compare
takes 3 parameters; passwordToCheck, passwordHash, and a callback, respectively. (Check the documentation for examples)
此错误表示前两个参数中的一个或两个都为null或未定义。因此,请确保它们都正确传递。 (不是null或未定义)
This error means one or both of the first 2 parameters are either null or undefined. Therefore, make sure both of them are passed correctly. (Not as null or undefined)
