인프런 커뮤니티 질문&답변

안녕하세요. passport local 로그인 실습을 하다가 막히는 부분이 있어 질문드립니다.

현재 postman으로 실험 시 회원가입은 정상적으로 진행이 되는 것 같은데,  postman으로 로그인 시도 시 다음과 같은 오류코드가 발생합니다.

(node:8940) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `—unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

(node:8940) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

 

PromiseRejectionWarning 부분이  async await 에러 핸들링을 안 해줘서 생긴다고 하는데, 교재에 나와있는대로 localstrategy부분의 에러 핸들링 부분은 교재와 비슷하게 적은 것 같은데...왜 오류가 나는지 잘 모르겠습니다ㅠㅠ

 

//localStrategy.js
const passport = require('passport');
const localStrategy = require('passport-local').Strategy;
const bcrypt = require('bcrypt');

const { user } = require('../models');

module.exports = () => {
    passport.use(new localStrategy({
        passReqToCallback : true,
        usernameField:'email',
        passwordField:'password',
    },
    async (email, password, done) => {
        try{
            const exUser = await user.findOne({where:{email}});
            if (exUser) {
                const result = await user.findOne({where:{password}});
                // const result = await bcrypt.compare(password, exUser.password);
                if(result){
                    done(null, exUser);
                } else {

위의 코드는 passport/localStrategy.js 파일이며,

 

아래 코드는 routes/auth.js 파일입니다.
