Question

这是代码

createcar

我正在尝试在nodejs和猫鼬中进行认证

当用户按下登录时，当控件进入登录功能时，将使用电子邮件和密码的主体来调用api，它将检查数据库中是否存在电子邮件，并检查密码是否正确

在这里我得到的错误是 TypeError：无法读取未定义的属性'0'

显示错误消息

const {validationResult} = require('express-validator');
const bcrypt = require('bcryptjs');
const jwt = require('jsonwebtoken');
const User = require('../models/user');


exports.login = (req, res, next) => {
const email = req.body.email;
const password = req.body.password;
let loadedUser;
User.findOne({email:email})
.then(user => {
    if(user){
        loadedUser = user;
        return bcrypt.compare(password, user.password);
    } else{
        const error = new Error('EMAILID_NOT_FOUND');
        error.statusCode = 401;
        throw error;
    }

})

const app = express();

// app.use(bodyparser.urlencoded());

app.use(bodyparser.json()); //application/json

const message = error.message;
const data = error.data;

mongoose.connect('mongodb://localhost:27017/scope').then(result=>{
