获取bcrypt所需的错误数据和盐参数?

Question

我试图将用户保存到MongoDB如下，但我得到错误bcrypt错误:所需的数据和哈希参数。我已经检查了其他Dev在StackOverflow上问的相同错误问题，但它没有帮助。我附上了模型文件和路由器文件的代码。

1. 用户模型文件

const mongoose = require('mongoose');
const bcrypt = require('bcrypt');
const uSchema = new mongoose.Schema({
fullName: {
type: String,
required: true,
min: 4,
max: 30
},
email: {
type: String,
required: true,
trim: true,
unique: true,
index: true
},
hash_password: {
type: String,
required: true,
min: 6,
max: 12
},
role: {
type: String,
enum: ['user', 'admin', 'moderator'],
default: 'admin'
}
}, { timestamps: true });
uSchema.virtual('password')
.set(function (password) {
this.hash_password = bcrypt.hashSync(password, 10);
});
uSchema.methods = {
authenticate: function (password) {
return bcrypt.compareSync(password, this.hash_password);
}
}

module.exports = mongoose.model('User', uSchema);

2. 用户路由器文件

const express = require('express');
const router = express.Router();
const User = require('../models/user.model');
router.post('/login', (req, res) => {
});
router.post('/signin', (req, res) => {
User.findOne({ email: req.body.email })
.exec((error, user) => {
if (user) return res.status(400).json({
message: 'User already exists.'
});
const {
fullName,
email,
password
} = req.body;
const _user = new User({
fullName,
email,
password
});
_user.save((error, data) => {
if (error) {
return res.status(400).json({
message: 'Something went wrong'
});
} if (data) {
return res.status(201).json({
user: data
})
}
})
});
});
module.exports = router;

您可以在router文件中这样做。

const bcrypt = require("bcrypt")
// ...
router.post('/signin', (req, res) => { // Change this to signup
User.findOne({ email: req.body.email })
.exec((error, user) => {
if (user) return res.status(400).json({
message: 'User already exists.'
});
const {
fullName,
email,
password
} = req.body;
const hashedPassword = bcrypt.hashSync(password, 10);
const _user = new User({
fullName,
email,
hashedPassword
});
_user.save((error, data) => {
if (error) {
return res.status(400).json({
message: 'Something went wrong'
});
} if (data) {
return res.status(201).json({
user: data
})
}
})
});
});
module.exports = router;

并删除密码virtual。
