node.js - 数据库JWT中不存在用户？

问题描述

所以我在使用 JWT 令牌进行用户身份验证时遇到了一个小问题。当我登录时，它返回给我“用户不存在”，尽管数据库中显然有一个用户。我试图通过不在数据库中查找密码并进行比较来解决它并且它有效，但我的问题是我如何比较猫鼬数据库中的密码并检查用户是否存在？

登录路径：

//create route for sign in
router.post('/signin', async (req, res) => {
    //destructure email and password from req.body
    const user = await User.findOne({
        email: req.body.email,
        password: req.body.password,
    })
    if (!user) res.status(400).send({ message: 'User doesnt exist' })
    else {
        const valid = compare(req.body.password, user.password)
        if (!valid) res.send(400).send({ message: 'Password doesnt match' })

        if (valid) {
            const accesstoken = createAccessToken(user._id)
            const refreshtoken = createRefreshToken(user._id)
            return res.send({
            email: user.email,
            refreshtoken: user.refreshtoken,
            sendAccessToken: sendAccessToken(req, accesstoken),
            sendRefreshToken: sendRefreshToken(refreshtoken),
        })
        }
    }
})

用户型号：

const mongoose = require('mongoose')
// const SALT_WORK_FACTOR = 10
// const bcrypt = require('bcryptjs')

//how a user will be stored in the mongodb schema
const userSchema = new mongoose.Schema({
    name: { type: String, required: true, index: { unique: true } },
    email: { type: String, required: true, unique: true, dropDups: true },
    password: { type: String, required: true, minlength: 6, trim: true },
    isAdmin: { type: Boolean, required: true, default: false },
    refreshtoken: { type: String },
})

const userModel = mongoose.model('Users', userSchema)

module.exports = userModel

登录页面：

import React, { useState, useEffect, useContext } from 'react'
import { userContext } from '../../App'
// import { useDispatch, useSelector } from 'react-redux'
// import { login } from '../../actions/userActions'

function Login(props) {
    const [email, setEmail] = useState('')
    const [password, setPassword] = useState('')
    const [user, setUser] = useContext(userContext)
    //acces the userLogin from redux store
    // const userLogin = useSelector((state) => state.userLogin)
    // const { loading, userInfo, error } = userLogin

    // const dipsatch = useDispatch()
    // useEffect(() => {
    //     if (userInfo) {
    //         props.history.push('/')
    //     }
    // }, [userInfo])

    //handlesubmit
    const handleSubmit = async (e) => {
        e.preventDefault()
        const result = await (
            await fetch('http://localhost:5000/users/signin', {
                method: 'POST',
                credentials: 'include',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    email,
                    password,
                }),
            })
        ).json()
        if (result.accesstoken) {
            setUser({
                accesstoken: result.accesstoken,
            })
            window.location = '/'
        } else {
            alert(result.error)
        }
    }
    useEffect(() => {
        console.log(user)
    }, [user])
